1. A UE (user equipment), comprising:
at least one transceiver to transmit a signal and to receive a signal; and
at least one processor to control the at least one transceiver,
wherein the at least one processor is configured to acquire a network signal (NS) 52,
wherein the at least one processor is configured to determine A-MPR (additional maximum power reduction), based on the NS 52,
wherein the at least one processor is configured to determine transmission power for a sidelink signal, based on the A-MPR,
wherein the at least one transceiver is configured to transmit the sidelink signal with the transmission power via a modulation type, to another UE,
wherein the sidelink signal is transmitted through a PSSCH (Physical Sidelink Shared Channel) or a PSCCH (Physical Sidelink Control Channel),
wherein the sidelink signal is transmitted through a band having a center frequency of 5885 MHz and a bandwidth of 40 MHz,
wherein the sidelink signal is transmitted through allocated RBs (Resource Blocks), which belong to one among region 1, region 2 and region 3,
wherein the modulation type is one among QPSK (Quadrature Phase Shift Keying), 16QAM (Quadrature Amplitude Modulation), 64QAM and 256QAM,
wherein the A-MPR is determined based on the allocated RBs and the modulation type,
wherein the A-MPR is less than or equal to 8 dB, based on the modulation type being the QPSK and the allocated RBs belonging to the region 2.
