In practical applications, the connections between the above devices may be wireless connections or wired connections.

Referring to fig. 2, fig. 2 is a flowchart of an energy saving signal transmission method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. the terminal determines the sending power of the uplink signal according to the coherent transmission capability of the terminal;

202. and the terminal transmits the uplink signal according to the transmission power.

Wherein the coherent transmission capability may include at least one of non-coherent transmission, partially coherent transmission, and fully coherent transmission. And the coherent transmission capability of the terminal may be the antenna coherent transmission capability of the terminal

The uplink signal may be a Physical Uplink Shared Channel (PUSCH) in a codebook-based uplink transmission scheme, or may be a PUSCH in a non-codebook transmission scheme, or may be a PUSCH in a transmit diversity transmission scheme, or may be a PUSCH in another multi-antenna transmission scheme, or may be another uplink signal transmitted using multiple antennas. For example, a Physical Uplink Control Channel (PUCCH), an Uplink Demodulation Reference Signal (DMRS), an Uplink Sounding Reference Signal (SRS), or the like.

In the embodiment of the invention, the terminal determines the sending power of the uplink signal according to the coherent transmission capability of the terminal; and the terminal transmits the uplink signal according to the transmission power. Thus, the transmission power is determined according to the coherent transmission capability of the terminal, so that the use efficiency of the transmission power can be improved

In addition, the transmitting the uplink signal according to the transmission power may be transmitting the uplink signal according to the transmission power, or may be transmitting the uplink signal according to the allocated power after allocating the transmission power according to a certain rule, for example: if the uplink signal and other uplink signals are transmitted on the same resource, power sharing may be performed on the multiple uplink signals. That is, in the embodiment of the present invention, the transmission power is not limited to the actual transmission power of the uplink signal. In the embodiment of the present invention, a manner of transmitting the uplink signal according to the transmission power is not limited.

In the embodiment of the invention, the sending power of the uplink signal is determined according to the coherent transmission capability of the terminal, so that the use efficiency of the sending power can be improved. In addition, the terminal may be capable of full power transmission in a low rank (rank) mode, but the terminal may have maximum transmission power in a low rank (rank) mode in which a plurality of antenna ports are arranged. Meanwhile, the sending power of the terminal can be more effectively adjusted, and the performance of the terminal and the system performance are improved.

As an optional implementation manner, the coherent transmission capability includes:

a coherence transmission capability supported by the terminal; or

The coherent transmission capability reported by the terminal to the network side device may be a coherent transmission capability supported by the terminal.

In this embodiment, it may be achieved that the coherent transmission capability of the terminal may be a coherent transmission capability supported by the terminal itself, or the coherent transmission capability of the terminal is a coherent transmission capability supported by the terminal reported by the terminal, or the coherent transmission capability of the terminal is a coherent transmission capability determined according to the indication signaling of the base station. And the behavior of the terminal may further include: and receiving the indication signaling sent by the base station.

The indication signaling is used for indicating the terminal to determine the sending power of the uplink signal by adopting the coherence transmission capability lower than the coherence transmission capability supported by the terminal; or

In this embodiment, the indication signaling that can implement the network side device may be the following signaling: and indicating the terminal to adopt a transmission mode lower than the coherent transmission capability of the terminal to carry out uplink transmission. For example: the indication signaling indicates the terminal to adopt a transmission mode lower than the coherent transmission capability of the terminal to carry out uplink transmission indication signaling, but does not carry specific coherent transmission capability. The terminal receives the indication signaling, and determines the sending power of the uplink signal with the coherent transmission capability lower than the coherent transmission capability of the terminal. Assuming that the maximum coherent transmission capability of the terminal is full coherent transmission, the coherent transmission capability of step 201 is partial coherent transmission.

In addition, in this embodiment, it may also be implemented that the indication signaling of the network side device may be the following signaling: the indication signaling instructing the terminal to determine the transmission power of the uplink signal with the coherent transmission capability lower than the coherent transmission capability of the terminal is to indicate the coherent transmission capability of step 201 in an implicit manner. For example: the indication signaling indicates that the terminal determines the sending power of the uplink signal by adopting the coherent transmission capability lower than the coherent transmission capability of the terminal, but does not carry the specific coherent transmission capability. The terminal receives the indication signaling, and determines the sending power of the uplink signal with the coherent transmission capability lower than the coherent transmission capability of the terminal. Assuming that the maximum coherent transmission capability of the terminal is full coherent transmission, step 201 determines the transmission power of the uplink signal by using partial coherent transmission.

In addition, the transmission capability indication information may indicate a specific coherent transmission capability, or indicate that a non-coherent transmission capability is adopted as the coherent transmission capability in step 201.

For example: the network side equipment can send an indication signaling to indicate that the UE with the full coherent transmission capability adopts the mode that the maximum coherent transmission is the partial coherent transmission to send the uplink signal; in this way, the terminal determines the uplink transmission power based on the manner of the partially coherent transmission capability.

For another example, the indication signaling may indicate that the terminal does not perform coherent transmission. In this way, even if the terminal has the capability of partially coherent transmission or fully coherent transmission, the terminal determines the uplink transmission power based on the method for determining the uplink transmission power corresponding to the non-coherent transmission capability, that is, the non-coherent transmission capability.

