A terminal device may be a device that provides voice/data connectivity to users, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, examples of some terminals can be: mobile phone (mobile phone), tablet computer (pad), computer with wireless transceiver function (such as notebook computer, palmtop computer, etc.), mobile internet device (mobile internet device, MID), virtual reality (virtual reality, VR) equipment, augmented reality (augmented reality, AR) equipment, wireless terminals in industrial control (industrial control), wireless terminals in self driving (self driving), wireless in remote medical (remote medical) Terminals, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home, cellular phones, cordless Telephones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, or connected Other processing devices to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in the 5G network or terminal devices in the future evolution of the public land mobile network (PLMN), etc.

Among them, wearable devices can also be called wearable smart devices, which is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only a hardware device, but also achieve powerful functions through software support, data interaction, and cloud interaction. Generalized wearable smart devices include full-featured, large-sized, complete or partial functions without relying on smart phones, such as smart watches or smart glasses, etc., and only focus on a certain type of application functions, and need to cooperate with other devices such as smart phones Use, such as various smart bracelets and smart jewelry for physical sign monitoring.

In addition, the terminal device may also be a terminal device in an Internet of Things (Internet of things, IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, so as to realize the intelligent network of human-machine interconnection and object interconnection. IoT technology can achieve massive connections, deep coverage, and terminal power saving through, for example, narrow band (NB) technology.

In addition, terminal equipment can also include sensors such as smart printers, train detectors, and gas stations. The main functions include collecting data (part of terminal equipment), receiving control information and downlink data from network equipment, sending electromagnetic waves, and transmitting uplink data to network equipment. .

In this embodiment of the present application, the network device may be any device with a wireless transceiver function. Network equipment includes but not limited to: evolved Node B (evolved Node B, eNB), radio network controller (radio network controller, RNC), Node B (Node B, NB), base station controller (base station controller, BSC) , base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (baseband unit, BBU), wireless fidelity (wireless fidelity, WiFi) system Access point (access point, AP), wireless relay node, wireless backhaul node, transmission point (transmission point, TP) or transmission and reception point (transmission and reception point, TRP), etc., can also be 5G, such as NR , a gNB in the system, or, a transmission point (TRP or TP), one or a group (including multiple antenna panels) antenna panels of a base station in a 5G system, or, it can also be a network node that constitutes a gNB or a transmission point, Such as a baseband unit (BBU), or a distributed unit (distributed unit, DU), etc.

In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU can be responsible for processing non-real-time protocols and services, for example, it can implement the radio resource control (radio resource control, RRC) layer, service data adaptive protocol (service data) Adaptation protocol (SDAP) layer and/or packet data convergence protocol (packet data convergence protocol, PDCP) layer functions. DU can be responsible for handling physical layer protocols and real-time services. For example, functions of a radio link control (radio link control, RLC) layer, a media access control (media access control, MAC) layer, and a physical (physical, PHY) layer may be implemented. A DU can be connected to only one CU or to multiple CUs, and a CU can be connected to multiple DUs, and CUs and DUs can communicate through the F1 interface. The AAU can realize some physical layer processing functions, radio frequency processing and related functions of active antennas. Because the information of the RRC layer will eventually be submitted to the PHY layer to become the information of the PHY layer, or converted from the information of the PHY layer, therefore, under this architecture, high-level signaling, such as RRC layer signaling, also It can be considered as sent by the DU, or sent by the DU+AAU.

It can be understood that the network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU can be divided into network devices in an access network (radio access network, RAN), and the CU can also be divided into network devices in a core network (core network, CN), which is not limited in this application.

The network device provides services for the cell, and the terminal device communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network device. The cell may belong to a macro base station (for example, a macro eNB or a macro gNB, etc.) , can also belong to the base station corresponding to a small cell, where the small cell can include: a metro cell, a micro cell, a pico cell, a femto cell, etc. , these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

It should be understood that the present application does not limit the specific forms of the network device and the terminal device.

In a wireless communication system, if there is only one carrier in each cell under the base station, the terminal can only transmit and receive data in one cell (one carrier) at a time, and this scenario is a single-carrier transmission scenario. The aforementioned carrier may be a component carrier (component carrier, CC), or may occupy part of the bandwidth of the wireless communication system. In the long term evolution system LTE, the maximum bandwidth of the carrier is 20MHz.

In the upgraded version of the LTE (LTE-Advanced, LTE-A) system, the Carrier Aggregation (CA) technology is introduced, which can aggregate 2 to 5 LTE component carriers together for data transmission and reception, achieving a maximum of 100MHz Transmission bandwidth, effectively improving the uplink and downlink data transmission rate. Specifically, the terminal may decide according to its own capability that at most several carriers can be aggregated for uplink and downlink data transmission at the same time, or the network configures a carrier aggregation function for the terminal. The above scenario is a multi-carrier (or carrier aggregation) transmission scenario.

The downlink and uplink non-coherent transmission based on multiple sending and receiving points TRP is introduced in the NR system. Among them, the backhaul network (backhaul) connection between TRPs can be ideal or non-ideal. Under the ideal backhaul network, TRPs can quickly and dynamically exchange information. Large TRPs can only exchange information quasi-statically (with a long interaction time).

