1. One or more non-transitory, computer-readable media having instructions that, when executed, cause processing circuitry to:
establish a connection with a target user equipment (UE) through a relay UE;
detect a trigger to perform a relay UE reselection;
select, as a predetermined threshold, whichever is greater of a first threshold based on a security policy of a source UE and a second threshold based on a security policy of the target UE;
detect a candidate relay UE having a security capability that is equal to or greater than the predetermined threshold;
generate a relay UE reselection request, the relay UE reselection request to include an identifier and the security capability of the candidate relay UE; and
output the relay UE reselection request for transmission to the target UE to perform the relay UE reselection.
