[0044] See Figure 1 , the technical solution provided by the embodiment of the present application is applied to a communication system, which includes a network device 11 and a terminal device 10.

[0045] The network device 11 is a device that provides wireless communication functions for the terminal. Exemplarily, the network device may also be referred to as an access network device. The network device 11 includes, but is not limited to: gNB in 5G, Radio Network Controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., Home evolved NodeB, or Home Node B, HNB), Base Band Unit (BBU), Transmitting and Receiving Point (TRP), Transmitting Point (TP), mobile switching center, etc. The network device in this application may also be a device that provides wireless communication functions for the terminal in other future possible communication systems. With the evolution of communication technologies, the name of the "network device" may change. For ease of description, in the embodiments of this application, the devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices.

[0046] The TRP in the embodiments of this application may refer to any component (or set of components) used to provide wireless access to the network, such as a macro cell, a femto cell, a Wi-Fi access point (AP), or other devices that support wireless communication. The TRP may provide wireless access according to one or more wireless communication protocols, such as the 5th Generation New Radio (5G NR), Long Term Evolution (LTE), LTE Advanced (LTE-A), High Speed Packet Access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. th Generation New Radio, 5G NR), Long Term Evolution (LTE), LTE Advanced (LTE-A), High Speed Packet Access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc.

[0047] Exemplarily, one access network device deploys one or more TRPs. For example, the access network device corresponds to a first TRP and a second TRP. Or, the first access network device corresponds to the first TRP, and the second access network device corresponds to the second TRP.

[0048] The terminal device 10 is a device that can provide voice and / or data connectivity to users. For example, the terminal device includes handheld devices, vehicle-mounted devices, etc. with wireless communication functions. Currently, the terminal device can be: a mobile phone, a tablet computer, a laptop computer, a handheld computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, a vehicle-mounted device, a computing device, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), Mobile Station (MS), etc.

[0049] It should be noted that the above system architecture is only an example of the system architecture applicable to the embodiments of the present application. The system architecture applicable to the embodiments of the present application may have additional entities or fewer entities compared to Figure 1 the system architecture shown.

[0050] Optionally, the terminal device has multiple panels, and the terminal device supports simultaneous transmission on multiple panels. The multiple panels can perform uplink transmission or downlink transmission simultaneously. For example, the terminal device has two panels, and the two panels respectively send uplink channels / uplink signals to two TRPs. Generally speaking, the orientations of the multiple panels are very different, so the Quasi Co-Location (QCL), that is, the SpatialRelationInfo, corresponding to the uplink PUSCH transmission of the multiple panels is different.

[0051] Exemplarily, a network device 11 is deployed with one or more TRPs. For example, the network device 11 corresponds to TRP1 and TRP2. The terminal device uses different panels to send beams in different directions. The terminal device uses different transmission beams to face different TRPs for repeated transmission of the uplink channel. The network device 11 receives the repeated transmission of the uplink channel sent by the terminal device through multiple TRPs. Exemplarily, due to the different relative orientations of different TRPs and the terminal device, the terminal device needs to use transmission beams with different beam directions to send beams to the TRPs in the corresponding directions for repeated transmission of the uplink channel.

[0052] The technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced long Term Evolution (LTE-A) system, New Radio (NR) system, evolved system of the NR system, LTE-based access to Unlicensed spectrum (LTE-U) system, NR-U system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication system or other communication systems, etc.

[0053] In R17, the transmission of PUSCH (Physical Uplink Shared Channel) from a terminal device to multiple base station TRPs is standardized. It mainly standardizes the coordinated transmission in the TDM (Time Division Multiplexing) transmission mode, enabling the terminal device to send different repetitions of the same information on PUSCH to different TRPs of the base station at different transmission occasions (TOs) in the time domain. This method has relatively low requirements for the capabilities of the terminal device, does not require the terminal device to support the ability to simultaneously transmit beams, and has a relatively large transmission delay.

[0054] For uplink transmission, for PUSCH channels facing different TRPs, the spatial characteristics of the actual channels they pass through may vary greatly. Therefore, it is considered that the QCL-D (Quasi-Colocation Type D) of PUSCHs in different transmission directions is different.

[0055] In R18, it is desired to achieve simultaneous coordinated transmission from multiple antenna panels of a terminal device to the TRPs of multiple base stations to increase transmission reliability and throughput, and at the same time effectively reduce the transmission delay under multiple TRPs. However, this scheme requires the terminal device to have the ability to simultaneously transmit multiple beams. The transmission of PUSCH can be multi-panel / TRP transmission based on a single PDCCH (Physical Downlink Control Channel), that is, multi-panel / TRP transmission based on S-DCI (single DCI) scheduling. For example, as Figure 2 shown, the terminal device 10 receives PDCCH1 sent by TRP1. DCI1 is carried in PDCCH1, and the scheduling information of PUSCH1 and PUSCH2 is included in DCI1. The terminal device sends PUSCH1 to TRP1 through panel1 according to DCI1, and sends PUSCH2 to TRP2 through panel2 according to DCI1. The transmission of PUSCH can also be multi-panel / TRP transmission based on different PDCCHs, that is, M-DCI (Multi DCI) scheduling. For example, as Figure 3 shown, the terminal device 10 receives PDCCH1 sent by TRP1 and PDCCH2 sent by TRP2. DCI1 is carried in PDCCH1, and the scheduling information of PUSCH1 is included in DCI1. DCI2 is carried in PDCCH2, and the scheduling information of PUSCH2 is included in DCI2. The terminal device sends PUSCH1 to TRP1 through panel1 according to DCI1, and sends PUSCH2 to TRP2 through panel2 according to DCI2.