In downlink non-coherent transmission, multiple TRPs can use different control channels to independently schedule multiple PDSCH transmissions of a terminal, or use the same control channel to schedule the transmission of different TRPs, where the data of different TRPs use different transmission layers. The latter can only be used in the case of an ideal backhaul network.

In uplink non-coherent transmission, different TRPs can also independently schedule the PUSCH transmission of the same terminal. Different PUSCH transmissions can be configured with independent transmission parameters, such as beam, precoding matrix, number of layers, etc. The scheduled PUSCH transmissions can be transmitted in the same slot or in different slots. If the terminal is scheduled to transmit two PUSCHs simultaneously in the same time slot, it needs to determine how to perform the transmission according to its own capabilities.

FIG. 1 is a schematic diagram of uplink transmission provided by an embodiment of the present application. FIG. 2 is a schematic diagram of another uplink transmission provided by the embodiment of the present application. If the terminal is configured with multiple antenna panels and supports simultaneous transmission of PUSCH on multiple antenna panels, the two PUSCHs can be transmitted at the same time, and the PUSCHs transmitted on different antenna panels are aligned with the corresponding TRP for analog shaping, thereby passing The space domain distinguishes different PUSCHs to provide uplink spectrum efficiency, as shown in Figure 1. If the terminal has only a single antenna panel, or does not support simultaneous transmission of multiple antenna panels, the PUSCH can only be transmitted on one antenna panel. Similar to the downlink, the PUSCH transmitted by different TRPs can be scheduled based on multiple downlink control information (Downlink Control Information, DCI), and these DCIs can be carried by different control resource sets (Control Resource Set, CORESET). Specifically, multiple CORESET groups are configured on the network side, and each TRP is scheduled using a CORESET in its own CORESET group, that is, different TRPs can be distinguished by the CORESET group. For example, a network device may configure a CORESET group index for each CORESET, and different indexes correspond to different TRPs. Similarly, PUSCHs transmitted to different TRPs can be scheduled based on a single DCI. At this time, the DCI needs to indicate the beams and demodulation reference signal (Demodulation Reference Signal, DMRS) ports used by the PUSCHs transmitted to different TRPs, as shown in Figure 2 Show.

A similar method can also be used for PUCCH transmission. FIG. 3 is a schematic diagram of another uplink transmission provided by the embodiment of the present application. As shown in Figure 3, the terminal can configure two PUCCHs to be transmitted on different antenna panels at the same time. The beams used by different antenna panels are different, and the respective space-related information is notified to the terminal.

Currently, the transmit power of PUSCH can be calculated by the following formula:

Among them, P _CMAX,f,c (i) is the maximum transmission power supported by the terminal on the carrier f of the serving cell c; i is the index of a PUSCH transmission; j is the open-loop power control parameter index (including the target power P _{O_PUSCH,b ,f,c} (j) and path loss factor α _b,f,c (j));

is the number _of physical _resource blocks PRB occupied by the terminal to transmit _PUSCH on the carrier f of the serving cell c; ), is also an open-loop power control parameter; Δ _TF,b,f,c (i) is an adjustment value related to the coded modulation mode MCS; f _b,f,c (i,l) is a closed-loop power control adjustment factor, where l is the closed-loop power control process. Wherein, the terminal determines the closed-loop power adjustment factor according to the transmission power control (Transmit Power Control, TPC) command sent by the network side. The TPC command can be carried by the DCI used to schedule the PUSCH in the terminal search space, or can be carried by the DCI in the public search space. It is carried by DCI format 2_2 used to carry group TPC commands.

In the NR system, the terminal determines the transmission beam of the scheduled PUSCH based on the SRS resource indicator (SRI) in the DCI, and also determines the power control parameters used by the PUSCH based on the SRI. Specifically, the network side pre-configures multiple SRI-PUSCH-PowerControl parameter fields through RRC signaling, each parameter field corresponds to an SRI value, and the parameter field contains a set of PUSCH power control parameter configurations corresponding to the SRI value (for example j,qd,l). When the values indicated by the SRI are different, the power control parameter configuration in the corresponding parameter field (SRI-PUSCH-PowerControl) is used to determine the transmit power of the currently scheduled PUSCH.

At present, the transmission power of SRS can be calculated by the following formula:

Among them, P _CMAX,f,c (i) is the maximum transmission power supported by the terminal on the carrier f of the serving cell c; i is the index of an SRS transmission, and q _s is the open-loop power control parameter index (including the target power P _{O_SRS, b,f,c} (q _s ) and path loss factor α _SRS,b,f,c (q _s )); M _SRS,b,f,c (i) is the SRS occupied by the terminal on the carrier f of the serving cell c The number of PRBs; q _d is the index of the reference signal used for path loss measurement, used to obtain the path loss value PL _b,f,c (q _d ), which is also an open-loop power control parameter; h _{b,f, c} (i, l) is the closed-loop power control adjustment factor, where l is the closed-loop power control process. Wherein, q _s and q _d are included in the configuration parameters of the SRS resource set, and are configured to the terminal through high-layer signaling. If high layer signaling configures the SRS and PUSCH to use the same power control process, then h _{b, f, c} (i, l) = f _{b, f, c} (i, l). If high-layer signaling configures SRS to adopt an independent power control process, the network side indicates the TPC command of each terminal's own SRS through DCI format 2_3 in the common search space, and the terminal determines the closed-loop power adjustment factor according to its TPC command. The closed-loop power The adjustment factor has nothing to do with the PUSCH closed-loop power adjustment factor.

