[0037] First, let's explain the application scenarios of this application:

[0038] Figure 1 A block diagram of a communication system provided in an exemplary embodiment of this application is shown. The communication system may include a terminal 10 and a network device 20.

[0039] The number of terminals 10 is typically multiple, and one or more terminals 10 can be distributed within the cell managed by each network device 20. Terminals 10 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), etc. For ease of description, in this embodiment, the devices mentioned above are collectively referred to as terminals.

[0040] Network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal 10. For ease of description, in this embodiment, the aforementioned device providing wireless communication functionality to terminal 10 is collectively referred to as a network device. Network device 20 and terminal 10 can establish a connection via an air interface, thereby enabling communication, including signaling and data exchange. There can be multiple network devices 20, and two adjacent network devices 20 can communicate via wired or wireless means. Terminal 10 can transmit beam reports between different network devices 20, that is, establish connections with different network devices 20.

[0041] The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with network equipment functions may differ; for example, in a 5G NR (New Radio) system, it is called gNodeB or gNB. As communication technologies evolve, the name "network device" may change.

[0042] Optionally, network device 20 may have at least two TRPs configured; or at least two network devices 20 may each have at least one TRP configured, meaning at least two network devices 20 may have at least two TRPs configured. In other words, the at least two TRPs may come from the same cell or different cells.

[0043] In some embodiments, the network device 20 is configured with four TRPs and can provide services to the terminal 10 through the four TRPs, so that the terminal can transmit data based on the four TRPs.

[0044] For example, if network device 20 is configured with two TRPs, namely TRP1 and TRP2, see [link to relevant documentation]. Figure 2 and Figure 3 This is a scheme in which the terminal transmits uplink data to two TRPs at the same time. That is, the terminal can transmit uplink data to TRP1 and TRP2 at the same time.

[0045] Optionally, see Figure 2 The terminal uses a DCI to schedule the same PUSCH to send data to TRP1 and TRP2 through two panels. See also Figure 3 The terminal sends data from panel 1 to TRP1 via PUSCH 1, which is scheduled by DCI 1, and sends data from panel 2 to TRP2 via PUSCH 2, which is scheduled by DCI 2.

[0046] Specifically, when the terminal transmits uplink data to the TRP, it also determines the uplink transmit power based on the open-loop power control parameters and the closed-loop power control parameters, so as to transmit uplink data to each TRP according to the determined uplink transmit power.

[0047] For example, taking the power control of PUSCH (Physical Uplink Shared Channel) as an example, this section explains how to determine the transmission power of PUSCH. The following formula is used to determine the transmission power of PUSCH, but it must not exceed the transmit power limit:

[0048] P = P0 + α × PL + f(l) + Δ

[0049] Where f(l) is the power control adjustment state value, also known as the closed-loop power control parameter. Its value is f(l) = δ(l) or f(l, i) = f(i - i0, l) + ∑δ, specifically calculated according to higher-layer parameters. Here, δ is the value indicated by the DCI (Downlink Control Information) through the TPC (Transmission Power Control) field. l is called the closed-loop power index, i is time representing the current moment, P0 is the open-loop receiver power target value (the desired received power configured in the network equipment), α is a partial path loss compensation factor, PL is the estimated downlink path loss, and Δ represents other adjustment quantities.

[0050] Optionally, f(i, l, t) = f(i - i0, l, t) + ∑δ, where t is the identifier of the TRP, δ is the closed-loop power adjustment value indicated by the TPC command, i is the time, used to represent the current moment, and f(i, l, t) is the accumulated closed-loop power adjustment value of each TRP.

[0051] The "5G NR system" in this application embodiment can also be referred to as a 5G system or an NR system, but those skilled in the art will understand its meaning. The technical solutions described in this application embodiment can be applied to 5G NR systems, as well as subsequent evolution systems of 5G NR systems.

[0052] Figure 4 The flowchart illustrates a power determination method provided in an exemplary embodiment of this application, which can be applied, for example, to... Figure 1 In the terminal and network device shown, the method includes at least some of the following:

[0053] Step 401: The network device sends power control information. The power control information is used to indicate the power control parameter set of each panel among multiple panels. The power control parameter set is used by the terminal to determine the transmission power of the panel. Multiple panels support uplink transmission at the same time according to the corresponding transmission power.

[0054] This panel is used by the terminal for uplink or downlink transmission. The panel can be understood as a set of antennas that can form directional signals through beamforming, transmitting information to the TRP in a specific beam direction. Each panel can only transmit signals in one beam direction at a time. In some embodiments, the panel may also be called an antenna panel, a beam used for uplink transmission, a transmission identifier, or other names; this application embodiment does not limit the specific name. The transmission identifier is used to indicate the different modules used for transmission configured in the terminal.

[0055] The same time refers to the time domain resources of multiple panels transmitting uplinks completely overlapping, or the time domain resources of multiple panels transmitting uplinks partially overlapping.