[0056] In actual deployment, the link between the panel and the TRP may be a relatively ideal backhaul link that supports high throughput and very low backhaul latency, or it may be a non-ideal backhaul link using methods such as xDSL (x Digital Subscriber Line), microwave, and relay. The NC-JT (Non-Coherent Joint Transmission) transmission scheme based on M-DCI was initially mainly introduced for non-ideal backhaul situations, but it can also be used in ideal backhaul situations.

[0057] In the R18 uplink MIMO (Multiple Input Multiple Output) enhancement, it is considered to achieve simultaneous uplink transmission for multiple TRPs through multiple panels of the terminal device to further improve the uplink system transmission throughput and transmission reliability.

[0058] In the PDSCH (Physical Downlink Shared Channel) scheduled based on M-DCI, the time-frequency resource allocation of different PDSCHs supports fully / partially / non-overlapping situations. When considering supporting the PUSCH scheduled based on M-DCI, similar resource allocation situations will also be taken into account. In the M-DCI PUSCH transmission scheme of R16, it mainly supports cooperative transmission in the TDM (Time Division Multiplexing) mode. Currently, it is necessary to discuss which resource allocation situations are supported and how to support them under the premise of a multi-panel terminal.

[0059] In the case of different PUSCH time-domain resource allocations, as shown in Formula 1, the current PUSCH power control is mainly carried out for the transmission opportunity. To support the allocation of overlapping resources, relevant enhancement schemes need to be considered.

[0060] Formula 1:

[0061]

[0062] Among them, P PUSCH,p,f,c (i, j, q d , l) is the transmission power of the terminal device for transmitting PUSCH at the i-th transmission opportunity; P CMAX,f,c (i) is the maximum transmission power on the serving cell c and carrier f determined by the terminal power level, which is configured by high-layer signaling; is the PUSCH power target value, given by the parameters configured by higher layer signaling. The base station can configure multiple sets of parameter sets for the terminal device, and j is the index of the parameter set; is the PUSCH cell-level expected received power, is the UE-level power deviation of PUSCH under dynamic scheduling; μ is the NR parameter set, related to the subcarrier spacing; is the number of RBs (Resource Blocks) occupied by the terminal device to transmit PUSCH at the i-th PUSCH transmission occasion; α b,f,c (j) is the path loss compensation factor, where j is the index of the parameter set; PL b,f,c (q d ) is the path loss measured by the terminal device, q d is the index of the reference signal used to measure the path loss; Δ TF,b,f,c (i) represents the power offset determined by the MCS (Modulation and Coding Scheme) level; f b,f,c (i, l) is the closed-loop power control adjustment value, where l is the index of the closed-loop power control state, obtained by mapping the TPC (Transmit Power Control) information in the PDCCH.

[0063] That is, the transmit power of the terminal device to transmit PUSCH is the minimum value of the maximum transmit power P CMAX,f,c (i) and in.

[0064] Please refer to Figure 4 , which shows the flowchart of the uplink power control method provided by an embodiment of the present application. This method can be applied to the Figure 1 shown communication system, and this method is executed by the terminal device. The method includes the following steps.

[0065] Step 210: Receive the configuration information of the maximum transmit power sent by the access network device. The configuration information of the maximum transmit power is used to determine the panel maximum transmit power P corresponding to the terminal device's uplink transmission from two antenna panels respectively in the case of simultaneous transmission via multi-panel (STxMP) through multi-DCI scheduling CMAX,P .

[0066] Among them, the terminal device includes multiple antenna panels, and the terminal device supports simultaneous uplink transmission of multiple antenna panels. For example, the terminal device includes two, three, four or more panels. Optionally, the terminal device includes two panels: the first panel (the first antenna panel) and the second panel (the second antenna panel). The terminal device supports simultaneous uplink transmission of the first panel and the second panel.

[0067] In a possible implementation manner, the maximum transmit power P corresponding to each of at most two antenna panels of the terminal device for uplink transmission can be determined. CMAX,P .

[0068] Exemplarily, the terminal device receives an RRC message sent by the access network device, and the RRC message carries configuration information of the maximum transmit power.

[0069] The configuration information of the maximum transmit power includes one of the following:

[0070] · Configuration information of the maximum transmit power P of the terminal device of the terminal; CMAX ;

[0071] · Configuration information of the maximum transmit power P corresponding to each antenna panel of the terminal device; CMAX,P ;

[0072] · Configuration information of the maximum transmit power P of the terminal device of the terminal, and configuration information of the maximum transmit power P corresponding to each antenna panel of the terminal device. CMAX CMAX,P ;

[0073] That is, the embodiments of the present application provide three configuration types for the maximum transmit power P allowed by the terminal device on a certain carrier: CMAX

[0074] · Configuration type 1: Only configure the maximum transmit power P of the terminal on a certain carrier determined by the power level for the terminal device; CMAX ;

[0075] · Configuration type 2: Configure the maximum transmit power P of each panel for the terminal device supporting simultaneous uplink transmission of multiple panels; CMAX,p ;

[0076] · Configuration type 3: Configure the above two configuration information for the terminal device at the same time, that is, configure the maximum transmit power P of the terminal device and the maximum transmit power P of each panel at the same time. CMAX CMAX,p ;

[0077] Exemplarily, the maximum transmit power of the terminal device can be referred to as the terminal maximum transmit power P CMAX ; the maximum transmit power of the panel can be referred to as the panel maximum transmit power P CMAX,p ; p1 in P CMAX,p1 represents the panel maximum transmit power of panel1 (the first panel), and p2 in P CMAX,p2 represents the panel maximum transmit power of panel2 (the second panel).

[0078] The terminal device receives multiple DCIs sent by the access network device, and the multiple DCIs schedule multiple panels of the terminal device to perform uplink transmission simultaneously.

[0079] Exemplarily, if the access network device schedules two panels of the terminal device to perform uplink transmission simultaneously through two DCIs, the terminal device determines the panel maximum transmit power P corresponding to each panel for uplink transmission respectively according to the configuration information of the maximum transmit power CMAX,p .

