Abstract
An operating method of a first device (100) in a wireless communication system is presented. The method may comprise the steps of: selecting X number of candidate resources on the basis of sensing within a selection window, the X number of candidate resources being included in the active time of an SL DRX configuration related to a second device (200); and selecting a transmission resource for the transmission of a MAC PDU on the basis of the X number of candidate resources.
Claims15
A method for performing, by a first device, wireless communication, the method comprising:
- determining a selection window;
- determining a candidate resource set within the selection window based on sensing;
- based on the candidate resource set not including a resource within an active time of a sidelink (SL) discontinuous reception (DRX) configuration related to a second device, including at least one resource included within the active time in the candidate resource set;
- selecting a transmission resource for a transmission of a medium access control (MAC) protocol data unit (PDU) based on the candidate resource set;
- transmitting, to the second device, sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) through a physical sidelink control channel (PSCCH), based on the transmission resource;
- and
- transmitting, to the second device, the MAC PDU through the PSSCH, based on the transmission resource.
A first device for performing wireless communication, the first device comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- determine a selection window;
- determine a candidate resource set within the selection window based on sensing;
- based on the candidate resource set not including a resource within an active time of a sidelink (SL) discontinuous reception (DRX) configuration related to a second device, include at least one resource included within the active time in the candidate resource set;
- select a transmission resource for a transmission of a medium access control (MAC) protocol data unit (PDU) based on the candidate resource set;
- transmit, to the second device, sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) through a physical sidelink control channel (PSCCH), based on the transmission resource;
- and
- transmit, to the second device, the MAC PDU through the PSSCH, based on the transmission resource.
A device adapted to control a first user equipment (UE), the device comprising:
- one or more processors;
- and
- one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- determine a selection window;
- determine a candidate resource set within the selection window based on sensing;
- based on the candidate resource set not including a resource within an active time of a sidelink (SL) discontinuous reception (DRX) configuration related to a second UE, include at least one resource included within the active time in the candidate resource set;
- select a transmission resource for a transmission of a medium access control (MAC) protocol data unit (PDU) based on the candidate resource set;
- transmit, to the second UE, sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) through a physical sidelink control channel (PSCCH), based on the transmission resource;
- and
- transmit, to the second UE, the MAC PDU through the PSSCH, based on the transmission resource.
