Technical Field
Embodiments relate to wireless communications. Some embodiments relate to a fifth generation (5G) system and radio access network 1(RAN 1). Some embodiments relate to Uplink Control Information (UCI) channel coding on a 5G physical uplink control channel (xPUCCH).
Background
In cellular networks, a User Equipment (UE) needs to communicate with an evolved NodeB (eNB), e.g., to provide Uplink Control Information (UCI). The UE transmits UCI to the eNB using a Physical Uplink Control Channel (PUCCH).
Therefore, there is a general need for systems and methods for UCI channel coding on PUCCH.

Detailed Description
The following description and the annexed drawings set forth in detail certain illustrative embodiments sufficiently to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in or substituted for those of others. Embodiments set forth in the claims encompass all available equivalents of those claims.
Mobile communications have evolved from early voice systems to the current highly sophisticated integrated communication platforms. Fifth generation (5G) wireless communication network systems provide access to information and sharing of data, etc. at many different locations and times by various users and applications. 5G network systems aim to meet the demands for performance dimensions and services that are very different and sometimes conflicting with each other. These requirements are driven by the different services or applications of the 5G network system that the user desires. In general, with some exceptions, 5G was developed from the third generation partnership project (3GPP) Long Term Evolution (LTE) and new Radio Access Technologies (RATs) were added to the 3GPP LTE.
Fig. 1A-1B are block diagrams of Time Division Duplex (TDD) subframe structures 100A and 100B in the Downlink (DL) according to some embodiments. The subframe structure 100A of fig. 1A is a low-latency structure, and the subframe structure 100B of fig. 1B is a high-throughput structure.
As shown in fig. 1A, the subframe structure 100A includes a 5G physical downlink control channel (xPDCCH)110A, a 5G physical downlink shared channel (xPDSCH)120A, a Guard Time (GT)130A, and a 5G physical uplink control channel (xPUCCH) 140A. Blocks 110A, 120A, 130A, and 140A are within a single subframe 150A. As shown in fig. 1B, subframe structure 100B is similar to subframe structure 100A, including xPDCCH 110B, xPDSCH 120B, GT 130B, and xPUCCH 140B. Unlike the subframe structure 110A, in the subframe structure 100B, the blocks 110A, 120A, 130A, and 140A are divided between two subframes 150B-1 and 150B-2. Subframe 150B-1 includes a portion of xPDCCH 110B and xPDSCH 120B. Subframe 150B-2 includes the remainder of xPDSCH 120B, GT 130B, and xPUCCH 140B.
To enable low delay transmission for enhanced mobile broadband communications, a self-contained TDD subframe 150A may be introduced, as shown in fig. 1A. Fig. 1A-1B illustrate two types of self-contained TDD subframe structures 100A/100B in the DL. For these subframe structures 100A/100B, xPDSCH 120A/120B is scheduled by xPDCCH110A/110B and is transmitted immediately after xPDCCH 110A/110B. GT 130A/130B is inserted or not inserted between xPDSCH 120A/120B and xPUCCH140A/140B in order to accommodate DL-to-Uplink (UL) and UL-to-DL handover times and round trip propagation delays.
To increase the data rate, two or more subframes 150B-1 and 150B-2 may be aggregated for one xPDSCH 120B transmission for a User Equipment (UE) (e.g., as discussed in connection with fig. 2). As shown in fig. 1B, xPDSCH 120B spans two subframes 150B-1 and 150B-2 in high throughput structure 100B. GT 130B is inserted into second subframe 150B-2. In this case, the GT overhead can be reduced by half compared to the low delay structure 100A of fig. 1A. In some cases, additional xpdcchs (other than xPDCCH 110B) are inserted in subframe 150B-2 to allow the same subframe scheduling for DL data channel transmission. As shown in FIG. 1B, subframe structure 100B spans two subframes 150B-1 and 150B-2. However, in some cases, the subframe structure 100B spans more than two subframes, with xPDSCH 120B extending across additional subframes.
