In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following contents.

In order to facilitate a better understanding of the embodiments of the present application, the antenna panel (panel) related to the present application will be described.

With the continuous evolution of antenna packaging technology, multiple antenna elements (antenna elements) can be nested and combined with chips to form an antenna panel (panel) or antenna array block, which makes it possible to configure multiple low-correlation panels in the transmitter. possible. Through multi-antenna beam shaping technology, the transmission signal energy is concentrated in a certain direction for transmission, which can effectively improve coverage and thereby improve communication performance. Multiple panels can independently form transmission beams, so that a terminal transmitter can simultaneously send data streams on multiple panels through different beams to improve transmission capacity or reliability.

The terminal needs to notify the network side of the number of configured antenna panels in the capability report. At the same time, the terminal may also need to notify the network side whether it has the ability to transmit signals on multiple antenna panels simultaneously. Since the channel conditions corresponding to different panels are different, different panels need to adopt different transmission parameters according to their respective channel information. In order to obtain these transmission parameters, different Sounding Reference Signal (SRS) resources need to be configured for different panels to obtain uplink channel information. For example, in order to perform uplink beam management, an SRS resource set can be configured for each panel, so that each panel performs beam management separately and determines independent analog beams. In order to obtain the precoding information used for Physical Uplink Shared Channel (PUSCH) transmission, you can also configure an SRS resource set for each panel to obtain the beams, precoding vectors, and Transmission parameters such as the number of transmission layers. At the same time, multi-panel transmission can also be applied to the Physical Uplink Control Channel (PUCCH), that is, the information carried by the same PUCCH resource or the PUCCH resource on the same time domain resource can be sent to the network side through different panels at the same time.

In order to determine the panel used to transmit signals, the terminal can receive multiple reference signal resource sets configured by the network device. Different reference signal resource sets use different panels to send or receive reference signals. For example, the network device can configure multiple channel state information reference signal (CSI-RS) resource sets, and different sets are received on different panels; or the network device can configure multiple reference signal sets, and different sets Sent on different panels; alternatively, the network device can indicate multiple physical cell identifiers (Physical Cell Identifier, PCI), and the synchronization signal block (Synchronization Signal Block, SSB) associated with each PCI as a set, so that different sets Received on different panels. At this time, each uplink signal can be associated with a reference signal set, or be configured with a reference signal indication information (such as Transmission Configuration Indicator (TCI) status or SRS resource indicator (SRS resource indicator, SRI) information) to indicate a The signal in the reference signal set is used as the sending or receiving panel of the associated reference signal set as the sending panel of the uplink signal. Alternatively, the network device can configure a panel identification (ID) for each uplink signal, and determine the sending panel of the uplink signal based on the panel ID. Therefore, uplink signals transmitted on different panels can be called uplink signals associated with different reference signal resource sets, or uplink signals associated with different panel IDs. At this time, uplink signals associated with the same reference signal resource set, or uplink signals associated with the same panel ID, are transmitted using the same panel.

It should be noted that SSB can also be called synchronization signal/physical broadcast channel block (SS/PBCH block).

In order to facilitate a better understanding of the embodiments of the present application, the uplink non-coherent transmission related to the present application will be described.

Uplink non-coherent transmission based on multiple Transmission Reception Points (TRPs) is introduced in the NR system. Among them, the backhaul connection between TRPs can be ideal or non-ideal. Under ideal backhaul, TRPs can quickly and dynamically exchange information. Under non-ideal backhaul, due to the large delay, only TRPs can interact with each other. Ability to interact with information quasi-statically. Different TRPs can also independently schedule PUSCH transmission of the same terminal. Different PUSCH transmissions can be configured with independent transmission parameters, such as beams, precoding matrices, number of layers, etc. Scheduled PUSCH transmissions can be transmitted in the same time slot or in different time slots. If the terminal is simultaneously scheduled for multiple PUSCH transmissions in the same time slot, it needs to determine how to perform the transmission based on its own capabilities. If the terminal is configured with multiple panels and supports simultaneous transmission of PUSCH on multiple panels, the multiple PUSCHs can be transmitted simultaneously, and the PUSCHs transmitted on different panels are aligned with the corresponding TRP for simulation shaping, thereby distinguishing through the spatial domain. Different PUSCHs provide uplink spectrum efficiency (a in Figure 2). If the terminal has only a single panel, or does not support simultaneous transmission of multiple panels, PUSCH can only be transmitted on one panel.

