Communication method and device

Abstract

To improve the communication success rate, a communication method and apparatus are provided that flexibly determine an appropriate maximum output power setting and appropriately determine the transmit power for uplink transmissions and / or sidelink transmissions. [Solution] The communication method includes the steps of: determining whether a first uplink transmission resource overlaps with a first sidelink transmission resource in the time domain; determining a first set maximum output power based on a first maximum power reduction if the first uplink transmission resource overlaps with a first sidelink transmission resource in the time domain, wherein the first maximum power reduction is a maximum power reduction corresponding to a concurrent mode; and determining the transmission power of the first uplink transmission and the transmission power of the first sidelink transmission based on the first set maximum output power.