According to some examples, in LTE, the PUCCH is transmitted in a frequency region on the edge of the system bandwidth. In addition, the PUCCH and the Physical Uplink Shared Channel (PUSCH) are multiplexed in a Frequency Division Multiplexing (FDM) manner. However, as shown in fig. 1A-1B, xPUCCH 110A/110B and data channels are multiplexed in a Time Division Multiplexing (TDM) manner. In the case where Uplink Control Information (UCI) includes hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK) feedback or Channel State Information (CSI) reports (e.g., Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and Rank Indicator (RI)), different xPUCCH formats are defined according to different payload sizes. In some embodiments, the subject technology proposes a specific xPUCCH format for carrying UCI with various payload sizes.
As described above, the xPUCCH is used to carry uplink control information, which may include scheduling request, HARQ ACK/NACK feedback, CSI report, and beam related information. Various xPUCCH formats may be defined according to a payload size.
In one example, xPUCCH format 1/1a/1b is used to carry scheduling requests and 1 or 2 bit HARQ ACK/NACK feedback.
In one example, xPUCCH format 2 is used to carry scheduling requests, HARQ ACK/NACK feedback for multiple HARQ processes, CSI reports and/or beam related information. The payload size is between 3 and 13 bits.
In one example, xPUCCH format 3 is used to carry scheduling requests, HARQ ACK/NACK feedback for multiple HARQ processes, CSI reports and/or beam related information. The payload size is between 3 and 22 bits.
In one example, xPUCCH format 4 is used to carry scheduling requests, HARQ ACK/NACK feedback for multiple HARQ processes, CSI reports and/or beam related information. The payload size is greater than 22 bits.
In some embodiments, one physical Resource Block Group (RBG) corresponds to six Physical Resource Blocks (PRBs), which is the smallest resource unit for xPUCCH transmission. In this case, the eNode B (eNB) may schedule the UE to transmit xPUCCH using one or more RBGs according to the indication in the Downlink Control Information (DCI) (see discussion of fig. 2 for details of the operation of the UE and eNB).
The physical uplink control channel xPUCCH carries uplink control information. In some cases, xPUCCH is transmitted in the last symbol of a subframe. All xPCCH formats use cyclic shiftWhich varies with the number of slots according to equation 1.
In the case of the equation 1, the,is a cell-specific cyclic shift value;is the number of symbols in one slot; n issIs the slot number within a frame. For 5G, nsIn the range of 0 to 99.

Fig. 2 illustrates an example of portions of an end-to-end network architecture of a Long Term Evolution (LTE) network 200 having various components of the network, in accordance with some embodiments. As used herein, LTE networks refer to LTE and LTE-advanced (LTE-a) networks and other releases of LTE networks to be developed. Network 200 may include a Radio Access Network (RAN) (e.g., as shown, E-UTRAN or evolved universal terrestrial radio access network) 201 and a core network 220 (e.g., shown as Evolved Packet Core (EPC)) coupled together by an S1 interface 215. For convenience and brevity, only portions of the core network 220 and the RAN 201 are shown in this example. The network 200 includes a UE202 configured to determine uplink control information for xPUCCH; and encode a transmission of xPUCCH to carry the determined uplink control information to the allocated resources, wherein the determined uplink control information comprises one or more of: scheduling request, hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK) feedback, Channel State Information (CSI) reporting, and beam related information. UE202 is configured to access a 5G physical uplink control channel (xPUCCH) format for transmitting Uplink Control Information (UCI), wherein the xPUCCH format corresponds to a payload size of the xPUCCH; accessing UCI, wherein data in the UCI comprises one or more of hybrid automatic repeat request (HARQ) Acknowledgements (ACKs), Scheduling Requests (SRs), Channel Quality Indicators (CQIs), Precoding Matrix Indicators (PMIs), Rank Indicators (RIs), and Beam Indicators (BI); and encoding the UCI based on the xPCH format and the data in the UCI. The network 200 includes an eNB 204. One or more of enbs 204 are configured to access xpucchs from a plurality of User Equipments (UEs), including UEs with two antenna ports; and multiplexing the accessed xpucchs, wherein ZC sequences having different cyclic shift values are applied on the xpucchs received from each antenna port for a UE configured with two antenna ports. In some examples, UE202 transmits xPUCCH to eNB204, which receives xPUCCH from UE 202.
