When, so that it may it determines to transmit corresponding PUSCH target power based on authorization (grant) according to the first corresponding relationship and path is damaged
Compensation factor is consumed, due to also provided the corresponding PUSCH target power of the first parameter of multiple groups and path damage in the second corresponding relationship
Consume compensation factor, it is possible to corresponding first parameter of the PUSCH of current transmission period is determined, in this way, can determine to state
In formula (1)And PO_PUSCH,f,c(j)。
In a kind of possible embodiment, terminal is determined and is used according at least to the service type of the PUSCH of current transmission period
In the second parameter of path loss compensating parameter, comprising: terminal is according to the service type of the PUSCH of current transmission period, from down going wave
The second parameter for path loss measurement is determined in the reference signal of beam.
Since each downlink wave beam corresponds to the reference signal of itself, and the target of downlink wave beam and uplink PUSCH wave beam is sent out
The mapping relations of power are sent, and this mapping relations can be configured by high-level signaling, in this way, can determine and uplink PUSCH
The target of wave beam sends the downlink wave beam that power matches, and then the associated downlink wave beam medium wave beam tube is managed reference signal

Third parameter.
In second situation, wave beam manage reference signal and two close-loop power control rings one of them be associated
Mapping relations configured by high-level signaling, and then terminal determine downlink wave beam wave beam management reference signal after, just
It can determine the number of associated closed-loop control ring.
In a kind of possible implementation, terminal shares channel PUSCH according at least to the ascending physical signal of current transmission period
Service type, before the PUSCH power contorl parameters for determining current transmission period, further includes: terminal determines where terminal
Serving cell is non-scheduled serving cell.That is, if the serving cell where terminal is non-
There is no sounding reference signal resources to indicate SRI in scheduled serving cell and downlink control message, then according at least to
Terminal shares the service type of channel PUSCH according at least to the ascending physical signal of current transmission period, determines the current transmission week
The PUSCH power contorl parameters of phase.
In alternatively possible implementation, terminal is if it is determined that there is no detection reference signals to provide in downlink control message
When serving cell when source indicates SRI and where terminal is non-scheduled serving cell, according to the default value of pre-configuration,
Determine the transmission power of PUSCH；The default value of pre-configuration be used for confirm the first parameter target power and path loss compensate because
The default value and third parameter of sub default value, the second parameter.
Optionally, the default value of pre-configuration is matched by higher level parameters SRI-PUSCH Power Control-Mapping
It sets.
It can be seen from the above: terminal receives the downlink control message that base station is sent；If terminal determines downlink control
There is no when sounding reference signal resource instruction SRI in message, that is to say, that there is no instruction PUSCH in downlink control message
The relevant information of power contorl parameters, then terminal shares the clothes of channel PUSCH according at least to the ascending physical signal of current transmission period
Service type determines the PUSCH power contorl parameters of current transmission period；PUSCH power contorl parameters are for terminal according to default
Algorithm determines the transmission power of PUSCH.In this way, may be implemented that sounding reference signal resource instruction is not present in downlink control message
The PUSCH power contorl parameters of current transmission period are determined in the case where SRI, and then can determine the transmission function of PUSCH
