US 12,757,100 B2 · Full duplex relay procedures

Abstract

Methods, systems, and devices for wireless communications are described. A relay user equipment (UE) may transmit, to a network entity, a relay report message including information supporting full duplex relaying of reverse link signaling from the remote UE. Such a relay report message may include information that facilitates relaying of the reverse link communications while reducing or mitigating cross-link interference (CLI), self-interference (SI), or both, in a full duplex (FD) mode. For example, the relay report message may include information triggering beam sweeping, beam selection, resource selection, etc., for the relaying of the reverse link communications. In some examples, a network entity may configure sidelink UEs with an FD sidelink slot format that supports sidelink transmissions in the final symbol of a sidelink slot (e.g., instead of relying on one or more gap symbols).

Dependent claims

An apparatus for wireless communications, comprising:

memory;
a transceiver;
and
at least one processor of a first user equipment (UE), the at least one processor coupled with the memory and the transceiver and configured to cause the apparatus to:
transmit, via the transceiver and from the first UE to a network entity, a relay report associated with operation of the first UE in a full duplex mode to relay one or more reverse link messages from a second UE to the network entity, the one or more reverse link messages for receipt by the first UE via sidelink signaling from the second UE and transmission by the first UE via uplink signaling to the network entity;
receive, via the transceiver and while operating in the full duplex mode, a reverse link message for the network entity via the sidelink signaling from the second UE;
and
transmit, via the transceiver and in accordance with the full duplex mode and the relay report, the reverse link message to the network entity via the uplink signaling while continuing to receive the sidelink signaling from the second UE.

transmit an uplink grant to the first UE based at least in part on receiving the relay report, the uplink grant indicating uplink resources for the uplink signaling, the uplink resources at least partially overlapping in time with one or more sidelink resources for the sidelink signaling;
and
receive, from the first UE via one or more of the uplink resources associated with the uplink grant, the uplink signaling comprising a reverse link message from the second UE for the network entity.
