UPLINK POWER CONTROL METHOD AND APPARATUS

Title:

UPLINK POWER CONTROL METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2018/059419

Kind Code:

A1

Abstract:

Provided are an uplink power control method and apparatus. The method comprises: a network side device sending a plurality of pieces of RACH configuration information to a UE, and indicating, via a RACH scheduling message, identification information about RACH configuration information used by the UE; and according to the RACH configuration information corresponding to the identification information, the UE calculating a RACH transmitting power, and according to the RACH transmitting power, sending a random access preamble to the network side device. Each piece of RACH configuration information corresponds to a receiving beam of a network side device or a transmitting beam of a UE, so as to enable the network side device to perform dynamic adjustment on a RACH transmitting power according to forming gain changes in different receiving beams or transmitting beams, thereby being able to precisely control the RACH transmitting power and improve the access success rate of an uplink RACH.
