Abstract
One embodiment of the present invention relates to a method whereby a first terminal transmits and receives sidelink signals in a wireless communication system, the sidelink signal transmission and reception method comprising the steps of: selecting a resource for executing a second transmission, the selection of which is restricted by the position of a resource selected for a first transmission; and executing the second transmission in the resource selected for the second transmission.
Claims11
A method of performing a sidelink communication by a user equipment (UE) in a wireless communication system, the method comprising:
- selecting a first resource for performing a first signal transmission based on channel sensing on a sidelink resource pool;
- selecting a second resource for performing a second signal transmission within the sidelink resource pool based on a time domain position of the first resource selected for the first signal transmission;
- and
- performing the first signal transmission and the second signal transmission based on the first resource and the second resource,
- wherein the first signal transmission is related to a new transmission, and the second signal transmission is related to a re-transmission, and
- wherein in the selection of the second resource, the UE randomly selects the second resource within the sidelink resource pool while excluding the first resource in time domain such that the second resource is located within a specific number of subframes from a subframe at which the first resource is located, but the second resource is not located at a same time domain position as the first time resource.
A user equipment (UE) configured to perform sidelink communication, the UE comprising:
- a transceiver including a transmitter and a receiver;
- and
- a processor configured to:
- select a first resource for performing a first signal transmission based on channel sensing on a sidelink resource pool;
- select a second resource for performing a second signal transmission within the sidelink resource pool based on a time domain position of the first resource selected for the first signal transmission;
- and
- perform, through the transceiver, the first signal transmission and the second signal transmission based on the first resource and the second resource,
- wherein the first signal transmission is related to a new transmission, and the second signal transmission is related to a re-transmission, and
- wherein in the selection of the second resource, the processor randomly selects the second resource within the sidelink resource pool while excluding the first resource in time domain such that the second resource is located within a specific number of subframes from a subframe at which the first resource is located, but the second resource is not located at a same time domain position as the first time resource.
A device for processing a signal for a sidelink communication, the device comprising:
- a memory configured to store instructions;
- and
- a processor configured to perform operations by executing the instructions, the operations comprising:
- selecting a first resource for performing a first signal transmission based on channel sensing on a sidelink resource pool;
- selecting a second resource for performing a second signal transmission within the sidelink resource pool based on a time domain position of the first resource selected for the first signal transmission;
- and
- performing the first signal transmission and the second signal transmission based on the first resource and the second resource,
- wherein the first signal transmission is related to a new transmission, and the second signal transmission is related to a re-transmission, and
- wherein in the selection of the second resource, the processor randomly selects the second resource within the sidelink resource pool while excluding the first resource in time domain such that the second resource is located within a specific number of subframes from a subframe at which the first resource is located, but the second resource is not located at a same time domain position as the first time resource.
