3. Power control of uplink signals/uplink channels

The transmit power calculation formula for each uplink signal/uplink channel is defined in the 3gpp 38.213 communication protocol. The following is a schematic explanation of the power control of SRS, PUSCH, and PUCCH.

(1) About PUSCH power control

The power allocation of PUSCH is determined through high-level signaling, or high-level signaling and physical layer signaling, or in a predefined manner by the protocol. High-layer signaling refers to radio resource control (RRC) signaling, and/ Or Media Access Control (MAC) signaling. Physical layer signaling refers to DCI. The RRC signaling configuration may be open-loop power control parameters, and the DCI indication may be closed-loop power control parameters. However, in a certain scenario, the user equipment uses the same power control parameters to determine the transmit power of different PUSCHs.

Based on the power control parameters contained in the physical uplink data channel configuration (also known as PUSCH-config), the PUSCH transmission power is specified in the communication protocol 3gpp 38.213, as follows:

If the terminal equipment uses the set configuration with the index value j and the PUSCH power control adjustment state value with the index value l in the partial bandwidth (Bandwidth Part, BWP) b of the carrier f in the serving cell c, then the terminal equipment determines that the PUSCH is at the transmission opportunity i The transmission power is P _PUSCH,b,f,c (i,j,q _d ,l), as shown in formula (1).

Among them, i is defined by the slot index, the first symbol S in the slot and multiple consecutive symbols L. j is the index of the open-loop parameter. l is the index of the closed-loop power control state. q _d is the reference signal (RS) resource index used for path loss measurement. The value of μ is determined based on the subcarrier spacing.

P _CMAX,f,c (i) is the maximum transmission power of the terminal equipment configured on carrier f of serving cell c at PUSCH transmission opportunity i.

P _{O_PUSCH,b,f,c} (j) is a parameter composed of the sum of members P _{O_NOMINAL_PUSCH,f,c} (j) and members P _{O_UE_PUSCH,b,f,c} (j), where j∈{0,1 ,...,j-1}. P _{O_PUSCH, b, f, c} (j) is the target power, and the target power includes a cell specific component (cell specific component) and a terminal equipment specific component (specific component). It can be understood that the aforementioned P _{O_NOMINAL_PUSCH,f,c} (j) can be regarded as a cell-specific component, and P _{O_UE_PUSCH,b,f,c} (j) can be regarded as a terminal equipment specific component.

Indicates the number of physical resource blocks (PRBs) occupied by the terminal device when sending PUSCH at the i-th PUSCH transmission opportunity.

PL _b,f,c (q _d ) is the path loss calculated by the terminal equipment through the reference signal corresponding to the reference signal index q _d on the downlink BWP.

f _{b, f, c} (i, l) are used for power control adjustment of closed-loop power control (Transmission Power Control, TPC).

(2) About PUCCH power control

The method of determining PUCCH transmit power based on PUCCH power control parameters is similar to the PUSCH power control mechanism. For details, please refer to 3gpp 38.331 and 3gpp 38.213. The PUCCH transmission power is specified in the communication protocol 3gpp 38.213, as follows:

If the terminal equipment uses the PUCCH power control adjustment status value with index value l in BWP b of carrier f in primary cell c, then the terminal equipment determines that the transmission power of PUCCH at transmission opportunity i is P _PUCCH,b,f,c (i, q _u ,q _d ,l), please refer to formula (2).

Among them, i is defined by the slot index, the first symbol S in the slot and multiple consecutive symbols L. q _u is the index of the open-loop parameters lead. l is the index of the closed-loop power control state. q _d is the RS resource index used for path loss measurement. The value of μ is determined based on the subcarrier spacing.

P _CMAX,f,c (i) is the maximum transmit power of the terminal equipment configured on carrier f of serving cell c at PUCCH transmission opportunity i.

P _{O_PUCCH,b,f,c} (q _u ) is a parameter composed of the sum of member P _{O_NOMINAL_PUCCH} and member P _{O_UE_PUCCH} (q _u ). P _{O_PUCCH,b,f,c} (q _u ) is the target power, which includes a cell specific component and a terminal equipment specific component. It can be understood that in this case, P _{O_NOMINAL_PUCCH} can be regarded as a cell-specific component, and P _{O_UE_PUCCH} (q _u ) can be regarded as a terminal equipment-specific component.

