One disclosure of the present specification provides a UE performing sidelink communication. The UE may comprise: at least one transceiver; at least one processor; and at least one memory that stores instructions and is operably electrically connectable with the at least one processor. An operation performed on the basis of an instruction executed by the at least one processor may comprise the steps of: receiving, via a PSSCH or a PSCCH, a DMRS from another UE; and measuring an RSRP of the DMRS on the basis of RSRP measurement requirements.
