Abstract
Provided are a method by which a first device performs wireless communication and an apparatus for supporting same. The method may comprise the steps of: determining a first PSSCH resource selected by a second device; selecting a second PSSCH resource; and transmitting a PSSCH by using the second PSSCH resource. Here, a PSFCH resource related to the second PSSCH resource may not overlap a PSFCH resource related to the first PSSCH resource.
Claims7
A method for performing wireless communication by a first device, the method comprising:
- triggering a resource selection;
- determining a selection window, based on a resource selection being triggered;
- selecting a first physical sidelink shared channel (PSSCH) resource within the selection window;
- determining (i) a first physical sidelink feedback channel (PSFCH) slot related to the first PSSCH resource and (ii) at least one PSSCH resource related to the first PSFCH slot;
- performing sidelink (SL) transmission, based on the first PSSCH resource;
- and
- transmitting, to a second device, assistance information related to the at least one PSSCH resource not preferred by the first device,
- wherein a second PSSCH resource selected by the second device is not included in the at least one PSSCH resource, and
- wherein a second PSFCH slot related to the second PSSCH resource is different from the first PSFCH slot.
A first apparatus configured to perform wireless communication, the first apparatus comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- triggering a resource selection;
- determining a selection window, based on a resource selection being triggered;
- selecting a first physical sidelink shared channel (PSSCH) resource within the selection window;
- determining (i) a first physical sidelink feedback channel (PSFCH) slot related to the first PSSCH resource and (ii) at least one PSSCH resource related to the first PSFCH slot;
- performing sidelink (SL) transmission, based on the first PSSCH resource;
- and
- transmitting, to a second device, assistance information related to the at least one PSSCH resource not preferred by the first apparatus,
- wherein a second PSSCH resource selected by the second device is not included in the at least one PSSCH resource, and
- wherein a second PSFCH slot related to the second PSSCH resource is different from the first PSFCH slot.
A processing device configured to control a first apparatus to perform wireless communication, the processing device comprising:
- at least one processor;
- and
- at least one memory connected to the at least one processor and storing instructions that, based on being executed, cause the at least one processor to perform operations comprising:
- triggering a resource selection;
- determining a selection window, based on a resource selection being triggered;
- selecting a first physical sidelink shared channel (PSSCH) resource within the selection window;
- determining (i) a first physical sidelink feedback channel (PSFCH) slot related to the first PSSCH resource and (ii) at least one PSSCH resource related to the first PSFCH slot;
- performing sidelink (SL) transmission, based on the first PSSCH resource;
- and
- transmitting, to a second device, assistance information related to the at least one PSSCH resource not preferred by the first apparatus,
- wherein a second PSSCH resource selected by the second device is not included in the at least one PSSCH resource, and
- wherein a second PSFCH slot related to the second PSSCH resource is different from the first PSFCH slot.