[0056] This multi-panel architecture supports simultaneous uplink transmission from multiple panels, which can also be understood as the terminal supporting simultaneous uplink transmission from multiple panels to multiple TRPs. In other words, the terminal can simultaneously determine the transmit power used for uplink transmission from multiple panels, so as to perform uplink transmission according to the determined transmit power.

[0057] In some embodiments, the power control information is carried in DCI, MAC CE, or RRC, and this application does not limit the scope of the embodiments.

[0058] In some embodiments, the power control parameter information set includes at least one of the following:

[0059] (1) Closed-loop power index.

[0060] (2) Target power value of open-loop receiver.

[0061] (3) Partial road loss compensation factor.

[0062] (4) Downstream road loss estimate.

[0063] In this embodiment, the parameters are the same as those in the above embodiments, and will not be repeated here.

[0064] Step 402: The terminal receives power control information.

[0065] In the solution provided in this application embodiment, the network device sends power control information to the terminal to indicate the power control parameter set of each of the multiple panels, so that the terminal can determine the transmission power of the corresponding panel based on the multiple power control parameter sets.

[0066] Step 403: The terminal determines the transmit power for each panel to perform uplink transmission based on the power control information.

[0067] The power control information received by the terminal includes a set of power control parameters for each antenna panel. This set of power control parameters is used by the terminal to determine the transmit power of the corresponding antenna panel. Therefore, the terminal can determine the transmit power used for uplink transmission based on the received power control information.

[0068] It should be noted that the steps performed by the terminal in the embodiments of this application can form a new embodiment on their own, and the steps performed by the network device can also form a new embodiment on their own. The embodiments of this application are not limited.

[0069] The solution provided in this application embodiment provides that when a terminal performs uplink transmission through multiple panels, the transmit power of each antenna panel can be determined based on the power control parameter set of each panel, and then the transmit power of each panel for uplink transmission can be determined according to the determined transmit power, so as to support multiple panels to perform uplink transmission at appropriate transmit power at the same time, thereby improving the transmission throughput and avoiding significant interference to other transmissions.

[0070] In some embodiments, see Figure 5 The process by which the terminal determines the uplink transmission power for each panel based on power control information includes the following steps:

[0071] Step 501: The terminal determines the first transmit power of each panel based on the power control information.

[0072] In this embodiment, the power control information is sent by the network device, or it can be understood as the power control information being indicated by the network device. In some embodiments, the first transmit power of each panel determined by the terminal based on the power control information actually refers to the transmit power that the network device expects the terminal to use when making uplink transmissions through each panel.

[0073] In some embodiments, the first transmit power is determined using the following formula:

[0074] P = P0 + α × PL + f(l) + Δ

[0075] Where P is the first transmit power of the panel, f(l) is the power control adjustment state value, also known as the closed-loop power control parameter. Its value is f(l) = δ(l) or f(l, i) = f(i - i0, l) + ∑δ, the specific calculation method being indicated by higher-layer parameters, where δ is the value indicated by the DCI (Downlink Control Information) through the TPC field. l is called the closed-loop power index, i is time, representing the current moment, P0 is the open-loop receiver power target value, which is the expected receive power configured in the network equipment, α is a partial path loss compensation factor, PL is the estimated downlink path loss, and Δ is other adjustment quantities.

[0076] Step 502: The terminal determines the uplink transmission power of each panel based on the first transmission power of each panel and the power limit.

[0077] The power limit refers to the limitation on the transmission power of the terminal itself. The terminal sets this power limit to ensure that the transmission power of each panel for uplink transmission does not exceed the power limit.

[0078] Optionally, the power limit may be agreed upon by the communication protocol, specified at the time of manufacture of the terminal, set by the terminal, or set in other ways; this application embodiment does not impose any limitations.

[0079] In some embodiments, the power limit refers to a first power limit defined for each panel, or it can be understood that each panel has a corresponding first power limit. After determining the first transmit power of the panel, the terminal needs to compare the first transmit power of the panel with the first power limit to determine the actual transmit power of the panel for uplink transmission.

[0080] In some embodiments, the power limit refers to the total power limit defined for the terminal. After determining the first transmit power of each panel, the terminal needs to compare the sum of the first transmit powers of all panels with the total power limit, and then the terminal determines the transmit power for uplink transmission using the panels.

[0081] In some embodiments, the power limit includes a first power limit defined for each panel and a total power limit defined for the terminal. The terminal needs to compare not only the first transmit power of the panel with the first power limit, but also the sum of the first transmit powers of all panels with the sum of the first power limits, so that the terminal can determine the transmit power for uplink transmission using the panel.

[0082] Next, the terminal determines the uplink transmission power of each panel based on the first transmission power and power limit of each panel, including any of the following methods.

