Description

FREQUENCY DEPENDENT RESIDUAL SIDE BAND CORRECTION FIELD OF THE DISCLOSURE [0001] Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for frequency dependent residual side band correction.

BACKGROUND [0002] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). [0003] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. "Downlink" (or "DL") refers to a communication link from the network node to the UE, and "uplink" (or "UL") refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and/or a wireless personal area network (WPAN) link, among other examples). [0004] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

DETAILED DESCRIPTION [0028] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim. [0029] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as "elements"). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. [0030] While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G). [0031] Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as a network node 110a, a network node 110b, a network node 110c, and a network node 110d), a UE 120 or multiple UEs 120 (shown as a UE 120a, a UE 120b, a UE 120c, a UE 120d, and a UE 120e), and/or other entities. A network node 110 is a network node that communicates with UEs 120. As shown, a network node 110 may include one or more network nodes. For example, a network node 110 may be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, a network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)). [0032] In some examples, a network node 110 is or includes a network node that communicates with UEs 120 via a radio access link, such as an RU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, a network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or a core network via a backhaul link, such as a CU. In some examples, a network node 110 (such as an aggregated network node 110 or a disaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and/or one or more DUs. A network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmission reception point (TRP), a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, the network nodes 110 may be interconnected to one another or to one or more other network nodes 110 in the wireless network 100 through various types of fronthaul, midhaul, and/or backhaul interfaces, such as a direct physical connection, an air interface, or a virtual network, using any suitable transport network. [0033] In some examples, a network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to a coverage area of a network node 110 and/or a network node subsystem serving this coverage area, depending on the context in which the term is used. A network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 having association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. A network node 110 for a femto cell may be referred to as a femto network node or an in-home network node. In the example shown in Fig. 1, the network node 110a may be a macro network node for a macro cell 102a, the network node 110b may be a pico network node for a pico cell 102b, and the network node 110c may be a femto network node for a femto cell 102c. A network node may support one or multiple (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a network node 110 that is mobile (e.g., a mobile network node). [0034] In some aspects, the terms "base station" or "network node" may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, a DU, an RU, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC, or a combination thereof. In some aspects, the terms "base station" or "network node" may refer to one device configured to perform one or more functions, such as those described herein in connection with the network node 110. In some aspects, the terms "base station" or "network node" may refer to a plurality of devices configured to perform the one or more functions. For example, in some distributed systems, each of a quantity of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to duplicate performance of at least a portion of the function, and the terms "base station" or "network node" may refer to any one or more of those different devices. In some aspects, the terms "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the terms "base station" or "network node" may refer to one of the base station functions and not another. In this way, a single device may include more than one base station. [0035] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (e.g., a network node 110 or a UE 120) and send a transmission of the data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. In the example shown in Fig. 1, the network node 110d (e.g., a relay network node) may communicate with the network node 110a (e.g., a macro network node) and the UE 120d in order to facilitate communication between the network node 110a and the UE 120d. A network node 1that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, or the like. [0036] The wireless network 100 may be a heterogeneous network that includes network nodes 110 of different types, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, or the like. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network 100. For example, macro network nodes may have a high transmit power level (e.g., 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 to 2 watts). [0037] A network controller 130 may couple to or communicate with a set of network nodes 110 and may provide coordination and control for these network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device. [0038] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. A UE 120 may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and/or any other suitable device that is configured to communicate via a wireless or wired medium. [0039] Some UEs 120 may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered a Customer Premises Equipment. A UE 120 may be included inside a housing that houses components of the UE 120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled. [0040] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed. [0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a network node 110 as an intermediary to communicate with one another). