Abstract
One embodiment of the present invention relates to a method whereby a sidelink terminal transmits a signal in a wireless communications system, the signal transmission method comprising the steps of: mapping data to symbols in a slot; and transmitting a signal after mapping the data, wherein whether to map data to a predetermined symbol in the slot and the interval of mapping are determined on the basis of subcarrier spacing and a frequency range.
Claims13
A method for transmitting a signal by a sidelink user equipment (UE) in a wireless communications system, the method comprising:
- performing, by the sidelink UE, sensing within a sensing window;
- excluding, by the sidelink UE, a resource related to a transmission of another sidelink UE;
- after excluding the resource, selecting, by the sidelink UE, a transmission resource within a selection window;
- mapping, by the sidelink UE, data to symbols in a slot of the transmission resource;
- and
- transmitting, by the sidelink UE, a signal after mapping the data,
- wherein whether to map data to a predetermined symbol in the slot and a mapping interval are determined based on a subcarrier spacing and a frequency range (FR), and
- wherein the sidelink UE uses a second time duration excluding a first time duration from a symbol duration corresponding to the subcarrier spacing, for data transmission, and the first time duration is a smallest value of values greater than Tx/Rx switching time in the FR among integer multiples of values obtained by dividing the symbol duration by the mapping interval.
A sidelink user equipment (UE) for transmitting or receiving a signal in a wireless communication system, the sidelink UE comprising:
- a memory;
- and
- a processor coupled to the memory,
- wherein the processor is configured to perform operations for the sidelink UE, the operations including:
- performing sensing within a sensing window;
- excluding a resource related to a transmission of another sidelink UE;
- after excluding the resource, selecting a transmission resource within a selection window;
- mapping data to symbols in a slot;
- and
- transmitting a signal after mapping the data,
- wherein whether to map data to a predetermined symbol in the slot and a mapping interval are determined based on a subcarrier spacing and a frequency range (FR), and
- wherein the sidelink UE uses a second time duration excluding a first time duration from a symbol duration corresponding to the subcarrier spacing, for data transmission, and the first time duration is a smallest value of values greater than Tx/Rx switching time in the FR among integer multiples of values obtained by dividing the symbol duration by the mapping interval.