If the terminal device is configured with multiple antenna panels (panels), and supports simultaneous transmission of PUSCH (or PUCCH) on multiple antenna panels, the base station can simultaneously schedule multiple PUSCH (or PUCCH), and the PUSCH transmitted on different antenna panels (or PUCCH) is aligned with the corresponding TRP to perform analog shaping, so as to distinguish different PUSCHs (or PUCCH) through the space domain. Different antenna panels can perform power control independently, and the transmit power of the terminal needs to be allocated to different antenna panels for signal transmission.

When the terminal transmits uplink signals through multiple antenna panels, the transmit power on each antenna panel may be determined independently. For example, the maximum transmit power and power control parameters may be different on different antenna panels. If the sum of the maximum transmit power of multiple antenna panels on a carrier exceeds the maximum transmit power supported by the terminal on this carrier, the sum of the actual transmit power of multiple antenna panels may also exceed the maximum transmit power supported by the terminal on this carrier power. At this time, the terminal needs to reduce the transmit power on multiple antenna panels to ensure that the total actual transmit power will not exceed the maximum allowable transmit power. When the sum of the transmit power on multiple antenna panels exceeds the maximum transmit power that the terminal can support, how to allocate appropriate transmit power to each antenna panel of the terminal is an urgent problem to be solved at present.

In view of the above problems, the embodiment of the present application shows a power allocation method, which is mainly used for the uplink transmission of the terminal. The main idea of the invention is as follows:

For single-carrier scheduling, such as the scheduling of the first carrier, the terminal first determines the allowable transmission power of the first carrier, and reasonably allocates the transmission power between different antenna panels of the first carrier according to the order of signal priority to ensure that the transmission power of the first carrier On the premise that the total transmit power of multiple antenna panels does not exceed the allowable transmit power of the first carrier, the transmission of important information is given priority.

For multi-carrier scheduling, uplink transmission of multi-carrier and multi-antenna panels is supported. The terminal can first perform multi-carrier power allocation, determine the transmission power allowed by the first carrier, and then perform power allocation for multiple antenna panels of the first carrier; or, The terminal can first perform power allocation on multiple antenna panels of the first carrier, and then perform power allocation on multiple carriers to determine the actual transmission power of the first carrier, and finally perform power allocation on multiple antenna panels on the first carrier to ensure the final The total transmission power of the multiple antenna panels of the first carrier after one power allocation does not exceed the actual transmission power of the first carrier.

Based on the above solution, power allocation for multiple antenna panels in a single-carrier or multi-carrier scenario can be realized, the transmission of important information is guaranteed first, and the uplink transmission performance of the terminal is further improved.

It should be pointed out that the priority order of the signals can be understood as the priority order of the importance of the signals, and can also be understood as the order of the mandatory signals and optional signals in the protocol.

The technical solutions provided by the embodiments of the present application will be described in detail below through specific embodiments.

It should be noted that the technical solutions provided by the embodiments of this application may include part or all of the following content, the following specific embodiments may be combined with each other, and the same or similar concepts or processes may be used in some embodiments No longer.

FIG. 4 is a first flowchart of a power allocation method provided by an embodiment of the present application. As shown in FIG. 4, the power allocation method of this embodiment can be used in a single carrier (single CC) scheduling scenario, and the method includes:

Step 101, the terminal device determines the first transmit power allowed on the first carrier.

In this step, it is assumed that the first transmit power is the maximum transmit power supported by the terminal device on the first carrier.

The maximum transmit power may be determined by the terminal device and reported to the network device, or determined by the network device and configured to the terminal device. For example, the network device may configure the transmit power of the terminal device on the first carrier through RRC.

Step 102: If the total transmission power of the terminal device's signals on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device prioritizes the first transmission power and the signals on the multiple antenna panels from high to high. Low power allocation is performed on the signals on the multiple antenna panels in turn until the total transmission power of the signals on the multiple antenna panels is equal to the first transmission power (that is, the total transmission power of the signals on the multiple antenna panels after power allocation is equal to the first transmission power) A transmit power, or the goal of power allocation is to make the total transmit power of signals on multiple antenna panels not exceed the first transmit power).

In an optional embodiment of this embodiment, if the total transmission power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device may The priority order of the signals is from high to low to perform power allocation on the signals on multiple antenna panels. Wherein, the priority order of the signal includes at least one of the first priority order, the second priority order, and the third priority order, and details of the three priority orders may refer to the following embodiments.

In an optional embodiment of this embodiment, the terminal device performs power allocation on the signals on the multiple antenna panels of the first carrier in sequence from high to low according to the first transmit power and the first priority until the first carrier's The total transmission power of the signals on the multiple antenna panels is equal to the first transmission power.