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the network node 110. [0042] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (4MHz – 7.125 GHz) and FR2 (24.25 GHz – 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a "Sub-6 GHz" band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a "millimeter wave" band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz – 300 GHz) which is identified by the International Telecommunications Union (ITU) as a "millimeter wave" band. [0043] The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz – 24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FRcharacteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz – GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band. [0044] With the above examples in mind, unless specifically stated otherwise, it should be understood that the term "sub-6 GHz" or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term "millimeter wave" or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. [0045] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive an indication of a first frequency allocation associated with the first UE and a second frequency allocation associated with a second UE; receive an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE; receive a frequency dependent residual side band (FDRSB) reference signal (RS) via the first frequency allocation and the second frequency allocation; and identify an FDRSB correction associated with the second UE based at least in part the FDRSB RS, the second frequency allocation, and the second modulation order. Additionally, or alternatively, the communication manager 140 may perform one or more other operations described herein. [0046] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 1may transmit an indication of a first frequency allocation associated with a first user equipment (UE) and a second frequency allocation associated with a second UE; transmit an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE; and transmit an FDRSB RS via the first frequency allocation and the second frequency allocation. Additionally, or alternatively, the communication manager 150 may perform one or more other operations described herein. [0047] As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1. [0048] Fig. 2 is a diagram illustrating an example 200 of a network node 110 in communication with a UE 120 in a wireless network 100, in accordance with the present disclosure. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 2and a modem 232. In some examples, a network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs, or one or more DUs. [0049] At the network node 110, a transmit processor 220 may receive data, from a data source 212, intended for the UE 120 (or a set of UEs 120). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 1based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS(s) selected for the UE 120 and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 2(e.g., T modems), shown as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), shown as antennas 234a through 234t. [0050] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive the downlink signals from the network node 110 and/or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), shown as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem 254. Each modem 254 may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 2may obtain received symbols from the modems 254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to a controller/processor 280. The term "controller/processor" may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE 120 may be included in a housing. [0051] The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294. [0052] One or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2. [0053] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by the modems 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and/or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., the controller/processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6-11). [0054] At the network node 110, the uplink signals from UE 120 and/or other UEs may be received by the antennas 234, processed by the modem 232 (e.g., a demodulator component, shown as DEMOD, of the modem 232), detected by a MIMO detector 2if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and provide the decoded control information to the controller/processor 240. The network node 110 may include a communication unit 2and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 1for downlink and/or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modem(s) 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and/or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., the controller/processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., with reference to Figs. 6-11). [0055] The controller/processor 240 of the network node 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform one or more techniques associated with FDRSB correction, as described in more detail elsewhere herein. For example, the controller/processor 240 of the network node 110, the controller/processor 280 of the UE 120, and/or any other component(s) of Fig. 2 may perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, and/or other processes as described herein. The memory 242 and the memory 2may store data and program codes for the network node 110 and the UE 120, respectively. In some examples, the memory 242 and/or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the network node 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the network node 110 to perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples. [0056] In some aspects, the first UE includes means for receiving an indication of a first frequency allocation associated with the first UE and a second frequency allocation associated with a second UE; means for receiving an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE; means for receiving an FDRSB RS