Abstract

The invention discloses a cross-link interference measurement method, network side equipment, a terminal and a system. The present invention relates to the technical field of wireless communications,in order to solve the problems of unspecified how to trigger CLI measurement and large signaling overhead, and the device of the present invention comprises: a first network side device, used for determining an interference applying terminal located in a local cell and capable of interfering with terminals of other cells, and sending first configuration information to the interference applying terminal; a second network side device used for determining an interfered terminal which is located at the edge of the cell and can be interfered by terminals of other cells, and sending second configuration information to the interfered terminal; an interference applying terminal which is used for receiving the first configuration information and sending a CLI measurement reference signal accordingto the first configuration information; and the disturbed terminal which is used for receiving the second configuration information, receiving the CLI measurement reference signal according to the second configuration information and carrying out measurement. Because measurement is triggered through the configuration information and measurement is only started for part of the terminals, the signaling overhead is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for measuring cross-link interference, a network side device, a terminal and a system. Background technique [0002] In NR (New Radio, new air interface), for cells configured with TDD (Time Division Duplexing, Time Division Duplex) mode, the transmission directions between users served by adjacent cells may be different, resulting in CLI (CrossLink Interference, crossover link interference). Cross-link interference can be divided into two types. The first type is base station-to-base station interference, which can also be referred to as interference from downlink transmission to uplink transmission. The second type is user-user interference, which may also be referred to as interference from uplink transmission to downlink transmission. [0003] When a cell adopts D-TDD (Dynamic Time Division Duplexing, dynamic time division duplexing) configur...