For another example, the network side device may send an indication signaling indicating that the UE with full coherent transmission capability determines the transmission power of the uplink signal in a partial coherent transmission manner; in this manner, the terminal determines the uplink transmission power based on the partial coherence transmission capability.

For another example, the indication signaling may instruct the terminal to determine the transmission power of the uplink signal with the non-coherent transmission capability. In this way, even if the terminal has the capability of partially coherent transmission or fully coherent transmission, the terminal determines the uplink transmission power based on the method for determining the uplink transmission power corresponding to the non-coherent transmission capability, that is, the non-coherent transmission capability.

Optionally, the capability indication information is used to indicate that the terminal performs uplink transmission of a first type using a first coherent transmission capability; or

The capability indication information is used for indicating the terminal not to adopt a first coherent transmission capability to carry out first type uplink transmission; or

For example, the network side device may send an indication signaling indicating that the UE with full coherent transmission capability uses the maximum coherent transmission mode as the partial coherent transmission mode to send the uplink signal; in this way, the terminal determines the uplink transmission power based on the manner of the partially coherent transmission capability.

For example, the network side device may send an indication signaling indicating that the UE with full coherent transmission capability determines the transmission power of the uplink signal in a partially coherent transmission manner; in this manner, the terminal determines the uplink transmission power based on the partial coherent transmission capability.

For another example, the indication signaling may instruct the terminal to determine the transmission power of the uplink signal with the non-coherent transmission capability. In this way, even if the terminal has the capability of partially coherent transmission or fully coherent transmission, the terminal determines the uplink transmission power based on the determination method of the uplink transmission power corresponding to the non-coherent transmission capability, that is, the non-coherent transmission capability.

Optionally, the indication signaling is configured to instruct the terminal to transmit the first type of uplink signal in a transmission mode lower than the coherent transmission capability supported by the terminal; or

The indication signaling is used for indicating the terminal to determine the sending power of the first type of uplink signal by adopting the coherent transmission capability lower than the coherent transmission capability supported by the terminal.

In this embodiment, the indication signaling of the network side device may be the following signaling: and indicating the terminal to adopt a transmission mode lower than the coherent transmission capability of the terminal to carry out the indication signaling of the first type of uplink signal transmission. For example: the indication signaling indicates the terminal to adopt a transmission mode lower than the coherent transmission capability of the terminal to carry out uplink transmission indication signaling, but does not carry specific coherent transmission capability. The terminal receives the indication signaling, and determines the transmission power of the uplink signal with a coherent transmission capability lower than that of the terminal. Assuming that the maximum coherent transmission capability of the terminal is full coherent transmission, the coherent transmission capability of step 201 is partial coherent transmission.

In this embodiment, it can also be implemented that the indication signaling of the network side device base station may be the following signaling: and indicating signaling for indicating the terminal to determine the sending power of the first type of uplink signal by adopting the coherent transmission capability lower than the coherent transmission capability of the terminal. For example: the indication signaling indicates the terminal to determine the sending power of the uplink signal by using a coherence transmission capability lower than the coherence transmission capability of the terminal, but does not carry a specific coherence transmission capability. The terminal receives the indication signaling, and determines the sending power of the uplink signal with the coherent transmission capability lower than the coherent transmission capability of the terminal. Assuming that the maximum coherent transmission capability of the terminal is partially coherent transmission, step 201 determines the transmission power of the uplink signal by using non-coherent transmission.

It should be noted that, in this embodiment of the present invention, the type of the first type of uplink signal may be a type of an uplink signal indicated by a network side device. For example, the first type of uplink signal is a codebook-based PUSCH, that is, the network side device may instruct the terminal to transmit the codebook-based PUSCH in a manner lower than the coherent transmission capability of the terminal. Accordingly, the terminal may determine the transmission power of the PUSCH based on the codebook using the coherent transmission capability corresponding to the indication signaling indicated by the network side device.

In addition, the type of the first type of uplink signal may be a predefined type of uplink signal. For example, the network side device sends one of the indication signaling to the terminal. The network side equipment and the terminal have agreed in advance that the indication signaling corresponds to a PUSCH based on a codebook. The terminal may determine the transmission power of the PUSCH based on the codebook according to the coherent transmission capability corresponding to the indication signaling.

Optionally, the indication signaling includes:

codebook subset restriction signaling of the uplink signal;

The codebook subset of the codebook subset restriction signaling is configured as fully coherent, partially coherent and non-coherent, and then the maximum coherent transmission capability of the terminal is the fully coherent transmission capability.

For example: when the network side device configures a codebook Subset restriction signaling codebook Subset (codebook Subset) as "non-Coherent", all antennas corresponding to the terminal cannot perform Coherent transmission (i.e. corresponding to "non-Coherent transmission" capability); if the network side device can only configure codebook Subset restriction signaling codebook Subset as "partial Coherent And Non-Coherent (partial And Non Coherent)", then partial antennas corresponding to the terminal may be coherently transmitted (i.e. corresponding to "partial Coherent transmission" capability); if the network side device configures codebook Subset restriction signaling codebook Subset as "fully Coherent, partially Coherent, and Non-Coherent" (full And Partial And Non-Coherent ", all antennas corresponding to the terminal may transmit coherently (i.e. corresponding to" fully Coherent transmission "capability).

As an optional implementation, the method further comprises:

The first signaling may be transmitted before step 201, or may be transmitted after step 202, which is not limited herein.