via the first frequency allocation and the second frequency allocation; and/or means for identifying an FDRSB correction associated with the second UE based at least in part the FDRSB RS, the second frequency allocation, and the second modulation order. The means for the first UE to perform operations described herein may include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282. [0057] In some aspects, the network node includes means for transmitting an indication of a first frequency allocation associated with a first UE and a second frequency allocation associated with a second UE; means for transmitting an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE; and/or means for transmitting an FDRSB RS via the first frequency allocation and the second frequency allocation. The means for the network node to perform operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246. [0058] While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of the controller/processor 280. [0059] As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2. [0060] Deployment of communication systems, such as 5G NR systems, may be arranged in multiple manners with various components or constituent parts. In a 5G NR system, or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or a network equipment may be implemented in an aggregated or disaggregated architecture. For example, a base station (such as a Node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP, or a cell, among other examples), or one or more units (or one or more components) performing base station functionality, may be implemented as an aggregated base station (also known as a standalone base station or a monolithic base station) or a disaggregated base station. "Network entity" or "network node" may refer to a disaggregated base station, or to one or more units of a disaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof). [0061] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A disaggregated base station (e.g., a disaggregated network node) may be configured to utilize a protocol stack that is physically or logically distributed among two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed throughout one or multiple other network nodes. The DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU also can be implemented as virtual units, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among other examples. [0062] Base station-type operation or network design may consider aggregation characteristics of base station functionality. For example, disaggregated base stations may be utilized in an IAB network, an open radio access network (O-RAN (such as the network configuration sponsored by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of communication systems by separating base station functionality into one or more units that can be individually deployed. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented for at least one unit virtually, which can enable flexibility in network design. The various units of the disaggregated base station can be configured for wired or wireless communication with at least one other unit of the disaggregated base station. [0063] Fig. 3 is a diagram illustrating an example disaggregated base station architecture 300, in accordance with the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that can communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a Near-RT RIC 325 via an E2 link, or a Non-RT RIC 315 associated with a Service Management and Orchestration (SMO) Framework 305, or both). A CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as through F1 interfaces. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be simultaneously served by multiple RUs 340. [0064] Each of the units, including the CUs 310, the DUs 330, the RUs 340, as well as the Near-RT RICs 325, the Non-RT RICs 315, and the SMO Framework 305, may include one or more interfaces or be coupled with one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to one or multiple communication interfaces of the respective unit, can be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units can include a wired interface, configured to receive or transmit signals over a wired transmission medium to one or more of the other units, and a wireless interface, which may include a receiver, a transmitter or transceiver (such as an RF transceiver), configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units. [0065] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions can include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among other examples. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (for example, Central Unit – User Plane (CU-UP) functionality), control plane functionality (for example, Central Unit – Control Plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 can be logically split into one or more CU-UP units and one or more CU-CP units. A CU-UP unit can communicate bidirectionally with a CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 310 can be implemented to communicate with a DU 330, as necessary, for network control and signaling. [0066] Each DU 330 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers depending, at least in part, on a functional split, such as a functional split defined by the 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, among other examples. In some aspects, the DU 330 may further host one or more low PHY layers, such as implemented by one or more modules for a fast Fourier transform (FFT), an inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (which also may be referred to as a module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330, or with the control functions hosted by the CU 310. [0067] Each RU 340 may implement lower-layer functionality. In some deployments, an RU 340, controlled by a DU 330, may correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing an FFT, performing an iFFT, digital beamforming, or PRACH extraction and filtering, among other examples, based on a functional split (for example, a functional split defined by the 3GPP), such