5G NEW RADIO WITH SHARING BETWEEN PRIORITY ACCESS LICENSE AND GENERAL AUTHORIZED ACCESS COMMUNICATIONS

Abstract:

A method of wireless communication may include determining a communication operation between a base station and one or more served UEs. The method may further include monitoring for radio frequency (RF) energy on a communication channel at a beginning of a listen before talk (LBT) window of a current frame in a shared spectrum shared between at least one or more opportunistic general authorized users. The method may further include transmitting an LBT trigger signal in response to detection of no RF energy above a minimum energy threshold at the beginning of the LBT window. The method may further include receiving an LBT trigger response signal from the one or more served UEs. The method may also include communicating, by the base station, with the one or more UEs during a channel occupancy time (COT) of the current frame after the LBT window.
