5 Claims

1. A User Equipment (UE) for performing sidelink communication, the UE comprising:

at least one transceiver;

at least one processor; and

at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

performing a Physical Sidelink Control Channel - Reference Signal Received Power (PSCCH-RSRP) measurement or a Physical Sidelink Shared Channel-Reference Signal Received Power (PSSCH-RSRP) measurement based on New Radio (NR) V2X operating band n38 or n47,

wherein RSRP measurement accuracy requirements apply to the UE,

wherein the RSRP accuracy requirements include an accuracy of RSRP being ±4.5dB,

wherein, the PSCCH-RSRP or the PSSCH-RSRP, as measured, is greater than or equal to a minimum total received power density, and

wherein for New Radio (NR) Vehicle-to-Everything (V2X) operating band n38, the minimum total received power density is equal to:

−120.5 decibel milliwatt (dBm), based on a subcarrier spacing (SCS) of 15 kilohertz (kHz),

−117.5 dBm, based on a SCS of 30kHz, and

−114.5 dBm, based on a SCS of 60kHz,

wherein for NR V2X operating band n47, the minimum total received power density is equal to:

−116.5 dBm, based on a SCS of 15 kHz,

−113.5 dBm, based on a SCS of 30 kHz, and

−110.5dBm, based on a SCS of 60 kHz.

4. A method of performing sidelink communication by a user equipment (UE), the method comprising:

performing a Physical Sidelink Control Channel-Reference Signal Received Power (PSCCH-RSRP) measurement or Physical Sidelink Shared Channel-RSRP (PSSCH-RSRP) measurement based on New Radio (NR) V2X operating band n38 or n47,

wherein RSRP measurement accuracy requirements apply to the UE,

wherein the RSRP accuracy requirements include an accuracy of RSRP being ±4.5 dB,

wherein, the PSCCH-RSRP or the PSSCH-RSRP, as measured, is greater than or equal to a minimum total received power density, and

wherein for New Radio (NR) Vehicle-to-Everything (V2X) operating band n38, the minimum total received power density is equal to:

−120.5 decibel milliwatt (dBm), based on a subcarrier spacing (SCS) of 15 kilohertz (kHz),

−117.5 dBm, based on a SCS of 30 kHz, and

−114.5 dBm, based on a SCS of 60 kHz,

wherein for NR V2X operating band n47, the minimum total received power density is equal to:

−116.5 dBm, based on a SCS of 15 kHz,

−113.5 dBm, based on a SCS of 30 kHz, and

−110.5 dBm, based on a SCS of 60 kHz.
