Abstract
Provided are a method by which a first apparatus configures a bandwidth part (BWP) and an apparatus for supporting same. The method may comprise the steps of: configuring a first BWP related to communication between the first apparatus and a base station; and configuring a second BWP related to sidelink communication between the first apparatus and a second apparatus. Here, numerology of the first BWP and numerology of the second BWP may be the same.
Claims19
A method performed by a first device in a wireless communication system, the method comprising:
- obtaining first configuration information related to a universal mobile telecommunications system (UMTS) user (Uu) bandwidth part (BWP) related to communication between the first device and a base station;
- obtaining second configuration information related to a sidelink (SL) BWP related to SL communication between the first device and a second device;
- transmitting, to the base station, information related to a BWP switching between the Uu BWP and the SL BWP, wherein the BWP switching is either that the SL BWP is switched to the Uu BWP or that the Uu BWP is switched to the SL BWP;
- receiving, from the base station, information related to a time period in which the BWP switching is allowed;
- and
- performing the BWP switching within the time period in which the BWP switching is allowed,
- wherein the information related to the time period in which the BWP switching is allowed is determined based on the information related to the BWP switching.
A first device configured to perform wireless communication, the first device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- obtaining first configuration information related to a universal mobile telecommunications system (UMTS) user (Uu) bandwidth part (BWP) related to communication between the first device and a base station;
- obtaining second configuration information related to a sidelink (SL) BWP related to SL communication between the first device and a second device;
- transmitting, to the base station, information related to a BWP switching between the Uu BWP and the SL BWP, wherein the BWP switching is either that the SL BWP is switched to the Uu BWP or that the Uu BWP is switched to the SL BWP;
- receiving, from the base station, information related to a time period in which the BWP switching is allowed;
- and
- performing the BWP switching within the time period in which the BWP switching is allowed,
- wherein the information related to the time period in which the BWP switching is allowed is determined based on the information related to the BWP switching.