PUSCH transmitted by different TRPs can be scheduled based on multiple downlink control information (Downlink Control Information, DCI), and these DCI can be carried by different control resource sets (Control Resource Set, CORESET). Specifically, multiple CORESET groups are configured on the network side, and each TRP is scheduled using the CORESET in its own CORESET group. That is, different TRPs can be distinguished by the CORESET group. For example, the network device can configure a CORESET group index for each CORESET, and different indexes correspond to different TRPs. PUSCH transmitted to different TRPs can also be scheduled based on a single DCI. In this case, the DCI needs to indicate parameters such as beams and Demodulation Reference Signal (DMRS) ports used by PUSCH transmitted to different TRPs (as shown in the figure) b) in 2. In this way, different transmission layers of PUSCH are transmitted on different panels using independent transmission parameters (such as beams, precoding matrices, power control parameters, etc.), but the modulation and coding scheme (Modulation and Coding Scheme, MCS) and The physical resources are the same.

It should be noted that Figure 2 shows PUSCH transmission based on multiple panels. Specifically, a in Figure 2 is based on multiple DCIs, and b in Figure 2 is based on a single DCI.

In order to facilitate a better understanding of the embodiments of the present application, the uplink PUSCH power control related to the present application will be described.

The transmit power of PUSCH can be calculated by the following formula 1:

Among them, in Formula 1, P _CMAX,f,c (i) is the maximum transmit power supported by the terminal on carrier f of serving cell c, i is the index of a PUSCH transmission, and j is the open-loop power control parameter index (including target Power P _{O_PUSCH,b,f,c} (j) and path loss factor α _b,f,c (j)); q _d is the index of the reference signal used for path loss measurement, which is used to obtain the path loss value PL _{b , f,c} (q _d ), is also an open-loop power control parameter; f _b,f,c (i,l) is the closed-loop power control adjustment factor, where l is the closed-loop power control process. Wherein, the terminal device determines the closed-loop power adjustment factor according to a Transmission Power Control (TPC) command sent by the network side. The TPC command can be carried through the DCI used to schedule the PUSCH in the terminal search space, or it can Carried via DCI format 2_2 used to carry group TPC commands in the common search space.

In the NR system, the terminal equipment determines the scheduled transmission beam of the PUSCH based on the SRI in the DCI, and also determines the power control parameters used by the PUSCH based on the SRI. Specifically, the network side configures multiple SRI-PUSCH-PowerControl parameter fields in advance through Radio Resource Control (RRC) signaling. Each parameter field corresponds to an SRI value, and the parameter field contains the corresponding SRI value. A set of PUSCH power control parameter configurations (such as j, q _d , l). When the values indicated by SRI are different, the power control parameter configuration in the corresponding parameter field (SRI-PUSCH-PowerControl) is used to determine the transmit power of the currently scheduled PUSCH.

In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application will be described.

If the PUSCHs sent by different panels are independently scheduled through the DCI of their respective TRPs, the time-frequency resources of the PUSCHs sent by different panels may partially overlap (that is, the allocated RE parts are the same), or the uplink timing of the PUSCHs sent on different panels may be are different, resulting in possible overlap of OFDM symbols transmitting different PUSCHs. At this time, how to perform power control on overlapping OFDM symbols and non-overlapping OFDM symbols, so as to ensure the performance of uplink transmission as much as possible within the allowed transmission power and terminal complexity, is a problem that needs to be solved.

Based on the above problems, this application proposes an uplink power control scheme. When the OFDM symbols transmitting different uplink signals partially overlap, the transmit power on the overlapping OFDM symbols and the non-overlapping OFDM symbols can be determined to ensure that each The sum of transmit power on OFDM symbols does not exceed the total power limit, thereby optimizing the power control of uplink transmission.

