Abstract
An operation method of a first terminal in a communication system is provided. The method includes transmitting, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal. A configuration information message is received including configuration information of the SL BWP from the base station. The sidelink communication is performed with the second terminal using one or more SL BWPs indicated by the configuration information and in response to determining that reconfiguration of the one or more SL BWPs is necessary, a reconfiguration request message is transmitted to the base station.
Claims17
An operation method of a first terminal in a communication system, comprising:
- transmitting, by a processor, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal;
- receiving, by the processor, a configuration information message including configuration information of the SL BWP from the base station;
- performing, by the processor, the sidelink communication with the second terminal using one or more SL BWPs indicated by the configuration information;
- and
- in response to determining that reconfiguration of the one or more SL BWPs is necessary, transmitting, by the processor, a reconfiguration request message to the base station,
- wherein the configuration information of the SL BWP includes an SL BWP list, and the SL BWP list includes a bandwidth, a subcarrier spacing, resource block (RB) information, and activation information.
An operation method of a base station in a communication system, comprising:
- receiving, by a processor, from a first terminal, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal;
- configuring, by the processor, a plurality of SL BWPs used for the sidelink communication;
- transmitting, by the processor, a configuration information message including configuration information of the plurality of SL BWPs to the first terminal and the second terminal;
- receiving, by the processor, a reconfiguration request message for requesting reconfiguration of the SL BWP from the first terminal;
- reconfiguring, by the processor, one or more new SL BWPs that meet requirements of the first terminal;
- and
- transmitting, by the processor, a reconfiguration information message including reconfiguration information of the one or more new SL BWPs to the first terminal and the second terminal,
- wherein the configuration information of the SL BWP includes an SL BWP list, and the SL BWP list includes a bandwidth, a subcarrier spacing, resource block (RB) information, and activation information.
A first terminal in a communication system, the first terminal comprising:
- a processor;
- and
- a memory storing at least one instruction executable by the processor,
- wherein the at least one instruction causes the processor to:
- transmit, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal;
- receive a configuration information message including configuration information of the SL BWP from the base station;
- perform the sidelink communication with the second terminal using one or more SL BWPs indicated by the configuration information;
- in response to determining that reconfiguration of the one or more SL BWPs is necessary, transmit a reconfiguration request message to the base station;
- receive a reconfiguration information message from the base station, the reconfiguration information message including reconfiguration information of the SL BWP;
- and
- perform the sidelink communication with the second terminal using one or more SL BWPs indicated by the reconfiguration information,
- wherein the configuration information of the SL BWP includes an SL BWP list, and the SL BWP list includes a bandwidth, a subcarrier spacing, resource block (RB) information, and activation information.
