Abstract
A method in which a first apparatus performs wireless communication and an apparatus supporting the same are provided. The method may include: receiving information related to a physical sidelink feedback channel (PSFCH) resource from a base station; receiving a physical sidelink shared channel (PSSCH) from a second apparatus; and transmitting a PSFCH related to the PSSCH to the second apparatus. Here, the information related to the PSFCH resource may include, for example, information related to a resource block (RB) available for the first apparatus to transmit the PSFCH.
Claims14
A method in which a first apparatus performs wireless communication, the method comprising:
- receiving, from a base station, first information related to a set of resource blocks (RBs) available for the first apparatus to transmit a physical sidelink feedback channel (PSFCH) and second information related to a number of cyclic shifts available for the first apparatus to transmit the PSFCH;
- receiving, from a second apparatus, a physical sidelink shared channel (PSSCH);
- determining a PSFCH resource related the PSSCH, based on the first information related to the set of RBs and the second information related to the number of cyclic shifts;
- and
- transmitting, to the second apparatus, Hybrid Automatic Repeat Request (HARQ) information based on the PSFCH resource.
A first apparatus configured to perform wireless communication, the first apparatus 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 based on the one or more processors executing the instructions, the one or more processors control the first apparatus to:
- receive, from a base station, first information related to a set of resource blocks (RBs) available for the first apparatus to transmit a physical sidelink feedback channel (PSFCH) and second information related to a number of cyclic shifts available for the first apparatus to transmit the PSFCH;
- receive, from a second apparatus, a physical sidelink shared channel (PSSCH);
- determine a PSFCH resource related the PSSCH, based on the first information related to the set of RBs and the second information related to the number of cyclic shifts;
- and
- transmit, to the second apparatus, Hybrid Automatic Repeat Request (HARQ) information based on the PSFCH resource.
An apparatus configured to control a first user equipment (UE), the apparatus comprising:
- one or more processors;
- and
- one or more memories operatively connected to the one or more processors and storing instructions,
- wherein based on the one or more processors executing the instructions, the one or more processors control the first UE to:
- receive, from a base station, first information related to a set of resource blocks (RBs) available for the first UE to transmit a physical sidelink feedback channel (PSFCH) and second information related to a number of cyclic shifts available for the first UE to transmit the PSFCH;
- receive, from a second UE, a physical sidelink shared channel (PSSCH);
- determine a PSFCH resource related the PSSCH, based on the first information related to the set of RBs and the second information related to the number of cyclic shifts;
- and
- transmit, to the second UE, Hybrid Automatic Repeat Request (HARQ) information based on the PSFCH resource.
