Abstract
Provided are methods and apparatuses for transmitting sidelink hybrid automatic repeat request (HARQ) feedback information. The method of a receiver user equipment (UE) includes: receiving configuration information on a physical sidelink feedback channel (PSFCH) resource set, receiving a physical sidelink shared channel (PSSCH) from a transmitter UE, determining a PSFCH resource used for transmitting the HARQ feedback information in response to the PSSCH in the PSFCH resource set based on pre-configured identification information, and transmitting the HARQ feedback information using the PSFCH resource.
Claims12
A method of a receiver user equipment (UE) for transmitting hybrid automatic repeat request (HARQ) feedback information, the method comprising:
- receiving configuration information on a physical sidelink feedback channel (PSFCH) resource set;
- receiving a physical sidelink shared channel (PSSCH) from a transmitter UE;
- receiving a source identifier (ID) of the transmitter UE through the PSSCH from the transmitter UE;
- determining a PSFCH resource used for transmitting the HARQ feedback information in response to the PSSCH in the PSFCH resource set;
- and
- transmitting the HARQ feedback information using the PSFCH resource,
- wherein the PSFCH resource is determined based on the received source ID of the transmitter UE.
A method of a transmitter user equipment (UE) for receiving hybrid automatic repeat request (HARQ) feedback information, the method comprising:
- transmitting a physical sidelink shared channel (PSSCH) to a receiver UE;
- transmitting a source identifier (ID) of the transmitter UE through the PSSCH to the receiver UE;
- and
- receiving the HARQ feedback information in response to the PSSCH using a physical sidelink feedback channel (PSFCH) resource in a PSFCH resource set,
- wherein the PSFCH resource is determined based on the transmitted source ID of the transmitter UE.
A receiver user equipment (UE) for transmitting hybrid automatic repeat request (HARQ) feedback information, the receiver UE comprising:
- a receiver configured to receive configuration information on a physical sidelink feedback channel (PSFCH) resource set, receive a physical sidelink shared channel (PSSCH) from a transmitter UE, and receive a source identifier (ID) of the transmitter UE through the PSSCH from the transmitter UE;
- a controller configured to determine a PSFCH resource used for transmitting the HARQ feedback information in response to the PSSCH in the PSFCH resource set;
- and
- a transmitter configured to transmit the HARQ feedback information using the PSFCH resource,
- wherein the PSFCH resource is determined based on the received source ID of the transmitter UE.
