Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a remote user equipment (UE) may receive a measurement reference channel configuration from a source relay. The UE may transmit a reference channel based at least in part on the measurement reference channel configuration. The UE may receive, from the source relay, a command for the remote UE to switch from the source relay to a target relay based at least in part on a measurement of the reference channel transmitted from the remote UE. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a remote user equipment (UE), comprising:
- receiving a measurement reference channel configuration from a source relay, the measurement reference channel configuration including a set of parameters configuring the remote UE to transmit a reference channel to a network entity or to the source relay and at least one candidate relay;
- transmitting, responsive to a channel condition between the remote UE and the source relay satisfying a threshold, the reference channel via a broadcast based at least in part on the measurement reference channel configuration, wherein the reference channel includes a remote UE identifier;
- and
- receiving, from the source relay, a relay switch command that indicates the at least one candidate relay as a target relay, the relay switch command being for the remote UE to switch from the source relay to the target relay,
- wherein receiving the relay switch command for the remote UE to switch is based at least in part on a measurement of the reference channel transmitted from the remote UE.
A method of wireless communication performed by a relay, comprising:
- receiving, from a remote user equipment (UE), a reference channel via a broadcast based at least in part on a channel condition between the remote UE and the relay satisfying a threshold, wherein the reference channel includes a remote UE identifier;
- performing a measurement of the reference channel received from the remote UE;
- and
- transmitting, to the remote UE, a relay switch command that indicates a target relay, the relay switch command being for the remote UE to switch to the target relay,
- wherein transmitting the relay switch command for the remote UE to switch is based at least in part on the measurement of the reference channel received from the remote UE.
A remote user equipment (UE) for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive a measurement reference channel configuration from a source relay, the measurement reference channel configuration including a set of parameters configuring the remote UE to transmit a reference channel to a network entity or to the source relay and at least one candidate relay;
- transmit, responsive to a channel condition between the remote UE and the source relay satisfying a threshold, the reference channel via a broadcast based at least in part on the measurement reference channel configuration, wherein the reference channel includes a remote UE identifier;
- and
- receive, from the source relay, a relay switch command that indicates the at least one candidate relay as a target relay, the relay switch command being for the remote UE to switch from the source relay to the target relay,
- wherein receiving the relay switch command for the remote UE to switch is based at least in part on a measurement of the reference channel transmitted from the remote UE.
A relay for wireless communication, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to:
- receive, from a remote user equipment (UE), a reference channel via a broadcast based at least in part on a channel condition between the remote UE and the relay satisfying a threshold, wherein the reference channel includes a remote UE identifier;
- perform a measurement of the reference channel received from the remote UE;
- and
- transmit, to the remote UE, a relay switch command that indicates a target relay, the relay switch command being for the remote UE to switch to the target relay,
- wherein transmitting the relay switch command for the remote UE to switch is based at least in part on the measurement of the reference channel received from the remote UE.