[0080] Exemplarily, the terminal device determines the panel maximum transmit power P corresponding to each panel for uplink transmission respectively according to the configuration of the maximum transmit power of the two scheduled panels in the configuration information of the maximum transmit power CMAX,p .

[0081] If the access network device configures the maximum transmit power for the terminal device using the above configuration type 2 or configuration type 3, the access network device can configure the panel maximum transmit power P for some or all panels of the terminal device CMAX,p . For example, the terminal device has four panels, and the access network device configures the terminal maximum transmit power P CMAX for the terminal device, as well as the panel maximum transmit power P corresponding to the first panel and the second panel respectively CMAX,p .

[0082] Then, the two panels scheduled by the access network device through two DCIs may be configured with the panel maximum transmit power P CMAX,p or may not be configured with the panel maximum transmit power P CMAX,p , and the terminal device can adopt the corresponding method to determine the panel maximum transmit power P of each panel according to the configuration of the maximum transmit power CMAX,p .

[0083] For example, the access network device schedules the first panel and the second panel of the terminal device to perform uplink transmission simultaneously through two DCIs. When the configuration information of the maximum transmit power includes the terminal maximum transmit power P CMAX, and does not include the maximum transmit power P of the first panel and the second panel CMAX,p When it is, the configuration information of the terminal device using the maximum transmit power includes the maximum transmit power P of the terminal CMAX Determine the maximum transmit power P of each of the first panel and the second panel according to the method corresponding to the configuration information (for example, Method 1, Method 2, Method 3, or Method 4 below) CMAX,p .

[0084] When the configuration information of the maximum transmit power does not include the maximum transmit power P of the terminal CMAX , and includes the maximum transmit power P of the first panel and the second panel CMAX,p When it is, the configuration information of the terminal device using the maximum transmit power includes the maximum transmit power P of each antenna panel of the terminal device CMAX,P Determine the maximum transmit power P of each of the first panel and the second panel according to the method corresponding to the configuration information (for example, Method 5 below) CMAX,p .

[0085] When the configuration information of the maximum transmit power includes the maximum transmit power P of the terminal CMAX , and includes the maximum transmit power P of the first panel and the second panel CMAX,p When it is, the configuration information of the terminal device using the maximum transmit power includes the configuration information of the maximum transmit power P of the terminal device and the maximum transmit power P of each of the two antenna panels CMAX Determine the maximum transmit power P of each of the first panel and the second panel according to the method corresponding to the configuration information (for example, Method 6, Method 7, Method 8, or Method 9 below) CMAX,P . CMAX,p .

[0086] Simultaneous transmission means that the transmission opportunities of multiple uplink transmissions have full / partial-overlap in the time domain, and the corresponding frequency domain resources can be full / partial / non-overlap.

[0087] For example, the terminal device receives the first PDCCH sent by the first TRP through the first panel. The first PDCCH includes the first DCI, and the first DCI schedules the first panel to send the first uplink channel (such as PUSCH or PUCCH (Physical Uplink Control Channel)) / the first uplink signal at the first transmission opportunity; the terminal device receives the second PDCCH sent by the second TRP through the second panel. The second PDCCH includes the second DCI, and the second DCI schedules the second panel to send the second uplink channel / the second uplink signal at the second transmission opportunity. Among them, there are overlapping symbols in the time domain between the first transmission opportunity and the second transmission opportunity, the first transmission opportunity and the second transmission opportunity.

[0088] In the case of scheduling multiple panels to perform uplink transmission simultaneously through multiple DCIs, the terminal device determines the maximum transmit power of each of the two panels for uplink transmission respectively according to the configuration information of the maximum transmit power P CMAX,P . That is, the terminal device determines the maximum transmit power P of the first panel for the first uplink transmission according to the configuration information of the maximum transmit power CMAX,P1 ; the terminal device determines the maximum transmit power P of the second panel for the second uplink transmission according to the configuration information of the maximum transmit power CMAX,P2 .

[0089] The configuration information of the maximum transmit power is used to determine the maximum transmit power P of the first panel for uplink transmission from the first antenna panel in the case of scheduling multiple antenna panels to perform uplink simultaneous transmission STxMP through multiple downlink control information DCIs CMAX,P1 ; the configuration information of the maximum transmit power is used to determine the maximum transmit power P of the second panel for uplink transmission from the second antenna panel in the case of scheduling multiple antenna panels to perform uplink simultaneous transmission STxMP through multiple downlink control information DCIs CMAX,P2 .

[0090] Exemplarily, the terminal device determines the maximum transmit power P of the panel CMAX,P at the symbol level, that is, the terminal device determines the maximum transmit power P of the panel for each symbol within the transmission opportunity CMAX,P .

[0091] The first panel is used for the first uplink transmission, and the second panel is used for the second uplink transmission. There is a time-domain overlap in the transmission time slot between the first transmission opportunity of the first uplink transmission and the second transmission opportunity of the second uplink transmission; the configuration information of the maximum transmit power is used to determine the maximum transmit power P of the first panel for each symbol at the first transmission opportunity CMAX,P1; The configuration information of the maximum transmit power is used to determine the maximum transmit power P of the second panel on each symbol at the second transmission opportunity CMAX,P2 .

[0092] In summary, the method provided in this embodiment enables the terminal device to determine the maximum transmit power for each panel to perform uplink transmission respectively according to the configuration information of the maximum transmit power when the terminal device schedules multiple panel uplink simultaneous transmissions through M-DCI, so as to achieve power control for multiple panel uplink simultaneous transmissions by configuring the configuration information of the maximum transmit power for the terminal device.

[0093] Please refer to Figure 5 , which shows a flowchart of the uplink power control method provided in an embodiment of the present application. This method can be applied to Figure 1 the communication system shown, and this method is executed by the access network device. This method includes the following steps.

