Abstract
A method for performing wireless communication by a first device and a device for supporting same are provided. The method may include receiving, from a second device, a physical sidelink control channel (PSCCH) including a first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH); receiving, from the second device, the PSSCH including a second SCI; and transmitting, to the second device, a hybrid automatic repeat request (HARQ) feedback through a physical sidelink feedback channel (PSFCH) in response to the PSSCH based on a format of the second SCI.
Claims10
A method comprising:
- receiving, on a physical sidelink control channel (PSCCH), a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH);
- receiving, on the PSSCH, a second SCI and data;
- and
- transmitting, on a physical sidelink feedback channel (PSFCH), hybrid automatic repeat request (HARQ)—acknowledgement (ACK) information including a negative acknowledgement (NACK) of the data, based on i) negative-only acknowledgement indicated by the second SCI, and ii) the data being not successfully decoded,
- wherein the second SCI comprises a zone identifier (ID) and information related to a communication range requirement.
A user equipment (UE) 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 perform operations comprising:
- receiving, on a physical sidelink control channel (PSCCH), a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH);
- receiving, on the PSSCH, a second SCI and data;
- and
- transmitting, on a physical sidelink feedback channel (PSFCH), hybrid automatic repeat request (HARQ)—acknowledgement (ACK) information including a negative acknowledgement (NACK) of the data, based on i) negative-only acknowledgement indicated by the second SCI, and ii) the data being not successfully decoded,
- wherein the second SCI comprises a zone identifier (ID) and information related to a communication range requirement.
An apparatus 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 perform operations comprising:
- receiving, on a physical sidelink control channel (PSCCH), a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH);
- receiving, on the PSSCH, a second SCI and data;
- and
- transmitting, on a physical sidelink feedback channel (PSFCH), hybrid automatic repeat request (HARQ)—acknowledgement (ACK) information including a negative acknowledgement (NACK) of the data, based on i) negative-only acknowledgement indicated by the second SCI, and ii) the data being not successfully decoded,
- wherein the second SCI comprises a zone identifier (ID) and information related to a communication range requirement.
