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.
Claims12
A method for performing wireless communication by a first device, the method comprising:
- receiving, from a second device through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH);
- receiving, from the second device through the PSSCH, second SCI and data;
- determining that the second SCI has a first type SCI format among at least a first type SCI format and a second type SCI format;
- wherein the first type of SCI format includes (i) information representing that hybrid automatic repeat request (HARQ) feedback is enabled, (ii) a zone ID, and (iii) a communication range requirement;
- wherein the second type of SCI format includes (i) information representing that HARQ feedback is enabled (ii) a CSI request (iii) a cast type indicator;
- and
- wherein the HARQ feedback mode is negative-only feedback mode and cast type is groupcast due to the second SCI having the first type SCI format;
- and
- transmitting, to the second device through a physical sidelink feedback channel (PSFCH), negative acknowledgement (NACK) feedback in response to the PSSCH not being successfully decoded, based on the determined HARQ feedback mode.

A first device configured to perform 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 control the one or more transceivers to:
- receive, from a second device through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH);
- receive, from the second device through the PSSCH, second SCI and data;
- determine that the second SCI has a first type SCI format among at least a first type SCI format and a second type SCI format;
- wherein the first type of SCI format includes (i) information representing that hybrid automatic repeat request (HARQ) feedback is enabled, (ii) a zone ID, and (iii) a communication range requirement;
- wherein the second type of SCI format includes (i) information representing that HARQ feedback is enabled (ii) a CSI request (iii) a cast type indicator;
- and
- wherein the HARQ feedback mode is negative-only feedback mode and cast type is groupcast due to the second SCI having the first type SCI format;
- and
- transmit, to the second device through a physical sidelink feedback channel (PSFCH), a negative acknowledgement (NACK) feedback in response to the PSSCH not being successfully decoded, based on the determined HARQ feedback mode.
11 more elements
A device configured 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:
- receive, from a second UE through a physical sidelink control channel (PSCCH), first sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH);
- receive, from the second UE through the PSSCH, second SCI and data;
- determine that the second SCI has a first type SCI format among at least a first type SCI format and a second type SCI format;
- hybrid automatic repeat request (HARQ) feedback wherein the first type of SCI format includes (i) information representing that hybrid automatic repeat request (HARQ) feedback is enabled, (ii) a zone ID, and (iii) a communication range requirement;
- wherein the second type of SCI format includes (i) information representing that HARQ feedback is enabled (ii) a CSI request (iii) a cast type indicator;
- and
- wherein the HARQ feedback mode is negative-only feedback mode and cast type is groupcast due to the second SCI having the first type SCI format;
- and
- transmit, to the second device through a physical sidelink feedback channel (PSFCH), a negative acknowledgement (NACK) feedback in response to the PSSCH not being successfully decoded, based on the determined HARQ feedback mode.