[0094] Step 220: Send the configuration information of the maximum transmit power to the terminal device. The configuration information of the maximum transmit power is used to determine the maximum transmit power P of the terminal device for uplink transmission from two antenna panels respectively when scheduling multiple antenna panel uplink simultaneous transmissions STxMP through multiple downlink control information DCI CMAX,P .

[0095] Among them, the terminal device includes multiple antenna panels, and the terminal device supports uplink simultaneous transmissions of multiple antenna panels.

[0096] In a possible implementation manner, the maximum transmit power P corresponding to uplink transmission can be determined for at most two antenna panels of the terminal device respectively CMAX,P .

[0097] Exemplarily, the access network device configures the maximum transmit power for the terminal device.

[0098] The access network device can configure the maximum transmit power P of the terminal device CMAX , and / or the access network device can configure the maximum transmit power P of each panel of the terminal device respectively CMAX,p .

[0099] Exemplarily, when the access network device schedules multiple panels of the terminal device to perform uplink transmission simultaneously, the terminal device can determine the maximum transmit power P corresponding to each panel respectively according to the maximum transmit power configured by the access network device CMAX,p .

[0100] Exemplarily, the access network device configures the maximum transmit power P of the terminal device according to the power class of the terminal device CMAX . The power class of the terminal device is the maximum output power of any transmission bandwidth within the channel bandwidth of the NR carrier. The power class of the terminal device corresponds to the maximum transmit power P CMAX , or, the power class corresponds to the range of values of the maximum transmit power P CMAX .

[0101] The embodiments of the present application provide a power control enhancement scheme for uplink multi-panel simultaneous transmission based on M-DCI scheduling. For uplink transmissions (e.g., PUSCH) performed by different panels, when the transmission opportunities in the same time slot have time-domain overlap, frequency-domain overlap, or no overlap, a variety of power enhancement control schemes are provided to achieve simultaneous uplink transmission from multiple panels to multiple TRPs, improving the throughput and transmission reliability of the uplink transmission.

[0102] In summary, the method provided in this embodiment enables the terminal device to determine the maximum transmit power for uplink transmission of each panel respectively according to the configuration information of the maximum transmit power when scheduling multi-panel uplink simultaneous transmission through M-DCI by configuring the configuration information of the maximum transmit power for the terminal device, so as to achieve power control for multi-panel uplink simultaneous transmission.

[0103] Exemplarily, an exemplary embodiment of the interaction between the terminal device and the access network device is given.

[0104] Please refer to Figure 6 , which shows a flowchart of the uplink power control method provided by an embodiment of the present application. This method can be applied to Figure 1 the communication system shown, and this method is executed by the terminal device and the access network device. The method includes the following steps.

[0105] Step 301: The access network device sends an RRC message to the terminal device, and the RRC message includes the configuration information of the maximum transmit power.

[0106] The access network device configures the maximum transmit power for the terminal device through the RRC message. The terminal device receives the RRC message sent by the access network device and reads the configuration information of the maximum transmit power in the RRC message.

[0107] For example, the access network device configures the terminal maximum transmit power P CMAX .

[0108] Alternatively, the access network device configures the maximum transmit power P of the first panel for the terminal device CMAX,p1 and the maximum transmit power P of the second panelCMAX,p2 。

[0109] Alternatively, the access network device configures the maximum transmit power P of the terminal device for the terminal device CMAX , the maximum transmit power P of the first panel CMAX,p1 and the maximum transmit power P of the second panel CMAX,p2 。

[0110] Step 302: The access network device sends a first DCI to the first panel of the terminal device through the first TRP.

[0111] The first DCI is used to schedule the terminal device to send a first uplink channel (e.g., PUSCH or PUCCH) / a first uplink signal (e.g., SRS (Sounding Reference Signal)) to the first TRP through the first panel at a first transmission opportunity.

[0112] Step 303: The access network device sends a second DCI to the second panel of the terminal device through the second TRP.

[0113] The second DCI is used to schedule the terminal device to send a second uplink channel (e.g., PUSCH or PUCCH) / a second uplink signal (e.g., SRS) to the second TRP through the second panel at a second transmission opportunity.

[0114] Wherein, there is an overlapping symbol in the time domain between the first transmission opportunity and the second transmission opportunity. For example, as Figure 7 shown, the first transmission opportunity includes symbols 0 to 4; the second transmission opportunity includes symbols 2 to 6. There is an overlapping symbol in the time domain between the first transmission opportunity and the second transmission opportunity: symbols 2 to 4.

[0115] The first transmission opportunity and the second transmission opportunity overlap / partially overlap / do not overlap in the frequency domain.

[0116] That is, the access network device schedules the first panel and the second panel to perform uplink transmission simultaneously through multiple DCIs.

[0117] Step 304: In the case of scheduling multiple panels to perform uplink transmission simultaneously through multiple DCIs, the terminal device determines the panel maximum transmit power P of multiple panels respectively according to the configuration information of the maximum transmit power CMAX,p 。

[0118] In a possible implementation manner, the panel maximum transmit power P corresponding to each uplink transmission can be determined for at most two antenna panels of the terminal device CMAX,P 。

[0119] Exemplarily, according to different maximum transmission power configuration types, embodiments of the present application provide multiple methods for determining the maximum panel transmission power P of each panel, which will be described separately in the subsequent embodiments. CMAX,p

[0120] Exemplarily, the first transmission opportunity and the second transmission opportunity have overlapping symbols in the time domain, and the overlapping symbols include at least one symbol. The terminal device determines the first panel maximum transmission power P of the first panel on the overlapping symbols according to the configuration information of the maximum transmission power; determines the second panel maximum transmission power P of the second panel on the overlapping symbols according to the configuration information of the maximum transmission power. CMAX,p1 CMAX,p2

