Abstract
A disclosure of the present specification provides a method for performing communication by a base station. The method may comprise the steps of: transmitting a TA offset for UL communication to a UE; determining an SCS for SL communication; and transmitting SL configuration information including information on the SCS for SL communication to the UE.
Claims8
A method for performing communication, the method performed by a base station and comprising:
- transmitting a timing advance (TA) offset for uplink (UL) communication to a user equipment (UE);
- determining a subcarrier spacing (SCS) for sidelink (SL) communication;
- and
- transmitting SL configuration information including information about the SCS for SL communication, to the UE,
- wherein the SCS for SL communication is determined based on information related to a distance, the TA offset for UL communication, and the TA offset for SL communication, and
- wherein the information related to the distance is a cell radius of the base station or a distance between the base station and the UE.
A method for performing communication, the method performed by a User Equipment (UE) and comprising:
- receiving, from a base station, a Timing Advance (TA) offset for uplink (UL) communication;
- receiving, from the base station, sidelink (SL) configuration information comprising information about a subcarrier spacing (SCS) for SL communication;
- and
- transmitting, based on the SL configuration information, an SL signal,
- wherein the SCS for SL communication is determined, by the base station, based on information related to a distance, a TA offset for UL communication, and a TA offset for SL communication, and
- wherein the information related to the distance is a cell radius of the base station or a distance between the base station and the UE.
A User Equipment (UE) for performing communication, the UE comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory that stores instructions and is operably electrically connectable with the at least one processor,
- wherein the operations performed based on the instructions being executed by the at least one processor include:
- receiving, from a base station, a Timing Advance (TA) offset for uplink (UL) communication;
- receiving, from the base station, sidelink (SL) configuration information comprising information about a subcarrier spacing (SCS) for SL communication;
- and
- transmitting, based on the SL configuration information, an SL signal,
- wherein the SCS for SL communication is determined, by the base station, based on information related to a distance, a TA offset for UL communication, and a TA offset for SL communication, and
- wherein the information related to the distance is a cell radius of the base station or a distance between the base station and the UE.
