Problems solved by technology

Although the dynamic TDD technology can dynamically configure the uplink and downlink transmission directions according to the service status of the cell, when adjacent cells transmit information in different directions (uplink or downlink) on the same time-frequency resource, such as figure 1 As shown, cell 1 is in the downlink (DL) and cell 2 is in the uplink (UL). At this time, two types of cross-link interference (Cross-Link Interference, CLI), that is, TRP (Transmission Reception Point, transmission receiving point)-TRP and UE (User Equipment, user terminal)-UE interference

Abstract

Provided are a method for measuring cross-link interference between user terminals, a user terminal, and a transmission reception point. The method comprises: receiving measurement reference signal configuration information sent by a second transmission reception point; sending the measurement reference signal configuration information to all or part of user terminals served by a first transmission reception point; and receiving cross-link interference measurement values reported by all or part of the user terminals served by the first transmission reception point, the cross-link measurement values being obtained by all or part of the user terminals performing cross-link interference measurement according to the received measurement reference signal configuration information.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for measuring cross-link interference between user terminals, a user terminal and a transmission receiving point. Background technique [0002] There are two duplex modes in traditional mobile communication systems, namely FDD (Frequency Division Duplex) and TDD (Time Division Duplex). The FDD system uses different frequency bands to receive and transmit signals at the same time, while the TDD system uses different times to receive and transmit signals on the same frequency band. Compared with TDD, FDD has the advantages of wide uplink coverage and simple interference handling, and does not require strict synchronization of the network. FDD must use paired transceiver frequency bands. When supporting uplink and downlink symmetric services, the uplink and downlink spectrum can be fully utilized. When supporting uplink and downlink asymmetric services, the ...
