Abstract
Wireless communications systems and methods related to COT aware autonomous sidelink sensing are provided. A first user equipment (UE) selects at least a first resource from available resources in a sidelink resource pool within a shared radio frequency band. The selecting the first resource may be based on a channel-access gap preceding each resource of the available resources. The first UE further transmits, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.
Claims30
A method of wireless communication performed by a first user equipment (UE), the method comprising:
- sensing a plurality of resources in a sidelink resource pool within a shared radio frequency band, wherein the sensing comprises decoding Sidelink Control Information (SCI);
- identifying a plurality of candidate resources based on the decoded SCI;
- determining a duration of a channel-access gap preceding each of the plurality of candidate resources;
- selecting at least a first resource from the plurality of candidate resources based on the duration of the channel-access gap preceding each of the plurality of candidate resources;
- and
- transmitting, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.
A first user equipment (UE), comprising:
- a processor configured to:
- sense a plurality of resources in a sidelink resource pool within a shared radio frequency band, wherein the sensing comprises decoding Sidelink Control Information (SCI);
- identify a plurality of candidate resources based on the decoded SCI;
- determine a duration of a channel-access gap preceding each of the plurality of candidate resources;
- and
- select at least a first resource from the plurality of candidate resources based on the duration of the channel-access gap preceding each of the plurality of candidate resources;
- and
- a transceiver coupled to the processor, the transceiver configured to transmit, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.
A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- code for causing a first user equipment (UE) to sense a plurality of resources in a sidelink resource pool within a shared radio frequency band, wherein the sensing comprises decoding Sidelink Control Information (SCI);
- code for causing the first UE to identify a plurality of candidate resources based on the decoded SCI;
- code for causing the first UE to determine a duration of a channel-access gap preceding each of the plurality of candidate resources
- code for causing the first UE to select at least a first resource from the plurality of candidate resources based on the duration of the channel-access gap preceding each of the plurality of candidate resources;
- and
- code for causing the first UE to transmit, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.
A first user equipment (UE), comprising:
- means for sensing a plurality of resources in a sidelink resource pool within a shared radio frequency band, wherein the sensing comprises decoding Sidelink Control Information (SCI);
- means for identifying a plurality of candidate resources based on the decoded SCI;
- means for determining a duration of a channel-access gap preceding each of the plurality of candidate resources
- means for selecting at least a first resource from the plurality of candidate resources based on the channel-access gap preceding each of the plurality of candidate resources;
- and
- means for transmitting, to a second UE using the selected first resource, one or more data blocks for a sidelink transmission.
