The UE then determines whether to receive the updated SI message based on the one or more thresholds.

The network controlled repeater operations include receipt of a scheduling message from a serving base station that identifies an amplify and forward (AF) window and an offset prior to a beginning of the AF window. The relay node performs a listen before talk (LBT) procedure on a shared communication channel within the offset. In response to the result of the LBT, the relay node either refrains from AF operations within the AF window in response to failure of the LBT procedure or performs the AF operations on all received signals during the AF window in response to success of the LBT procedure. Other aspects and features are also claimed and described.
