US 2026/0019936 A1 · RELAY SELECTION ASSOCIATED WITH WTRU-TO-WTRU RELAYS

Abstract

Systems, methods, and instrumentalities are described herein for relay selection associated with WTRU-to-WTRU relays. A wireless transmit/receive unit (WTRU) may be configured to perform relay selection associated with WTRU-to-WTRU relays. The WTRU may (e.g., determine to) perform relay (re)selection, for example, based on active traffic and/or performed measurements (e.g., reference signal received power (RSRP) measurements). The WTRU may perform network assisted relay (re)selection. The WTRU (e.g., in coverage WTRU) may initiate a connection (e.g., RRC connection) or trigger a message (e.g., RRC message), for example, based on WTRU-to-WTRU relaying criteria. The WTRU may report measurements to the network, for example, based on multiple hops.

1-16. (canceled)

A wireless transmit/receive unit (WTRU) comprising:

a processor configured to:
receive configuration information indicating a first threshold, a second threshold, and data transmission gap information;
send a first transmission to a first relay;
determine a reference signal received power (RSRP) associated with the first relay;
determine that the RSRP associated with the first relay is below the first threshold and above the second threshold;
based on the determination that the RSRP associated with the first relay is below the first threshold and above the second threshold:
determine that a data transmission time gap threshold is met, wherein the data transmission time gap threshold is determined based on the data transmission gap information, and
based on the determination that the data transmission gap threshold is met, perform relay reselection to a second relay;
and
send a second transmission to the second relay.