Indicates the number of PRBs occupied by the terminal device when sending PUCCH at the i-th PUCCH transmission opportunity.

g _{b, f, c} (i, l) are used for power control adjustment of TPC.

Δ _{F_PUCCH} (F) is related to the PUCCH format, and RRC has only one value for each PUCCH format.

(3) About SRS power control

Based on the power control parameters defined in the SRS-Resource Set domain, the SRS transmission power is specified in the communication protocol 3gpp38.213, as follows:

If the terminal equipment uses the SRS power control adjustment state value with an index value l in the partial bandwidth b of the carrier f in the serving cell c, the SRS transmission power sent by the terminal equipment at the SRS transmission opportunity i is P _SRS,b,f,c (i ,q _s ,l), please refer to formula (3).

Among them, i is defined by the slot index, the first symbol S in the slot and multiple consecutive symbols L. l is the index of the closed-loop power control state. q _d is the RS resource index used for path loss measurement. q _s is the SRS resource set identity document (ID). The value of μ is determined based on the subcarrier spacing.

P _CMAX,f,c (i) is the maximum transmit power of the terminal equipment configured on carrier f of serving cell c at SRS transmission opportunity i.

P _{O_SRS,b,f,c} (q _s ) is configured for the uplink BWP b of carrier f of serving cell c through the high-layer parameter p0. The SRS resource set q _s is configured through the high-level parameters SRS-Resource Set and SRS-Resource Set Id. P _{O_SRS,b,f,c} (q _s ) is used to characterize the target received power.

M _SRS,b,f,c (i) represents the number of PRBs occupied by the terminal device when sending SRS at the i-th SRS transmission opportunity.

α _SRS,b,f,c (q _s ) is configured through the high-level parameter alpha for the SRS resource set q _s of the uplink BWPb of carrier f of serving cell c, and is the path loss compensation factor. α _SRS,b,f,c (q _s ) is the scaling factor for the path loss.

PL _{b, f, c} (q _d ) is the path loss calculated by the terminal equipment through the reference signal corresponding to the reference signal index q _d on the downlink BWP, which is paired with the uplink BWP b of the carrier f of the serving cell c.

h _{b, f, c} (i, l) is the path loss calculated by the terminal equipment through the reference signal index q _d on the downlink BWP. The reference The signal is paired with the SRS resource set q _s of the uplink BWPb of carrier f of serving cell c. Among them, the reference signal index q _d associated with the SRS resource set q _s is determined by the ssb-Index (used to indicate the resource index of SS/PBCH) in the high-level parameter path loss Reference RS or the csi-RS-Index in the high-level parameter path lossReferenceRS. (Resource index used to indicate CSI-RS). It is the path loss measurement value of the terminal device based on RSRP. h _b,f,c (i,l) are used for power control adjustment of TPC.

The parameters used to determine the transmit power of an uplink channel/uplink signal are usually called power control parameters. The power control parameter set contains at least one power control parameter, that is, the uplink signal/uplink channel can be determined based on the power control parameter set of the uplink signal/uplink channel. The transmit power of the signal/uplink channel. The power control parameters in the power control parameter sets corresponding to different uplink channels/uplink signals may be completely different, or may be partially or completely the same.

Other parameters involved in the above formula (1), formula (2) and formula (3) and the calculation method of their values can refer to the protocol 3gpp 38.213, and will not be repeated here. It can be seen that the power control parameters of the uplink signal/uplink channel (such as the above-mentioned SRS, PUSCH or PUCCH) are configured through high-level signaling, or through a combination of high-level signaling and physical layer signaling, but each uplink signal/uplink The resources of the channel only correspond to one set of power control parameters. When a terminal device uses at least one panel to send uplink signals/uplink channels to multiple panels of a TRP (or to send uplink signals/uplink channels to multiple TRPs), the transmission paths of the terminal device to different panels (or different TRPs) are different. , the channel conditions are also different. If the same power control parameters are still used, the power utilization efficiency will be low. In other words, when the same uplink signal/uplink channel is associated with multiple power control parameter sets, how to determine the transmit power of the uplink signal/uplink channel to ensure the transmission of the uplink signal/uplink channel is an urgent problem to be solved .

