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

The embodiments of the invention provide a method for measuring cross-link interference between user terminals, the user terminals and transmission receiving points. The method includes the followingsteps: receiving configuration information of a measurement reference signal sent by the user terminal in a service cell of the second transmission receiving point, wherein the second transmission receiving point is an adjacent transmission receiving point of the first transmission receiving point; sending the configuration information of the measurement reference signal to all or part of the userterminals in a service cell of the first transmission receiving point; and receiving cross-link interference measurement values reported by the all or part of the user terminals in the service cell of the first transmission receiving point to realize cross-link interference measurement between the user terminals, wherein the cross-link measurement values are obtained by cross-link interference measurement on time frequency resource positions corresponding to the measurement reference signal by each of the all or part of the user terminals according to the configuration information.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for measuring cross link interference between user terminals, user terminals and transmission receiving points. 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 network synchronization. FDD must use paired transceiver frequency bands to make full use of the uplink and downlink spectrum when supporting symmetric uplink and downlink services. When supporting asymmetric uplink and downlink services, the spectrum utili...
