Methods and apparatuses for sharing a transmission opportunity

Abstract:

To improve overall throughput and reliability of communications for a user equipment (UE) on a shared radio spectrum, the UE may share an acquired transmission opportunity (TxOP) with multiple transmission receive points (TRPs) or peer UEs. In an aspect of the disclosure, a method, and an apparatus are provided. The apparatus is configured to trigger at least one TRP or at least one peer UE to share an acquired TxOP, and receive downlink/uplink transmissions from the at least one TRP or peer UE during the TxOP based in part on a listen before talk (LBT) indication and a TxOP sharing mode. The apparatus is also configured to obtain the TxOP via an LBT procedure and to adjust a contention window (CW) of the LBT procedure based on a success-failure ratio the downlink/uplink transmissions from the at least one TRP or peer UE.
