and PSCCH, the reference signals are generated based on a fixed base sequence, cyclic shift, and orthogonal cover code. For V2X sidelink communication, cyclic shift for PSCCH is randomly selected in each transmission [6]. Vehicle-to-Everything (V2X) Communications 817 For in-coverage operation, the power spectral density of the sidelink transmissions is deter- mined by the eNB. For measurement on the sidelink, the following basic UE measurement quantities are defined [18,19]: Sidelink reference signal received power (S-RSRP) is defined as the linear average over the power contributions [in (Watts)] of the resource elements that carry DM-RSs associ- ated with physical sidelink broadcast channel (PSBCH), within the six middle-band PRBs of the relevant subframes. The reference point for the S-RSRP is the antenna connector of the UE. The reported value must not be lower than the corresponding S- RSRP of any of the individual diversity branches, if receive diversity is utilized by the Sidelink discovery reference signal received power (SD-RSRP) is defined as the linear average over the power contributions (in [Watts]) of the resource elements that carry DM-RSs associated with PSDCH for which CRC has been validated. The reference point for the SD-RSRP is the antenna connector of the UE. If receive diversity is used by the UE, the reported value will be lower than the corresponding SD-RSRP of any of the individual diversity branches. PSSCH reference signal received power (PSSCH-RSRP) is defined as the linear average over the power contributions [in (Watts)] of the resource elements that carry DM-RSs associated with PSSCH, within the PRBs indicated by the associated PSCCH. The refer- ence point for the PSSCH-RSRP is the antenna connector of the UE. If receive diversity is used by the UE, the reported value must not be lower than the corresponding PSSCH-RSRP of any of the individual diversity branches. Sidelink reference signal strength indicator (S-RSSI) is defined as the linear average of the total received power [in (W
