RECEIVER-SIDE ASSISTANCE INFORMATION USING MULTIPLE UPLINK TRANSMIT OPPORTUNITIES

Abstract:

This disclosure provides systems, methods, and apparatuses for sharing a user equipment (UE)-initiated channel occupancy time (COT) with a base station (BS) by transmitting receiver-side assistance information on an uplink shared channel of an unlicensed radio frequency spectrum band. In some aspects, the UE may perform a clear channel assessment (CCA) prior to an uplink transmit opportunity, and if the CCA is successful, transmit the receiver-side assistance information on the uplink shared channel to share the COT with a BS. Multiple uplink transmit opportunities may be indicated to the UE send the receiver-side assistance information. In some examples, the uplink transmit opportunities may be configured grant occasions for a configured grant or scheduled by downlink control information. By transmitting to the BS, the UE may share the COT with the BS, and the BS may send downlink data to the UE during the COT.
