Abstract
Proposed is a method for performing a sidelink operation in a wireless communication system, the method being performed by a terminal. The method comprises: selecting a preferred resource pool from among a plurality of resource pools, wherein the preferred resource pool is one of a first resource pool including a physical sidelink feedback channel (PSFCH) resource and a second resource pool without the PSFCH resource; and, on the basis of a re-selection condition, performing the sidelink operation on the first resource pool or the second resource pool.
Claims12
A method for transmitting data in a wireless communication system, the method performed by a user equipment (UE) and comprising:
- selecting a pool of resources among pools of resources, and
- transmitting the data based on the selected pool of resources,
- wherein the pools of resources comprise i) at least one pool of resources not configured with physical sidelink feedback channel (PSFCH) resources and ii) at least one pool of resources configured with PSFCH resources,
- wherein the UE selects any pool of resources among the pools of resources for data for which hybrid automatic repeat request (HARQ) feedback is disabled, and
- wherein the UE selects any pool of resources configured with PSFCH resources among the pools of resources for data for which HARQ feedback is enabled.
A user equipment (UE) comprising:
- a transceiver transmitting and receiving radio signals;
- and
- a processor being operatively connected to the transceiver,
- wherein the processor is adapted to:
- select a pool of resources among pools of resources, and
- transmit data based on the selected pool of resources,
- wherein the pools of resources comprise i) at least one pool of resources not configured with physical sidelink feedback channel (PSFCH) resources and ii) at least one pool of resources configured with PSFCH resources,
- wherein the processor selects any pool of resources among the pools of resources for data for which hybrid automatic repeat request (HARQ) feedback is disabled, and
- wherein the processor selects any pool of resources configured with PSFCH resources among the pools of resources for data for which HARQ feedback is enabled.
A processor for a wireless communication device in a wireless communication system,
- wherein the processor is adapted to control the wireless communication device to:
- select a pool of resources among pools of resources, and
- transmit data based on the selected pool of resources,
- wherein the pools of resources comprise i) at least one pool of resources not configured with physical sidelink feedback channel (PSFCH) resources and ii) at least one pool of resources configured with PSFCH resources,
- wherein the processor selects any pool of resources among the pools of resources for data for which hybrid automatic repeat request (HARQ) feedback is disabled, and
- wherein the processor selects any pool of resources configured with PSFCH resources among the pools of resources for data for which HARQ feedback is enabled.