as a lower layer functional split. In such an architecture, each RU 3can be operated to handle over the air (OTA) communication with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU(s) 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration can enable each DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture. [0068] The SMO Framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO Framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO Framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an Ointerface). Such virtualized network elements can include, but are not limited to, CUs 310, DUs 330, RUs 340, non-RT RICs 315, and Near-RT RICs 325. In some implementations, the SMO Framework 305 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 311, via an O1 interface. Additionally, in some implementations, the SMO Framework 305 can communicate directly with each of one or more RUs 340 via a respective O1 interface. The SMO Framework 305 also may include a Non-RT RIC 315 configured to support functionality of the SMO Framework 305. [0069] The Non-RT RIC 315 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, Artificial Intelligence/Machine Learning (AI/ML) workflows including model training and updates, or policy-based guidance of applications/features in the Near-RT RIC 325. The Non-RT RIC 315 may be coupled to or communicate with (such as via an Ainterface) the Near-RT RIC 325. The Near-RT RIC 325 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an Einterface) connecting one or more CUs 310, one or more DUs 330, or both, as well as an O-eNB, with the Near-RT RIC 325. [0070] In some implementations, to generate AI/ML models to be deployed in the Near-RT RIC 325, the Non-RT RIC 315 may receive parameters or external enrichment information from external servers. Such information may be utilized by the Near-RT RIC 325 and may be received at the SMO Framework 305 or the Non-RT RIC 315 from non-network data sources or from network functions. In some examples, the Non-RT RIC 315 or the Near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the Non-RT RIC 315 may monitor long-term trends and patterns for performance and employ AI/ML models to perform corrective actions through the SMO Framework 305 (such as reconfiguration via an O1 interface) or via creation of RAN management policies (such as A1 interface policies). [0071] As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with regard to Fig. 3. [0072] Fig. 4 is a diagram illustrating an example 400 of a communication having FDRSB, in accordance with the present disclosure. As shown in Fig. 4, a network node 110 may transmit a communication to a UE 120. The network node 110 may use multiple antenna elements (also referred to as "antennas") to transmit the communication using beamforming. The communication may include signals transmitted via multiple time-frequency resources (e.g., via multiple subcarriers and/or resource blocks on one or more symbols and/or slots). [0073] As shown in Fig. 4, the network node 110 may receive multiple streams 4for transmission to the UE 120. The streams may include data and/or control signaling for transmission to the UE 120. A digital precoder 404 may receive the streams 402 and apply precoding to the streams 402. After applying the precoding to the streams 402, the digital precoder 404 may output digitally precoded streams 406. [0074] A set of IQ modulators 408 (e.g., IQ modulators 408A through IQ modulators 408N) may receive the digitally precoded streams 406 from the digital precoder 4(e.g., directly or indirectly). The IQ modulators 408 may modulate the digitally precoded streams 406 to map bits of the digitally precoded streams 406 to constellation points associated with bit values of the digitally precoded streams 406. For example, the IQ modulators 408 may apply modulation based at least in part on applying amplitudes, in a Q dimension and an I direction in an IQ plane, according to an MCS of communications to the UE 120. However, the IQ modulators 408 may cause FDRSB (e.g., an IQ mismatch, an FDRSB impairment, and/or FDRSB error) to the digital precoded streams 406 based at least in part on, for example, imperfections of the IQ modulators 408. This FDRSB may cause signaling on a first subcarrier to cause interference with a second subcarrier that is a mirror of the first subcarrier about a carrier frequency. For example, the first subcarrier may be a distance from the carrier frequency in a positive direction (e.g., above the carrier frequency), and the second subcarrier may be the same distance from the carrier frequency in a negative direction (e.g., below the carrier frequency). [0075] The IQ modulators 408 may provide modulated signals associated with the digitally precoded streams 406 to antenna elements 410 for transmission over the air to the UE 120. Based at least in part on digital precoding, the antenna elements 410 may transmit the modulated signals associated with the digitally precoded streams 406 via a transmission beam 412. In some examples, the antenna elements 410 may transmit the modulated signals via one or more transmission beams 412. As the modulated signals propagate over the air to the UE 120, channel conditions 414 may affect the modulated signals. For example, the channel conditions 414 may affect a signal-to-noise ratio (SNR) and/or a signal-to-interference-plus-noise ratio (SINR) of the modulated signals as received at the UE 120. [0076] The UE 120 may receive the modulated signals having effects from channel conditions 414. Additionally, based at least in part on transmission using the IQ modulators 408, the modulated signals may have FDRSB. The antenna elements 4may provide received streams 418 (e.g., the modulated signals having effects of channel conditions 414 and FDRSB) to a demodulator 420. In some examples, the demodulator 420 may be unable to correctly demodulate the received streams 418 based at least in part on the FDRSB associated with the IQ modulators 408. In these examples, the UE 120 and the network node 110 may consume power, processing, power, and/or