[0033] As shown in FIG2 , an embodiment of the present application provides a power control method 200 , which can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. The method includes the following steps.

[0034] S202: The terminal reports transmit power capability information, where the transmit power capability information is used to indicate a capability of the terminal related to transmit power in a physical uplink channel.

[0035] Optionally, the transmission power capability information may include first transmission power capability information and second transmission power capability information, the first transmission power capability information and the second transmission power capability information corresponding to a first service and a second service, respectively; wherein the first service may be a high-priority service, such as a voice service, an emergency service, etc.; the second service may be a low-priority service, an ordinary service, or a service other than the first service.

[0036] Optionally, the transmit power capability information includes: at least one of the following when the terminal supports transmission of target data (e.g., high-priority service data):

[0037] 1) Power level capability.

[0038] 2) Power adjustment capability.

[0039] 3) Maximum upstream duty cycle capability.

[0040] 4) Power level offset adjustment capability. For example, it indicates that the terminal supports the ability to adjust the power level offset when transmitting high-priority services. For another example, it indicates that the terminal supports the ability to adjust the power level offset to 0dB when transmitting high-priority services when the uplink duty cycle exceeds the limit.

[0041] 5) Uplink full power mode capability: For example, it indicates that the terminal supports the full power mode for uplink transmission of high-priority services when the uplink duty cycle exceeds the limit.

[0042] Optionally, the target data may be high-priority service data, such as voice service data, emergency service data, etc. This embodiment can determine the power level capability, power adjustment capability, maximum uplink duty cycle capability, power level offset adjustment capability, uplink full power mode capability, etc. when high-priority service data is transmitted, allowing the network to control and increase the uplink power of the terminal when performing high-priority service transmission when necessary, thereby improving transmission reliability.

[0043] The transmit power capability information is sent according to one of the following dimensions: per band, per band combination, per cell group, or per CC. The capability information is reported when the network requests the terminal to report capability information.

[0044] S204: The terminal obtains power configuration information.

[0045] The power configuration information may be used to indicate parameters related to transmit power.

[0046] In one embodiment, the network side device may send power configuration information in response to the transmit power capability information, so that the terminal can receive the power configuration information sent by the network side device.

[0047] In one embodiment, the terminal may obtain predefined or configured power configuration information.

[0048] Optionally, the power configuration information may include first power configuration information and second power configuration information, where the first power configuration information and the second power configuration information correspond to a first service and a second service, respectively. The first service may be a high-priority service, such as a voice service or an emergency service. The second service may be a low-priority service or a service other than the first service. This embodiment facilitates the terminal determining the transmit power for different services according to the power configuration information corresponding to each service, thereby improving the flexibility of power control.

[0049] S206: The terminal determines the transmit power of the physical uplink channel carrying target data based on the power configuration information.

[0050] Optionally, the target data may be high-priority service data, such as voice service data, emergency service data, etc. This embodiment helps the network control and increase the uplink transmission power of the terminal when necessary when transmitting high-priority services, thereby improving transmission reliability.

[0051] The above-mentioned physical uplink channels include but are not limited to physical random access channel (PRACH), physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), sounding reference signal (SRS), demodulation reference signal (DMRS), etc.

[0052] In the power control method provided in the embodiments of the present application, a terminal reports transmit power capability information, enabling network-side equipment to learn the terminal's transmit power-related capabilities on a physical uplink channel and subsequently transmit power configuration information. The terminal obtains the power configuration information and, based on the power configuration information, determines the transmit power of the physical uplink channel carrying target data. The embodiments of the present application facilitate network-side equipment to flexibly control the uplink power of the terminal when performing target data transmission based on the terminal's transmit power capability information, thereby improving transmission quality.

[0053] In the related art, the terminal will offset the power level according to the duty cycle state and trigger the reporting of the power level offset. At this time, the maximum transmit power that the terminal can support will change (for example, when the duty cycle is large, the transmit power will become smaller), and the full power capability may also change. However, in order to improve the reliability of specific high-priority service transmission, the terminal expects to keep the power level offset as small as possible even when the duty cycle is high, and the terminal expects the full power capability to remain unchanged as much as possible. The power control method provided in the embodiment of the present application can determine the transmit power capability information when there is high-priority service data transmission, such as power level capability, power adjustment capability, maximum uplink duty cycle capability, power level offset adjustment capability, uplink full power mode capability, etc., so that the network can control and increase the uplink power of the terminal when performing high-priority service transmission when necessary, thereby improving transmission reliability.