In addition, the first signaling may be a dedicated signaling specifically indicating the coherent transmission capability of the terminal. Or may be an implicit indication. E.g., implicitly carried by other signaling. For example:

the first signaling comprises indication information, the indication information comprises full coherence, partial coherence or noncoherence, and the indication information is used for configuring codebook subset restriction signaling by a network side device so as to implicitly indicate coherent transmission capability supported by the terminal through the codebook subset restriction signaling.

In this embodiment, it may be achieved that the terminal indicates its antenna coherent transmission capability through the codebook subset restriction signaling that it supports. For example, in an NR system, a terminal may send its antenna coherence transmission capability by signaling:

when the value of the pusch Coherent transmission (pusch-Trans Coherence) capability indication reported by the terminal is "non Coherent", the base station can only configure the codebook Subset restriction signaling codebook Subset as "non Coherent", that is, the codebook Subset only corresponds to the codeword of the non-Coherent transmission, which means that all antennas of the terminal cannot perform Coherent transmission (corresponding to the maximum transmission capability being "non-Coherent transmission" capability);

when the value of the pusch-Trans Coherence capability indication reported by the terminal is "partial Non Coherent", the base station can only configure the codebook Subset restriction signaling codebook Subset as "partial And Non Coherent" or "Non Coherent", that is, the codebook Subset only corresponds to codewords of partial Coherent transmission And Non-Coherent transmission, which means that partial antennas of the terminal can perform Coherent transmission (the maximum Coherent transmission capability corresponding to the terminal is "partial Coherent transmission" capability);

when the value of the pusch-Trans Coherence capability indication reported by the terminal is "full Coherence", the base station can only configure the codebook Subset restriction signaling codebook Subset as "full And Partial And Non-Coherent", or "Partial And Non-Coherent" or "Non-Coherent", that is, the codebook Subset only corresponds to all codewords, which means that all antennas of the terminal can transmit coherently (the maximum Coherent transmission capability corresponding to the terminal is "full Coherent transmission" capability).

It should be noted that the above table is only an example, and in some embodiments, the name of the first signaling may include coherent transmission, but only include the above information content, i.e., fully coherent, partially coherent, or non-coherent.

It should be noted that different definitions and requirements for coherent transmission of antennas may be possible in different protocols. In the embodiment of the present invention, the definition of the coherent transmission of the terminal antenna (i.e., the coherent transmission of the terminal) may be defined according to an applicable system. For example: in the NR system Release R15, the protocol specifies coherent transmission for two antenna ports as follows (3 GPP protocol TS38.101-1-f20, NR; user Equipment (UE) radio transmission and reception; part 1:

for coherent transmission (coherent) Uplink (UL) Multiple-Input Multiple-Output (MIMO), table 6.4d.4-1 lists the maximum allowed errors for the relative power error and phase difference measured in the time window from the last SRS transmission to the measurement with one SRS at any time slot when the power of any one uplink transmission antenna port is greater than 0 dB.

For example: in Table 6.4D.4-1, maximum allowable difference of relative phase and power errors in a given slot compared to the Maximum allowable relative phase error and relative power error of any slot of the last SRS transmission can be shown in Table 1:

table 1:

as an optional implementation manner, the determining, by the terminal, the transmission power of the uplink signal according to the coherent transmission capability of the terminal includes:

The transmission power control rule may be predefined in a protocol, or pre-negotiated between the network side device and the terminal, or configured to the terminal by the network side device, which is not limited in this respect.

The above-mentioned determining, by the terminal, the transmission power of the uplink signal according to the predefined transmission power control rule of the uplink signal and using the coherence transmission capability of the terminal may also be understood as determining the transmission power of the uplink signal according to the predefined transmission power control rule of the uplink signal and the coherence transmission capability of the terminal. In this embodiment, the transmission power can be determined by the above-described predefined transmission power control rule, so that the power use efficiency can be further improved. And determining the transmission power of the uplink signal according to the coherent transmission capability of the terminal, the number of activated antenna ports corresponding to the transmission of the uplink signal, and the number of first antenna ports, which may further maximize the utilization of the transmission power of the terminal, for example: so that the maximum transmit power cannot be reached for low rank transmissions. In addition, in this embodiment, the transmission power of the terminal can be adjusted more efficiently, and the performance of the terminal and the system performance can be improved.

In one implementation, the determining, by the terminal, the transmission power of the uplink signal according to a predefined transmission power control rule of the uplink signal by using the coherent transmission capability of the terminal includes:

Wherein, above, X > = Y, Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be derived according to the uplink transmission power control rule defined by the protocol.

The transmission of the uplink signal is transmission of a codeword corresponding to the maximum coherent transmission capability of the terminal, where the number of transmission streams may be X, and the number of transmission streams is rank-X, and the transmission of the uplink signal is transmission using the codeword corresponding to the maximum coherent transmission capability of the terminal; or the transmission of the uplink signal is transmission of a codeword corresponding to the maximum coherent transmission capability of the terminal, and the number of transmission streams may be X, and the transmission of the uplink signal is transmission of a rank-X corresponding to the maximum coherent transmission capability of the terminal, because the codeword may carry stream number information. That is, when the transmission of the uplink signal is rank-X corresponding to the maximum coherent transmission capability of the terminal, the terminal uniformly distributes the first uplink transmission power P to each active antenna port corresponding to the uplink signal transmission as the uplink transmission power of each antenna port.