As an example, before the terminal device allocates power to the signals on the multiple antenna panels of the first carrier in descending order according to the first transmit power and the first priority order, the terminal device may receive multiple signals configured by the network device. There are four reference signal resource sets, and different reference signal resource sets use different antenna panels to transmit or receive reference signals. For example, the network device can configure multiple Channel State Information Reference Signal (CSI-RS) resource sets, and different sets are received on different antenna panels; or, the network device can be configured with multiple reference signal sets, different The set is sent on different antenna panels; or, the network device can indicate multiple physical cell IDs (Physical Cell ID, PCI), and the synchronization signal block (Synchronization Signal Block, SSB) associated with each PCI as a set, thus different collections are received on different antenna panels. At this time, each uplink signal may be associated with a reference signal set, so that the transmitting or receiving antenna panel of the associated reference signal set is used as the transmitting antenna panel of the uplink signal. Alternatively, the network device may configure an antenna panel identification (panel ID) for each uplink signal, and determine the antenna panel for transmitting the uplink signal according to the panel ID. To sum up, in the embodiment of the present application, the signals on different antenna panels may be signals associated with different reference signal resource sets, or signals associated with different panel IDs. For example, the signals on the first antenna panel may be signals associated with the first reference signal resource set, and the signals on the second antenna panel may be signals associated with the second reference signal resource set.

Optionally, the total transmission power of signals on multiple antenna panels can be calculated on the minimum time-domain unit of signal transmission, Orthogonal Frequency Division Multiplexing symbol (OFDM symbol), and the terminal equipment on different antenna panels The sum of linear values of transmit power for sending uplink signals. The transmission power of the uplink signal may be the transmission power of the uplink signal to be transmitted, that is, the expected transmission power of the uplink signal to be transmitted calculated by the terminal device according to the above power control parameters.

In an optional implementation manner, the terminal device allocates power to the signals on the multiple antenna panels sequentially according to the priority order of the signals on the multiple antenna panels from high to low, that is, according to the pre-calculated The transmission power of the signal on the antenna panel, the power is allocated to the signal with the highest priority first, and then the remaining power is allocated to the signal with the second highest priority, and so on, until the sum of the transmission power of the signals on multiple antenna panels reaches the first Once the power is sent, the power allocation is complete. That is to say, if the total transmit power of multiple antenna panels is greater than the first transmit power, the first transmit power can only be assigned to the signal on the antenna panel with the highest priority, and the signals on the antenna panel with lower priority can only be distributed to the signal on the antenna panel with the highest priority. Less power can be allocated, that is, signals on antenna panels with lower priority need to be transmitted with reduced power, so that the sum of actual transmit powers of signals on multiple antenna panels of the first carrier does not exceed the first transmit power.

Exemplarily, taking the two antenna panels of the carrier A as an example, assuming that the expected transmit powers of the two antenna panels of the carrier A are P ₁ and P ₂ respectively, the maximum transmit power supported by the terminal device on the carrier A is P _max . In the case of P ₁ +P ₂ >P _max (assuming that the power is a linear value), the terminal device will judge the priority of the uplink signals sent on the two antenna panels, and assign the power to the one with higher priority Signal. Assuming that the priority of the signal on antenna panel 1 is higher than that of the signal on antenna panel 2, in one case, if P _max >P ₁ , the power P ₁ is first distributed to the signal on antenna panel 1, and then the remaining P The power of _max -P ₁ is distributed to the signal on the antenna panel 2, then the signal on the antenna panel 2 is reduced by the power of (P ₁ +P ₂ -P _max ); in another case, if P ₁ >P _max , the power P _max is all allocated to the signal on the antenna panel 1, and since the signal on the antenna panel 2 is not allocated power, the signal on the antenna panel 2 is not transmitted. It should be noted that, in the first case above, if the remaining P _max -P ₁ is smaller than the preset threshold value, the signal on the antenna panel 2 may not be sent.

Exemplarily, taking the three antenna panels of carrier A as an example, assuming that the expected transmit powers of the three antenna panels of carrier A are P ₁ , P ₂ and P ₃ respectively, the maximum transmit power supported by terminal equipment on carrier A is P _max . In the case of P ₁ +P ₂ +P ₃ >P _max (assuming that the power is a linear value), the terminal device will judge the priority of the uplink signals sent on the three antenna panels, and first allocate the power to the highest priority signal, and then allocate the remaining power to the signal with the second highest priority. Suppose the order of signal priority is: signal on antenna panel 1 > signal on antenna panel 2 > signal on antenna panel 3, in one case, if P _max >P ₁ , the power P ₁ is distributed to the antenna first signal on panel 1, and distribute the remaining P _max -P ₁ to the signal on antenna panel 2 first. If P _max -P ₁ >P ₂ , then distribute the power P ₂ to the signal on the antenna panel 2 first, and finally distribute the remaining power of P _max -P ₁ -P ₂ to the signal on the antenna panel 3 (if P _max -P ₁ -P ₂ is less than the preset threshold value, then the signal on the antenna panel 3 will not be transmitted); or, if P _max -P ₁ <P ₂ , all the power P _max -P ₁ will be assigned to the antenna For the signal on the panel 2, since the signal on the antenna panel 3 is not allocated power, the signal on the antenna panel 3 is not transmitted. In another case, if P _max < P ₁ , all the power P _max is allocated to the signal on antenna panel 1, and since the signals on antenna panels 2 and 3 are not allocated power, antenna panels 2 and 3 are not sent on the signal.

