Channel state information feedback for full duplex cellular communications

摘要

A method is performed at a user device, UE (12), for supporting a transmission mode configuration with respect to a communication channel between the UE (12) and an network node (14) of a radio network. The method comprises determining an impact of self-interference at a receiver of the UE (12) due to an uplink transmission to the network node (14) in case of full duplex communication, generating a channel state information comprising an information of said impact of self-interference, and transmitting the channel state information to the network node (14) to support said node in taking a decision between half duplex and full duplex communication configuration for the communication channel. A corresponding method is performed at a network node (14). Embodiments herein further include a UE (12), a network node (14) and computer programs thereto.