The core network 220 may include a Mobility Management Entity (MME)222, a serving gateway (serving GW)224, and a packet data network gateway (PDN GW) 226. RAN 201 may include an evolved node B (eNB)204 (which may operate as a base station) for communicating with User Equipment (UE) 202. The enbs 204 may include a macro eNB204a and a Low Power (LP) eNB204 b.
The MME 222 may be similar in function to the control plane of a conventional Serving GPRS Support Node (SGSN). The MME 222 may manage mobility aspects in access such as gateway selection and tracking area list management. Serving GW 224 may terminate the interface towards RAN 201 and route data packets between RAN 201 and core network 220. In addition, serving GW 224 may be a local mobility anchor for inter-eNB handover and may also provide an anchor for inter-3 GPP mobility. Other responsibilities may include lawful interception, charging, and some policy enforcement. The serving GW 224 and the MME 222 may be implemented in one physical node or separate physical nodes.
The PDN GW 226 may terminate the SGi interface towards the Packet Data Network (PDN). The PDN GW 226 may route data packets between the EPC220 and the external PDN, and may perform policy enforcement and charging data collection. The PDN GW 226 may also provide an anchor for mobile devices with non-LTE access. The external PDN may be any type of IP network and IP Multimedia Subsystem (IMS) domain. The PDN GW 226 and the serving GW 224 may be implemented in a single physical node or in separate physical nodes.
The eNB204 (macro eNB and micro eNB) may terminate the air interface protocol and may be the first point of contact for the UE 202. In some embodiments, the eNB204 may implement various logical functions of the RAN 201, including but not limited to RNCs (radio network controller functions) such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management. According to an embodiment, the UE202 may be configured to communicate Orthogonal Frequency Division Multiplexed (OFDM) communication signals with the eNB204 via a multicarrier communication channel in accordance with an OFDMA communication technique. The OFDM signal may include a plurality of orthogonal subcarriers.
S1 interface 215 may be an interface that separates RAN 201 and EPC 220. It can be divided into two parts: S1-U, which may carry traffic data between eNB204 and serving GW 224; and S1-MME, which may be a signaling interface between eNB204 and MME 222. The X2 interface may be an interface between enbs 204. The X2 interface may include two parts, X2-C and X2-U. X2-C may be a control plane interface between eNBs 204, while X2-U may be a user plane interface between eNBs 204.
With cellular networks, LP cell 204b may generally be used to extend coverage to indoor areas where outdoor signals do not reach well, or to increase network capacity in heavily used areas. In particular, it may be desirable to enhance the coverage of a wireless communication system using different sized cells (macro, micro, pico, and femto cells) to improve system performance. The different sized cells may operate on the same frequency band or may operate on different frequency bands, with each cell operating in a different frequency band, or only the different sized cells operating on different frequency bands. As used herein, the term LP eNB refers to an eNB for implementing any suitable relative LP for a smaller cell (smaller than a macro cell), such as a femto cell, pico cell, or micro cell. Femto cell enbs may typically be provided by mobile network operators to their residential or business customers. A femto cell may typically be the size of a residential gateway or smaller and is typically connected to a broadband line. Femto cells can connect to the mobile operator's mobile network and provide additional coverage, typically in the range of 30 to 50 meters. Thus, LP eNB204b may be a femto cell eNB as it is coupled through the PDN GW 226. Similarly, a picocell may be a wireless communication system that generally covers a small area, such as indoors (offices, malls, train stations, etc.), or more recently, within a cabin. A picocell eNB may typically connect through its Base Station Controller (BSC) functionality to another eNB, such as a macro eNB, via an X2 link. Thus, the LP eNB may be implemented with a picocell eNB as it may be coupled to a macro eNB204a via an X2 interface. The pico eNB or other LP eNB204b may incorporate some or all of the functionality of the macro eNB LP eNB204 a. In some cases, this may be referred to as an access point base station or an enterprise femtocell.