[0054] Optionally, the method further includes the following steps: the terminal sends power assistance information, and the power assistance information is used for at least one of the following: transmit power adjustment, scheduling strategy determination, and configuration or reconfiguration of transmit power-related parameters.

[0055] In this embodiment, the network-side device can adjust the transmit power of the terminal by sending power configuration information or dynamic signaling; the network-side device can also determine a scheduling policy and schedule the terminal; the network-side device can configure or reconfigure transmit power-related parameters of the terminal by sending power configuration information. The configuration or reconfiguration of the transmit power-related parameters may include configuration of a full power mode.

[0056] In this embodiment, the terminal may send power assistance information before obtaining the power configuration information, so that the network side device may determine the power configuration information based on the sending power capability information and the power assistance information; wherein, the power configuration information is determined based on the sending power capability information and the power assistance information.

[0057] In this embodiment, the terminal may send power assistance information after acquiring the power configuration information, so that the network side device may also adjust the terminal's transmit power related parameters through dynamic signaling, such as through downlink control information (DCI).

[0058] Optionally, in any one of the above implementations, the terminal sending the power assistance information includes: the terminal sending the power assistance information when a first condition is met; wherein the first condition includes at least one of the following:

[0059] 1) The network enables reporting of the power assistance information.

[0060] 2) The network enables a power control mechanism when sending the target data (such as high-priority service data).

[0061] 3) The terminal has uplink resources capable of accommodating the power assistance information.

[0062] 4) The uplink working cycle state exceeds the boundary.

[0063] 5) The terminal reports the power level offset. Optionally, the network also enables power control during transmission of target data (such as high-priority service data).

[0064] 6) The terminal triggers a Power Headroom Report (PHR).

[0065] 7) The terminal obtains user permission.

[0066] 8) The uplink duty cycle state returns to the target power level after exceeding the boundary.

[0067] For example, in this embodiment, when the network enables power control during high-priority service data transmission, and allows power assistance information reporting, and there are uplink resources that can accommodate the power assistance information, and the uplink working cycle state exceeds the boundary, and the reporting timer is not running, the terminal can send power assistance information.

[0068] Additionally, when the terminal sends power assistance information, the terminal may also trigger PHR. For example, when the uplink duty cycle state exceeds the boundary and the network enables power control when high-priority service transmission is enabled, the terminal triggers PHR.

[0069] Optionally, based on any one of the above embodiments, the method further includes: the terminal requests user permission, and the user permission is used to authorize power control permission when sending the target data.

[0070] In this embodiment, if the terminal has at least the transmit power capability corresponding to the transmit power capability information, a user permission request may be presented to the user, where the user permission is used to authorize power control permission for transmitting the target data. Additionally, only after receiving the user permission can the transmit power capability information be reported, and subsequent power control actions be performed.

[0071] Optionally, in any one of the above implementations, the power assistance information includes at least one of the following:

[0072] 1) The remaining effective time of the power level capability corresponding to the target data transmission. For example, the remaining effective time (such as 1s) of the power level capability corresponding to the high-priority service data transmission. During this remaining time, the terminal can perform high-priority service transmission according to the power level.

[0073] 2) The remaining effective time of the maximum uplink duty cycle capability corresponding to the target data transmission. For example, the remaining effective time of the maximum uplink duty cycle capability corresponding to the transmission of high-priority services. During this remaining time, the terminal can transmit high-priority services based on the maximum uplink duty cycle capability, thereby improving the transmission performance of high-priority services.

[0074] 3) The remaining effective time of the power level offset adjustment corresponding to the target data transmission, for example, the remaining effective time of the power level offset adjustment corresponding to the high-priority service transmission, during which the terminal can perform high-priority service transmission according to the adjusted power level offset.