communication resources to detect and correct demodulation errors or failures in the received streams 418. For example, the UE 120 may provide hybrid automatic repeat request (HARQ) acknowledgment (HARQ-ACK) feedback to indicate a demodulation and/or decoding error, which may trigger a retransmission of communications associated with the streams 402. [0077] As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4. [0078] Fig. 5 is a diagram illustrating an example 500 of a set of allocations having FDRSB, in accordance with the present disclosure. As shown in Fig. 5, signals transmitted in a first allocation (e.g., a first set of resource block and/or a first frequency bandwidth) may cause FDRSB (e.g., FDRSB impairment) to signals transmitted on a second frequency allocation that is mirrored about a carrier frequency from the first allocation. The second frequency allocation may be mirrored about the carrier frequency from the first allocation based at least in part on the first allocation including a first set of subcarriers (e.g., a set of resource blocks) that are a distance in a first direction from (e.g., above or below) the carrier frequency in a frequency domain and the second frequency allocation including a second set of subcarriers that are the same distance in a second direction from (e.g., below or above, and opposite from the first direction) the carrier frequency in the frequency domain. [0079] As shown in Fig. 5, a network node may provide an allocation 502 for a first UE, an allocation 504 for a second UE, an allocation 506 for a third UE, and an allocation 508 for the first UE (e.g., an additional allocation for the first UE). Each of the allocations may be described relative to a carrier frequency 510 (e.g., a center frequency of a total bandwidth used by the network node). The allocations may cause FDRSB at frequency ranges that are mirrored from the allocations about the carrier frequency 510. [0080] For example, the allocation 502 for the first UE may cause FDRSB 512 at a range of subcarriers that are a same distance from the carrier frequency 510 (e.g., above the carrier frequency 510) as a range of subcarriers of the allocation 502 (e.g., below the carrier frequency 510). Similarly, the allocation 504 may cause FDRSB 514, the allocation 506 may cause FDRSB 516, and the allocation 508 may cause FDRSB 518. [0081] Based at least in part on the FDRSB from the allocations, signaling within the allocation 508 may impair communications via the allocation 502, signaling within the allocation 506 may impair communications via the allocation 504, signaling within the allocation 504 may impair communications via the allocation 506, and signaling within the allocation 502 may impair communications via the allocation 508. [0082] As described, signals of the allocation 504 are associated with the second UE and cause FDRSB 514 impairments to the allocation 506 that is associated with the third UE. The third UE [0083] Based at least in part on the FDRSB 514 impairments being caused by signals that are outside of the allocation 506 associated with the third UE, the third UE may not have information for correcting the FDRSB 514 when receiving communications within the allocation 506. For example, the third UE may not be aware of whether a downlink communication overlaps in time with communications to the third UE. Additionally, or alternatively, the third UE may not be aware of whether any allocations to other UEs overlap with all or part of the allocation 506 for the third UE. Based at least in part on the third UE being unable to correct the FDRSB 514, the third UE may communicate with increased errors, which may consume power, computing, network, and/or communication errors to detect and correct. [0084] As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5. [0085] In some aspects described herein, a network node may inform UEs with an a-priori knowledge of at least part of a frequency division multiplexing (FDM) and/or spatial division multiplexing (SDM) allocation map of served UEs. In this way, a UE may use the a-priori knowledge by realizing at which sub-carriers an FDRSB leakage should be expected and thereby corrected and at which sub-carrier no FDRSB correction is required. In some aspects, the network node may further indicate to the UEs modulation orders used by other served UEs. [0086] In some aspects, a UE may use a physical layer (PHY) procedure for cancelling transmission FDRSB of a network node when multiple UEs are in communication with the network node via FDM-based communication and/or SDM-based communication with interference caused at mirrored frequency locations (e.g., mirrored about a carrier frequency). [0087] In some aspects, the network node may inform a group of UEs (e.g., that are served in FDM and/or SDM and/or simultaneously over a same time slot) of a UE allocation FDM map and an associated modulation order of one or more UEs of the group of UEs. In this way, a UE of the group of UEs may perform autonomous FDRSB correction (e.g., suppression), which may include suppression of FDRSB from signals to the UE and also FDRSB caused by signals to one or more UEs, of the group of UEs, transmitted at a mirrored frequency location (e.g., mirrored from an allocation of the UE about the carrier frequency). Based at least in part on the UE having information associated with allocation of additional UEs, the UE may correct FDRSB leaking from the additional UEs with mirrored allocations relative to the UE, which would reduce errors, improve a link budget, conserve network resources, and/or conserve power and computing resources that may have otherwise been used for communicating with increased error rates and/or reduced spectral efficiency. [0088] In some aspects, a network node may serve multiple UEs on a same beam via FDM-based communications. A signal allocated at sub-carrier f0 may be FDRSB impaired by an additional signal based at least in part on the additional signal being allocated at a mirror frequency –f0 (e.g., relative to a carrier frequency). In some aspects, the network