In some embodiments, the UE202 may communicate with an Access Point (AP)204 c. AP 204c may communicate with UE202 using only unlicensed spectrum (e.g., WiFi frequency bands). The AP 204c may communicate with the macro eNB204A (or LP eNB204B) over an Xw interface. In some embodiments, the AP 204c may communicate with the UE202 independently of communication between the UE202 and the macro eNB 204A. In other embodiments, the AP 204c may be controlled by the macro eNB204A and use LWA as described in more detail below.
Communications over an LTE network may be divided into 10ms frames, each of which may contain 10 1ms subframes. Each subframe of a frame may in turn contain two 0.5ms slots. Each subframe may be used for Uplink (UL) communication from the UE to the eNB or Downlink (DL) communication from the eNB to the UE. In one embodiment, the eNB may allocate a greater number of DL communications than UL communications in a particular frame. The eNB may schedule various frequency bands (f)1And f2) Or (c) is transmitted. The resource allocation in a subframe used in one frequency band may be different from the resource allocation in another frequency band. Each slot of a subframe may contain 6-7 OFDM symbols, depending on the system used. In one embodiment, a subframe may contain 12 subcarriers. The downlink resource grid may be used for downlink transmissions from the eNB to the UE, while the uplink resource grid may be used for uplink transmissions from the UE to the eNB or from the UE to another UE. The resource grid may be a time-frequency grid, which is a physical resource in the downlink in each slot. The smallest time-frequency unit in the resource grid may be denoted as a Resource Element (RE). Each column and each row of the resource grid may correspond to one OFDM symbol and one OFDM subcarrier, respectively. The resource grid may contain Resource Blocks (RBs) describing the mapping of physical channels to resource elements and Physical RBs (PRBs). A PRB may be the smallest resource unit that may be allocated to a UE. The frequency of a resource block may be 180kHz wide and the time may be 1 slot long. In frequency, a resource block may be 12 × 15kHz subcarrier wide or 24 × 7.5kHz subcarrier wide. For most channels and signals, 12 subcarriers may be used per resource block, depending on the system bandwidth. In Frequency Division Duplex (FDD) mode, both uplink and downlink frames can be 10ms and frequency (full duplex) or time (half duplex) separated. In Time Division Duplex (TDD), uplink and downlinkSubframes may be transmitted on the same frequency and multiplexed in the time domain. The duration of the resource grid 400 in the time domain corresponds to one subframe or two resource blocks. Each resource grid may include 12 (subcarriers) × 14 (symbols) ═ 168 resource elements.
Each OFDM symbol may contain a Cyclic Prefix (CP), which may be used to effectively cancel inter-symbol interference (ISI), and a Fast Fourier Transform (FFT) period. The duration of the CP may be determined by the highest degree of delay spread expected. Although distortion from the previous OFDM symbol may exist within the CP, where the CP has sufficient duration, the previous OFDM symbol does not enter the FFT period. Once the FFT period signal is received and digitized, the receiver can ignore the signal in the CP.