[0075] 4) The remaining effective time of the uplink full power mode corresponding to the target data transmission, for example, the remaining effective time of the uplink full power mode capability corresponding to the high priority service transmission, during which the terminal can perform high priority service transmission according to the uplink full power mode.

[0076] 5) The maximum power corresponding to the target data transmission. For example, the maximum power corresponding to the high priority service transmission (P Cmax ), the maximum power value can be associated with the serving cell and the carrier frequency.

[0077] 6) The power level offset value corresponding to the target data transmission, for example, the power level offset value corresponding to the high priority service transmission.

[0078] 7) A first power headroom corresponding to transmitting the target data based on the first waveform, for example, a first power headroom (PH) corresponding to transmitting a high-priority service based on the first waveform.

[0079] 8) A second power headroom corresponding to transmitting the target data based on the second waveform, for example, a second power headroom (PH) corresponding to transmitting a high-priority service based on the second waveform.

[0080] For example, the first waveform may be a CP-OFDM waveform, and the second waveform may be a DFT-s-OFDM waveform. For another example, the first waveform may be a DFT-s-OFDM waveform, and the second waveform may be a waveform obtained by performing OCC (Orthogonal Cover Codes) on the data and then performing DFT-s-OFDM.

[0081] 9) The terminal radio frequency is restored to an initial power level, which may be determined according to power level capability.

[0082] Optionally, the above-mentioned power assistance information can be carried through a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), such as a media access control control element (MAC CE), or through a physical uplink control channel (PUCCH), such as a scheduling request (SR).

[0083] Furthermore, if dynamic waveform switching is enabled on the currently activated bandwidth part (Band Width Part, BWP), the terminal simultaneously reports a first power margin (PH) corresponding to high-priority service transmission based on the first waveform and a second power margin (PH) corresponding to high-priority service transmission based on the second waveform.

[0084] Optionally, in any of the above implementations, after the terminal determines the transmission power of the physical uplink channel carrying the target data based on the power configuration information, the method further includes: the terminal sending the target data through the physical uplink channel based on the transmission power.

[0085] In one embodiment, the target data includes an SR or non-contention random access (Contention Free Random Access, CFRA) preamble code, and the terminal sends the target data through the physical uplink channel based on the transmit power, including: when the uplink working cycle state exceeds the boundary and returns to the target power level, the terminal triggers an SR or non-contention random access process, and the non-contention random access process uses the CFRA preamble code; based on the transmit power, the SR or CFRA preamble code is sent through the physical uplink channel using dedicated resources.

[0086] In this embodiment, the network can configure an independent PUCCH-SR or CFRA resource to carry information that the terminal radio frequency has returned to the initial power level. When the terminal returns to the target power level after the uplink duty cycle state exceeds the boundary, an SR or non-contention random access process can be triggered, and the independent PUCCH-SR or CFRA preamble resource can be used to send an SR or a CFRA preamble. The SR is then canceled after the SR is sent, or the CFRA process is terminated when the physical downlink control channel (PDCCH) scheduling scrambled by the cell radio network temporary identity (Cell-Radio Network Temporary Identity, C-RNTI) is received.

[0087] The following will be divided into multiple embodiments to introduce the power control of messages during random access and the power control of PUSCH or PUCCH during high-priority service transmission.

[0088] When initiating a random access process (including 4-step CBRA and 2-step CBRA processes), the terminal can determine the transmit power of uplink messages (such as Msg1 / MsgA / Msg3, Msg4 HARQ-ACK, Msg5).

[0089] In one embodiment, the target data includes target data related to a random access process, and the terminal determines, based on the power configuration information, the transmit power of a physical uplink channel carrying the target data, including: when at least one of the following conditions is met, the terminal determines, based on the power configuration information, a maximum power, and determines, based on the maximum power, the transmit power of the physical uplink channel carrying the target data (for example, power control when a terminal upper layer indicates that a terminal lower layer allows transmission of high-priority services):

[0090] 1) The terminal has the power capability corresponding to the transmission power capability information.

[0091] 2) The cause value corresponding to the RRC connection establishment or recovery process that triggers the random access process is an agreed value (such as emergency service).