[0121] Optionally, the first transmission opportunity further includes first non-overlapping symbols that do not overlap with the second transmission opportunity, and the first non-overlapping symbols include at least one symbol. The terminal device determines the first panel maximum transmission power P of the first panel on the first non-overlapping symbols according to the configuration information of the maximum transmission power. CMAX,p1

[0122] Optionally, the second transmission opportunity further includes second non-overlapping symbols that do not overlap with the first transmission opportunity, and the second non-overlapping symbols include at least one symbol. The terminal device determines the second panel maximum transmission power P of the second panel on the second non-overlapping symbols according to the configuration information of the maximum transmission power. CMAX,p2

[0123] Step 305: The terminal device performs a first uplink transmission to the first TRP through the first panel according to the first panel maximum transmission power P. CMAX,p1

[0124] Exemplarily, the terminal device controls the transmission power of each panel according to the maximum panel transmission power P of each panel. CMAX,p

[0125] For example, the terminal device controls the transmission power of the PUSCH sent by the first panel on each symbol within the first transmission opportunity according to Formula 2.

[0126] Formula 2:

[0127]

[0128] where P PUsCH,p1,p,f,c (i, j, q d , l, a) is the transmission power of the PUSCH sent by the terminal device through the first panel on the a-th symbol in the i-th transmission opportunity; P CMAX,p1,f,c ​​​​​​​(i, a) is the maximum transmit power for transmitting PUSCH on the a-th symbol of the first panel at the i-th transmission occasion; is the power target value corresponding to the PUSCH transmitted by the first panel, given by the parameters configured by high-layer signaling. The base station can configure multiple sets of parameter sets for the terminal device, and j is the index of the parameter set; is the cell-level expected received power of the PUSCH, is the UE-level power deviation of the PUSCH under dynamic scheduling; μ is the NR parameter set corresponding to the PUSCH transmitted by the first panel, which is related to the subcarrier spacing; is the number of RBs (Resource Blocks) occupied by the terminal device's first panel for transmitting PUSCH at the i-th PUSCH transmission occasion; α b,f,c (j) is the path loss compensation factor corresponding to the PUSCH transmitted by the first panel, and j is the index of the parameter set; PL b,f,c (q d ) is the path loss corresponding to the PUSCH transmitted by the first panel; Δ TF,b,f,c (i) represents the power offset determined by the MCS level; f b,f,c (i, l) is the closed-loop power control adjustment value corresponding to the PUSCH transmitted by the first panel, and l is the index of the closed-loop power control state corresponding to the PUSCH transmitted by the first panel, obtained by mapping the TPC information in the PDCCH.

[0129] That is, the transmit power of the terminal device for transmitting the first PUSCH on symbol a through the first panel is: the minimum value between the maximum transmit power P CMAX,p1,f,c (i, a) of the first panel for transmitting PUSCH on symbol a and in.

[0130] Step 306: The terminal device performs a second uplink transmission to the second TRP through the second panel according to the maximum transmit power P CMAX,p2 of the second panel.

[0131] For example, the terminal device controls the transmit power of the second panel for transmitting PUSCH on each symbol within the second transmission occasion according to Formula 3.

[0132] Formula 3:

[0133]

[0134] Among them, P PUSCH,p2,p,f,c (i, j, q d,l,a) is the transmission power of the PUSCH sent by the terminal device through the second panel at the a-th symbol in the i-th transmission occasion; P CMAX,p2,f,c (i,a) is the maximum transmission power of the PUSCH sent by the second panel at the a-th symbol in the i-th transmission occasion; is the power target value corresponding to the PUSCH sent by the second panel, given by the parameters configured by the higher layer signaling. The base station can configure multiple sets of parameter sets for the terminal device, and j is the index of the parameter set; is the cell-level expected reception power of the PUSCH, is the UE-level power deviation of the PUSCH under dynamic scheduling; μ is the NR parameter set corresponding to the PUSCH sent by the second panel, which is related to the subcarrier spacing; is the number of RBs (Resource Blocks) occupied by the terminal device's second panel to send the PUSCH at the i-th PUSCH transmission occasion; α b,f,c (j) is the path loss compensation factor corresponding to the PUSCH sent by the second panel, and j is the index of the parameter set; PL b,f,c (q d ) is the path loss corresponding to the PUSCH sent by the second panel; Δ TF,b,f,c (i) represents the power offset determined by the MCS level; f b,f,c (i,l) is the closed-loop power control adjustment value corresponding to the PUSCH sent by the second panel, and l is the index of the closed-loop power control state corresponding to the PUSCH sent by the second panel, obtained by mapping the TPC information in the PDCCH.

[0135] That is, the transmission power of the terminal device to send the second PUSCH through the second panel at symbol a is: the minimum value of the maximum transmission power P CMAX,p2,f,c (i,a) and in.

[0136] In summary, for the method provided in this embodiment, by configuring the configuration information of the maximum transmission power for the terminal device, when the terminal device schedules multi-panel uplink simultaneous transmission through M-DCI, it determines the maximum transmission power for each panel to perform uplink transmission according to the configuration information of the maximum transmission power, and then determines the transmission power for each panel to perform uplink transmission according to the maximum transmission power corresponding to each panel, thereby realizing power control for uplink transmission. Moreover, for the case where multiple uplink transmission opportunities overlap in the time domain, it is possible to separately determine the maximum panel transmission power of a panel on each symbol within the transmission opportunity, realizing symbol-level power control and improving the power control accuracy.

[0137] Exemplarily, for different configuration situations of the maximum transmission power of the two scheduled panels, this embodiment of the present application provides various methods for determining the maximum panel transmission power of each panel.

[0138] 1. The configuration information of the maximum transmission power includes: the terminal maximum transmission power P CMAX of the terminal device.