There may be several different physical downlink channels, including a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH), that are communicated using such resource blocks. Each subframe may be partitioned into PDCCH and PDSCH. The PDCCH may typically occupy the first two symbols of each subframe and carry information about a transmission format and resource allocation related to a PDSCH channel, etc., as well as H-ARQ information related to an uplink shared channel. The PDSCH may carry user data and higher layer signaling to the UE and occupy the remainder of the subframe. In general, downlink scheduling (allocation of control and shared channel resource blocks to UEs within a cell) may be performed at the eNB based on channel quality information provided from the UEs to the eNB, and then downlink resource allocation information may be transmitted to each UE on a PDCCH used for (allocated to) the respective UE. The PDCCH may contain Downlink Control Information (DCI) in one of a number of formats that instruct the UE how to find and decode data transmitted on the PDSCH in the same subframe from the resource grid. The DCI format may provide details such as the number of resource blocks, resource allocation type, modulation scheme, transport block, redundancy version, coding rate, and the like. Each DCI format may have a Cyclic Redundancy Code (CRC) and be scrambled with a Radio Network Temporary Identifier (RNTI) that identifies the target UE for which the PDSCH is intended. Using UE-specific RNTIs may restrict decoding of DCI formats (and thus the corresponding PDSCHs) to only intended UEs.

At least some of the illustrated components may be used in an eNB or MME, such as UE202 or eNB204 shown in fig. 2, for example.

Embodiments may also be implemented as instructions stored on a computer-readable storage device, which may be read and executed by at least one processor to perform the operations described herein.
Fig. 5 illustrates another block diagram of a communication device 500 according to some embodiments. The communication device 500 may correspond to the UE202 or eNB 204. In alternative embodiments, the communication device 500 may operate as a standalone device or may be connected (e.g., networked) to other communication devices. In a networked deployment, the communication device 500 may operate in the capacity of a server communication device, a client communication device, or both, in a server-client network environment. In an example, the communications device 500 may act as a peer to peer communications device in a peer to peer (P2P) (or other distributed) network environment. The communication device 500 may be a UE, eNB, PC, tablet PC, STB, PDA, mobile phone, smart phone, web appliance, network router, switch or bridge, or any communication device capable of executing instructions (sequential or otherwise) that specify actions to be taken by the communication device. Further, while only a single communication device is shown, the term "communication device" shall also be taken to include any collection of communication devices that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein (e.g., cloud computing, software as a service (SaaS), other computer cluster configurations).
As described herein, an example may include, or may operate on, logic or multiple components, modules, or mechanisms. A module is a tangible entity (e.g., hardware) capable of performing specified operations and may be configured or arranged in a certain manner. In an example, a circuit (e.g., internally or with respect to an external entity such as other circuits) may be arranged as a module in a specified manner. In an example, all or a portion of one or more computer systems (e.g., a stand-alone client or server computer system) or one or more hardware processors may be operated by firmware or software (e.g., instructions, application portions, or applications) as a module that operates to perform specified operations. In an example, the software may reside on a communication device readable medium. In an example, the software, when executed by the underlying hardware of the module, causes the hardware to perform the specified operations.
Thus, the term "module" is understood to encompass a tangible entity, either a physical construct, a permanent configuration (e.g., hardwired), or a temporary configuration (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which modules are temporarily configured (e.g., programmed), each module need not be configured or instantiated at any one time. For example, if the modules include a general purpose processor configured using software, the general purpose processor may be configured at different times as respective different modules. Software may thus configure a hardware processor to, for example, constitute a particular module at one time and to constitute a different module at a different time.
A communication device (e.g., computer system) 500 may include a hardware processor 502 (e.g., a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a hardware processor core, or any combination thereof), a main memory 504 and a static memory 506, some or all of which may communicate with each other via an interconnection link (e.g., bus) 508. The communication device 500 may also include a display unit 510, an alphanumeric input device 512 (e.g., a keyboard), and a User Interface (UI) navigation device 514 (e.g., a mouse). In an example, the display unit 510, the input device 512, and the UI navigation device 514 may be a touch screen display. The communication device 500 may additionally include a storage device (e.g., drive unit) 516, a signal generation device 518 (e.g., a speaker), a network interface device 520, and one or more sensors 521, such as a Global Positioning System (GPS) sensor, compass, accelerometer, or other sensor. The communication device 500 may include an output controller 528, such as a serial (e.g., Universal Serial Bus (USB), parallel, or other wired or wireless (e.g., Infrared (IR), Near Field Communication (NFC), etc.) connection for communicating or controlling one or more peripheral devices (e.g., printer, card reader, etc.).
