Claim of US Patent No. 10,368,316

1. A base station to serve at least two user equipments (UEs) comprising a first UE and a second UE, and the base station comprising:a processor, configured to obtain power parameters of the first UE and an adjustment parameter ?1,ue1 for a first transmit power, wherein the power parameters of the first UE comprise a UE-specific parameter PA,ue1 of the first UE, a cell-specific parameter PB,ue1 of the first UE, and a reference signal transmit power of the first UE, and the first transmit power is a transmit power of downlink data for the first UE; and
a transmitter, configured to send the power parameters of the first UE and the adjustment parameter ?1,ue1 for the first transmit power to the first UE; wherein
the processor is further configured to:
determine the first transmit power according to the power parameters of the first UE and the adjustment parameter ?1,ue1 for the first transmit power, and
determine ?ue1 according to PA,ue1, PB,ue1, and the adjustment parameter ?1,ue1 for the first transmit power, and determine the first transmit power according to ?ue1 and the reference signal transmit power of the first UE, wherein ?ue1 indicates a ratio of energy per resource element (EPRE) of a physical downlink shared channel (PDSCH) of the first UE to EPRE of a cell-specific reference signal of the first UE, ?ue1 comprises ?A,ue1 and ?B,ue1, and ?A,ue1 and ?B,ue1 correspond to different orthogonal frequency division multiplexing (OFDM) symbol indexes of the first UE; and
the transmitter is further configured to send the downlink data for the first UE at the first transmit power.