The technical solutions of the present application are described in detail below through specific examples.

Figure 3 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in Figure 3, the wireless communication method 200 may include at least part of the following content:

S210: The terminal equipment determines the transmit power of the first uplink signal on M OFDM symbols and N OFDM symbols; wherein, the M OFDM symbols and the N OFDM symbols are used to transmit the first uplink signal, and the M OFDM symbols are used to transmit the first uplink signal. OFDM symbols are also used to transmit the second uplink signal, and M and N are both positive integers.

In this embodiment of the present application, the first uplink signal is transmitted using M+N OFDM symbols, of which the M OFDM symbols are also used to transmit the second uplink signal, that is, the first uplink signal and the second uplink signal are transmitted. OFDM symbols partially overlap. At this time, for the first uplink signal, the M OFDM symbols are called overlapping OFDM symbols, and the N OFDM symbols are called non-overlapping OFDM symbols. When OFDM symbols transmitting different uplink signals partially overlap, ensure that the sum of the transmit power on each OFDM symbol does not exceed the total power limit by reasonably determining the transmit power on the overlapping OFDM symbols and the non-overlapping OFDM symbols. , thereby optimizing the power control of uplink transmission.

In some embodiments, the first uplink signal and the second uplink signal are PUSCH, or the first uplink signal and the second uplink signal are PUCCH or SRS. Of course, the first uplink signal and the second uplink signal may also be other uplink signals, and the embodiments of the present application are not limited thereto.

In some embodiments, the time domain resources allocated by the network device for the first uplink signal partially overlap with the time domain resources allocated for the second uplink signal, resulting in partial occurrence of OFDM symbols transmitting the first uplink signal and the second uplink signal. overlapping. Optionally, the first uplink signal and the second uplink signal adopt the same uplink timing, that is, the OFDM symbol boundaries of the two are aligned; alternatively, the first uplink signal and the second uplink signal can also adopt different uplink timing, that is, The OFDM symbol boundaries of the two are not aligned.

For example, as shown in Figure 4, one time slot of a carrier contains 14 OFDM symbols, of which OFDM symbols 0-10 are used to send the first uplink signal, and OFDM symbols 6-12 are used to send the second uplink signal. . Among them, the non-overlapping OFDM symbols are OFDM symbols 0-5 (that is, N OFDM symbols are OFDM symbols 0-5), which are only used to transmit the first uplink signal; the overlapping OFDM symbols are OFDM symbols 6-10 (that is, M OFDM symbols are OFDM symbols 6-10), which are used to transmit both the first uplink signal and the second uplink signal.

In some embodiments, the first uplink signal is scheduled by the first downlink signaling, the second uplink signal is scheduled by the second downlink signaling, and the time domain resource portion indicated by the first downlink signaling and the second downlink signaling Overlap, resulting in partial overlap of OFDM symbols transmitting the first uplink signal and the second uplink signal. Optionally, the first downlink signaling is DCI, and the second downlink signaling is DCI; or, the first downlink signaling is RRC signaling, and the second downlink signaling is RRC signaling.

Specifically, the time domain resources of the first uplink signal partially overlap with the time domain resources of the second uplink signal, which refers to the first time domain resource (OFDM symbol) indicated by the first downlink signaling for transmitting the first uplink signal. , which is different from the second time domain resource used to transmit the second uplink signal indicated by the second downlink signaling, but there is partial overlap of OFDM symbols. In addition, the first downlink signaling schedules the transmission of the first uplink signal on the first panel, and the second downlink signaling schedules the transmission of the second uplink signal on the second panel. The first panel and the second panel are different. Therefore, the first The uplink signal and the second uplink signal can also be transmitted simultaneously on overlapping time domain resources. Here, the first downlink signaling and the second downlink signaling may also be other downlink signaling, such as the first high-layer signaling and the second high-layer signaling.