node may provide an indication of the allocation of the additional signal to a UE allocated with the sub-carrier f0 so the UE is capable of performing FDRSB correction, based at least in part on the allocation of -f0, at the subcarrier f0. [0089] In some aspects, the network node may serve multiple UEs on different beams via SDM-based communications. A signal allocated at sub-carrier f0 on a first beam may be FDRSB impaired by an additional signal based at least in part on the additional signal being allocated at a mirror frequency –f0 on a second beam and/or being allocated on a same frequency f0. In some aspects, the network node may provide an indication of the allocation of the additional signal to a UE allocated with the sub-carrier f0 on the first beam, so the UE is capable of performing FDRSB correction, based at least in part on the allocation of -f0 or f0 on the second beam. [0090] In order to determine a bandwidth allocation of an FDRSB reference signal, the network node may perform a bandwidth allocation determination process. For example, the network node may allocate resources associated with an allocation map, with f1, f2, f3, f4 >0 ; f3 < f2 < f4 < f1. UEs having resources allocated may request an FDRSB reference signal. FDRSB impairment to a signal X(f) may be an additive scaled down mirror image, such as ? (? ) = ? (? ) + ??? _????? (? ) ⋅ ? ∗(−? ). For a UE to be able to estimate a level of a residual side band (e.g., RSB_level(f)) over frequencies allocated to the UE, the UE may use a reference signal at X(-f). To support the UE estimating the FDRSB, the network node may transmit an FDRSB reference signal on one or more symbols and/or slots to the UEs (e.g., FDM UEs and/or SDM UEs). The FDRSB reference signal may be allocated such that UEs receive the FDRSB reference signal on allocated subcarriers and associated mirrored subcarriers. [0091] Once the estimation stage is over and the UE obtains the ??? _????? (? ), and the UE may apply correction to received data slots. For example, the UE may perform an iterative correction to data received via allocated subcarriers. An initial correction may include calculating tentative hard decisions (HDs) on a modulation value (e.g., an IQ value). Q is the modulation order of either the observed UE or of the mirror neighbor UE (e.g., using information of an allocation map and/or an associated modulation order already provided by the network node), depending on a desired mirror frequency (–f) in the argument of ? ????????? (????????? 0)(−? ). For a subsequent iteration, ? ? ???????? (????????? ? )(? ) = ? (? ) − ??? _????? (? ) ⋅ ? ̂??∗(????????? ? −1)(−? ) and ? ̂??(????????? ? )(−? ) = ?? (? ????????? (????????? ? )(−? ), modulation_order = ? ). id="p-92" id="p-92"

[0092] The UE may use a-priori knowledge about a frequency domain allocation map, to improve the correction. For example, since the network node informed the UE of the frequency domain allocation map, if a mirror frequency Z(-f) contains no allocation, then the UE may avoid correcting Z(f) (e.g., equivalent to setting RSB_LEVEL(f)=0) since it does not suffer from FDRSB leakage because the mirror frequency is vacant. [0093] Fig. 6 is a diagram of an example 600 associated with FDRSB correction, in accordance with the present disclosure. As shown in Fig. 6, a network node (e.g., network node 110, a CU, a DU, and/or an RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may have established a wireless connection prior to operations shown in Fig. 6. [0094] As shown by reference number 605, the network node may transmit, and the UE may receive, configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC control elements (CEs), and/or downlink control information (DCI), among other examples. In some aspects, the configuration information may include an indication of one or more configuration parameters (e.g., already known to the UE and/or previously indicated by the network node or other network device) for selection by the UE, and/or explicit configuration information for the UE to use to configure the UE, among other examples. [0095] In some aspects, the configuration information may indicate that the UE is to transmit a capabilities report that indicates whether the UE supports FDRSB correction at the UE. In some aspects, the configuration information may indicate that the UE is to indicate support for FDRSB correction at the UE. For example, the configuration information may indicate that the UE is to indicate support for FDRSB correction at the UE based at least in part on receiving an FDRSB reference signal on frequency resources that are mirrored about a carrier frequency from a frequency allocation of the UE. [0096] The UE may configure itself based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information. [0097] As shown by reference number 610, the UE may transmit, and the network node may receive, an indication of support for FDRSB correction at the UE. For example, the UE may indicate support for FDRSB correction using an FDRSB signal associated with an additional UE (e.g., a second UE). [0098] As shown by reference number 615, the UE may receive, and the network node may transmit, an indication of a first frequency allocation associated with the UE and a second frequency allocation associated with an additional UE. In some aspects, the network node may transmit an indication of an allocation map that includes frequency allocations associated with multiple UEs. In some aspects, the network node may transmit an indication of a same allocation map to all UEs having allocations within a frequency bandwidth and/or within a same beam or within an associated beam (e.g., a beam expected to create FDRSB for a beam associated with the UE). [0099] In some aspects, the UE may receive the indication of the second frequency allocation associated with the additional UE based at least in part on the additional UE being configured to receive communications from a network node via a same transmission beam as the first UE. For example, the first frequency allocation may include at least a