[0139] Adopt one of the following methods to determine the maximum panel transmission power P corresponding to uplink transmission from each of the two antenna panels CMAX,P :

[0140] In a possible implementation manner, one of the following methods can be adopted to determine the maximum panel transmission power P corresponding to uplink transmission from each of at most two antenna panels of the terminal device CMAX,P .

[0141] Method 1: Divide the terminal maximum transmission power P CMAX to obtain the maximum panel transmission power P corresponding to uplink transmission from each of the two antenna panels CMAX,P .

[0142] For example, the access network device sends the configuration information of the terminal maximum transmission power P CMAX to the terminal device, and configures the terminal maximum transmission power P CMAX as 26 dbm. Then, the maximum transmission power of the first panel of the first panel is 1 / 2 * 26 dbm = 23 dbm; the maximum transmission power of the second panel of the second panel is 1 / 2 * 26 dbm = 23 dbm.

[0143] Method 2: Allocate the terminal maximum transmission power P according to the power allocation factor CMAX to obtain the maximum panel transmission power P corresponding to uplink transmission from each of the two antenna panels CMAX,PAmong them, the power allocation factor is predefined, or the power allocation factor is configured by the network device, or the power allocation factor is reported by the terminal device.

[0144] For example, the power allocation factor is the ratio A of the maximum transmission power P of the first panel CMAX,P1 to the maximum transmission power P of the second panel CMAX,P2 , that is, A = P CMAX,P1 / P CMAX,P2 . Then the maximum transmission power P of the first panel CMAX,P1 is equal to A * P CMAX / (1 + A); the maximum transmission power P of the second panel CMAX,P2 is equal to P CMAX / (1 + A).

[0145] Alternatively, the first panel has a first power allocation factor a, and the second panel has a second power allocation factor b, where a + b = 1; then the maximum transmission power P of the first panel CMAX,P1 is equal to a * P CMAX ; the maximum transmission power P of the second panel CMAX,P2 is equal to b * P CMAX .

[0146] Exemplarily, the terminal device receives the configuration information of the power allocation factor sent by the access network device. Alternatively, the terminal device reads the power allocation factor stored locally. Alternatively, the terminal device reports the power allocation factor to the access network device.

[0147] For example, the terminal device determines the power allocation factor according to the transmission capabilities of the two panels and reports the power allocation factor to the access network device.

[0148] Method 3: Determine the respective panel maximum transmission powers P for uplink transmission from the two antenna panels according to the indication information CMAX,P , where the indication information is used to indicate the respective panel maximum transmission powers P of the two antenna panels CMAX,P .

[0149] Optionally, the access network device sends indication information to the terminal device, where the indication information is used to indicate the panel maximum transmission power P of the first panel CMAX,P1 and the panel maximum transmission power P of the second panel CMAX,P2 .

[0150] Exemplarily, the two antenna panels of the terminal device include a first antenna panel and a second antenna panel. The first antenna panel is used for the first uplink transmission in the first transmission opportunity, and the second antenna panel is used for the second uplink transmission in the second transmission opportunity. There are overlapping symbols between the first transmission opportunity and the second transmission opportunity within the transmission time slot. For example, as Figure 7As shown, there are overlapping symbols in the transmission time slot between the first transmission opportunity and the second transmission opportunity: symbol 2, symbol 3, and symbol 4.

[0151] Optionally, the first transmission opportunity further includes first non - overlapping symbols that do not overlap with the second transmission opportunity in the transmission time slot. For example, the first transmission opportunity further includes first non - overlapping symbols that do not overlap with the second transmission opportunity in the transmission time slot: symbol 0, symbol 1.

[0152] Optionally, the second transmission opportunity further includes second non - overlapping symbols that do not overlap with the first transmission opportunity in the transmission time slot. For example, the second transmission opportunity further includes second non - overlapping symbols that do not overlap with the first transmission opportunity in the transmission time slot: symbol 5, symbol 6.

[0153] Exemplarily, for the overlapping relationship of symbols in the above two transmission opportunities, the panel maximum transmit power at each symbol is determined respectively.

[0154] For overlapping symbols, the above - mentioned method 1, method 2, or method 3 can be used to determine the panel maximum transmit power of the panel at each symbol respectively.

[0155] That is, for the uplink transmission on overlapping symbols, one of the following methods is used to determine the respective panel maximum transmit power \(P\) for uplink transmission from the two antenna panels CMAX,P :

[0156] Method 1: Divide the terminal maximum transmit power \(P\) equally CMAX to obtain the respective panel maximum transmit power \(P\) for uplink transmission from the first antenna panel and the second antenna panel CMAX,P ;

[0157] Method 2: Allocate the terminal maximum transmit power \(P\) according to the power allocation factor CMAX to obtain the respective panel maximum transmit power \(P\) for uplink transmission from the first antenna panel and the second antenna panel CMAX,P ; where the power allocation factor is predefined, or the power allocation factor is configured by the network device, or the power allocation factor is reported by the terminal device;

[0158] Method 3: Determine the respective panel maximum transmit power \(P\) for uplink transmission from the first antenna panel and the second antenna panel according to the indication information CMAX,P The indication information is used to indicate the panel maximum transmit power \(P\) of each of the two antenna panels CMAX,P .

[0159] For non-overlapping symbols, the above Method 1, Method 2, and Method 3 can be used to determine the maximum panel transmit power of the panel for each symbol respectively. Alternatively, the maximum terminal transmit power can be directly determined as the maximum panel transmit power of the panel for non-overlapping symbols.

