Abstract
Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment (UE) in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on sidelink that includes multiple quality of service (QoS) flows for a transmission. The UE may receive an indication from a base station (BS) regarding what CAPC to use, or it may itself determine the CAPC based on a rule. The UE may map the plurality of QoS flows to the DRB and transmit the QoS flows using the DRB and the selected CAPC.
Claims30
A method of wireless communication comprising:
- mapping, by a first user equipment (UE), a first plurality of quality of service flows (QoS flows) to a first data radio bearer (DRB) between the first UE and a second UE;
- determining, by the first UE, a channel access priority class (CAPC) for the first DRB for transmitting a first data packet based on a rule applied to the first plurality of QoS flows mapped to the first DRB;
- and
- transmitting, by the first UE to the second UE, the first data packet with the determined CAPC.
A user equipment (UE) comprising:
- a processor configured to:
- map a first plurality of quality of service flows (QoS flows) to a first data radio bearer (DRB) between the UE and a second UE;
- determine a channel access priority class (CAPC) for the first DRB for transmitting a first data packet based on a rule applied to the first plurality of QoS flows mapped to the first DRB;
- and
- a transceiver configured to:
- transmit to the second UE the first data packet with the determined CAPC.
