Title:
NETWORK INFORMATION EXCHANGE FOR CROSS-LINK INTERFERENCE MANAGEMENT WITH INTELLIGENT REFLECTING SURFACES
Document Type and Number:
WIPO Patent Application WO/2022/236767
Kind Code:
A1
Abstract:
Example aspects include a method, apparatus, and computer-readable medium of managing cross-link interference (CLI) by a first network node of a wireless communication network, comprising generating a reflection coefficient measurement configuration for an intelligent reflecting surface (IRS) controlled by the first network node to mitigate the CLI caused by a first user equipment (UE) controlled by the first network node to a second UE controlled by a second network node. The aspects further include transmitting network information comprising the reflection coefficient measurement configuration. Additionally, the aspects further include receiving, in response to transmitting the network information, CLI measurement information associated with the second UE. Additionally, the aspects further include identifying a particular reflection coefficient from a set of different reflection coefficients associated with the reflection coefficient measurement configuration. Additionally, the aspects further include configuring the IRS with the particular reflection coefficient.