In some embodiments, the uplink timing of the first uplink signal and the second uplink signal are different, resulting in partial overlap of OFDM symbols transmitting the first uplink signal and the second uplink signal. That is, the OFDM symbol boundaries transmitted by the first uplink signal and the second uplink signal are not aligned. For example, as shown in Figure 5, one time slot of a carrier contains 14 OFDM symbols, of which symbols 0-10 are used to send the first uplink signal, and OFDM symbols 6-12 are used to send the second uplink signal. Since the uplink timing of the first uplink signal and the second uplink signal are different, the uplink timing of the second uplink signal is delayed for a period of time, and the time slot boundaries of the first uplink signal and the second uplink signal are not aligned, causing the first uplink signal to Say, the starting position of the second uplink signal is in the middle of OFDM symbol 6, and the end position of the second uplink signal is in the middle of OFDM symbol 13. Among them, the non-overlapping OFDM symbols are OFDM symbols 0-5 (that is, N OFDM symbols are OFDM symbols 0-5), which are only used to transmit the first uplink signal; the overlapping OFDM symbols are OFDM symbols 6-10 (that is, M OFDM symbols are OFDM symbols 6-10), which are used to transmit both the first uplink signal and the second uplink signal.

In some embodiments, the first uplink signal is scheduled by the first downlink signaling, the second uplink signal is scheduled by the second downlink signaling, and the time domain resources indicated by the first downlink signaling and the second downlink signaling are completely The same or no overlap at all, but the uplink timing adopted by the first uplink signal and the second uplink signal is different, resulting in partial overlap of OFDM symbols for transmitting the first uplink signal and the second uplink signal.

For another specific example, the time domain resources indicated by the first downlink signaling and the second downlink signaling are exactly the same, but the uplink timing adopted by the first uplink signal and the second uplink signal is different, resulting in that the first uplink signal and the second uplink signal are The time windows for signal transmission are not exactly the same, as shown in Figure 6 (the first uplink signal and the second uplink signal both occupy OFDM 0-10, but the uplink timing difference between the first uplink signal and the second uplink signal is more than one symbol).

For another specific example, the time domain resources indicated by the first downlink signaling and the second downlink signaling do not overlap at all, but because the first uplink signal and the second uplink signal adopt different uplink timings, the first uplink signal and the second uplink signal do not overlap. There is overlap in the sending time of the two uplink signals, as shown in Figure 7 (the first uplink signal uses OFDM symbols 0-5, and the second uplink signal uses OFDM symbols 6-10).

In one implementation, the first downlink signaling indicates that the first uplink signal is associated with a first SRS resource set, the second downlink signaling indicates that the second uplink signal is associated with a second SRS resource set, and the first SRS resource set and the The second SRS resource set is different.

In one implementation, the M OFDM symbols include one or two first OFDM symbols, wherein a part of each first OFDM symbol is used to simultaneously transmit the first uplink signal and the second uplink signal, The remaining part is only used to transmit the first uplink signal, and the transmission power of the first uplink signal on the first OFDM symbol is determined based on the assumption that the first uplink signal and the second uplink signal are transmitted simultaneously. That is, the first OFDM symbol is a partially overlapping OFDM symbol. For the partially overlapping OFDM symbol, the terminal device calculates the transmit power on the partially overlapping OFDM symbol based on the assumption of complete overlap.

For example, as shown in Figure 5, for the first uplink signal, OFDM symbol 6 is a partially overlapping OFDM symbol (ie, the first OFDM symbol), and OFDM symbols 7-10 are completely overlapping OFDM symbols, that is, M OFDM symbols. The symbols include OFDM symbols 6-10, where OFDM symbol 6 is the first OFDM symbol.

For another specific example, as shown in Figure 6, for the first uplink signal, OFDM symbol 1 is a partially overlapping OFDM symbol (ie, the first OFDM symbol), and OFDM symbols 2-10 are completely overlapping OFDM symbols, that is, M OFDM symbols. The symbols include OFDM symbols 1-10, where OFDM symbol 1 is the first OFDM symbol.

For another specific example, as shown in Figure 7, for the first uplink signal, OFDM symbol 5 is a partially overlapping OFDM symbol (ie, the first OFDM symbol), that is, the M OFDM symbols only include OFDM symbol 5.