Preferably, Y =1.Rank-X refers to the number of transmission streams of the uplink signal. For PUSCH based on a codebook, X corresponds to a precoding matrix corresponding to the PUSCH and the number of layers (layer number) in the transmission stream number indication information, which are indicated by the network side device for the terminal.

Preferably, the "transmission of rank-X corresponding to the maximum coherent transmission capability of the terminal" may be "transmission of precoding matrix being the precoding matrix of rank-X corresponding to the maximum coherent transmission capability of the UE". For example, the uplink signal is a PUSCH based on a codebook, the maximum coherent transmission capability of a terminal is non-coherent transmission, and if Y =1, the terminal uniformly distributes the transmission power P to each active antenna port of the PUSCH under all ranks. For another example, the uplink signal is a PUSCH based on a codebook, the maximum coherent transmission capability of one terminal is partial coherent transmission, and if Y =2, the terminal uniformly distributes the transmission power P to each active antenna port of the PUSCH when the precoding matrix is a partial coherent transmission codeword and the number of streams is greater than or equal to 2.

In addition, in the above embodiment, the predefined uplink signal transmission power control rule may further include: in the second case described above, for example: when the transmission of the uplink signal is corresponding to other transmissions (i.e. not transmission of rank-X corresponding to the maximum coherent transmission capability of the terminal), the terminal scales the first uplink transmission power P according to the first scaling factor and then uniformly distributes the first uplink transmission power P to each activated antenna port of the uplink signal.

It should be noted that the number of active antenna ports corresponding to the uplink signal transmission may refer to the number of antenna ports to which data mapping exists during the uplink signal transmission. Taking the uplink signal as the PUSCH in the codebook-based uplink transmission mode as an example, the number of the activated antenna ports is the number of antenna ports with non-zero elements in the precoding matrix.

In another implementation manner, the determining, by the terminal, the transmission power of the uplink signal according to a predefined transmission power control rule of the uplink signal by using the coherent transmission capability of the terminal includes:

under a third condition that the number of antenna ports corresponding to the transmission of the uplink signal is equal to the maximum number of antenna ports of the uplink signal transmission supported by the terminal, the transmission of the uplink signal is transmission under a code word corresponding to the maximum coherent transmission capability of the terminal, and the number of transmission streams is X, the terminal uniformly distributes first uplink transmission power to each activated antenna port corresponding to the transmission of the uplink signal, wherein X is an integer greater than or equal to Y, and Y is a predefined integer; and/or

It should be noted that, in this embodiment, reference may be made to the description of the above embodiment for determining the transmission power, which is not described herein again. In the two implementation manners, the values of X are the same or different, and the values of Y may be the same or different.

In this embodiment, when the number of antenna ports corresponding to the transmission of the uplink signal is equal to the maximum number of antenna ports of the uplink signal transmission supported by the UE, and the transmission of the uplink signal is the uplink signal transmission of rank-X corresponding to the maximum coherent transmission capability of the UE, the terminal may uniformly distribute the first transmission power P to each activated antenna port corresponding to the uplink signal transmission, as the uplink transmission power of each antenna port. Where X > = Y, Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be derived according to the uplink transmission power control rule defined by the protocol.

Preferably, Y =1.Rank-X refers to the number of transmission streams of the uplink signal. For PUSCH based on codebook, X corresponds to the number of layers (or called number of streams, or called number of layers) in the precoding matrix and transmission stream number indication information corresponding to the PUSCH that the base station indicates for the terminal.

Preferably, the "transmission of rank-X corresponding to the maximum coherent transmission capability of the terminal" may be "transmission of precoding matrix being the precoding matrix of rank-X corresponding to the maximum coherent transmission capability of the terminal". For example, the uplink signal is a codebook-based PUSCH, the maximum coherent transmission capability of one UE is non-coherent transmission, the maximum number of antenna ports of the uplink signal transmission supported by the UE is 4,y =1, and the UE uniformly distributes the transmission power P to each active antenna port of the PUSCH under all ranks in the codebook-based PUSCH with 4 antenna ports.

It can also be implemented that the predefined uplink signal transmission power control rule further includes: and when the transmission of the uplink signal corresponds to other transmissions, the terminal scales P according to a first scaling factor and then uniformly distributes the P to each activated antenna port of the uplink signal.

Optionally, in the above embodiment, the first scaling factor is: 1 and a minimum value of a ratio of the number of activated antenna ports, wherein the ratio of the number of activated antenna ports is a ratio of a first number of activated antenna ports to a second number of activated antenna ports, the first number of activated antenna ports is the number of activated antenna ports corresponding to the uplink signal transmission, and the second number of activated antenna ports is: the terminal activates the number of antenna ports according to the number of transmission under the condition of the codeword corresponding to the maximum coherent transmission capability with the transmission stream number of Y, wherein Y is a predefined integer.

For example: the first scaling factor may be: the smaller value between the ratio of the number of activated antenna ports corresponding to the uplink signal transmission and the number of activated antenna ports of the terminal during the uplink signal transmission according to rank-Y corresponding to the maximum coherent transmission capability of the terminal and 1. For example, the uplink signal is a PUSCH based on a codebook, the maximum coherent transmission capability of one UE is partial coherent transmission, Y =2, and then the UE does not scale P when the precoding matrix is a partial coherent transmission codeword and the number of streams is equal to 2; when the precoding matrix is a partial coherent transmission code word and the number of streams is 1, the first scaling factor is 1/2; when the precoding matrix is a non-coherent transmission codeword and the number of streams is 1, the first scaling factor is 1/4.