[0160] That is, for the first uplink transmission on the first non-overlapping symbol, one of the following methods is used to determine the first maximum panel transmit power P corresponding to the first uplink transmission from the first antenna panel CMAX,P1 :

[0161] Method 1: Divide the maximum terminal transmit power P CMAX to obtain the first maximum panel transmit power P corresponding to the first uplink transmission from the first antenna panel CMAX,P1 ;

[0162] Method 2: Allocate the maximum terminal transmit power P according to the power allocation factor CMAX to obtain the first maximum panel transmit power P corresponding to the first uplink transmission from the first antenna panel CMAX,P1 ; where the power allocation factor is predefined, or the power allocation factor is configured by the network device, or the power allocation factor is reported by the terminal device;

[0163] Method 3: Determine the first maximum panel transmit power P corresponding to the first uplink transmission from the first antenna panel according to the indication information CMAX,P1 , where the indication information is used to indicate the maximum panel transmit power P of each of the two antenna panels CMAX,P ;

[0164] Method 4: Determine the maximum terminal transmit power P CMAX as the first maximum panel transmit power P corresponding to the first uplink transmission from the first antenna panel CMAX,P1 .

[0165] For the second uplink transmission on the second non-overlapping symbol, one of the following methods is used to determine the second maximum panel transmit power P corresponding to the second uplink transmission from the second antenna panel CMAX,P2 :

[0166] Method 1: Divide the maximum terminal transmit power P CMAX to obtain the second maximum panel transmit power P corresponding to the second uplink transmission from the second antenna panel CMAX,P2 ;

[0167] Method 2: Allocate the maximum terminal transmit power P according to the power allocation factor CMAX to obtain the second maximum panel transmit power P corresponding to the second uplink transmission from the second antenna panel CMAX,P2; wherein, the power allocation factor is predefined, or the power allocation factor is configured by the network device, or the power allocation factor is reported by the terminal device;

[0168] Method 3: Determine the maximum transmit power P of the second panel corresponding to the second uplink transmission from the second antenna panel according to the indication information CMAX,P2 , and the indication information is used to indicate the maximum transmit power P of each of the two antenna panels CMAX,P ;

[0169] Method 4: Determine the maximum transmit power P of the terminal as the maximum transmit power P of the second panel corresponding to the second uplink transmission from the second antenna panel CMAX CMAX,P2 .

[0170] II. The configuration information of the maximum transmit power includes: the configuration information of the maximum transmit power P of each of the first panel and the second panel CMAX,P .

[0171] Exemplarily, the two antenna panels include a first antenna panel and a second antenna panel; the configuration information of the maximum transmit power includes: the configuration information of the first maximum transmit power P of the first antenna panel CMAX,P1 and the configuration information of the second maximum transmit power P of the second antenna panel CMAX,P2 .

[0172] In a possible implementation, one of the following methods can be used to determine the maximum transmit power P corresponding to each of the at most two antenna panels of the terminal device for uplink transmission respectively CMAX,P .

[0173] Method 5: The maximum transmit power P of the first panel for the first uplink transmission CMAX,P is the first maximum transmit power P CMAX,P1 ; the maximum transmit power P of the second panel for the second uplink transmission CMAX,P is the second maximum transmit power P CMAX,P2 .

[0174] In the case where the access network device configures the maximum transmit power for each panel, the power control of each panel is performed according to the maximum transmit power of the corresponding panel.

[0175] Exemplarily, determine the maximum transmit power P of the first panel for each symbol (including overlapping symbols and non-overlapping symbols) in the first transmission opportunity of the first panel CMAX,P as the first maximum transmit power P CMAX,P1; Determine the maximum transmit power P of the second panel for each symbol (including overlapping and non-overlapping symbols) during the second transmission opportunity CMAX,P as the maximum transmit power P of the second panel CMAX,P2 .

[0176] III. The configuration information of the maximum transmit power includes: the configuration information of the maximum transmit power P of the terminal device CMAX , and the configuration information of the maximum transmit power P of each corresponding panel of the first panel and the second panel CMAX,P .

[0177] That is, the two antenna panels include the first antenna panel and the second antenna panel; the configuration information of the maximum transmit power includes: the configuration information of the maximum transmit power P of the terminal device CMAX , and the configuration information of the maximum transmit power P of the first panel of the first antenna panel CMAX,P1 and the configuration information of the maximum transmit power P of the second panel of the second antenna panel CMAX,P2 .

[0178] The first antenna panel is used for the first uplink transmission during the first transmission opportunity, and the second antenna panel is used for the second uplink transmission during the second transmission opportunity. There are overlapping symbols between the first transmission opportunity and the second transmission opportunity within the transmission time slot.

[0179] Optionally, the first transmission opportunity further includes first non-overlapping symbols that do not overlap with the second transmission opportunity within the transmission time slot.

[0180] Optionally, the second transmission opportunity further includes second non-overlapping symbols that do not overlap with the first transmission opportunity within the transmission time slot.

[0181] Since the maximum transmit power of the terminal device for each symbol shall not exceed P CMAX ; For the size relationship between P CMAX and P CMAX,P1 +P CMAX,P2 , the following several methods are provided to determine the maximum transmit power of each panel:

[0182] Method 6: When the maximum transmit power P of the terminal CMAX is greater than the sum of the maximum transmit power P of the first panel CMAX,P1 and the maximum transmit power P of the second panel CMAX,P2 , the maximum transmit power P of the panel for the first uplink transmission from the first antenna panel CMAX,P is the maximum transmit power P of the first panel CMAX,P1 , and the maximum transmit power P of the panel for the second uplink transmission from the second antenna panel CMAX,P is the maximum transmit power P of the second panel CMAX,P2 .

[0183] That is, when P CMAX > P CMAX,P1 + P CMAX,P2 , the maximum transmit power of each panel can be power-controlled according to the P CMAX,P configured for each panel.