The configuration information includes DCI, which is used to indicate that 2 pairs of TCI states are configured for the terminal device (for example, if the unified transmission configuration indicates the state type (also known as unifiedtci-StateType or unifiedtci-StateType-r17) configuration For uplink and downlink separation (SeparateULDL), one pair of TCI states includes a TCI state for DL and a TCI state for UL respectively; or, the DCI is used to indicate that two TCI states are configured for the terminal device (for example, if unifiedtci -State Type or unifiedtci-StateType-r17 is configured as joint uplink and downlink (JointULDL)), in which 1 TCI state can be used for DL and UL. In this application scenario, it can be regarded that the uplink signal/uplink channel is associated with multiple A power control parameter set, so that the terminal device can obtain multiple power control parameter sets associated with the uplink signal/uplink channel from the configuration information.

It should be noted that the configuration information mentioned in this application can be regarded as a general term, that is, the configuration information mentioned in this application may include one or more configuration information, and the one or more configuration information may be specifically used to configure the aforementioned 1 One or more of the ~5 items of information, or the one or more configuration information can also be used to configure other information (which can be understood as other information in addition to the aforementioned 1 to 5 items of information). Configure one or more of the aforementioned 1 to 5 items of information, or the one or more configuration information can also be used to configure other information (can be understood as other information in addition to the aforementioned 1 to 5 items of information). And the reception time of each configuration information by the terminal device can be the same or different, as shown in the full text.

The following is an example of how the terminal device obtains multiple power control parameter sets of PUSCH or PUCCH according to the configuration information.

In an example where the uplink channel is PUSCH, the terminal device receives configuration information from the network device. The configuration information is used to configure two SRS resource sets for the terminal device, and the first indication information in the configuration information indicates the transmission of the terminal device. The mode is space division transmission, and the DCI that schedules or triggers PUSCH in the configuration information indicates that the terminal equipment is configured with multiple transceiver nodes. In this case, it can be regarded that the PUSCH is associated with two power control parameter sets, so that the terminal device can obtain the two power control parameter sets associated with the PUSCH from the configuration information. Alternatively, the terminal device receives configuration information from the network device, and the configuration information includes an indication that PUSCH of configuration authorization type 1 is associated with two SRS resources (the two SRS resources correspond to different SRS resource sets). In this case, it can also be regarded that the PUSCH is associated with two power control parameter sets, so that the terminal device can obtain the two power control parameter sets associated with the PUSCH from the configuration information.

In an example where the uplink channel is PUCCH, the terminal device receives configuration information from the network device. The configuration information includes 2 power control parameter sets, and/or, the configuration information is used to configure 2 airspace information for the terminal device (such as spatial setting), and/or, the configuration information indicates 2 TCI states. In this case, it can be regarded that the PUCCH is associated with two power control parameter sets, so that the terminal device can obtain the two power control parameter sets associated with the PUCCH from the configuration information.

S202. The terminal device determines the transmit power of the uplink signal/uplink channel according to the first power control parameter set in the multiple power control parameter sets. Wherein, the first power control parameter set is one of the plurality of power control parameter sets.

In other words, when the uplink signal/uplink channel is associated with multiple power control parameter sets, the terminal device can determine one power control parameter set (i.e., the first power control parameter set) from the multiple power control parameter sets, and then determine the power control parameter set according to the first power control parameter set. The control parameter set determines the transmit power of the uplink signal/uplink channel.

For ease of understanding, the method of determining the first power control parameter set from multiple power control parameter sets will be described below, and then the determination of the transmit power of the uplink signal/uplink channel based on the first power control parameter set will be described.

In this application, the determination method of determining the first power control parameter set from multiple power control parameter sets includes but is not limited to the following methods:

Method 11: The network device indicates the first power control parameter set from the plurality of power control parameter sets.

In other words, when the uplink signal/uplink channel is associated with multiple power control parameter sets, the terminal device may receive indication information from the network device, where the indication information includes identification information of the first power control parameter set. Further, the terminal device determines the first power control parameter set from the plurality of power control parameter sets according to the indication information.

