Abstract

The present application provides a method and device for controlling uplink power. The method includes: a terminal device receives uplink power control information sent by a network device; the terminal device determines the target corresponding to the target uplink multiple access mode according to the uplink power control information; A power control parameter: the terminal device determines, according to the target power control parameter, a target transmission power when the target uplink multiple access mode is used to transmit a target uplink signal. The method and device for controlling uplink power provided by the present application can flexibly adjust uplink transmission power to meet the requirements of different uplink multiple access modes, and is applicable to communication systems supporting multiple uplink multiple access modes.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a method and device for controlling uplink power. Background technique [0002] In a Long Term Evolution (LTE for short) system, the uplink transmission power is determined by the terminal device according to the power control parameters configured on the network side and the downlink path loss measured by the terminal device. Various uplink multiple access modes will be introduced into the uplink transmission of the future wireless communication system, and the methods for performing uplink power control in the related art cannot meet the requirements of different uplink multiple access modes. Therefore, it is necessary to provide a method for controlling uplink power in a communication system supporting multiple uplink multiple access modes. Contents of the invention [0003] The present application provides a method and device for controlling u...