Example one: the uplink signal is a PUSCH based on a codebook, and Y =1.

The first scaling factor is shown in table 2 below, wherein the manner in which the terminal will not scale the transmission power P can be considered as corresponding to the manner in which the first scaling factor is 1:

table 2:

another example is: the first scaling factor may be: the number between the ratio of the number of activated antenna ports corresponding to the uplink signal transmission and the number of activated antenna ports of the terminal during uplink signal transmission according to rank-Y under the maximum coherent transmission capability of the UE under the maximum number of antenna ports corresponding to the uplink signal transmission supported by the terminal is smaller than 1. For example, the uplink signal is a PUSCH based on a codebook, the maximum coherent transmission capability of a terminal is a partially coherent transmission, the maximum number of antenna ports for uplink signal transmission supported by the terminal is 4,y =1, then the terminal activates 2 antenna ports (the number of activated antenna ports corresponding to a precoding matrix of rank-2 for partially coherent transmission under the maximum coherent transmission capability of the UE) during uplink signal transmission according to rank-Y under the maximum coherent transmission capability of the UE under the maximum number of antenna ports supported by the terminal, and since the number of activated antenna ports corresponding to the terminal when the precoding matrix is an incoherent transmission codeword and the number of streams is equal to 4 is 4, the first scaling factor of the UE is 1 when the precoding matrix is an incoherent transmission codeword and the number of streams is equal to 4.

Example two: the uplink signal is a PUSCH based on a codebook, and Y =1.

The first scaling factor is as shown in table 3, wherein the way that the terminal will not scale the transmission power P can be considered as the way corresponding to the first scaling factor being 1:

table 3:

in an implementation manner, the determining, by the terminal, the transmission power of the uplink signal according to the coherent transmission capability of the terminal, the number of activated antenna ports corresponding to the transmission of the uplink signal, and the number of first antenna ports may include:

The number of activated antenna ports corresponding to the uplink signal transmission may be the number of antenna ports with data mapping when the uplink signal transmission is performed. Taking the uplink signal as the PUSCH in the codebook-based uplink transmission mode as an example, the number of the activated antenna ports is the number of antenna ports with non-zero elements in the precoding matrix. In addition, when the uplink signal is a PUSCH based on a codebook, optionally, the terminal determines, according to a precoding matrix corresponding to the PUSCH transmission and the transmission stream number indication information, the number of active antenna ports corresponding to the PUSCH transmission.

In this embodiment, the total transmission power can be determined, and the total transmission power is uniformly distributed to the activated antenna ports corresponding to the uplink signal transmission, so that the use performance of the transmission power of the terminal is further improved.

wherein min represents a minimum value, P represents a first uplink transmission power, S represents the number of antennas in a coherent transmission group when the coherent transmission capability of the terminal is partially coherent transmission, M represents the number of first antenna ports, and R represents the number of activated antenna ports corresponding to transmission of the uplink signal.

For example: min { A, B } represents the smaller of A and B,/represents the division number.

It should be noted that, when the coherent transmission capability of the terminal is non-coherent transmission, the total transmission power is equal to P, so that the transmission power of the uplink signal can be determined according to the coherent transmission capability of the terminal only.

In the embodiment, different powers can be calculated according to different coherent transmission capabilities, so that the maximum transmission power can be reached during uplink low rank transmission. Meanwhile, the sending power of the terminal can be more effectively adjusted, and the performance of the terminal and the system performance are improved.

in the case that the coherent transmission capability of the terminal is full coherent transmission, the second power scaling factor is equal to min {1,R/M };

In this embodiment, the total transmit power may be calculated by multiplying P by the second scaling factor β, that is, determining the total transmit power as follows:

for a UE with coherent transmission capability "non-coherent transmission", β =1;

for a UE with coherent transmission capability of "partial coherent transmission", β is equal to min {1,S × R/M };

for a UE with coherent transmission capability "full coherent transmission", the total transmit power is β = min {1,R/M }.

Also, in this embodiment, it is possible to calculate different powers according to different coherent transmission capabilities, so that the maximum transmission power can be reached at the time of uplink low rank transmission. Meanwhile, the sending power of the terminal can be more effectively adjusted, and the performance of the terminal and the system performance are improved.

Taking the UE of the NR system as an example, the partially coherent transmission can only be a capability of the terminal when the maximum number of antenna ports of the codebook-based PUSCH transmission supported by the terminal is 4 (i.e. the maximum number of antenna ports of the SRS resource of one codebook-based PUSCH supported by the terminal is 4), and in the above embodiment, the β of the "partially coherent transmission" UE is equal to min {1,2R/M }.

Optionally, in this embodiment of the present invention, the first uplink transmission power is an uplink transmission power calculated according to configuration information of the uplink transmission power.