[0083] The first method: The minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0084] In this embodiment of the application, each panel of the terminal has a first transmission power and a first power limit. If the first transmission power is greater than the first power limit, the terminal cannot provide the required first transmission power. If the first transmission power is less than the first power limit, the terminal does not need to work according to the first power limit. Therefore, the terminal determines the transmission power for uplink transmission of each panel by the minimum transmission power between the first transmission power of each panel and the power limit corresponding to each panel.

[0085] For example, if the first transmit power of the panel is less than the first power limit, then the first transmit power of the panel is determined as the transmit power for uplink transmission of the panel; if the first transmit power of the panel is greater than the first power limit, then the first power limit of the panel is determined as the transmit power for uplink transmission of the panel.

[0086] The second method is to determine the first transmit power of each panel as the transmit power for uplink transmission of each panel.

[0087] The third method: Determine the uplink transmission power of each panel based on the ratio of the first transmission power of multiple panels and the total power limit.

[0088] In this case, each of the multiple panels has a corresponding first transmit power, and the terminal also has a total power limit. At this time, the total power limit is divided according to the ratio of the first transmit powers of the multiple panels, so as to obtain the transmit power of each of the multiple panels for uplink transmission.

[0089] The third method for determining the uplink transmission power of each panel can also be understood as follows: for each panel among multiple panels, obtain the proportion of the first transmission power of that panel to the sum of the first transmission powers of all panels, and determine the uplink transmission power of that panel by multiplying the obtained proportion of the panel by the total power limit.

[0090] For example, if the panel includes panel 1 and panel 2, the first transmission power of panel 1 is P1, the first transmission power of panel 2 is P2, and the total power is limited to P... cmax Then the transmit power P of panel 1 for uplink transmission panel1 =P1*P cmax / (P1+P2), Ppanel2=P2*Pcmax / (P1+P2).

[0091] The fourth method is to determine the transmission power of the panel with higher priority according to the priority order, which is the minimum value between the first transmission power and the first power limit of the panel, and to back down the transmission power of the panel with lower priority, so that the sum of the transmission power determined by multiple panels does not exceed the total power limit.

[0092] In this embodiment of the application, each panel has a priority. The terminal sorts the panels according to their priority, prioritizing the transmission power of the panels with higher priority. For panels with lower priority, if the terminal cannot meet the total transmission power limit, the transmission power of the panels with lower priority will be rolled back.

[0093] In some embodiments, for the first panel with the highest priority among all panels, the minimum of the first panel's first transmit power and the first power limit is determined as the transmit power for the first panel to perform uplink transmission. For the remaining panels other than the first panel, power back-off is performed on the remaining panels so that the sum of the determined transmit power for the first panel to perform uplink transmission and the back-off transmit power of the remaining panels does not exceed a total power threshold.

[0094] The following explains how to determine the priority of a panel.

[0095] In some embodiments, the terminal determines the priority of each panel by acquiring the channel measurement results of each panel. Optionally, the priority of each panel is proportional to the channel measurement results. This can also be understood as the higher the quality of the channel measurement results of a panel, the higher the priority of that panel.

[0096] Optionally, the channel measurement results may include RSRQ (Reference Signal Receiving Quality), signal-to-noise ratio, or other parameters, which are not limited in the embodiments of this application.

[0097] In other embodiments, the terminal determines the priority of each panel based on the type of service processed by each panel. For example, the service type may include at least one of eMBB (Enhanced Mobile Broadband) and URLLC (Ultra-Reliable Low Latency Communication). A panel transmitting eMBB may have a higher priority than a panel transmitting URLLC, or vice versa.

[0098] In other embodiments, the terminal determines the priority of each panel based on its channel type. For example, the channel type includes at least one of CG (Configured Grant) PUSCH (Physical Uplink Shared Channel) and DG (Dynamic Grant) PUSCH. A panel transmitting CG PUSCH has a higher priority than a panel transmitting DG PUSCH, or vice versa.

[0099] In other embodiments, the terminal determines the priority of each panel by the timing of the channels transmitted by each panel. Optionally, the earlier the transmission time of the channel, the higher the priority of the panel corresponding to that channel.

[0100] Each of the four methods for determining the uplink transmission power of the panel has its own execution conditions, which are explained below.

[0101] In some embodiments, the power limit is a first power limit for each panel, and in this case, there are two conditions for performing the first method described above.

[0102] Optionally, if multiple panels transmit PUSCHs scheduled by a single DCI (Downlink Control Information), the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0103] Optionally, if multiple panels transmit PUSCHs with multi-DCI scheduling, the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0104] For example, multiple panels include panel 1 and panel 2, with the transmit power of panel 1 being Ppanel1 and the transmit power of panel 2 being Ppanel2. Ppanel1 = min{Pcmax1, P1}; Ppanel2 = min{Pcmax2, P2}, where Pcmax1 is the first power limit of panel 1 and Pcmax2 is the first power limit of panel 2.

[0105] In some embodiments, the power limit is a total power limit, and in this case, there are multiple conditions to perform any of the above methods.

