US 2018/0324707 A1 · UPLINK POWER CONTROL METHOD AND APPARATUS

Abstract

Embodiments of the present disclosure provide an uplink power control method, includes: determining, by a base station, power control information, where the power control information is used to control a power of a UE; sending, by the base station, hybrid automatic repeat request (HARQ) acknowledgment feedback information to X UEs, where the HARQ acknowledgment feedback information carries the power control information of at least one of the X UEs, the X UEs contend for use of a same transmission resource, and X is an integer greater than or equal to 1; receiving, by the UE, acknowledgment feedback information sent by the base station to the X UEs; and parsing the HARQ acknowledgment feedback information; and if it is determined that the HARQ acknowledgment feedback information includes the power control information of the UE, performing power control on the user equipment based on the power control information of the UE.