For example, uplink signal 1/uplink channel 1 is associated with power control parameter set A1 and power control parameter set A2. The terminal device receives indication information from the network device, and the indication information carries identification information of the power control parameter set A2. Further, the terminal device determines the power control parameter set A2 as the first power control parameter set based on the indication information.

Method 12: The terminal device determines the first power control parameter set from the plurality of power control parameters according to one or more power control parameters in the power control parameter set. That is to say, the first power control parameter set is determined based on one or more power control parameters in multiple power control parameter sets.

In a possible implementation, the first power control parameter set is specifically determined based on the transmit power corresponding to the multiple power control parameter sets, and the transmit power corresponding to the multiple power control parameter sets is determined by the multiple power control parameter sets. Determined by one or more centralized power control parameters.

In other words, the terminal device calculates the transmit power corresponding to each power control parameter set based on the power control parameters in each power control parameter set, and then the terminal device can calculate the transmit power corresponding to each power control parameter set from the multiple power control parameters. Centrally determine the first power control parameter set. In one possibility, the first power control parameter set is a power control parameter set corresponding to a first power value, and the first power value is a maximum value among the transmit powers corresponding to multiple power control parameter sets, that is, the The transmission power corresponding to one power control parameter set is the maximum value among the transmission powers corresponding to multiple power control parameter sets.

For example, uplink signal 1/uplink channel 1 is associated with power control parameter set A1 and power control parameter set A2. In this case, the terminal equipment calculates based on the power control parameter set A1 to transmit uplink signal 1/uplink channel 1 based on the power control parameter set A1, and its transmission power is P1; the terminal equipment calculates based on the power control parameter set A2 based on Power control parameter set A2 transmits uplink signal 1/uplink channel 1, and its transmit power is P2. In this case, if P2 is greater than P1, the terminal device determines the power control parameter set A2 as the first power control parameter set. Or, if P2 is greater than P1, the terminal equipment determines that the transmit power of uplink signal 1/uplink channel 1 is P2. That is to say, there is no need to determine the first power control parameter set from the multiple power control parameter sets, and determine the first power control parameter set according to The first power control parameter set determines the operation steps of the transmit power of the uplink signal 1/uplink channel 1.

In another possible implementation, the first power control parameter set is specifically determined based on the path loss values corresponding to the multiple power control parameter sets, and the path loss values corresponding to the multiple power control parameter sets are determined by multiple Determined by one or more power control parameters in the power control parameter set.

In other words, the terminal device determines the path loss value corresponding to each power control parameter set based on one or more power control parameters (such as a path loss reference signal) in each power control parameter set. Further, the terminal device can determine the path loss value corresponding to each power control parameter set according to each power control parameter set. The path loss value corresponding to the parameter set determines the first power control parameter set from the multiple power control parameter sets. In one possibility, the first power control parameter set is a power control parameter set corresponding to a first path loss value, and the first path loss value is a maximum value among path loss values corresponding to multiple power control parameter sets. That is to say, the path loss value corresponding to the first power control parameter set is the maximum value among the path loss values corresponding to the multiple power control parameter sets.

For example, uplink signal 1/uplink channel 1 is associated with power control parameter set A1 and power control parameter set A2, where the path loss reference signal in power control parameter set A1 is q _d1 , and the path loss reference signal in power control parameter set A2 is q _d2 . The terminal equipment calculates the path loss value corresponding to the power control parameter set A1 based on q _d1 as PL ₁ , and the terminal equipment calculates the path loss value corresponding to the power control parameter set A2 based on q _d2 is PL ₂ . If PL ₂ is greater than PL ₁ , the terminal device determines the power control parameter set A2 as the first power control parameter set.

After describing the method of determining the first power control parameter set from multiple power control parameter sets, the method of determining the transmit power of the uplink signal/uplink channel based on the first power control parameter set will be described below. In this application, the method of determining the transmit power of the uplink signal/uplink channel according to the first power control parameter set includes but is not limited to the following methods:

Method 21: The terminal device determines the transmit power of the uplink signal/uplink channel only based on the aforementioned first power control parameter set.