For example: the uplink transmission power calculated according to the configuration information of the uplink transmission power may be calculated according to a manner defined in a protocol, so as to obtain the first uplink transmission power. For example: terminal uplink for PUSCH based on base stationThe configuration information of the transmission power calculates the uplink transmission power. Preferably, the calculated uplink transmission power is the uplink transmission power without considering the influence of the precoding matrix of the uplink signal (for example, in section 7.1.1 of 3GPP protocol TS38.213, a calculation method of PUSCH uplink transmission power is defined, and with the calculation method, the terminal calculates the transmission power of the PUSCH as P _PUSCH,b,f,c (i,j,q _d L))) according to the present invention, the uplink transmission power is marked as P.

Optionally, the first antenna port number includes:

the number of SRS antenna ports contained in the first sounding reference signal SRS resource; or

And the terminal supports the maximum number of SRS antenna ports contained in the SRS resource based on the uplink transmission of the codebook.

In this embodiment, the first number of antenna ports may be the number of SRS antenna ports included in the first SRS resource, or the first number of antenna ports may be the maximum number of SRS antenna ports included in one SRS resource supported by the terminal, or the first number of antenna ports may be the maximum number of SRS antenna ports included in SRS resources supported by the terminal and transmitted in uplink based on a codebook (for example, in an NR system, SRS resources transmitted in uplink based on a codebook are SRS resources in an SRS resource set whose usage is "codebook").

Therefore, the service performance of the terminal transmitting power can be further improved.

Optionally, the first SRS resource includes:

For example: the first SRS resource may be an SRS resource configured by the base station for the terminal and used for codebook-based uplink transmission. For example, in the NR system, any SRS resource in the SRS resource set whose usage is "codebook" in the RRC signaling SRS-resources set configured for the base station for the terminal. In this way, all SRS resources configured by the base station for the terminal for codebook-based uplink transmission have the same number of antenna ports.

Another example is: the first SRS resource may be an SRS resource configured by the base station for the terminal and having the largest number of antenna ports configured in the SRS resources for codebook-based uplink transmission. For example, in the NR system, the SRS resource with the largest number of antenna ports in the SRS resource set whose usage is "codebook" in the RRC signaling SRS-resources set for the base station to the terminal. In this case, the number of antenna ports of the SRS resources in the SRS resource set with one usage of "codebook" may be different, for example, the number of antenna ports of one SRS resource is 2, the number of antenna ports of another SRS resource is 4, and at this time, the first SRS resource is the SRS resource with the number of antenna ports of 4.

Another example is: the first SRS resource may be an SRS resource corresponding to the PUSCH transmission indicated by the base station for the terminal. The SRS resource may be indicated by the SRI, and may be indicated by DCI, MAC-CE, or RRC. For example, for the codebook-based uplink transmission based on DCI scheduling, the SRS resource is an SRS resource that is indicated to the UE by the base station through SRI in DCI format 0_1. For another example, for the PUSCH transmission scheme of configured grant Type 1, the first SRS Resource is an SRS Resource indicated by the base station through RRC signaling SRS-Resource Indicator.

As an optional implementation manner, the determining, by the terminal, the transmission power of the uplink signal according to the coherent transmission capability of the terminal may include:

and when the terminal supports full power transmission, the terminal determines the transmission power of the uplink signal according to the coherent transmission capability of the terminal.

The terminal may support full power transmission, or the terminal may support full power transmission may support a full power transmission characteristic, and the characteristic is in an active state.

Optionally, the terminal may send with full power may refer to that the terminal reports an uplink sending power capability signaling, and the signaling indicates that the terminal supports the terminal that at least part of the codewords may reach full power sending. Optionally, the characteristic is a transmission power capability indication signaling for a certain type of uplink signal, when the terminal considers that full power transmission is possible under this type of uplink signal. Such an uplink signal is, for example, a codebook-based PUSCH. Optionally, only the terminals with non-coherent transmission capability and partially coherent transmission capability need to report the signaling, and for the terminal with full coherent transmission capability, the base station considers that the terminal is a terminal supporting full power transmission. Of course, the name of the signaling reported by the UE may not be related to the power, but is named as a parameter, and the parameter indicates the uplink transmission power control rule supported by the terminal, and the uplink transmission power control rule corresponds to the power control rule of the full power transmission UE mentioned in the present invention. For example, there are at least two uplink transmission power control rules in the system, wherein there is one set for UEs not supporting full power transmission and one set for UEs supporting full power transmission. The signaling of the uplink transmission power capability reported by the UE corresponds to the rule of the UE supporting full power transmission. The parameter reported by the UE is UL power Rule, and when the value is R15, the UE which indicates the non-coherent transmission capability and the partial coherent transmission capability is not a terminal which transmits at full power; when it takes the value of R16, the UE indicating the non-coherent transmission capability and the partially coherent transmission capability is a full power transmitting UE. R15 and R16 are only examples of some nomenclature herein.

Alternatively, the base station may turn off the full power transmission characteristic of the terminal by indicating a signaling to the terminal, when the terminal is no longer a full power transmitting terminal, and the terminal adopts the power control rule when the terminal is not a full power transmitting terminal.

Optionally, the base station may also turn off the full power transmission characteristic of the UE by indicating a signaling to the terminal, and at this time, the terminal considers that the full power transmission characteristic is not activated, and the terminal adopts the power control rule of the uplink signal when the terminal is not transmitting the full power. For the terminal of the NR system, this power control rule for the non-full power transmission is a transmission power control rule for the uplink signal of R15.