[0092] 3) The reason for triggering the random access process is that the target data arrives and the uplink is not synchronized, and the target data is high-priority service data. In this example, the network can be configured to indicate that the data carried by a logical channel (LCH), radio bearer (RB), quality of service flow (QoS flow), or protocol data unit session (PDU session) is high-priority service data, and the terminal confirms that the data is high-priority service data based on the indication.

[0093] 4) The reason for triggering the random access procedure is due to a lack of PUCCH resources for SR, and the triggered SR is due to the high priority service data to be sent triggering a buffer status report (BSR).

[0094] 5) The PDCCH signaling received by the terminal includes indication information, where the indication information is used to enable power control when the target data is allowed to be sent.

[0095] 6) The uplink working cycle state exceeds the boundary.

[0096] 7) The higher layer of the terminal indicates that power control is allowed when sending the target service.

[0097] In this embodiment, during the uplink message (e.g., Msg1 / MsgA) transmission process, if the uplink duty cycle state exceeds the boundary and the upper layer of the terminal indicates that power control is allowed when high-priority service transmission is allowed, the maximum power P is determined according to the power capability corresponding to the high-priority service. Cmax , thereby determining the sending power of the uplink message.

[0098] For example, the terminal supports the ability to adjust the power level offset to 0dB when transmitting high-priority services when the uplink duty cycle state exceeds the boundary. Then the terminal determines the maximum power P of the uplink message transmission power based on 0dB. Cmax In the process of sending Msg3, Msg4HARQ-ACK, and Msg5 messages, P Cmax The value is Msg1 or MsgA power control P Cmax .

[0099] In cases other than the above embodiment, the terminal may determine the maximum power of data related to the random access process according to protocol provisions.

[0100] The following describes the power control of PUSCH or PUCCH when transmitting high-priority services. When the network schedules high-priority service transmission, the terminal determines the transmit power of uplink messages PUSCH and PUCCH (such as HARQ feedback).

[0101] Optionally, the terminal determining, based on the power configuration information, the transmit power of the physical uplink channel carrying the target data includes: determining a maximum power based on the power configuration information, and determining the transmit power of the physical uplink channel carrying the target data based on the maximum power when at least one of the following conditions is met:

[0102] 1) The terminal has the power capability corresponding to the transmission power capability information.

[0103] 2) The uplink duty cycle state exceeds the boundary.

[0104] 3) The network enables power control when sending the target data.

[0105] In this example, the network can enable power control when sending the target data through indication information. For example, for downlink scheduling (DG) or downlink assignment (DL assignment), the network configures the DCI through PDCCH to carry power control indication information when enabling high-priority service transmission. For configured grant (Configured Grant, CG), the network configures the indication information through CG. For uplink-BWP configuration, the indication information is carried, and the BWP corresponding to the configuration is an activated BWP, and high-priority service data is assembled in the MAC PDU.

[0106] Furthermore, if the uplink scheduling (UL grant) DCI or the CG configuration carries this indication information, the terminal only assembles high-priority service data into the corresponding MAC PDU. For example, when the uplink data belongs to high-priority service data, the network can be configured to indicate that one or more LCHs are used to carry high-priority service data, and the MAC layer only multiplexes and assembles the data carried in these LCHs into the corresponding MAC PDU.

[0107] 4) At least one of the following corresponding to the target data transmission is a non-negative number: the remaining effective time of the power level capability; the remaining effective time of the power level offset adjustment. For example, when sending an uplink message, the remaining effective time of the power level capability corresponding to the high-priority service transmission is a non-negative number or the corresponding timer is running; or the remaining effective time of the power level offset adjustment corresponding to the high-priority service transmission is a non-negative number or the corresponding timer is running.

[0108] In cases other than the above embodiments, the terminal determines the maximum power of PUSCH and PUCCH according to protocol regulations.

[0109] The power control method according to an embodiment of the present application is described in detail above in conjunction with FIG2 . The power control method according to another embodiment of the present application will be described in detail below in conjunction with FIG3 . It will be understood that the interaction between the network-side device and the terminal described from the perspective of the network-side device is the same as or corresponds to the description of the terminal side in the method shown in FIG2 .