[0106] Optionally, multiple panels transmit PUSCHs with a single DCI schedule. If the sum of the first transmit power of each panel is not greater than the total power limit, the first transmit power of each panel is determined as the transmit power for uplink transmission of each panel.

[0107] For example, taking two panels as an example, if P1 + P2 <= Pcmax, then the transmission power Ppanel1 = P1 and Ppanel2 = P2.

[0108] In some embodiments, if the sum of the first transmit powers of multiple panels is greater than the total power limit, the transmit power for uplink transmission of each panel is determined according to the ratio of the first transmit powers of the multiple panels and the total power limit.

[0109] It should be noted that multiple panels send multiple DCI-scheduled PUSCHs, and if the sum of the first transmit powers of multiple panels is greater than the total power limit, the transmit power of each panel for uplink transmission is determined according to the ratio of the first transmit powers of multiple panels and the total power limit.

[0110] For example, taking two panels as an example, if P1 + P2 > Pcmax, the power is allocated between the two panels according to the power ratio. Ppanel1 = P1 * Pcmax / (P1 + P2), Ppanel2 = P2 * Pcmax / (P1 + P2).

[0111] Optionally, if the time domain resources occupied by multiple DCI-scheduled PUSCHs sent by multiple panels overlap, and the terminal supports changing the transmit power at a transmission time, for the non-overlapping parts, the minimum transmit power between the first transmit power of each panel and the total power limit corresponding to each panel shall be determined as the transmit power for each panel to perform uplink transmission.

[0112] For example, such as Figure 6 As shown, the PUSCH in TRP1 and the PUSCH in TRP2 have overlapping parts, and there are also non-overlapping parts. Taking two panels as an example, for the non-overlapping parts, Ppanel1 = min{Pcmax, P1} or Ppanel2 = min{Pcmax, P2}.

[0113] Optionally, if it is determined that the time domain resources occupied by the multiple panels overlap, the multiple panels transmit PUSCHs with multiple DCI scheduling, and the terminal supports changing the transmit power at a transmission time, for the overlapping part, if the sum of the first transmit powers of the multiple panels is greater than the total power limit, the transmit power of each panel for uplink transmission is determined according to the ratio of the first transmit powers of the multiple panels and the total power limit.

[0114] For example, taking two panels as an example, the terminal's multiple panels transmit PUSCH using multi-DCI scheduling and support changing the transmit power during a single transmission. For the overlapping portion, if P1+P2>Pcmax, the power is allocated between the two panels according to the power ratio. Ppanel1=P1*Pcmax / (P1+P2), Ppanel2=P2*Pcmax / (P1+P2).

[0115] Optionally, if it is determined that the time domain resources occupied by the multiple panels overlap, the multiple panels send PUSCHs with multiple DCI scheduling, and the terminal supports changing the transmit power at a transmission time, for the overlapping part, if the sum of the first transmit power of each panel is not greater than the total power limit, the first transmit power of each panel is determined as the transmit power for each panel to perform uplink transmission.

[0116] For example, taking two panels as an example, the terminal sends PUSCH with multiple DCI scheduling and supports changing the transmit power at one transmission time. For the overlapping part, if P1+P2<=Pcmax, the transmit power of each panel is Ppanel1=P1 and Ppanel2=P2.

[0117] Optionally, if the sum of the first transmit power of each panel is greater than the total power limit, the transmit power of the panel with higher priority is determined as the minimum of the first transmit power of the panel and the first power limit, according to the priority order of the panels, and the transmit power of the panel with lower priority is backed up so that the sum of the transmit power determined by multiple panels is not greater than the total power limit.

[0118] Furthermore, if it is determined that the time domain resources occupied by multiple panels overlap, the multiple panels transmit PUSCHs with multiple DCI scheduling, and the terminal supports changing the transmit power at a transmission time, for the overlapping part, if the sum of the first transmit power of each panel is greater than the total power limit, the transmit power of the panel with higher priority is determined according to the priority order of the panels as the minimum value between the first transmit power of the panel and the first power limit, and the transmit power of the panel with lower priority is backed up so that the sum of the transmit power determined by multiple panels is not greater than the total power limit.

[0119] For example, let's illustrate this by having two panels send DG PUSCH and CG PUSCH respectively. See [link / reference] Figure 7TRP 1 transmits the CG PUSCH, and TRP 2 transmits the DG PUSCH. Multiple panels on the terminal transmit PUSCH using multi-DCI scheduling, and the transmit power can be changed during a single transmission. For overlapping portions, the transmit power of the DG PUSCH is prioritized. The CG PUSCH is transmitted by Ppanel1, and the DG PUSCH is transmitted by Ppanel2, i.e., Ppanel2 = min{Pcmax, P2}. If P2 <= Pcmax, then Ppanel1 = P1 - X, where X ≥ P1 + P2 - Pcmax. If P2 > Pcmax, then P1 = 0.

