Abstract
A communication method and an apparatus are provided. The method includes: obtaining, by a base station, power parameters of a first user equipment UE and an adjustment parameter δ1,ue1 for a first transmit power; sending, by the base station, the power parameters of the first UE and the adjustment parameter δ1,ue1 for the first transmit power to the first UE; determining, by the base station, the first transmit power according to the power parameters of the first UE and the adjustment parameter δ1,ue1 for the first transmit power; and sending, by the base station, a signal to the first UE at the first transmit power.
Claims17
A base station, wherein the base station serves at least two user equipments (UEs), the at least two UEs comprise a first UE and a second UE, and the base station comprises:
- a processor, configured to obtain power parameters of the first UE and an adjustment parameter δ1,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 δ1,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 δ1,ue1 for the first transmit power;
- and
- the transmitter is further configured to send the downlink data for the first UE at the first transmit power.
A communication method, wherein the method is applied to a communications network comprising at least two user equipments (UEs), the at least two UEs comprise a first UE and a second UE, and the method comprises:
- obtaining, by a base station, power parameters of the first user equipment UE and an adjustment parameter δ1,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;
- sending, by the base station, the power parameters of the first UE and the adjustment parameter δ1,ue1 for the first transmit power to the first UE;