In other words, after the terminal device determines the first power control parameter set from multiple power control parameter sets according to the aforementioned method 11 or 12, the terminal device substitutes each power control parameter in the first power control parameter set into the communication protocol. From the defined transmission power calculation formula of the uplink signal/uplink channel, the transmission power of the uplink signal/uplink channel is calculated.

Method 22: The terminal equipment determines the transmit power of the uplink signal/uplink channel based on the average path loss value and the aforementioned first power control parameter set. The average path loss value is the average of the path loss values corresponding to multiple power control parameter sets.

In other words, the terminal device determines the path loss value corresponding to each power control parameter set based on one or more power control parameters (such as the path loss reference signal) in each power control parameter set, and corresponding The road loss value is calculated to obtain the average road loss value. After the terminal equipment determines the first power control parameter set from multiple power control parameter sets according to the aforementioned method 11 or 12, the terminal equipment sets the average path loss value and the first power control parameter set except for the path loss value ( Or understood as other power control parameters (except for the path loss reference signal), substitute them into the transmit power calculation formula of the uplink signal/uplink channel defined in the communication protocol, and calculate the transmit power of the uplink signal/uplink channel.

For example, uplink signal 1/uplink channel 1 is associated with power control parameter set A1 and power control parameter set A2, where the path loss reference signal in power control parameter set A1 is q _d1 , and the path loss reference signal in power control parameter set A2 is q _d2 . The terminal equipment calculates the path loss value corresponding to the power control parameter set A1 based on q _d1 as PL ₁ , the terminal equipment calculates the path loss value corresponding to the power control parameter set A2 as PL ₂ based on q _d2 , and the average path loss value is The terminal device determines the first power control parameter set according to the aforementioned method 11 or 12. The first power control parameter set may be a power control parameter set indicated by the network device, or may be a power control parameter set corresponding to the maximum transmit power, or It can be the power control parameter set corresponding to the maximum path loss value. Furthermore, the terminal equipment will average the path loss value Other power control parameters in the first power control parameter set except the path loss reference signal are substituted into the transmission power calculation formula of the uplink signal/uplink channel defined in the communication protocol, and the transmission power of the uplink signal/uplink channel is calculated.

By implementing the power determination method shown in Figure 2, when the uplink signal/uplink channel is associated with multiple power control parameter sets, the terminal device can still determine the transmit power of the uplink signal/uplink channel, thereby ensuring that the uplink signal/uplink channel transmission.

If the antenna port that transmits the uplink signal/uplink channel corresponds to at least one antenna port group, in this case, how does the terminal device determine the transmit power of the antenna port in each antenna port group to improve the transmission of the uplink signal/uplink channel? Reliability is an issue that needs to be solved urgently. Based on this, this application also provides a schematic flow chart of another power determination method, as shown in Figure 3. The execution subject of the method shown in Figure 3 may be a terminal device, or a chip in the terminal device. Figure 3 takes the terminal device as the execution subject of the method as an example for illustration. As shown in Figure 3, the power determination method includes the following steps.

S301. The terminal device determines the first transmission power of the antenna port group for sending the uplink signal/uplink channel based on the network configuration information.

In a possible implementation manner of determining the first transmit power, the uplink signal/uplink channel corresponds to at least one antenna port group. After the terminal device determines the transmit power of the uplink signal/uplink channel based on the power determination method shown in Figure 2, the terminal device can allocate the transmit power to each antenna port group based on the network configuration information to obtain each The first transmit power corresponding to each antenna port group. That is to say, in this example, the network configuration information can be understood as the allocation method of the network configuration to allocate the transmission power of the uplink signal/uplink channel to each antenna port group, including but not limited to average allocation.

In another possible implementation of determining the first transmit power, the terminal device may also calculate the first transmit power for each antenna port group to send uplink signals/uplink channels based on the power control parameter set corresponding to each antenna port group. That is to say, in this implementation manner, the network configuration information can understand the power control parameter set corresponding to the antenna port group. The terminal device substitutes each power control parameter in the power control parameter set corresponding to the antenna port group into the transmission power calculation formula of the uplink signal/uplink channel defined by the communication protocol to calculate the first transmission power of the antenna port group. For the description of the power control parameter set, please refer to the description of the power control parameter set in S201, which will not be described again here.