[0184] Method 7: When the maximum transmit power P CMAX of the terminal is less than or equal to the sum of the maximum transmit power P CMAX,P1 of the first panel and the maximum transmit power P CMAX,P2 of the second panel, the maximum transmit power P CMAX,P of the first antenna panel for the first uplink transmission on the overlapping symbols is half of the maximum transmit power P CMAX,P1 of the first panel, and the maximum transmit power P CMAX,P of the second antenna panel for the second uplink transmission on the overlapping symbols is half of the maximum transmit power P CMAX,P2 of the second panel.

[0185] That is, when P CMAX ≤ P CMAX,P1 + P CMAX,P2 , on the overlapping symbols, the maximum transmit power of each panel is reduced to 1 / 2 of the configured value, that is, 1 / 2 * P CMAX,P .

[0186] For example, the maximum transmit power P CMAX configured by the access network device for the terminal device is 26 dbm, the maximum transmit power P CMAX,P1 of the first panel of the first panel is 26 dbm, and the maximum transmit power P CMAX,P2 of the second panel of the second panel is 26 dbm; then 26 dbm ≤ 26 dbm + 26 dbm; then the maximum transmit power of the first panel is 1 / 2 * the maximum transmit power P CMAX,P1 : 1 / 2 * 26 dbm = 23 dbm; the maximum transmit power of the second panel is 1 / 2 * the maximum transmit power P CMAX,P2 : 1 / 2 * 26 dbm = 23 dbm.

[0187] Exemplarily, when P CMAX ≤ P CMAX,P1 + P CMAX,P2 , if the transmission capabilities of the first panel and the second panel are the same, then the maximum transmit power P CMAX,P of the first antenna panel for the first uplink transmission on the overlapping symbols is 1 / 2 * P CMAX,P1, the maximum transmit power P of the second uplink transmission on the overlapping symbols from the second antenna panel CMAX,P is 1 / 2*P CMAX,P2 . Among them, the same transmission capacity can be that the capabilities of the two power amplifiers (PAs) corresponding to the two panels are the same.

[0188] Method 8: When the maximum transmit power P CMAX of the terminal is less than or equal to the sum of the maximum transmit power P CMAX,P1 of the first panel and the maximum transmit power P CMAX,P2 of the second panel, the maximum transmit power P CMAX,P of the first uplink transmission on the overlapping symbols from the first antenna panel is the maximum transmit power P CMAX,P1 of the first panel divided by the first ability coefficient, and the maximum transmit power P CMAX,P of the second uplink transmission on the overlapping symbols from the second antenna panel is the maximum transmit power P CMAX,P2 of the second panel divided by the second ability coefficient; among them, the first ability coefficient is determined according to the transmission capacity of the first antenna panel, and the second ability coefficient is determined according to the transmission capacity of the second antenna panel.

[0189] That is, when P CMAX ≤P CMAX,P1 +P CMAX,P2 , then on the overlapping symbols, the maximum transmit power of each panel is reverted to 1 / B of the configured value, that is, 1 / B*P CMAX,P , and B is the ability coefficient determined according to the transmission capacity of each panel.

[0190] For example, the maximum transmit power P CMAX configured by the access network device for the terminal device is 26 dbm, the maximum transmit power P CMAX,P1 of the first panel of the first panel is 26 dbm, and the maximum transmit power P CMAX,P2 of the second panel of the second panel is 26 dbm; then 26 dbm ≤ 26 dbm + 26 dbm; among them, the first ability coefficient of the first panel is 2, and the second ability coefficient of the second panel is 4; then the maximum transmit power of the first panel is 1 / 2 * the maximum transmit power P CMAX,P1 : 1 / 2 * 26 dbm = 23 dbm; the maximum transmit power of the second panel is 1 / 4 * the maximum transmit power P CMAX,P2 : 1 / 4 * 26 dbm = 20 dbm.

[0191] Exemplarily, when P CMAX ≤P CMAX,P1 +P CMAX,P2When the transmission capabilities of the first panel and the second panel are different, the maximum transmit power P of the panel for the first uplink transmission on the overlapping symbols from the first antenna panel CMAX,P is P CMAX,P1 / B1, and the maximum transmit power P of the panel for the second uplink transmission on the overlapping symbols from the second antenna panel CMAX,P is P CMAX,P2 / B2; where B1 is determined according to the transmission capability of the first antenna panel, and B2 is determined according to the transmission capability of the second antenna panel. Exemplarily, the stronger the transmission capability of the panel, the smaller its capability coefficient. Among them, the different transmission capabilities may be the capabilities of two power amplifiers (PAs) corresponding to the two panels.

[0192] Method Nine: When the maximum transmit power P CMAX of the terminal is less than or equal to the sum of the maximum transmit power P CMAX,P1 of the first panel and the maximum transmit power P CMAX,P2 of the second panel, the maximum transmit power P CMAX,P of the panel for the first uplink transmission on the first non-overlapping symbols from the first antenna panel is the maximum transmit power P CMAX,P1 of the first panel. When the maximum transmit power P CMAX of the terminal is less than or equal to the sum of the maximum transmit power P CMAX,P1 of the first panel and the maximum transmit power P CMAX,P2 of the second panel, the maximum transmit power P CMAX,P of the panel for the second uplink transmission on the second non-overlapping symbols from the second antenna panel is the maximum transmit power P CMAX,P1 of the second panel.

[0193] That is, when P CMAX ≤P CMAX,P1 +P CMAX,P2 , then on the overlapping symbols, the maximum transmit power of each panel can be power-controlled according to the configured P CMAX,P of each panel.

[0194] It should be noted that the description of the foregoing maximum transmit power configuration information can also be applied to the embodiments executed by the terminal device as described in step 210; it can also be applied to the embodiments executed by the access network device as described in step 220; this application will not repeat it here.

[0200] The configuration information of the maximum transmit power is used to determine, when scheduling simultaneous uplink transmission of multiple antenna panels (STxMP) through multiple downlink control information (DCI), the second panel maximum transmit power P for uplink transmission from the second antenna panel CMAX,P2 。