first portion that is higher than a carrier frequency of a component carrier of the first frequency allocation and the second frequency allocation with the first portion being higher by a first distance. The second frequency allocation may include at least a second portion that is lower than the carrier frequency by the first distance (e.g., the same distance by which the first portion is higher than the carrier frequency). [0100] In some aspects, the UE may receive the indication of the second frequency allocation associated with the additional UE based at least in part on the additional UE being configured to receive communications from a network node via a neighbor beam and the second frequency allocation being on a same or mirrored frequency range from the first allocation. For example, the UE may be configured to receive communications from a network node via a first transmission beam and the additional UE is configured to receive communications from the network node via a second transmission beam, with the first frequency allocation and the second frequency allocation at least partially overlapping, or at least partially located at mirrored locations from a carrier frequency of a component carrier of the first frequency allocation and the second frequency allocation. [0101] As shown by reference number 620, the UE may receive, and the network node may transmit, an indication of a first modulation order associated with the UE and a second modulation order allocation with the additional UE. In some aspects, the UE may receive the indications of the modulation orders and the indications of the frequency allocations via a single message from the network node. [0102] In some aspects, the UE may receive an indication of the allocation of resources associated with reception of the FDRSB RS along with the indication of reference number 615 and/or the indication of reference number 620. For example, the UE may receive a single message that indication the second frequency allocation, the second modulation order, and/or the allocation of resources associated with reception of the FDRSB RS, among other examples. [0103] As shown by reference number 625, the UE may receive, and the network node may transmit, an FDRSB RS via the first frequency allocation and the second frequency allocation. For example, the UE may receive the FDRSB RS via the second frequency allocation based at least in part on the second frequency allocation being a mirror of the first frequency allocation. In some aspects, the second frequency allocation may include a first portion allocated to a first UE and a second portion allocated to a second UE. [0104] As shown by reference number 630, the UE may identify an FDRSB correction associated with the additional UE. In some aspects, the UE may identify the FDRSB correction associated with the additional UE based at least in part on receiving the FDRSB RS via the second frequency allocation. In some aspects, the FDRSB correction associated with the second UE may be based at least in part the FDRSB RS, the second frequency allocation, and/or the second modulation order, among other examples. [0105] As shown by reference number 635, the UE may receive, and the network node may transmit, a communication via the first allocation. The communication may include data that is modulated based at least in part on the first modulation order. In some aspects, signals associated with the communication may have FDRSB impairment based at least in part on signals transmitted within the second frequency allocation. [0106] As shown by reference number 640, the UE may apply FDRSB correction. For example, the UE may apply the FDRSB correction to signaling received via the first frequency allocation. In some aspects, the UE may apply the FDRSB correction to the communication on one or more subcarriers having a mirrored allocation (e.g., signals on subcarriers that are mirrored about the carrier frequency). In some aspects, the UE may refrain from applying FDRSB correction to the communication on one or more additional subcarriers having no mirrored allocation. id="p-107" id="p-107"

[0107] In some aspects, application of the FDRSB correction includes estimating, using hard decision estimations, a modulated IQ value of the signaling of the communication based at least in part on the FDRSB correction. In some aspects, the application of the FDRSB correction includes iterative FDRSB corrections of the signaling of the communication. [0108] As shown by reference number 645, the UE may receive an additional FDRSB RS. For example, the UE may receive the additional FDRSB RS on the second frequency allocation. In some aspects, the UE may receive the additional FDRSB RS on a third frequency allocation based at least in part on an update to the first frequency allocation, with the third frequency allocation being mirrored from the updated first frequency allocation. [0109] In some aspects, the UE may receive the additional FDRSB RS based at least in part on a change in communication parameters, a change in channel conditions, and/or a change in environmental conditions, among other examples. For example, the UE may receive the additional FDRSB RS based at least in part on a change of the first modulation order, a change of the second modulation order, a change of an allocation associated with the second UE, an expiration of a period of time after reception of the FDRSB RS, a change in channel conditions, a change in temperature, or an indication from a network node (e.g., based at least in part on network node detection of a change in communication parameters, a change in channel conditions, and/or a change in environmental conditions, among other examples), among other examples. [0110] As shown by reference number 650, the UE may identify an updated FDRSB correction associated with the additional FDRSB RS. [0111] Based at least in part on the UE having information associated with allocation of one or more additional UEs, the UE may correct FDRSB leaking from the one or more additional UEs with mirrored allocations relative to the