5G new radio with sharing between priority access license and general authorized access communications

An apparatus configured for wireless communication, the apparatus comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor,
• wherein the at least one processor is configured:
• to determine, by a base station, a communication operation between the base station and one or more served UEs;
• to monitor, by the base station, 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;
• to transmit, by the base station, an LBT trigger signal on the communication channel in response to detection, via execution of the at least one processor to monitor, of no RF energy on the communication channel above a minimum energy threshold at the beginning of the LBT window;
• to receive, by the base station, an LBT trigger response signal on the communication channel from the one or more served UEs within the LBT window, wherein the base station detects, via execution of the at least one processor to monitor, the RF energy from one or the one or more served UEs or the base station on the communication channel remains above the minimum energy threshold for a remainder of the LBT window;
• to communicate, by the base station, with the one or more UEs on the communication channel during a channel occupancy time (COT) of the current frame after the LBT window;
• to receive, by the base station, new data for transmission, wherein the new data is received after a start of the COT of the current frame;
• and
• to transmit, by the base station in response to a failure to detect, via execution of the at least one processor to monitor, the RF energy on the communication channel above the minimum energy threshold in the COT, at least a portion of the new data on the communication channel in a remaining portion of the COT when the LBT window is synchronized with one or more competing LBT windows of one or more neighboring users.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for determining, by a base station, a communication operation between the base station and one or more served UEs;

• code for receiving, by the base station, an LBT trigger response signal on the communication channel from the one or more served UEs within the LBT window, wherein the base station detects, via execution of the code for monitoring, the RF energy from one of the one or more served UEs or the base station on the communication channel remains above the minimum energy threshold for a remainder of the LBT window;
• code for communicating, by the base station, with the one or more UEs on the communication channel during a channel occupancy time (COT) of the current frame after the LBT window;
• code for receiving, by the base station, new data for transmission, wherein the new data is received after a start of the COT of the current frame;
• and
• code for transmitting, by the base station in response to a failure to detect, via execution of the code for monitoring, the RF energy on the communication channel above the minimum energy threshold in the COT, at least a portion of the new data on the communication channel in a remaining portion of the COT when the LBT window is synchronized with one or more competing LBT windows of one or more neighboring users.