The storage device 516 may include a communication device readable medium 522 on which is stored one or more data structures or sets of instructions 524 (e.g., software) embodying or used by any one or more of the techniques or functions described herein. The instructions 524 may also reside, completely or at least partially, within the main memory 504, within static memory 506, or within the hardware processor 502 during execution thereof by the communication device 500. In an example, one or any combination of the hardware processor 502, the main memory 504, the static memory 506, or the storage device 516 may constitute communication device readable media.
While the communication device-readable medium 522 is shown to be a single medium, the term "communication device-readable medium" can include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 524.
The term "communication device-readable medium" may include any medium that is capable of storing, encoding or carrying instructions for execution by communication device 500 and that cause communication device 500 to perform any one or more of the techniques of this disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting examples of communication device readable media may include solid state memory and optical and magnetic media. Specific examples of the communication device readable medium may include: non-volatile memories such as semiconductor memory devices (e.g., electrically programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; random Access Memory (RAM); and CD-ROM and DVD-ROM disks. In some examples, the communication device readable medium may include a non-transitory communication device readable medium. In some examples, the communication device readable medium may include a communication device readable medium of a non-transitory propagating signal.
The instructions 524 may further be transmitted or received using a transmission medium via the network interface device 520 and over a communication network 526 using any one of a number of transmission protocols (e.g., frame relay, Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a Local Area Network (LAN), a Wide Area Network (WAN), a packet data network (e.g., the internet), a mobile telephone network (e.g., a cellular network), a Plain Old Telephone (POTS) network, and a wireless data network (e.g., referred to as a "POTS") networkOf the Institute of Electrical and Electronics Engineers (IEEE)802.11 family of standards, known asIEEE 802.16 family of standards), IEEE 802.15.4 family of standards, Long Term Evolution (LTE) family of standards, Universal Mobile Telecommunications System (UMTS) family of standards, peer-to-peer (P2P) networks, and the like. In an example, the network interface device 520 may include one or more physical jacks (e.g., ethernet, coaxial, or phone jacks) or one or more antennas connected to the communication network 526. In an example, the network interface device 520 may include multiple wireless antennas to communicate using at least one of single-input multiple-output (SIMO), MIMO, or multiple-input single-output (MISO) techniques. In some examples, the network interface device 520 may wirelessly communicate using multi-user MIMO techniques. The term "transmission medium" shall be taken to include any intangible medium that is capable of storing, encoding, or carrying instructions for execution by the communication device 500, and includes digital or analog communication signals or other intangible medium to facilitate communication of such software.

At block 730, the UE202 applies rate matching to the encoded bit sequence (d)(1) 0…d(1) D-1) To obtain a rate-matched bit sequence (e)0…eE-1)。
For each subframe, HARQ-ACK bits are received from a higher layer. HARQ-ACK consists of 1 bit of information, i.e., b0Or consist of 2 bits of information, i.e. b0b1Wherein b is0ACK/NACK bit corresponding to codeword 0 and b1Corresponding to the ACK/NACK bit of codeword 1. Each positive Acknowledgement (ACK) is decoded as a binary '1' and each Negative Acknowledgement (NACK) is decoded as a binary '0'. For the case where xPUCCH format 3 is configured or scheduled, the HARQ-ACK feedback includes a concatenation of HARQ-ACK bits that the UE needs to feedback for the downlink subframe. For cells configured with transmission mode 1 or 2 (i.e., single codeword transmission mode), 1 bit of HARQ-ACK information akFor that cell. For cells configured with other transmission modes, 2-bit HARQ-ACK information (i.e., a)k、ak+1) Is used for these cells, wherein akHARQ-ACK bit and a corresponding to codeword 0k+1HARQ-ACK bits corresponding to codeword 1.