It should be noted that different antenna port groups can be associated with different SRS resource sets, and different SRS resource sets correspond to different power control parameter sets. That is to say, different antenna port groups can correspond to different power control parameter sets. The terminal device passes The configuration information obtains multiple SRS resource sets associated with the uplink signal/uplink channel. It can be regarded that the terminal device also obtains the power control parameter set corresponding to each antenna port group through the configuration information. Among them, the way for the terminal device to obtain multiple power control parameter sets associated with the uplink signal/uplink channel (that is, the power control parameter set corresponding to each antenna port group) can be found in the aforementioned S201 for obtaining multiple power control parameter sets associated with the uplink signal/uplink channel. The relevant description of the power control parameter set will not be repeated here. Alternatively, each antenna port group can be associated with different SRS resources, where different SRS resources originate from different SRS resource sets. It can be understood that the above-mentioned antenna port group may be a port of an SRS, that is, the antenna port group is a port of its associated SRS resource. It can be understood that the uplink channel may be PUSCH.

S302. The terminal device performs power scaling on the first transmission power according to the scaling factor corresponding to the antenna port group to obtain the second transmission power.

In codebook-based uplink signal/uplink channel transmission, the terminal device will power scale the first transmit power of each antenna port group according to the scaling factor corresponding to the antenna port group to obtain the second transmit power of each antenna port group. . In other words, the second transmit power of a certain antenna port group is: the product of the first transmit power of the antenna port group and the scaling factor of the antenna port group.

Factors that affect the scaling factor include: whether the terminal device is configured with uplink full power transmission (also known as ul-FullPowerTransmission), and what kind of uplink full power transmission the terminal device is configured with. The following describes the scaling factors of the antenna port group in the following four situations:

Scenario 1: The terminal device is not configured for uplink full power transmission.

In this case, the scaling factor of the antenna port group is: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports supported by the terminal device in the SRS resource corresponding to the antenna port group. Alternatively, the scaling factor of the antenna port group is: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports in one SRS resource of the SRS resource set corresponding to the antenna port group supported by the terminal device. Alternatively, the scaling factor of the antenna port group is: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports of one SRS resource supported by the terminal device; optionally, one of the SRS resources corresponds to the antenna port The SRS resource set corresponding to the group.

Scenario 2: The terminal device is configured for uplink full power transmission, and the type of uplink full power transmission configured is full power mode 1 (also known as fullpowerMode1).

The scaling factor of an antenna port group is: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports supported by the terminal device in the SRS resource corresponding to the antenna port group. Alternatively, the scaling factor for the antenna port group is: The ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports in one SRS resource of the SRS resource set corresponding to the antenna port group supported by the terminal device. Alternatively, the scaling factor of the antenna port group is: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports of one SRS resource supported by the terminal device, where one SRS resource corresponds to the SRS corresponding to the antenna port group Resource set.

Scenario 3: The terminal device is configured for uplink full power transmission, and the type of uplink full power transmission configured is full power mode 2 (also known as fullpowerMode2).

The scaling factor of the antenna port group is: For the full-power transmit precoding matrix indicator (TPMI) reported by the terminal device, the scaling factor is 1. Or, for TMPI that is not a full-power TPMI reported by the terminal device, if an SRS resource set is configured with multiple SRS resources, the scaling factor is the number of non-zero ports and the SRS indicated by the DCI SRS resource indicator (SRS resource indicator, SRI) field. The ratio of the number of ports of the resource; alternatively, the scaling factor is the ratio of the number of non-zero ports to the number of ports of the SRS resource indicated by configured grant Type 1. For TMPI that is not the full-power TPMI reported by the terminal device, if an SRS resource set is configured with 1 SRS resource, the scaling factor is the ratio of the number of non-zero ports to the number of ports of SRS resources in the SRS resource set.

The scaling factor of the antenna port group is: if the number of ports of the SRS resource indicated by the DCI SRI field is 1, or if the number of ports of the SRS resource indicated by the configured grant Type 1 is 1, or if an SRS resource set is configured with 1 For SRS resources and the number of ports is 1, the scaling factor is 1.

