LISTEN-BEFORE-TALK (LBT) TYPE AND GAP SIGNALING FOR BACK-TO-BACK GRANTS AND MULTI-TRANSMISSION TIME INTERVAL (MULTI-TTI) GRANTS

摘要

Wireless communications systems and methods related to listen-before-talk (LBT) mode and/or transmission gap signaling for back-to-back grants and/or multi-transmission time interval (multi-TTI) grants are provided. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a scheduling grant indicating a gap period within a scheduled period. The first wireless communication device communicates, with the second wireless communication device during the scheduled period, a first communication signal including a silence period corresponding to the gap period. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a first scheduling grant indicating a first scheduled period and a second scheduling grant indicating a second scheduled period spaced apart from the first scheduled period. The first wireless communication device communicates, with the second wireless communication device based on an LBT mode determined based on the first scheduling grant and the second scheduling grant.