[0120] Optionally, if the terminal does not support changing the transmit power at a transmission time, multiple panels transmit PUSCHs with multi-DCI scheduling, and it is determined that multiple panels are performing uplink transmission, if the sum of the first transmit powers of multiple panels is greater than the total power limit, the transmit power of each panel for uplink transmission is determined according to the ratio of the first transmit powers of multiple panels and the total power limit.

[0121] For example, taking two panels as an example, the terminal does not support changing the transmit power at one transmission time, multiple panels send PUSCH with multiple DCI scheduling, and it is determined that multiple panels are performing uplink transmission. If P1+P2>Pcmax, the power is allocated between the two panels according to the power ratio, Ppanel1=P1*Pcmax / (P1+P2), Ppanel2=P2*Pcmax / (P1+P2).

[0122] Optionally, if the terminal does not support changing the transmit power at a transmission time, and the multiple panels send PUSCHs with multi-DCI scheduling, and the sum of the first transmit power of each panel is not greater than the total power limit, then the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel shall be determined as the transmit power for each panel to perform uplink transmission.

[0123] For example, taking two panels as an example, the terminal does not support changing the transmit power at one transmission time, multiple panels send PUSCH with multiple DCI scheduling, and it is determined that there are multiple panels performing uplink transmission. If P1+P2<=Pcmax, the transmit power of each panel is Ppanel1=min{Pcmax1,P1}, Ppanel2=min{Pcmax2,P2}.

[0124] In some embodiments, if the sum of the first transmit powers of each panel is not greater than the total power limit, the first transmit power of each panel is determined as the transmit power for uplink transmission of each panel.

[0125] Optionally, if the sum of the first transmit power of each panel is greater than the total power limit, the transmit power of the panel with higher priority is determined as the minimum of the first transmit power of the panel and the total power limit, according to the priority order of the panels, and the transmit power of the panel with lower priority is backed up so that the sum of the transmit power determined by multiple panels is not greater than the total power limit.

[0126] Furthermore, when the terminal does not support changing the transmit power during a transmission, multiple panels transmit PUSCHs with multi-DCI scheduling, and it can be determined that multiple panels are simultaneously performing uplink transmission, if the sum of the first transmit powers of each panel is greater than the total power limit, the transmit power of the panel with higher priority is determined as the minimum value between the panel's first transmit power and the total power limit, according to the priority order of the panels, and the transmit power of the panel with lower priority is backed up so that the sum of the transmit powers determined by multiple panels is not greater than the total power limit.

[0127] For example, let's illustrate this by having two panels send DG PUSCH and CG PUSCH respectively. See [link / reference] Figure 7 TRP 1 transmits CG PUSCH, TRP 2 transmits DG PUSCH. Multiple panels of the terminal transmit PUSCH using multi-DCI scheduling, and do not support changing the transmit power during a single transmission. If Ppanel1 + Ppanel2 > Pcmax, the transmit power of DG PUSCH is prioritized, while CG PUSCH is transmitted by Ppanel1. Ppanel2 = min{Pcmax, P2}. If P2 <= Pcmax, then Ppanel1 = P1 - X, where X ≥ P1 + P2 - Pcmax. If P2 > Pcmax, then P1 = 0. Optionally, when the terminal does not support changing the transmit power during a single transmission, multiple panels transmit PUSCH using multi-DCI scheduling, and it cannot be determined whether multiple panels are performing uplink transmission, the transmit power of the panel with higher priority is determined according to the panel priority order as the minimum value between the panel's first transmit power and the first power limit. The transmit power of the panel with lower priority is backed up so that the sum of the determined transmit powers of multiple panels does not exceed the total power limit.

[0128] For example, let's illustrate this by having two panels send DG PUSCH and CG PUSCH respectively. See [link / reference] Figure 7TRP 1 transmits the CG PUSCH, and TRP 2 transmits the DG PUSCH. Multiple panels on the terminal transmit PUSCH using multi-DCI scheduling. Changing the transmit power during a single transmission and the presence of multiple panels performing uplink transmissions cannot be guaranteed. Priority is given to ensuring the transmit power of the DG PUSCH. The CG PUSCH is transmitted by Ppanel1, and the DG PUSCH is transmitted by Ppanel2. The transmit power of DG is Ppanel2 = min{Pcmax, P2}. If P2 <= Pcmax, then Ppanel1 = P1 - X, where X ≥ P1 + P2 - Pcmax. If P2 > Pcmax, then P1 = 0.

[0129] Optionally, multiple panels transmit PUSCHs with a single DCI scheduling, and the sum of the first transmit power of each panel is not greater than the total power limit. According to the priority order of the panels, the transmit power of the panel with higher priority is determined as the minimum value between the first transmit power of the panel and the first power limit. The transmit power of the panel with lower priority is backed up so that the sum of the transmit power determined by multiple panels is not greater than the total power limit.

