Abstract
Apparatuses and methods for channel access requests in downlink transmissions. A method of operating a user equipment (UE) includes receiving, from a base station (BS), a downlink control information (DCI) format in physical downlink control channels (PDCCHs), determining a number of beam directions to sense, and determining a number of channel access request (CARQs) in a burst. The method further includes determining, based on at least one field in the DCI format, a set of CARQs according to the number of CARQs in the burst and a set of beam directions according to the number of beam directions to sense.
Claims19
A base station (BS) in a wireless communication system including a carrier operating with shared spectrum channel access, the BS comprising:
- a processor configured to:
- determine a number of beam directions to sense;
- determine a number of channel access requests (CARQs) in a burst;
- and
- determine at least one field in a downlink control information (DCI) format, wherein the at least one field indicates:
- a set of CARQs according to the number of CARQs in the burst;
- and
- a set of beam directions according to the number of beam directions to sense;
- and
- a transceiver operably connected to the processor, the transceiver configured to transmit, to a user equipment (UE), the DCI format including the at least one field in physical downlink control channels (PDCCHs).
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver configured to receive, from a base station (BS), a downlink control information (DCI) format in physical downlink control channels (PDCCHs);
- and