For another specific example, as shown in Figure 8 below, for the first uplink signal, there are two partially overlapping OFDM symbols, namely OFDM symbol 6 and OFDM symbol 10 (ie, the first OFDM symbol).

Specifically, the terminal device may determine the transmit power on the fully overlapping OFDM symbols as the transmit power on the partially overlapping OFDM symbols. That is, the terminal device calculates the transmit power on the partially overlapping OFDM symbols based on the assumption of complete overlap. For example, in Figure 8, the terminal device can use the calculated transmit power on OFDM symbols 7-9 as the transmit power on OFDM symbol 6 and OFDM symbol 10.

Therefore, in the embodiment of the present application, the terminal equipment only needs to perform power control in units of OFDM symbols, and does not need to determine the transmit power separately for the overlapping portion and the non-overlapping portion within the OFDM symbol, thereby reducing the complexity of implementation and also reducing the complexity of the implementation. It can be guaranteed that the transmit power of the terminal will not exceed the limit.

In this embodiment of the present application, when the time domain resources used by the two PUSCHs sent by the terminal equipment on different antenna panels (panels) partially overlap, the terminal equipment needs to reduce the transmission power on the overlapping resources, or the terminal equipment The device needs to reduce the transmit power of the entire PUSCH at the same time to ensure that the sum of the transmit power on each OFDM symbol does not exceed the total power limit. At the same time, considering that the uplink timing used by the two PUSCHs may be different, OFDM symbols may partially overlap. In this case, the partially overlapping OFDM symbols need to be treated as overlapping OFDM symbols to ensure that the transmit power is within one OFDM symbol. stable.

Embodiment 1, the above S210 may specifically include:

The terminal equipment calculates the transmission power of the first uplink signal on the M OFDM symbols, and the terminal equipment determines the transmission power of the first uplink signal on the M OFDM symbols as the first uplink signal on the N OFDM symbols. transmit power on.

That is to say, the terminal device does not need to calculate the transmit power on the non-overlapping OFDM symbols, and directly uses the calculated transmit power on the overlapping OFDM symbols as the transmit power on the non-overlapping OFDM symbols. At this time, the first uplink signal uses the same transmission power on all OFDM symbols, that is, the transmission power on overlapping OFDM symbols.

In some implementations, taking PUSCH as an example, the terminal equipment can calculate the expected transmission of the first uplink signal and the second uplink signal according to the above formula 1 and the respective power control parameters of the first uplink signal and the second uplink signal. power.

In some implementations of Embodiment 1, if the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal does not exceed the maximum transmit power supported by the terminal device, the terminal device may use the The expected transmission power of an uplink signal is used as the actual transmission power of the first uplink signal. That is, the transmission power of the first uplink signal on the M OFDM symbols is the expected transmission power of the first uplink signal.

In some implementations of Embodiment 1, when the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, the first uplink The transmission power of the signal on the M OFDM symbols is the reduced expected transmission power of the first uplink signal. In other words, if the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, the terminal device reduces the expected transmit power of the first uplink signal as the third The transmit power of an uplink signal on overlapping OFDM symbols so that the sum of the expected transmit powers of the first uplink signal and the second uplink signal does not exceed the maximum transmit power supported by the terminal device. For example, the terminal device can reduce the expected transmission power of the first uplink signal and the expected transmission power of the second uplink signal in equal proportions to obtain the actual transmission power of the first uplink signal on M OFDM symbols.

In some implementations of Embodiment 1, the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, and the first uplink signal If the priority is lower than the priority of the second uplink signal, the transmission power of the first uplink signal on the M OFDM symbols is the reduced expected transmission power of the first uplink signal.

In other words, if the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, and the priority of the first uplink signal is lower than the priority of the second uplink signal level, the terminal equipment reduces the expected transmission power of the first uplink signal as the transmission power of the first uplink signal on the overlapping OFDM symbols. If the priority of the first uplink signal is higher than the priority of the second uplink signal, there is no need to reduce the expected transmit power. The terminal device can use the expected transmit power of the first uplink signal as the first uplink signal on the overlapping OFDM symbols. Actual transmit power.