[0130] For example, panel2 has a higher L1-RSRP, making it a higher priority panel. Ppanel2 = min{Pcmax, P2}. If P2 <= Pcmax, then Ppanel1 = P1 - X, where X ≥ P1 + P2 - Pcmax. If P2 > Pcmax, then P1 = 0.

[0131] In some embodiments, the power limit includes a first power limit and a total power limit. In this case, there are multiple conditions to perform any of the above methods.

[0132] Optionally, if the sum of the first power limits of each panel is not greater than the total power limit, the minimum transmit power among the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0133] For example, taking two panels as an example, Pcmax1 + Pcmax2 <= Pcmax, Ppanel1 = min{Pcmax, P1} or Ppanel2 = min{Pcmax, P2}.

[0134] It should be noted that, regardless of whether multiple panels send a single DCI-scheduled PUSCH or multiple DCI-scheduled PUSCHs, when the above conditions are met, the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0135] Optionally, if the sum of the first power limit of each antenna panel is greater than the total power limit, and the PUSCH transmitted by the multiple panels is scheduled by a single DCI, the minimum value between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for each panel to perform uplink transmission.

[0136] Optionally, if the sum of the first power limit of each panel is greater than the total power limit, the sum of the first transmit power of each panel is not greater than the total power limit, and the PUSCH transmitted by the multiple panels is scheduled by a single DCI, the first transmit power of each panel is determined as the transmit power for each panel to perform uplink transmission.

[0137] For example, taking two panels as an example, if the PUSCH transmitted by the two panels is a PUSCH scheduled by a single DCI, and Pcmax1+Pcmax2>Pcmax, Ppanel1+Ppanel2<Pcmax, then Ppanel1=min{Pcmax1, P1}, Ppanel2=min{Pcmax2, P2}.

[0138] Optionally, if the sum of the first power limit of each antenna panel is greater than the total power limit, the sum of the first transmit power of each panel is greater than the total power limit, and the PUSCH transmitted by the multiple panels is scheduled by a single DCI, the transmit power for each panel to perform uplink transmission is determined according to the ratio of the first transmit powers of the multiple panels and the sum of the first transmit powers of the multiple panels.

[0139] For example, taking two panels as an example, if the PUSCH transmitted by the two panels is a PUSCH scheduled by a single DCI, Pcmax1+Pcmax2>Pcmax, Ppanel1+Ppanel2>Pcmax, then Ppanel1=P1*Pcmax / (P1+P2), Ppanel2=P2*Pcmax / (P1+P2).

[0140] Optionally, if the sum of the first power limit of each antenna panel is greater than the total power limit, the sum of the first transmit power of each panel is greater than the total power limit, and the PUSCH transmitted by the multiple panels is scheduled by a single DCI, in the order of the priority of the panels, based on the first transmit power of the panels, the transmit power for performing uplink transmission is determined for each panel in sequence, until the sum of the determined transmit powers for uplink transmission of the panels reaches the power limit.

[0141] In the following, description is given with reference to a combined solution of three cases corresponding to the scenario where the sum of the first power limit of each antenna panel is greater than the total power limit.

[0142] Optionally, if the sum of the first power limits of each antenna panel is greater than the total power limit, and multiple panels transmit PUSCH using a single DCI scheduling, then the transmit power of each panel needs to consider both the power limits of each panel and the total power limit. First, assume that the minimum value between the first transmit power of each panel and its corresponding first power limit is determined as the transmit power for uplink transmission of each panel, denoted as the second transmit power of each panel. Then, compare this with the total power limit to determine the final transmit power. If the transmit power of each panel is less than or equal to the total transmit power limit, then the transmit power of each panel is the assumed value; if the transmit power of each panel is greater than the transmit power limit, the transmit power for uplink transmission of each panel is determined according to the ratio of the first transmit powers of multiple panels and the sum of the first transmit powers of multiple panels. Alternatively, according to the priority of the panels, based on the first transmit power of the panels, the transmit power for uplink transmission of each panel is determined sequentially until the sum of the determined transmit powers for uplink transmission of the panels reaches the power limit.

[0143] For example, taking two panels as an example, if the PUSCH transmitted by the two panels is a single DCI-scheduled PUSCH, assume that the transmit power of each panel is Ppanel1 = min{Pcmax1, P1}, Ppanel2 = min{Pcmax2, P2}. Further, if Ppanel1 + Ppanel2 <= Pcmax, then the transmit power of each panel is that value; if Ppanel1 + Ppanel2 > Pcmax, then Ppanel1 = P1 * Pcmax / (P1 + P2), Ppanel2 = P2 * Pcmax / (P1 + P2). Alternatively, if the priority of Ppanel1 is higher than that of Ppanel2, then Ppanel2 = min{Pcmax, P2}; if P2 <= Pcmax, then Ppanel1 = P1 - X, where X ≥ P1 + P2 - Pcmax. If P2 > Pcmax, then P1 = 0.

