1. A UE (user equipment), comprising:
a transceiver to transmit a signal and to receive a signal; and
a processor to control the transceiver,
wherein a maximum output power of the UE is 26 dBm,
wherein the processor determines transmission power based on A-MPR (additional maximum power reduction),
wherein the A-MPR is based on a carrier frequency,
wherein the A-MPR is based on a modulation scheme,
wherein the A-MPR is based on LCRB, startRB and RB allocation,
wherein the transceiver transmits a sidelink signal to another UE with the transmission power,
wherein, based on i) the carrier frequency is 5860 MHz, ii) the LCRB is 10 or more and the LCRB is 15 or less and iii) the startRB is 0 or 1, the A-MPR is less than 24 dB,
wherein, based on i) the carrier frequency is 5860 MHz, ii) the LCRB is 10 or more and the LCRB is 15 or less and iii) the startRB is 2 or 3, the A-MPR is less than 22 dB,
wherein, based on i) the carrier frequency is 5860 MHz, ii) the LCRB is 10 or more and the LCRB is 15 or less and iii) the startRB is 4, the A-MPR is less than 20 dB.
