Problems solved by technology

It is easy to imagine that when a network device that is performing uplink communication receives an uplink signal, it will be strongly interfered by a downlink signal sent by an adjacent network device that is performing downlink communication
If two network devices use the same operating frequency to transmit uplink signals and downlink signals respectively, the transmission of downlink signals will interfere more strongly with the reception of uplink signals, which will easily lead to failure of network devices to receive uplink signals

Abstract

The present application provides a method and device for uplink power control, which can reduce the impact of interference between network devices on uplink signal transmission, and help improve the probability that network devices receive uplink signals successfully. The method includes: a network device determines an uplink power adjustment parameter value of a terminal device, and the uplink power adjustment parameter value is related to cross-link interference received by the network device; the network device sends the uplink power to the terminal device Information on tuning parameter values.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a method and device for uplink power control. Background technique [0002] In a wireless communication system, according to different duplex modes, duplex can be divided into time division duplex (Time Division Duplex, TDD) and frequency division duplex (Frequency Division Duplex, FDD). In TDD mode, the communication system generally has only one working frequency band. And this working frequency band is only used for uplink communication or downlink communication within a period of time. In FDD mode, the communication system includes a pair of operating frequency bands. One of the working frequency bands is only used for uplink communication, and the other working frequency band is only used for downlink communication. Due to the uneven distribution of terminal devices in the communication network, the number of terminals in the coverage area of ​​different netwo...