[0144] Optionally, if the sum of the first power limits of each panel is greater than the total power limit, and multiple panels send PUSCHs with multi-DCI scheduling, the time domain resources occupied by multiple panels overlap, and the terminal supports changing the transmit power at a transmission time, for the non-overlapping parts, the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for each panel to perform uplink transmission.

[0145] For example, taking two panels as an example, the terminal supports changing the transmit power during a transmission. Multiple panels send PUSCHs with multi-DCI scheduling, where Pcmax1 + Pcmax2 > Pcmax. For non-overlapping parts, Ppanel1 = min{Pcmax1, P1} or Ppanel2 = min{Pcmax2, P2}.

[0146] Optionally, if the sum of the first power limits of each panel is greater than the total power limit, the sum of the first transmit powers of the panels is not greater than the total power limit, and multiple panels transmit PUSCHs with multi-DCI scheduling, the time domain resources occupied by multiple panels overlap, and the terminal supports changing the transmit power at a transmission time, for the overlapping part, the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for each panel to perform uplink transmission.

[0147] For example, multiple panels send PUSCHs with multi-DCI scheduling, and the time domain resources occupied by multiple panels overlap. The terminal supports changing the transmit power at a transmission time. For the overlapping part, Pcmax1+Pcmax2>Pcmax, Ppanel1+Ppanel2<=Pcmax, then Ppanel1=min{Pcmax,P1} or Ppanel2=min{Pcmax,P2}.

[0148] Optionally, if it is determined that the time-domain resources occupied by the multiple panels overlap, and if the sum of the first power limits of each panel is greater than the total power limit, and the sum of the first transmit powers of each panel is greater than the total power limit, the terminal supports changing the transmit power at a transmission time, and the multiple panels transmit PUSCHs with multiple DCI scheduling. For the overlapping part, the transmit power of each panel for uplink transmission is determined according to the ratio of the first transmit powers of the multiple panels and the sum of the first transmit powers of the multiple panels.

[0149] For example, multiple panels send PUSCHs with multi-DCI scheduling, and the time domain resources occupied by multiple panels overlap. The terminal supports changing the transmit power at a transmission time. For the overlapping part, Pcmax1+Pcmax2>Pcmax, Ppanel1+Ppanel2>Pcmax, Ppanel1=P1*Pcmax / (P1+P2), Ppanel2=P2*Pcmax / (P1+P2).

[0150] Optionally, if it is determined that the time-domain resources occupied by the multiple panels overlap, and if the sum of the first power limits of each panel is greater than the total power limit, and the sum of the first transmit powers of each panel is greater than the total power limit, the terminal supports changing the transmit power at a transmission time, and the multiple panels transmit PUSCHs with multi-DCI scheduling. For the overlapping part, according to the priority of the panels, based on the first transmit power of the panels, the transmit power for uplink transmission is determined for each panel in turn, until the sum of the determined transmit powers for uplink transmission of the panels reaches the power limit.

[0151] For example, let's illustrate this by having two panels send DG PUSCH and CG PUSCH respectively. See [link / reference] Figure 7 TRP 1 transmits CG PUSCH, TRP 2 transmits DG PUSCH. Multiple panels transmit PUSCHs with multiple DCI scheduling. The time domain resources occupied by multiple panels overlap, and the terminal supports changing the transmit power at a transmission time. For the overlapping part, Pcmax1 + Pcmax2 > Pcmax, Ppanel1 + Ppanel2 > Pcmax. CG PUSCH is transmitted by Ppanel1, and DG PUSCH is transmitted by Ppanel2, that is, Ppanel2 = min{Pcmax2, P2}, Ppanel1 = min{Pcmax - Ppanel2, P1}.

[0152] The following describes a combination of possible solutions for the following scenario: the sum of the first power limits of each panel is greater than the total power limit; the sum of the first transmit powers of each panel is greater than the total power limit; the terminal supports changing the transmit power during a transmission; and the transmit powers of each panel overlap. For the overlapping portion, the transmit power of each panel needs to consider both the power limits of each panel and the total power limit. First, assume that the minimum value between the first transmit power of each panel and its corresponding first power limit is determined as the transmit power for uplink transmission of each panel, denoted as the second transmit power of each panel. Then, compare this with the total power limit to determine the final transmit power. If the transmit power of each panel is less than or equal to the total transmit power limit, the transmit power of each panel is the assumed value; if the transmit power of each panel is greater than the transmit power limit, the transmit power for uplink transmission of each panel is determined according to the ratio of the first transmit powers of multiple panels and the sum of the first transmit powers of multiple panels. Alternatively, based on the priority of the panels, the uplink transmission power is determined for each panel sequentially according to its first transmission power, until the sum of the uplink transmission powers of the determined panels reaches the power limit.

[0153] Optionally, if the sum of the first power limits of each panel is greater than the total power limit, and multiple panels are transmitting PUSCHs with multi-DCI scheduling, the terminal does not support changing the transmit power during a transmission, and the user can determine whether the transmit power of one panel determines that another panel is also transmitting PUSCHs. Let's assume that the minimum transmit power between the first transmit power of each panel and the first power limit corresponding to each panel is determined as the transmit power for uplink transmission of each panel.