For the power allocation of more than three antenna panels of the carrier A, its implementation principle is similar to the above example, and will not be repeated here.

In an optional implementation manner, if the total transmission power of the terminal device's signals on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device may The first priority order of the signals performs power allocation to the signals on the multiple antenna panels in sequence from high to low. Among them, the first priority order from high to low is:

(1) Physical Random Access Channel PRACH;

(2) A physical uplink shared channel PUSCH or a physical uplink control channel PUCCH with a priority index of 1;

(3) PUSCH or PUCCH with a priority index of 0;

(3) Aperiodic sounding reference signal SRS;

(4) Periodic SRS or semi-continuous SRS.

It should be noted that the PUSCH or PUCCH with a priority index of 1 has a higher priority than the PUSCH or PUCCH with a priority index of 0. Optionally, the value of the priority index is not limited to 0 and 1, and a value greater than 1 may also be used. Similarly, an uplink signal with a higher value of the priority index has a higher priority order.

Optionally, if the priority indexes of the PUSCH or PUCCH are the same, the terminal device may sort the PUSCH or PUCCH with the same priority index from high to low according to the first transmit power and the second priority order of signals on multiple antenna panels. for power distribution. Among them, the second priority order from high to low is:

(1) PUCCH carrying hybrid automatic repeat request confirmation HARQ-ACK information, or PUCCH carrying scheduling request SR, or PUCCH carrying Link Recovery Request (LRR), or carrying HARQ-ACK information PUSCH;

(2) PUCCH or PUSCH carrying channel state information CSI;

(3) PUSCH without HARQ-ACK information and CSI, or PUSCH of Type 2 random access procedure.

In an optional implementation manner, if the total transmit power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmit power, and the signals on two of the multiple antenna panels are within The priority of the first priority order and/or the second priority order is the same, and the terminal device can reduce the transmission power of the signals on the two antenna panels in the same proportion, so that the total transmission power of the signals on the multiple antenna panels is not the same. exceeds the first transmit power.

Exemplarily, taking the two antenna panels of carrier A as an example, it is assumed that the second priorities of the signals on the two antenna panels of carrier A are the same, for example, both antenna panels transmit PUCCH carrying HARQ-ACK, or both To send PUSCH that does not carry CSI, if the total transmit power of the signals on the two antenna panels of carrier A is greater than the first allowable transmit power on carrier A, the terminal device can use the same ratio to reduce the transmission of signals on the two antenna panels power, so that the total transmit power of the signals on the multiple antenna panels of the carrier A is equal to the first transmit power. Specifically, it is assumed that the expected transmit powers of the two antenna panels are P ₁ and P ₂ respectively, and the maximum transmit power supported by the terminal device on the carrier A is P _max . In the case of P ₁ +P ₂ >P _max and the signals on the two antenna panels have the same priority, the power obtained by the terminal equipment after reducing the power on the two antenna panels in equal proportion is: P ₁ *P _max /( P ₁ +P ₂ ) and P ₂ *P _max /(P ₁ +P ₂ ).

In an optional implementation manner, if the total transmit power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmit power, and the signals on two of the multiple antenna panels are within The priority of the first priority order and/or the second priority order is the same, and the terminal device can perform power allocation on the signals on the two antenna panels according to the third priority order, so as to ensure the total power of the signals on the multiple antenna panels. The transmission power does not exceed the first transmission power.

Among them, the third priority order includes at least one of the following:

(1) The priority of the PUSCH scheduled by the downlink control information DCI is higher than that of the PUSCH scheduled by the radio resource control RRC signaling;

(2) The priority of PUSCH scheduled by DCI format format 0_2 is higher than that of PUSCH scheduled by DCI format 0_1;

(3) The priority of the PUSCH scheduled by the DCI scrambled by the cell wireless network temporary identifier MCS-C-RNTI scrambled in the modulation and coding mode is higher than that of the PUSCH scheduled by the DCI scrambled by the C-RNTI;

(4) The priority of non-repeatedly transmitted signals is higher than that of repeatedly transmitted signals;

(5) The priority of the signal whose identification panel ID of the associated antenna panel is 0 is higher than that of the signal whose associated panel ID is 1;

(6) The signal associated with the first reference signal resource set has a higher priority than the signal associated with the second reference signal resource set;

(7) The priority of the signal whose associated control resource set CORESET group index is 0 is higher than the signal whose associated CORESET group index is 1;

(8) The signal sent at the first moment has a higher priority than the signal sent at the second moment, and the first moment is earlier than the second moment. That is, signals that start sending earlier have higher priority.

(9) The signal scheduled at the third time has a higher priority than the signal scheduled at the fourth time; wherein, the third time is earlier than the fourth time, or the third time is later than the fourth time. That is, a signal scheduled earlier has a higher priority, or a signal scheduled later has a higher priority.

(10) Signals with low transmission power have a higher priority than signals with high transmission power.

It should be noted that the above signal is an uplink signal.

It should be noted that the first moment and the second moment have an associated relationship (that is, the relationship of chronological order), the third moment and the fourth moment have an associated relationship, and the first moment has no associated relationship with the third moment or the fourth moment. The second moment is not related to the third or fourth moment.

