Abstract
In NR networks with dynamic TDD operation, two types of cross-link interference (CLI) arise: UE-to-UE and TRP-to-TRP. UE-to-UE CLI measurement and reporting can assist the network in managing CLI. The problem is that, for a cell to be able to measure the CLI reference signal transmitted by UEs in another neighboring cell, the cell needs to know what CLI-RS transmission resources assigned to the UEs in the neighboring cells. Embodiments of the present disclosure provide systems and methods for the exchange of such information between cells. In some embodiments, for example, a gNB sends a request message to a neighboring gNB and the neighboring gNB sends back a response message that includes TDD DL/UL Configurations of its cells and a list of the resources assigned to its UEs for transmission of UE-to-UE CLI reference signal.