In some embodiments, the priority of the first uplink signal and the priority of the second uplink signal may be determined based on one of the following:

The types of the first uplink signal and the second uplink signal, the information carried by the first uplink signal and the second uplink signal, and the order in which the first uplink signal and the second uplink signal are sent.

Therefore, in Embodiment 1, if the transmission power difference between overlapping OFDM symbols and non-overlapping OFDM symbols is large, the phase discontinuity between OFDM symbols will be caused by the terminal radio frequency device, thus affecting the demodulation of the first uplink signal. performance. This embodiment can ensure that the power of the first uplink signal on different OFDM symbols is the same, thereby avoiding phase discontinuity, and also has relatively low requirements on the radio frequency devices of the terminal.

Embodiment 2, the above S210 may specifically include:

The terminal equipment determines the transmit power of the first uplink signal on the M OFDM symbols and the N OFDM symbols respectively.

In some embodiments, taking PUSCH as an example, the terminal device can calculate the expected transmission of the first uplink signal and the second uplink signal according to the above formula 1 and the respective power control parameters of the first uplink signal and the second uplink signal. power.

In Embodiment 2, the terminal device can calculate the transmission power on the non-overlapping OFDM symbols and the overlapping OFDM symbols respectively according to the above formula 1 or the solution in Embodiment 1, and then transmit based on both the non-overlapping OFDM symbols and the overlapping OFDM symbols. The value of the power is used to obtain the transmit power of the first uplink signal. That is to say, the main difference between Embodiment 2 and Embodiment 1 is that the terminal device needs to independently calculate the transmit power on non-overlapping OFDM symbols.

In some implementations of Embodiment 2, when the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, the first uplink The transmission power of the signal on the M OFDM symbols is the reduced expected transmission power of the first uplink signal. For example, the terminal device can reduce the expected transmission power of the first uplink signal in an equal proportion to obtain the actual transmission power of the first uplink signal on M OFDM symbols.

In some implementations of Embodiment 2, the sum of the expected transmit power of the first uplink signal and the expected transmit power of the second uplink signal exceeds the maximum transmit power supported by the terminal device, and the first uplink signal If the priority is lower than the priority of the second uplink signal, the transmission power of the first uplink signal on the M OFDM symbols is the reduced expected transmission power of the first uplink signal. For example, the terminal device can reduce the expected transmission power of the first uplink signal in an equal proportion to obtain the actual transmission power of the first uplink signal on M OFDM symbols.

In some implementations of Embodiment 2, the terminal device first calculates the transmit power of the first uplink signal on the M OFDM symbols and the N OFDM symbols according to the above method;

When the difference in transmit power of the first uplink signal on the M OFDM symbols and the N OFDM symbols exceeds the first threshold value, the terminal equipment transmits the first uplink signal on the M OFDM symbols. The transmit power is set to zero, or the terminal device determines the transmit power of the first uplink signal on the M OFDM symbols as the transmit power of the first uplink signal on the N OFDM symbols. In other words, if the difference between the transmission power of the first uplink signal on the non-overlapping OFDM symbol and the overlapping OFDM symbol exceeds the first threshold value, then the transmission power on the overlapping OFDM symbol is determined as the transmission power on the non-overlapping OFDM symbol. , at this time, the transmit power of different OFDM symbols of the first uplink signal is the same. Alternatively, the terminal equipment may also set the transmission power on the overlapping OFDM symbols to zero, that is, it does not send the first uplink signal on the overlapping OFDM symbols, but only sends the first uplink signal on the non-overlapping OFDM symbols.

In some embodiments, the first threshold value is determined by the terminal device and reported to the network device, or the first threshold value is configured by the network device, or the first threshold value is agreed upon by a protocol.

Therefore, when the difference between the transmission power of the first uplink signal on M OFDM symbols and N OFDM symbols is large, the transmission power of the first uplink signal on M OFDM symbols and N OFDM symbols can be processed. Effectively avoid phase discontinuity between OFDM symbols and avoid power waste. At the same time, when the difference in transmit power of the first uplink signal between M OFDM symbols and N OFDM symbols is small and does not cause phase discontinuity, no adjustment is performed, so as to ensure the transmission performance of the first uplink signal as much as possible.

