Abstract
The present disclosure is to sense a resource for sidelink communication in a wireless communication system. A method of operating a terminal in a wireless communication system may comprise receiving sidelink data through a physical sidelink shared channel (PSSCH) from another terminal and transmitting a feedback signal for the sidelink data through a physical sidelink feedback channel (PSFCH). The feedback signal may comprise hybrid automatic repeat request (HARQ)-acknowledge (ACK)/negative-ACK (NACK) information corresponding to the sidelink data and information related to a location of the PSSCH, and the feedback signal may be transmitted using a plurality of beams.

A method of operating a terminal in a wireless communication system, the method comprising:
- receiving sidelink data through a physical sidelink shared channel (PSSCH) from another terminal;
- and
- transmitting a feedback signal for the sidelink data through a physical sidelink feedback channel (PSFCH),
- wherein the feedback signal comprises hybrid automatic repeat request (HARQ)-acknowledge (ACK)/negative-ACK (NACK) information corresponding to the sidelink,
- wherein the feedback signal further comprises information related to a location of the PSSCH slot in which the sidelink data is received and is transmitted using a plurality of beams,
- wherein the information related to the location of the PSSCH slot indicates a time resource indicator value (TRIV) included in sidelink control information (SCI) for the PSSCH, and
- wherein the information related to the location of the PSSCH slot is transmitted in an area assigned to indicate the TRIV in the PSFCH.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a processor connected to the transceiver,
- wherein the processor performs control to:
- receive sidelink data through a physical sidelink shared channel (PSSCH) from another terminal;
- and
- transmit a feedback signal for the sidelink data through a physical sidelink feedback channel (PSFCH),
- wherein the feedback signal comprises hybrid automatic repeat request (HARQ)-acknowledge (ACK)/negative-ACK (NACK) information corresponding to the sidelink data,
- wherein the feedback signal further comprises information related to a location of the PSSCH slot in which the sidelink data is received and is transmitted using a plurality of beams,
- wherein the information related to the location of the PSSCH slot indicates a time resource indicator value (TRIV) included in sidelink control information (SCI) for the PSSCH, and
- wherein the information related to the location of the PSSCH slot is transmitted in an area assigned to indicate the TRIV in the PSFCH.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a processor connected to the transceiver,
- wherein the processor performs control to:
- receive a feedback signal transmitted through a physical sidelink feedback channel (PSFCH) from one of other terminals performing sidelink communication;
- identify information related to a location of a physical sidelink shared channel (PSSCH) slot corresponding to the PSFCH based on the feedback signal;
- and
- transmit sidelink data using a selected resource based on the information,
- wherein the feedback signal comprises hybrid automatic repeat request (HARQ)-acknowledge (ACK)/negative-ACK (NACK) information corresponding to sidelink data transmitted between the other terminals and information related to a location of the PSSCH slot in which the sidelink data is received by one of the other terminals,
- wherein the feedback signal is transmitted using a plurality of beams,
- wherein the information related to the location of the PSSCH slot indicates a time resource indicator value (TRIV) included in sidelink control information (SCI) for the PSSCH, and
- wherein the information related to the location of the PSSCH slot is transmitted in an area assigned to indicate the TRIV in the PSFCH.
