Abstract
An HARQ feedback method and a UE performing the HARQ feedback method are provided. The HARQ feedback method includes transmitting a Physical Sidelink Control Channel (PSCCH)/Physical Sidelink Shared Channel (PSSCH) to a second UE, and receiving a Physical Sidelink Feedback Channel (PSFCH) transmitted by the second UE performing the HARQ feedback according to a decoding result of the PSCCH/PSSCH.
Claims20
A method performed by a first user equipment (UE) in a wireless communication system, the method comprising:
- receiving sidelink control information (SCI);
- identifying a physical sidelink feedback channel (PSFCH) resource for transmitting HARQ feedback information based on the SCI;
- and
- transmitting the HARQ feedback information based on the identified PSFCH resource,
- wherein the identified PSFCH resource corresponds to (UEindexGroup+Aspect)mod NPFSCH,
- wherein the UEindexGroup indicates zero or an identity of the first UE,
- wherein the Aspect indicates a physical layer source identifier, and
- wherein the NPFSCH indicates a number of PSFCH resources available for transmitting the HARQ feedback information.
(canceled)
A method performed by a second user equipment (UE), in a wireless communication system, the method comprising:
- transmitting sidelink control information (SCI) to a first UE;
- and
- receiving HARQ feedback information through a physical sidelink feedback channel (PSFCH),
- wherein a PSFCH resource for the HARQ feedback information corresponds to (UEindexGroup+Aspect)mod NPFSCH,
- wherein the UEindexGroup indicates zero or an identity of the first UE,
- wherein the Aspect indicates a physical layer source identifier, and
- wherein the NPFSCH indicates a number of PSFCH resources available for transmitting the HARQ feedback information.
(canceled)
A first user equipment (UE) in a wireless communication system, the first UE comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to:
- control the transceiver to receive sidelink control information (SCI),
- identify a physical sidelink channel (PSFCH) resource for transmitting HARQ feedback information based on the SCI,
- control the transceiver to transmit the HARQ feedback information based on the identified PSFCH resource,
- wherein the identified PSFCH resource corresponds to (UEindexGroup+Aspect)mod NPFSCH,
- wherein the UEindexGroup indicates zero or an identity of the first UE,
- wherein the Aspect indicates a physical layer source identifier, and
- wherein the NPFSCH indicates a number of PSFCH resources available for transmitting the HARQ feedback information.
(canceled)
A second user equipment (UE) in a wireless communication system, the second UE comprising:
- a transceiver;
- and
- a processor coupled to the transceiver, the processor configured to control transceiver to:
- transmit sidelink control information (SCI) to a first UE;
- and
- receive HARQ feedback information through a physical sidelink feedback channel (PSFCH),
- wherein a PSFCH resource for the HARQ feedback information corresponds to (UEindexGroup+Aspect)mod NPFSCH,
- wherein the UEindexGroup indicates zero or an identity of the first UE,
- wherein the Aspect indicates a physical layer source identifier, and
- wherein the NPFSCH indicates a number of PSFCH resources available for transmitting the HARQ feedback information.