It should be noted that the above-mentioned third priority order can be used in combination, that is, when the priority order of two signals is the same according to a certain rule in the third priority order, another rule in the third priority order can be combined Continue to judge until the priority of these two signals is determined.

In an optional implementation manner, if the total transmission power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device may send signals according to the first transmission power and the third priority order Power allocation is performed on the signals on the multiple antenna panels to ensure that the total transmission power of the signals on the multiple antenna panels does not exceed the first transmission power.

Exemplarily, taking the two antenna panels of carrier A as an example, assuming that the signals on the two antenna panels of carrier A are the same, for example, both antenna panels transmit PUSCH, if the total of the signals of the two antenna panels of carrier A The transmit power is greater than the first transmit power allowed on carrier A, and the terminal device may perform power allocation on the two antenna panels according to the third priority order. Assuming that the PUSCH sent by antenna panel 1 is a DCI-scheduled PUSCH, and the PUSCH sent by antenna panel 2 is a RRC signaling-scheduled PUSCH, the terminal device can first allocate power to antenna panel 1 according to (1) in the third priority order PUSCH on the antenna panel 2, and then distribute the remaining power to the PUSCH on the antenna panel 2.

Exemplarily, taking the three antenna panels of carrier A as an example, it is assumed that the signals on the three antenna panels of carrier A are the same. The transmit power is greater than the first allowable transmit power P _max on the carrier A, and the terminal device may perform power allocation on the three antenna panels according to the third priority order. Assuming that the signal transmission power on antenna panel 1, antenna panel 2, and antenna panel 3 are P ₁ , P ₂ , and P ₃ respectively, and the values of these three powers are P ₁ <P ₂ <P ₃ , the terminal device can (10) of the three priority order, the power P ₁ is allocated to the signal on the antenna panel 1 first, and then the remaining power P _max -P ₁ is preferentially allocated to the signal on the antenna panel 2, and finally the remaining P _max - The power of P ₁ -P ₂ is distributed to the signal on the antenna panel 3 (if P _max -P ₁ -P ₂ is smaller than the preset threshold value, the signal on the antenna panel 3 is not transmitted).

In an optional implementation manner, if the total transmission power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmission power, and the signals on two antenna panels among the multiple antenna panels have priority The levels are the same, the terminal device may reduce the transmit power of the signals on the two antenna panels in the same proportion, so that the sum of the actual transmit powers of the signals on the multiple antenna panels is equal to the first transmit power. Wherein, the signal priority being the same includes that at least one of the first priority order, the second priority order and the third priority order of the signals is the same.

Optionally, on the basis of the foregoing embodiments, if the transmission power of a signal on any antenna panel after power allocation or reduced transmission power is less than a threshold value, the terminal device does not perform signal transmission on the antenna panel. Exemplarily, for example, if after the power is allocated to the signal on the antenna panel with a higher priority, the remaining power that can be allocated to the signal on the antenna panel with a lower priority is lower than the threshold value, the terminal device does not send The signal on the antenna panel with lower priority. For another example, after the terminal device reduces the transmit power of signals on multiple antenna panels in the same proportion, if the actual transmit power on a certain antenna panel is less than the threshold value, the terminal device does not transmit the signal on the antenna panel.

Optionally, the threshold value may be an absolute value of the transmit power, such as X dBm, where X is a positive number.

Optionally, the threshold value may be a ratio of the transmit power to the maximum transmit power of the antenna panel, that is, a value between 0 and 1.

Optionally, the threshold value may be a ratio of the transmit power to the maximum transmit power supported on the first carrier, that is, a value between 0 and 1.

Optionally, the threshold value is a network configuration or a predefined threshold value. If the threshold value is pre-configured by the network device, the network device sends the threshold value to the terminal device. If the threshold value is predefined by the terminal device, the terminal device reports the UE capability to the network device.

In the power allocation method shown in this embodiment, the terminal device first determines the first transmit power allowed on the first carrier, and if the total transmit power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmit power, The terminal device allocates power to the signals on the multiple antenna panels in sequence from high to low according to the first transmission power and the priority order of the signals on the multiple antenna panels until the signals on the multiple antenna panels of the first carrier The total transmit power is equal to the first transmit power, which ensures priority transmission of important information on multiple antenna panels and improves the uplink transmission performance of the terminal.

FIG. 5 is a second flowchart of the power allocation method provided by the embodiment of the present application. As shown in FIG. 5, the power allocation method of this embodiment can be used in a carrier aggregation scenario, and the method includes:

Step 201, the terminal device determines the second transmit power on the first carrier.

In this step, the second transmission power is the expected transmission power of the terminal device on the first carrier.

Optionally, the second transmission power is a sum of expected transmission powers of signals on multiple antenna panels of the first carrier. Specifically, the terminal device can calculate the expected transmission power of the uplink signal to be transmitted on the first carrier according to the above power control parameters, so as to determine the second transmission power. For details, refer to the above embodiments, and details will not be repeated here.

Optionally, the second transmit power is the maximum transmit power supported on the first carrier.

