Abstract
The disclosure relates to a communication method and a system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
Claims16
A method performed by a first user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station, a radio resource control (RRC) message including information related to sidelink transmission power;
- determining sidelink transmission power, based on the information;
- and
- transmitting a sidelink control channel and a sidelink data channel, based on the determined sidelink transmission power,
- wherein the information includes at least one of downlink path loss-related information or sidelink path loss-related information, and
- wherein the sidelink transmission power is determined based on PPSSCH(i)=min(PCMAX,PMAX,CBR,min(PPSSCH,D(i),PPSSCH,SL(i))) [dBm].
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting, to a first user equipment (UE), a radio resource control (RRC) message including information related to sidelink transmission power;
- and
- receiving, from the first UE, a sidelink control channel and a sidelink data channel, based on sidelink transmission power,
- wherein the sidelink transmission power is determined based on the information, and
- wherein the information includes at least one of downlink path loss-related information or sidelink path loss-related information, and
- wherein the sidelink transmission power is determined based on PPSSCH(i)=min(PCMAX,PMAX,CBR,min(PPSSCH,D(i),PPSSCH,SL(i))) [dBm].
A first user equipment (UE) comprising:
- a transceiver configured to transmit or receive at least one signal;
- and
- at least one processor coupled to the transceiver,
- wherein the at least one processor is configured to:
- receive, from a base station, a radio resource control (RRC) message including information related to sidelink transmission power,
- determine sidelink transmission power, based on the information, and
- transmit a sidelink control channel and a sidelink data channel, based on the determined sidelink transmission power, and
- wherein the information includes at least one of downlink path loss-related information or sidelink path loss-related information, and
- wherein the sidelink transmission power is determined based on PPSSCH(i)=min(PCMAX,PMAX,CBR,min(PPSSCH,D(i),PPSSCH,SL(i))) [dBm].
A base station comprising:
- a transceiver configured to transmit or receive at least one signal;
- and
- at least one processor coupled to the transceiver,
- wherein the at least one processor is configured to:
- transmit, to a first user equipment (UE), a radio resource control (RRC) message including information related to sidelink transmission power, and
- receive, from the first UE, a sidelink control channel and a sidelink data channel, based on sidelink transmission power,
- wherein the sidelink transmission power is determined based on the information,
- wherein the information includes at least one of downlink path loss-related information or sidelink path loss-related information, and
- wherein the sidelink transmission power is determined based on PPSSCH(i)=min(PCMAX,PMAX,CBR,min(PPSSCH,D(i),PPSSCH,SL(i))) [dBm].
