Title:
SIDELINK CONFLICT DETERMINATION FOR HIDDEN NODES
Document Type and Number:
WIPO Patent Application WO/2024/065586
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications at a first user equipment (UE) may be described. A user equipment (UE) may receive, from second and third UEs, first and second sidelink reservation messages that reserve at least first and second sidelink resources and indicate first and second starting transmission points for transmission of first and second messages. The UE may determine that the first and second sidelink resources overlap in time and frequency. The UE may transmit a conflict indication message to the second UE or the third UE based on a transmission conflict, the transmission conflict being identified based on the first and second starting transmission points and whether the second UE and the third UE may be hidden nodes to one another.