Optionally, the second transmission power is a smaller value between the sum of expected transmission powers of signals on multiple antenna panels of the first carrier and the maximum transmission power supported on the first carrier.

Step 202, the terminal device performs power allocation on multiple carriers, and determines first transmit power of the terminal device on the first carrier.

It should be noted that, before performing power allocation on the multiple carriers, the terminal equipment needs to determine the expected transmit power (ie, the second transmit power) on the first carrier among the multiple carriers, and also need to determine Expected transmit power on each carrier other than the first. For the manner of determining the expected transmission power on other carriers, refer to the manner of determining the expected transmission power on the first carrier.

In this embodiment, the first transmission power is the actual transmission power of the terminal device on the first carrier.

In an optional implementation manner, if the sum of the expected transmission powers of signals of the terminal device on multiple carriers (for the first carrier, that is, the second transmission power) is greater than the maximum transmission power that the terminal device can support on all carriers Power, the terminal device can allocate power to the signals on multiple carriers in order according to the maximum transmit power that can be supported on all carriers and the priority order of signals on multiple carriers from high to low, so that the signals on multiple carriers The sum of the actual transmit power of the terminal device does not exceed the maximum transmit power that the terminal device can support on all carriers. That is to say, the goal of power allocation is to make the total transmission power of signals on multiple carriers not exceed the maximum transmission power.

Optionally, the priority order of the signal includes at least one of the above first priority order, second priority order, and third priority order.

That is to say, based on the expected transmission power of each carrier, the terminal device allocates power to the signal on the carrier with the highest priority first, then distributes the remaining power to the signal on the carrier with the second highest priority, and so on, until When the sum of the transmit powers of signals on multiple carriers reaches the maximum transmit power that the terminal device can support on all carriers, the power allocation is completed. At this time, the signal on the carrier with lower priority needs to be transmitted with reduced transmission power.

In an optional implementation manner, the terminal device sequentially evaluates the signals on multiple carriers according to the maximum transmit power that can be supported on all carriers and the priority order of signals on all antenna panels of each carrier from high to low for power distribution. Specifically, the terminal device sorts the signals on all the antenna panels on multiple carriers according to the order of priority, and preferentially allocates power to the signals with higher priority among them (whether they are signals of the same carrier or not).

Exemplarily, the terminal device is configured with carrier A and carrier B, where antenna panel 1 and antenna panel 2 on carrier A transmit signal 1 and signal 2 respectively, and antenna panel 1 and antenna panel 2 on carrier B transmit signal 3 and signal 2 respectively. Signal 4, and the priority order of the signals is {signal 2, signal 4, signal 3, signal 1}, then the terminal device will perform power allocation on these signals in order according to this priority order, that is, the power allocation is in units of signals.

In an optional implementation, the terminal device determines the priority order of a carrier according to the signal with the highest priority among the signals on all antenna panels of a carrier, and then according to the priority order of multiple carriers from high to low Power allocation is performed on the signals on the multiple carriers, so that the total transmission power of the signals on the multiple carriers does not exceed the maximum transmission power. That is to say, the power allocation is based on the unit of the carrier, not the unit of the signal.

Exemplarily, the terminal device is configured with carriers A, B and C, where antenna panel 1 and antenna panel 2 on carrier A transmit signal 1 and signal 2 respectively, and antenna panel 1 and antenna panel 2 on carrier B transmit signal 3 respectively And signal 4, signal 5 is transmitted on carrier C, and the priority order of the signals is {signal 2, signal 5, signal 4, signal 3, signal 1}, then the terminal device according to the priority order of the signals on these three carriers , to determine the priority order of the carriers, so as to perform power allocation on these carriers. Therefore, it can be determined that the priority order of the carriers is {carrier A, carrier C, carrier B}, then the terminal device first distributes the expected transmission power of carrier A to carrier A, and distributes the expected transmission power of carrier C to carrier C (that is, The power on carriers A and C remains unchanged), and the remaining power is allocated to carrier B (that is, the transmit power on carrier B is reduced).

In an optional implementation manner, if the sum of the expected transmission powers of the signals of the terminal device on multiple carriers does not exceed the maximum transmission power that the terminal device can support on all carriers, the terminal device can directly transmit the signal of each carrier to The expected transmit power is used as the actual transmit power of the carrier.

Step 203, if the total transmission power of the terminal device's signals on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device prioritizes the first transmission power and the signals on the multiple antenna panels from high to high Power allocation is performed on the signals on the multiple antenna panels in sequence until the total transmission power of the signals on the multiple antenna panels is equal to the first transmission power.

Step 203 of this embodiment is similar to step 102 of the embodiment in FIG. 4 , and details may be referred to the foregoing embodiments, and details are not repeated here.

In the power allocation method shown in this embodiment, the terminal device first determines the second transmit power allowed on the first carrier, uses the second transmit power as the expected transmit power on the first carrier, and performs power allocation on multiple carriers, and determines First transmit power of the terminal device on the first carrier, where the first transmit power is actual transmit power on the first carrier. If the total transmit power of the terminal device’s signals on the multiple antenna panels of the first carrier is greater than the first transmit power, the terminal device performs the first transmit power and the priority order of the signals on the multiple antenna panels from high to low. Power allocation is performed on the signals on the multiple antenna panels until the total transmission power of the signals on the multiple antenna panels is equal to the first transmission power.

