The B-RSRP of PL=reference wave beams signal power-higher filtering,

Wherein reference wave beam signal power (referenceBeamSignalPower) can be the value provided by higher (for example, layer more higher than physical layer), B-RSRP can be the measurements obtained from the BRS signals for link by UE, may be used also The B-RSRP of higher filtering is obtained to be filtered by the parameter from higher.

UE can also receive the uplink transmitted for UL from UE by the DL control channels in service link and permit.On Line link license can also include the associated power control identifier of the power contorl parameters for identifying UL transmission.

UE is also based on path loss values and associated power control identifier to determine the transmission transmitted for UL Power.In embodiment, transimission power can be based on being received by the signaling from layer more higher than physical layer from TRP or eNB Multiple power contorl parameters.The more details of multiple power contorl parameters can be presented in the further part of the disclosure.

In the case of multiple component carriers or multi-beam transmission, UE can scale the transimission power determined by the above process, So that the overall transmission power of multiple multi-beam transmissions is no more than the uplink transmission power by UE or the eNB permission determined.In reality It applies in example, UE can determine the transimission power for PUSCH, the transimission power for PUCCH, Yi Jiyong sent in subframe In the transimission power of SRS；Obtain transimission power, the transimission power for PUCCH and the transmission work(for SRS for PUSCH The sum of rate.When the sum of the transimission power for PUSCH, the transimission power for PUCCH and transimission power for SRS are more than UE Permission uplink transmission power；UE can be by the transimission power for PUSCH, the transimission power for PUCCH and use A single scale value is scaled in the transimission power of SRS so that for the scaled transimission power of PUSCH, for PUCCH's The uplink transmission of the permission of the sum of scaled transimission power and the scaled transimission power for SRS no more than UE Power.In addition, UE can send signal based on the scaled transimission power for PUSCH, PUCCH or SRS.

UE is also based on the identified transimission power of the chain road indicated by UL grant messages to send signal.The letter Number can by UE received via DL control channels UL license after several subframes (for example, 1-3 subframe) after transmission. From UE UL transmission between several subframes interval can be provided for UE time enough by its wave beam from service DL chains Road is switched to the wave beam for scheduled UL links.In embodiment, signal can be by UE in the subframe with reception UL licenses It is sent in identical subframe.In this case, its wave beam can be switched to from service link and be transmitted for uplink by UE Wave beam.
