1. An apparatus for wireless communication at a user equipment (UE), comprising:
a memory; and
at least one processor coupled to the memory and configured to:
receive, from a source relay, a candidate relay configuration, the candidate relay configuration including information of candidate relays and a relay measurement configuration comprising a measurement gap configuration indicating that a measurement gap is utilized for reference signals from candidate relays that are not within a bandwidth configured for communication between the UE and the source relay;
measure a reference signal of the source relay and each of the candidate relays based on the candidate relay configuration;
transmit, to the source relay, a measurement report of the reference signal of a subset of candidate relays;
establish a connection with the subset of candidate relays; and
receive, from the source relay, a relay switch command to switch to a target relay from the subset of candidate relays.
 
7. An apparatus for wireless communication at a source relay, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
transmit, to a user equipment (UE), a candidate relay configuration, the candidate relay configuration including information of candidate relays and a relay measurement configuration comprising a measurement gap configuration indicating that a measurement gap is utilized for reference signals from candidate relays that are not within a bandwidth configured for communication between the UE and the source relay;
receive, from the UE, a measurement report of a subset of candidate relays; and
transmit, to the UE, a relay switch command to switch to a target relay from the subset of candidate relays.
 
15. An apparatus for wireless communication at a base station, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
transmit, to a source relay, a candidate relay configuration including information of candidate relays and a relay measurement configuration comprising a measurement gap configuration indicating that a measurement gap is utilized for reference signals from candidate relays that are not within a bandwidth configured for communication between a user equipment (UE) and the source relay;
receive, from the source relay, a measurement report of reference signals of a subset of candidate relays;
select a target relay from the subset of candidate relays based on the measurement report; and
transmit, to the source relay, a relay switch command for the UE to switch to the target relay.
