Title:
U2U RELAY DISCOVERY AND (RE-)SELECTION
Document Type and Number:
WIPO Patent Application WO/2024/033295
Kind Code:
A3
Abstract:
Embodiments provide a UE [e.g., source UE] of a wireless [e.g., radio based] communication system [e.g., 5G/NR communication system], wherein the UE is configured to operate in a sidelink mode of operation [e.g., 5G/NR sidelink mode 1 or mode 2], wherein the UE is configured, for establishing a connection with a target UE or a group of target UEs [e.g., the group of target UEs having a group ID] via a UE-to-UE relay, to transmit [e.g., via the sidelink] a discovery message for discovering one or more candidate relay UEs that are connected or able to connect [e.g., via the sidelink] to the target UE or group of target UEs.