Referring to fig. 3, fig. 3 is a flowchart of a channel quality determining method according to an embodiment of the present invention, as shown in fig. 3, including the following steps:

301. the network side equipment determines reference power information corresponding to first information according to the coherent transmission capability of the terminal, wherein the first information is information used for determining uplink scheduling information of an uplink signal;

302. and the network side equipment determines the channel quality corresponding to the first information according to the reference power information.

Wherein, the coherent transmission capability of the terminal may refer to the embodiment shown in fig. 2.

The first information may be any information used by the network side device to determine the uplink scheduling information of the uplink signal, for example: the first information may be a candidate precoding matrix, that is, a precoding matrix before an undetermined precoding matrix actually used for uplink transmission of the uplink signal (a codeword in a codebook for uplink transmission of the uplink signal), and of course, the first information may also be other information, for example: other candidate uplink scheduling information, etc., which are not limited in this embodiment of the present invention. The uplink scheduling information may be actual scheduling information of uplink transmission, for example: the determined precoding matrix actually used for uplink transmission of the uplink signal, or the number of transmission streams or other scheduling information may be included.

In addition, in the embodiment of the present invention, the uplink scheduling information of the PUSCH may be determined according to the channel quality determined in step 302, for example: actual precoding matrix, scheduling, etc.

In addition, in this embodiment of the present invention, reference power information corresponding to a plurality of pieces of first information may be determined, for example: the base station determines and calculates reference power information corresponding to the uplink signal under each precoding matrix (or code word) according to the coherent transmission capability of the terminal. The base station can calculate the channel quality of a plurality of pieces of first information according to the reference power information, so that the first information with the best channel quality or meeting preset conditions is finally selected as uplink scheduling information from the pieces of first information.

In this embodiment of the present invention, the reference power information may be power or a coefficient, where the coefficient is a power coefficient, for example: ratio to the basic transmit power.

It should be noted that the reference power information is not limited to actual power information, and therefore, the reference power information may be defined as assumed reference power information or a transmission power assumption corresponding to an uplink signal.

As an alternative implementation, step 301 may include:

for a terminal supporting full power transmission, network side equipment determines reference power information corresponding to first information according to the coherent transmission capability of the terminal.

The terminal supporting full power transmission refers to a terminal reporting an uplink transmission power capability signaling, and the signaling indicates that the terminal supports at least part of codewords which can achieve full power transmission. Optionally, only the terminals with non-coherent transmission capability and partial coherent transmission capability need to report the signaling, and for the terminal with full coherent transmission capability, the base station considers the terminal as a terminal supporting full power transmission. Of course, the name of the signaling reported by the terminal may not be related to the power, but is named as a parameter, and the parameter indicates the uplink transmission power control rule supported by the terminal, and the uplink transmission power control rule corresponds to the power control rule of the full power transmission terminal mentioned in the present invention. For example, there are at least two uplink transmission power control rules in the system, wherein the uplink transmission power control rules are set for terminals that do not support full power transmission, and the uplink transmission power control rules are set for terminals that support full power transmission. The signaling of the uplink transmission power capability reported by the terminal corresponds to the rule of the terminal supporting full power transmission. The parameter reported by the terminal is ULpowerRule, and when the value is R15, the terminal which indicates the non-coherent transmission capability and the partially coherent transmission capability is not a terminal which transmits at full power; when it takes the value of R16, the terminal representing the non-coherent transmission capability and the partially coherent transmission capability is a terminal of full power transmission.

Alternatively, the base station may turn off the full power transmission characteristic of the terminal by indicating a signaling to the terminal, and the base station considers that the terminal is not the terminal transmitting at full power, and the terminal adopts the power control rule when the terminal is not transmitting at full power.

Optionally, the full power transmission characteristic means that any one antenna of the terminal can transmit at full power.

Optionally, the full power transmission characteristic refers to a characteristic that the base station can transmit at full power when the precoding matrix of the uplink signal is a precoding matrix of rank-X corresponding to the maximum coherent transmission capability of the terminal. Where X > = Y, Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be deduced according to the uplink transmission power control rule defined by the protocol. Rank-X means that the number of transmission streams corresponding to the precoding matrix is X. For PUSCH based on codebook, X corresponds to the precoding matrix corresponding to the PUSCH and the number of layers (or layer number, or stream number) in the transmission stream number indication information indicated by the base station for the terminal.

Optionally, the full power transmission characteristic means that when the number of antenna ports of the precoding matrix is equal to the maximum number of antenna ports of the uplink signal transmission supported by the terminal, and the precoding matrix is a rank-X precoding matrix corresponding to the maximum coherent transmission capability of the terminal, the terminal can achieve full power transmission. Where X > = Y, Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be deduced according to the uplink transmission power control rule defined by the protocol. Rank-X means that the number of transmission streams corresponding to the precoding matrix is X. For a PUSCH based on a codebook, X corresponds to a precoding matrix corresponding to the PUSCH and the number of layers (layer number) in the transmission stream number indication information indicated by the base station for the terminal.

Optionally, the maximum number of antenna ports of the codebook-based PUSCH transmission supported by the terminal is the maximum number of SRS resources included in one SRS resource supported by the terminal.

Optionally, the maximum number of antenna ports of the codebook-based PUSCH transmission supported by the terminal is the maximum number of SRS ports included in the SRS resource for the codebook-based PUSCH transmission supported by the terminal.

In addition, in this embodiment, for the uplink signal, reference may be made to the relevant description of the embodiment shown in fig. 2, which is not described herein again.