Scenario 4: If the terminal device is configured with uplink full power transmission (also known as ul-FullPowerTransmission), and the type of uplink full power transmission configured is full power mode (also known as fullpowerMode), then the scaling factor of the antenna port group is 1 .

Below, a schematic explanation will be given, taking the scaling factor of an antenna port group as: the ratio of the number of non-zero antenna ports in the antenna port group to the maximum number of SRS ports supported by the terminal device in the SRS resource corresponding to the antenna port group as an example. It should be noted that the non-zero antenna ports mentioned in this application are the antenna ports in the antenna port group that transmit uplink signals/uplink channels with non-zero power, as shown in the full text.

Exemplarily, the antenna ports used for uplink signal 1/uplink channel 1 transmission include: antenna port 0 to antenna port 3, where antenna port 0 and antenna port 2 belong to antenna port group 1, and antenna port 1 and antenna port 3 belong to The maximum number of SRS ports supported by terminal devices in antenna port group 2, antenna port group 1 and antenna port group 2 is all 2, and according to the implementation described in S301, the first transmit power of antenna port group 1 is calculated to be P1, The first transmit power of antenna port group 2 is P2. In this case, if the precoding matrix indicated by DCI is [1 1 1 0] ^T , that is, the DCI indicates that antenna port 0 to antenna port 2 are all non-zero antenna ports, and antenna port 3 transmits uplink signals with zero power. /Antenna port for the upstream channel. It can be inferred from this that the scaling factor corresponding to antenna port group 1 is 1, and the second transmission power of antenna port group 1 is P1. The scaling factor corresponding to antenna port group 2 is The second transmit power of antenna port group 2 is

S303. The terminal device determines the transmission power of the non-zero antenna port in the antenna port group to send the uplink signal/uplink channel based on the second transmission power.

After the terminal device determines the second transmit power of the antenna port group, the second transmit power is allocated according to the preset power allocation principle. The transmit power is allocated to the non-zero antenna ports in the antenna port group. That is to say, the sum of the transmit power of the non-zero antenna ports in the antenna port group transmitting uplink signals/uplink channels is equal to the second corresponding to the antenna port group. Transmit power.

In a possible implementation, the terminal device may evenly distribute the second transmit power to non-zero antenna ports in the antenna port group. That is to say, the transmit power of each non-zero antenna port in the antenna port group is: the ratio of the second transmit power corresponding to the antenna port group and the number of non-zero antenna ports in the antenna port group.

For example, if the second transmit power of antenna port group 1 is P1, and the non-zero antenna ports included in antenna port group 1 are: antenna port 0 and antenna port 2, then the transmit power of antenna port 0 is The transmit power of antenna port 2 is If the second transmit power of antenna port group 2 is The non-zero antenna ports included in antenna port group 2 are: antenna port 1, then the transmit power of antenna port 1 is

It can be seen that when the uplink signal/uplink channel is transmitted through at least one antenna port group, the terminal device can perform power scaling on the uplink signal/uplink channel at the granularity of the antenna port group, thereby obtaining greater transmission power and improving the uplink signal/uplink channel. The transmission reliability of the channel. For example, the uplink signal/uplink channel corresponds to antenna port group 1 and antenna port group 2, where antenna port group 1 includes: antenna port 0 (non-zero antenna port), antenna port 1 (non-zero antenna port); antenna port group 2 includes : Antenna port 2, antenna port 3. If the transmit power of antenna port group 1 is P1, the transmit power of antenna port group 2 is P2, and P1 is greater than P2; in this case, if power scaling is not performed by antenna port group, due to the antenna corresponding to the uplink signal/uplink channel There are only 1/2 non-zero antenna ports in the port, then the total transmission power of the uplink signal/uplink channel is (P1+P2)/2, and the total transmission power of the non-zero antenna ports (i.e., antenna port 0 and antenna port 1) The power is (P1+P2)/2; if the power of the uplink signal/uplink channel is scaled using the antenna port group as the granularity in the method provided by this application, then the total transmit power of the uplink signal/uplink channel is P1, not The total transmit power of zero antenna ports (i.e., antenna port 0 and antenna port 1) is P1. It can be seen that greater transmission power can be obtained through the power scaling mechanism provided by this application, thereby improving the transmission reliability of the uplink signal/uplink channel.
