Title:
SYSTEMS, METHODS, AND DEVICES FOR UNLICENSED SIDELINK PRIORITY TO ACCESS CLASS MAPPING
Document Type and Number:
WIPO Patent Application WO/2024/031729
Kind Code:
A1
Abstract:
The techniques described herein provide solutions for enabling sidelink (SL) unlicensed band or spectrum (SL-U) communications with quality and priority standards. A PC5 quality of service (QoS) identifier (PQI) value may be configured and used to indicate a QoS associated with an SL-U communication (e.g., a channel, data flow, etc.). Similarly, a layer 1 (L1) priority indicator may be configured and used to indicate a priority of an SL-U transmission or SL channel. The PQI and/or L1 priority indicator may be mapped to a channel access priority class (CAPC) value, and the PQI, L1 priority, and/or CAPC values may indicate SL COT sharing, maximum COT, timing gaps for COT sharing, listen-before-talk (LBT) configuration, traffic and channel priorities, and more.
