US 11,388,678 B2 · Method and apparatus for controlling transmission power in wireless communication system

Abstract

A method and apparatus are provided. The method of configuring a sidelink transmission power by a V2X user equipment (UE) in a wireless communication system includes receiving, from a base station (BS), first parameter for sidelink link quality or second parameter for downlink link quality, configuring, the transmission power for at least one of a sidelink control channel or a sidelink data channel based on sidelink pathloss or downlink pathloss according to the receiving of the first parameter or the second parameter, and transmitting, to a receiving V2X UE, the sidelink control channel or the sidelink data channel based on the configured transmission power.

Dependent claims

A method performed by a vehicle-to-everything (V2X) user equipment (UE) in a wireless communication system, the method comprising:

receiving, from a base station, one or more first parameters for sidelink pathloss based power control and one or more second parameters for downlink pathloss based power control;
determining a transmission power for a physical sidelink shared channel (PSSCH) transmission, based on the one or more first parameters and the one or more second parameters;
and
performing the PSSCH transmission to a receiving V2X UE, based on the transmission power,
wherein the transmission power includes:
a first transmission power for a first PSSCH transmission in one or more first symbols where a physical sidelink control channel (PSCCH) is not transmitted, and
a second transmission power for a second PSSCH transmission in one or more second symbols where the PSCCH is transmitted.