The above scheme first performs multi-carrier power allocation, and then performs power allocation for multiple antenna panels on each carrier, finally ensuring priority transmission of important information on carriers with higher priority and multiple antenna panels on the carrier, and improving terminal uplink transmission performance.

FIG. 6 is a third flowchart of the power allocation method provided by the embodiment of the present application. As shown in FIG. 6, the power allocation method of this embodiment can be used in a carrier aggregation scenario, and the method includes:

Step 301. The terminal device determines the first transmit power allowed on the first carrier.

In this step, the first transmission power is the maximum transmission power supported by the terminal device on the first carrier. Wherein, the maximum transmission power may be determined by the terminal device and reported to the network device, or may be configured by the network device to the terminal device, which is not limited in this embodiment of the present application.

Step 302: If the total transmission power of the terminal device's signals on the multiple antenna panels of the first carrier is greater than the first transmission power, the terminal device transmits the signals according to the first transmission power and the priority of the signals on the multiple antenna panels of the first carrier Power allocation is performed on the signals on the multiple antenna panels of the first carrier in order from high to low, until the total transmission power of the signals on the multiple antenna panels is equal to the first transmission power.

Step 302 of this embodiment is similar to step 102 of the embodiment in FIG. 4 , and details may be referred to the foregoing embodiments, and details are not repeated here.

Step 303, the terminal device uses the sum of the transmission powers of the signals on the multiple antenna panels of the first carrier after power allocation as the expected transmission power on the first carrier, performs power allocation on multiple carriers, and determines the first carrier on the actual transmit power.

Optionally, the expected transmit power on the first carrier may be equal to the first transmit power.

Optionally, if the signals on some antenna panels of the first carrier are not transmitted because the power is too low, the sum of the transmission powers of the signals on the multiple antenna panels of the first carrier after multi-carrier power allocation (that is, the first expected transmit power on a carrier) may be less than the first transmit power.

In this embodiment, the terminal device allocates power on multiple carriers and determines the actual transmission power on the first carrier for a specific implementation manner, which may refer to step 202 in the embodiment in FIG. 5 , which will not be repeated here.

In an optional implementation manner, if the power of the first carrier is not reduced during the multi-carrier power allocation process (that is, the priority order of the first carrier is higher), the actual transmission power on the first carrier is equal to The expected transmit power on a carrier.

In an optional implementation manner, if the power of the first carrier is reduced in the process of multi-carrier power allocation (that is, the priority order of the first carrier is lower), the actual transmission power on the first carrier is less than the first The expected transmit power on the carrier.

Step 304: If the actual transmit power of the terminal device on the first carrier is smaller than the expected transmit power on the first carrier, the terminal device reduces the transmit power of signals on at least one antenna panel among the plurality of antenna panels of the first carrier.

In an optional implementation manner, if the actual transmit power of the terminal device on the first carrier is less than the expected transmit power on the first carrier, the terminal device may The priority order of the signals on the multiple antenna panels is from low to high and the transmit power of the signals on the multiple antenna panels is sequentially reduced until the total transmit power of the signals on the multiple antenna panels of the first carrier is equal to that of the first carrier. Actual transmit power. Optionally, the priority order of the signal includes at least one of the first priority order, the second priority order, and the third priority order in the foregoing embodiments.

In an optional implementation manner, if the actual transmit power of the terminal device on the first carrier is less than the expected transmit power on the first carrier, the terminal device may reduce the power of the signals on the multiple antenna panels of the first carrier in the same proportion. transmit power until the total transmit power of the signals on the multiple antenna panels of the first carrier is equal to the actual transmit power on the first carrier (that is, the total transmit power of the signals on the multiple antenna panels of the first carrier after the transmit power is reduced not exceed the actual transmit power on the first carrier).

In the power allocation method shown in this embodiment, the terminal device first determines the first transmit power allowed on the first carrier, and if the total transmit power of the signals of the terminal device on the multiple antenna panels of the first carrier is greater than the first transmit power, the terminal The device performs power allocation on the signals on the multiple antenna panels of the first carrier in sequence according to the first transmit power and the priority order of the signals on the multiple antenna panels of the first carrier from high to low. The sum of the transmission powers of the signals on the multiple antenna panels of the first carrier after the above power allocation is used as the expected transmission power on the first carrier, so as to perform power allocation on multiple carriers, and determine the power on the first carrier. Actual transmit power. If the actual transmit power of the terminal device on the first carrier is less than the expected transmit power on the first carrier, the terminal device will use the actual transmit power on the first carrier and the priority order of the signals on the multiple antenna panels of the first carrier The transmit power of the signals on the multiple antenna panels is decreased in sequence from low to high until the total transmit power of the signals on the multiple antenna panels of the first carrier is equal to the actual transmit power of the first carrier.

The above scheme first allocates the power of multiple antenna panels of each carrier, then allocates the power of multiple carriers, and finally allocates the power of the signals of multiple antenna panels of each carrier, and finally ensures the carrier with higher priority And important information on multiple antenna panels on the carrier is transmitted preferentially, improving the uplink transmission performance of the terminal.