In some implementations of Embodiment 2, the terminal device first calculates the transmit power of the first uplink signal on the M OFDM symbols and the N OFDM symbols according to the above method; then, the terminal device calculates the first uplink signal on the M OFDM symbols and the N OFDM symbols. The average or smaller value of the transmission power of the uplink signal on the M OFDM symbols and the N OFDM symbols is determined as the transmission power of the first uplink signal on the M OFDM symbols and the N OFDM symbols.

In other words, the terminal device averages the transmission power of the first uplink signal on the non-overlapping OFDM symbols and the overlapping OFDM symbols, and determines the actual transmission power of the first uplink signal on the non-overlapping OFDM symbols and the overlapping OFDM symbols. Specifically, the terminal equipment can average the linear values of the transmission power of the first uplink signal on non-overlapping OFDM symbols and overlapping OFDM symbols to obtain the actual transmission of the first uplink signal on M OFDM symbols and N OFDM symbols. power.

In other words, the terminal equipment determines the smaller value of the transmission power of the first uplink signal on the non-overlapping OFDM symbols and the overlapping OFDM symbols as the actual transmission power of the first uplink signal on the M OFDM symbols and N OFDM symbols. Transmit power.

In the second manner, the terminal device determines the transmit power of the first uplink signal on the M OFDM symbols and the N OFDM symbols respectively.

Optionally, in the first manner, the terminal device may determine the transmit power of the first uplink signal on M OFDM symbols and N OFDM symbols based on the above-mentioned Embodiment 1.

Optionally, in the second manner, the terminal device may determine the transmit power of the first uplink signal on M OFDM symbols and N OFDM symbols based on the above-mentioned Embodiment 2.

In some embodiments, when the transmission power of the first uplink signal on the M OFDM symbols is less than or equal to the second threshold value, the terminal device only sends the first uplink signal on the N OFDM symbols. signal, or the terminal device does not send the first uplink signal.

In some embodiments, the second threshold value is determined by the terminal device and reported to the network device, or the second threshold value is configured by the network device, or the second threshold value is agreed upon by the protocol. Optionally, the second threshold value is 0dBm.

In other words, if the transmission power of the first uplink signal on the overlapping OFDM symbols is less than the second threshold or equal to the second threshold, the terminal device does not send the first uplink signal on the overlapping OFDM symbols, but only on the non-overlapping OFDM symbols. The first uplink signal is sent on the symbol. Alternatively, if the transmission power of the first uplink signal on the overlapping OFDM symbol is less than the second threshold or equal to the second threshold, the terminal device does not send the first uplink signal.

In some embodiments, the first uplink signal and the second uplink signal are scheduled to be transmitted on different antenna panels, or the first uplink signal and the second uplink signal are associated with different SRS resource sets.

In some embodiments, the terminal device sends the first uplink signal on the M OFDM symbols according to the determined transmit power of the first uplink signal on the M OFDM symbols; and/or, the terminal device sends the first uplink signal on the M OFDM symbols according to The transmission power of the first uplink signal on the N OFDM symbols is determined, and the first uplink signal is sent on the N OFDM symbols.

Therefore, in this embodiment of the present application, the terminal equipment determines the transmit power of the first uplink signal on M OFDM symbols and N OFDM symbols; wherein, the M OFDM symbols and the N OFDM symbols are used to transmit the first An uplink signal, the M OFDM symbols are also used to transmit a second uplink signal. Specifically, M OFDM symbols and N OFDM symbols are used to transmit the first uplink signal, and M OFDM symbols are also used to transmit the second uplink signal, that is, OFDM transmits the first uplink signal and the second uplink signal. Symbols overlap. In the case where the OFDM symbols transmitting the first uplink signal and the second uplink signal overlap, the terminal device can determine the transmit power of the first uplink signal on M OFDM symbols and N OFDM symbols to ensure that the The sum of transmit power does not exceed the total power limit, thereby optimizing the power control of uplink transmission.