[0154] For example, taking two panels as an example, multiple panels send PUSCHs with multi-DCI scheduling. The terminal does not support changing the transmit power at a transmission time. If Pcmax1 + Pcmax2 > Pcmax, then Ppanel1 = min{Pcmax1, P1} and Ppanel2 = min{Pcmax2, P2}.

[0155] Optionally, if the sum of the first power limits of each panel is greater than the total power limit, the sum of the first transmit power of each panel is not greater than the total power limit, and the multiple panels transmit PUSCHs with multi-DCI scheduling, the terminal does not support determining the first transmit power of each panel as the transmit power for uplink transmission of each panel when the transmit power is changed during a transmission.

[0156] For example, taking two panels as an example, multiple panels send PUSCHs with multi-DCI scheduling. The terminal does not support changing the transmit power during a single transmission, and Pcmax1 + Pcmax2 > Pcmax. If Ppanel1 + Ppanel2 <Pcmax,Ppanel1=P1,Ppanel2=P2。

[0157] Optionally, if the sum of the first power limits of each antenna panel is greater than the total power limit, the sum of the first transmit power of each panel is greater than the total power limit, the terminal does not support changing the transmit power at a transmission time, and the multiple panels transmit PUSCH with multiple DCI scheduling, the transmit power of each panel for uplink transmission is determined according to the ratio of the first transmit power of the multiple panels and the sum of the first transmit power of the multiple panels.

[0158] For example, taking two panels as an example, multiple panels send PUSCHs with multi-DCI scheduling. The terminal does not support changing the transmit power at a transmission time. If Pcmax1 + Pcmax2 > Pcmax, and Ppanel1 + Ppanel2 > Pcmax, then Ppanel1 = P1 * Pcmax / (P1 + P2) and Ppanel2 = P2 * Pcmax / (P1 + P2).

[0159] Optionally, if the sum of the first power limits of each panel is greater than the total power limit, and the sum of the first transmit powers of each panel is greater than the total power limit, the terminal does not support changing the transmit power at a transmission time, and the multiple panels send PUSCHs with multi-DCI scheduling, the transmit power for uplink transmission is determined for each panel in order of panel priority based on the first transmit power of the panel, until the sum of the determined transmit powers for uplink transmission of the panels reaches the power limit.

[0160] For example, let's illustrate this by having two panels send DG PUSCH and CG PUSCH respectively. See [link / reference] Figure 7 TRP 1 transmits CG PUSCH, TRP 2 transmits DG PUSCH, and multiple panels transmit PUSCHs with multiple DCI scheduling. The terminal does not support changing the transmit power at a transmission time. Pcmax1 + Pcmax2 > Pcmax. If Ppanel1 + Ppanel2 > Pcmax, then Ppanel2 = min{Pcmax2, P2}, and Ppanel1 = min{Pcmax - Ppanel2, P1}.

[0161] Below, we will explain the possible combination schemes mentioned above, where the sum of the first power limits of each panel is greater than the total power limit, the sum of the first transmit power of each panel is greater than the total power limit, and the terminal does not support changing the transmit power during a transmission.

[0162] Optionally, the transmit power of each panel needs to consider both the power limits of each individual panel and the total power limit. First, assume that the minimum value between the first transmit power of each panel and its corresponding first power limit is determined as the transmit power for uplink transmission of each panel, denoted as the second transmit power of each panel. Then, compare this second transmit power with the total power limit to determine the final transmit power. If the transmit power of each panel is less than or equal to the total transmit power limit, the transmit power of each panel is the assumed value; if the transmit power of each panel is greater than the transmit power limit, the transmit power for uplink transmission of each panel is determined according to the ratio of the first transmit powers of multiple panels and the sum of the first transmit powers of multiple panels. Alternatively, according to the priority of the panels, based on the first transmit power of each panel, the transmit power for uplink transmission of each panel is determined sequentially until the sum of the determined transmit powers for uplink transmission of all panels reaches the power limit.

[0163] Optionally, if the sum of the first power limits of each panel exceeds the total power limit, and multiple panels are transmitting PUSCHs with multi-DCI scheduling, the terminal does not support changing the transmit power during a transmission, and the user cannot determine whether the transmit power of one panel indicates that another panel is also transmitting PUSCHs. Priority processing can be used, for example, specifying that the first PUSCH transmitted has higher priority.

[0164] In the solution provided in this application embodiment, the transmission power of each panel is determined by different methods based on the different conditions met by the terminal panel, thereby ensuring the accuracy of the determined transmission power of each panel and thus ensuring the reliability of the terminal's communication based on the transmission power of the panel.

[0165] It should be noted that the above embodiments can be split into new embodiments, or combined with other embodiments to form new embodiments. This application does not limit the combination of embodiments.