As an optional implementation, the coherent transmission capability includes:

a coherent transmission capability supported by the terminal; or alternatively

The terminal reports the coherent transmission capability to the network side equipment; or alternatively

Optionally, the first indication signaling includes:

codebook subset restriction signaling of the uplink signal;

wherein, if the codebook subset of the codebook subset restriction signaling is configured to be non-coherent, the maximum coherent transmission capability of the terminal is non-coherent transmission capability; or

Optionally, the method further includes:

It should be noted that, the first indication signaling in this embodiment may refer to the corresponding description of the embodiment shown in fig. 2, and is not described herein again.

As an optional implementation manner, the determining, by the network side device, the reference power information corresponding to the first information according to the coherent transmission capability of the terminal includes:

In this embodiment, the implementation manner of determining the transmission power of the uplink signal may be referred to the embodiment shown in fig. 2, and the same beneficial effects may be achieved.

In one implementation manner, the determining, by the network side device, reference power information corresponding to first information according to a predefined power information control rule and using coherent transmission capability of the terminal includes:

In a second case, determining the power of the reference power information corresponding to the first information as the power obtained by scaling the second uplink transmission power according to a third scaling factor, or determining that the coefficient of the reference power information corresponding to the first information is the third scaling factor, where the second case is any case where the first information is a codeword other than the codeword corresponding to the first information in the first case.

Taking the first information as a precoding matrix (a candidate precoding matrix before the actual precoding matrix for uplink transmission is not determined), in this embodiment, when the precoding matrix is a precoding matrix corresponding to rank-X with the maximum coherent transmission capability of the terminal, the base station may assume that the transmission power corresponding to the precoding matrix is P, where X > = Y, and Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be derived according to the uplink transmission power control rule defined by the protocol. Preferably, Y =1.Rank-X means that the number of transmission streams corresponding to the precoding matrix is X. For a codebook-based P-terminal CH, X corresponds to the precoding matrix and the number of layers (layer number) in the transmission stream number indication information corresponding to the P-terminal CH indicated by the base station for the terminal.

In this embodiment, the predefined uplink signal transmission power control rule may further include: when the precoding matrix is other precoding matrices (not the precoding matrix of rank-X corresponding to the maximum coherent transmission capability of the terminal E), the transmit power corresponding to the precoding matrix is the power obtained by scaling P according to the first scaling factor.

In another implementation manner, the determining, by the network device according to a predefined power information control rule and using the coherence transmission capability of the terminal, reference power information corresponding to the first information includes:

Also taking the first information as a precoding matrix (candidate precoding matrix before the actual precoding matrix for uplink transmission is not determined), in this embodiment, it can be implemented that when the number of antenna ports of the precoding matrix is equal to the maximum number of antenna ports for uplink signal transmission supported by the terminal, and the precoding matrix is a precoding matrix of rank-X corresponding to the maximum coherent transmission capability of the terminal, the base station assumes that the transmission power of the precoding matrix is P, where X > = Y, and Y is a predefined positive integer. The predefined mode of Y can be specified by the protocol or can be derived according to the uplink transmission power control rule defined by the protocol. Preferably, Y =1.Rank-X means that the number of transmission streams corresponding to the precoding matrix is X. For a PUSCH based on a codebook, X corresponds to the number of layers (layer number) in the precoding matrix and transmission stream number indication information corresponding to the PUSCH that the base station indicates for the terminal.

In this embodiment, the predefined uplink signal transmission power control rule may further include: when the precoding matrix is other precoding matrices (not a precoding matrix with the number of antenna ports equal to the maximum number of antenna ports for uplink signal transmission supported by the terminal and corresponding to rank-X with the maximum coherent transmission capability of the UE), the transmit power corresponding to the precoding matrix is power obtained by scaling P by a first scaling factor.

Taking the first information as an example of the precoding matrix, the third scaling factor may be: the smaller value between the ratio of the number of activated antenna ports corresponding to the precoding matrix to the number of activated antenna ports when the precoding matrix is a rank-Y precoding matrix corresponding to the maximum coherent transmission capability of the terminal and 1. The number of activated antenna ports corresponding to the precoding matrix may refer to the number of antenna ports having non-zero elements in the precoding matrix.

Example three: the uplink signal is a PUSCH based on a codebook, and Y =1.

The third scaling factor is shown in table 4 below, wherein the manner in which the terminal does not scale the transmission power P can be regarded as corresponding to the manner in which the first scaling factor is 1

Table 4:

example four: the uplink signal is a PUSCH based on a codebook, and Y =1.

The third scaling factor is as shown in table 5 below, wherein the manner in which the terminal will not scale the transmission power P may be considered as corresponding to the manner in which the first scaling factor is 1.

It should be noted that, in the implementation of the present invention, the codewords in the uplink codebook may be divided into three types, which are: fully coherent, partially coherent, and non-coherent transmitted codewords. Wherein, any column in the code word of the partial coherent transmission only corresponds to the non-zero elements belonging to the same coherent transmission antenna group (for example, in the 3GPP NR system, the 1st and 3 rd antennas are a coherent transmission antenna group, and the 2 nd and 4 th antennas are another coherent transmission antenna group); any column in the non-coherent transmission code word only has non-zero elements corresponding to one antenna; at least one column of all elements in the full coherent transmission codeword is non-zero.