UE, which would reduce errors, improve a link budget, conserve network resources, and/or conserve power and computing resources that may have otherwise been used for communicating with increased error rates and/or reduced spectral efficiency. [0112] As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with respect to Fig. 6. [0113] Fig. 7 is a diagram illustrating an example 700 of a set of allocations having FDRSB, in accordance with the present disclosure. Signals transmitted in a first allocation (e.g., a first set of resource block and/or a first frequency bandwidth) may cause FDRSB (e.g., FDRSB impairment) to signals transmitted on a second frequency allocation that is mirrored about a carrier frequency from the first allocation. The second frequency allocation may be mirrored about the carrier frequency from the first allocation based at least in part on the first allocation including a first set of subcarriers (e.g., a set of resource blocks) that are a distance in a first direction from (e.g., above or below) the carrier frequency in a frequency domain and the second frequency allocation including a second set of subcarriers that are the same distance in a second direction from (e.g., below or above, and opposite from the first direction) the carrier frequency in the frequency domain. [0114] As shown in Fig. 7, an allocation 702 for a first UE may include a range of frequencies between -f1 and -f2. An allocation 704 for a second UE may include a range of frequencies between -f2 and f3. An allocation 706 for a third UE may include a range of frequencies between f3 and f2. An allocation 708 for the first UE (e.g., an additional allocation for the first UE) may include a range of frequencies between f2 and f4 (which is lower than f1). The allocations may include ranges of frequencies around a carrier frequency (e.g., a center frequency) of a bandwidth used for communication with the network node. There may be additional allocations outside of the frequency ranges shown in Fig. 7. [0115] For a UE to be able to estimate the RSB_level(f) over frequencies allocated to the UE, the UE may use a reference signal at X(-f). In some aspects, the network node may transmit an FDRSB RS in a symbol and/or slot to first UE, the second UE, and/or the third UE (e.g., FDM UEs and/or SDM UEs). The FDRSB may be allocated with sub-carriers over (f2, f4) and –(f2, f4) allocated for the first UE to use for self-FDRSB estimation. Additionally, or alternatively, sub-carriers over (-f3, f3) may be allocated for the second UE to use for self-FDRSB estimation. Sub-carriers over (f3, f2) and –(f3, f2) may be allocated to the second UE and to the third UE for cross-FDRSB estimation. Remaining sub-carriers may be left turned off (e.g., without transmission and/or an allocation for RSs). [0116] Based at least in part on the UE having information associated with allocation of one or more additional UEs, the UE may correct FDRSB leaking from the one or more additional UEs with mirrored allocations relative to the UE, which would reduce errors, improve a link budget, conserve network resources, and/or conserve power and computing resources that may have otherwise been used for communicating with increased error rates and/or reduced spectral efficiency. id="p-117" id="p-117"

[0117] As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with respect to Fig. 7. [0118] Fig. 8 is a diagram illustrating an example process 800 performed, for example, by a UE, in accordance with the present disclosure. Example process 800 is an example where the UE (e.g., UE 120) performs operations associated with frequency dependent residual side band correction. [0119] As shown in Fig. 8, in some aspects, process 800 may include receiving an indication of a first frequency allocation associated with the first UE and a second frequency allocation associated with a second UE (block 810). For example, the UE (e.g., using communication manager 140 and/or reception component 1002, depicted in Fig. 10) may receive an indication of a first frequency allocation associated with the first UE and a second frequency allocation associated with a second UE, as described above. [0120] As further shown in Fig. 8, in some aspects, process 800 may include receiving an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE (block 820). For example, the UE (e.g., using communication manager 140 and/or reception component 1002, depicted in Fig. 10) may receive an indication of a first modulation order associated with the first UE and a second modulation order associated with the second UE, as described above.

[0122] As further shown in Fig. 8, in some aspects, process 800 may include identifying an FDRSB correction associated with the second UE based at least in part the FDRSB RS, the second frequency allocation, and the second modulation order (block 840). For example, the UE (e.g., using communication manager 140 and/or communication manager 1008, depicted in Fig. 10) may identify an FDRSB correction associated with the second UE based at least in part the FDRSB RS, the second frequency allocation, and the second modulation order, as described above. id="p-123" id="p-123"

[0132] In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the single message comprises an allocation of resources associated with reception of the FDRSB RS. [0133] Although Fig. 8 shows example blocks of process 800, in some aspects, process 800 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 8. Additionally, or alternatively, two or more of the blocks of process 800 may be performed in parallel. [0134] Fig. 9 is a diagram illustrating an example process 900 performed, for example, by a network node, in accordance with the present disclosure. Example process 900 is an example where the network node (e.g., network node 110) performs operations associated with FDRSB correction. [0135] As shown in Fig. 9, in some aspects, process 900 may include transmitting an indication of a first frequency allocation associated with a first UE and a second frequency allocation associated with a second UE (block 910).
