Title:
TECHNIQUES FOR SIDELINK USER EQUIPMENT COORDINATION
Document Type and Number:
WIPO Patent Application WO/2023/004758
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. To improve sidelink reservation schemes, a first user equipment (UE) may indicate its preferences for sidelink resources to a second UE that may select sidelink resources for sidelink messages based on the indicated preferences. For example, the first UE may monitor a first set of sidelink resources for sidelink control information (SCI) to determine which sidelink resources of a second set of sidelink resources are available. Based on the monitoring, the first UE may generate a bitmap that indicates the first UE's preferences for the sidelink resources of the second set and may transmit a coordination message to the second UE that includes the bitmap. The second UE may receive the coordination message and transmit, to the first UE, one or more sidelink messages using one or more sidelink resources of the second set selected based on the indicated preferences.
