Title:
SIDELINK RESOURCE COLLISION HANDLING AND RESOURCE ALLOCATION THROUGH USER EQUIPMENT COORDINATION
Document Type and Number:
WIPO Patent Application WO/2022/082587
Kind Code:
A1
Abstract:
A user equipment (UE) may detect a collision or interference issues of a second UE and transmit information regarding the detected collision to a base station. The second UE may not able to sense the channel on its own and thus may inadvertently use resources already reserved or in use by other UEs. The information regarding the detected collision may include layer-1 identifiers (L1 IDs) and/or layer-2 identifiers (L2 IDs) corresponding to the UE and/or the second UE as well as additional information corresponding to the resource collision. This information may be usable by the base station in determining that the base station has previously communicated with the second UE and may trigger a resource reselection by the second UE. The UE may receive sidelink communications on one or more reselected sidelink transmission resources from the second UE.
