Abstract
The disclosure describes a method for transmitting a signal in a wireless access system and a device supporting the same. More particular, to carrier sensing methods, specifically methods for performing a channel access procedure (CAP), methods for selecting a representative frequency resource, methods for transmitting a data burst, and devices supporting the same.
Claims8
A method for an apparatus in a wireless communication system, the method comprising:
- selecting a first frequency resource among a plurality of frequency resources;
- performing a first channel access procedure on the first frequency resource;
- transmitting, based on the first channel access procedure, a first transmission burst on the first frequency resource after the first frequency resource is determined to be idle and after a random number decrements to 0 based on decrementing the random number by 1 for each slot duration related to the first frequency resource determined to be idle, wherein the random number is randomly obtained among a value included in a contention window;
- performing a second channel access procedure on a second frequency resource among the plurality of frequency resources for a predetermined time duration immediately before the transmission of the first transmission burst, wherein the second frequency resource is different from the first frequency resource;
- and
- transmitting, based on the second channel access procedure, a second transmission burst on the second frequency resource after the second frequency resource is determined to be idle for the predetermined time duration.
3 more elements
An apparatus in a wireless communication system, the apparatus comprising:
- a memory;
- and
- at least one processor coupled with the memory,
- wherein the at least one processor is configured to:
- select a first frequency resource among a plurality of frequency resources;
- perform a first channel access procedure on the first frequency resource;
- transmit, based on the first channel access procedure, a first transmission burst on the first frequency resource after the first frequency resource is determined to be idle and after a random number decrements to 0 based on decrementing the random number by 1 for each slot duration related to the first frequency resource determined to be idle, wherein the random number is randomly obtained among a value included in a contention window;
- perform a second channel access procedure on a second frequency resource among the plurality of frequency resources for a predetermined time duration immediately before the transmission of the first transmission burst, wherein the second frequency resource is different from the first frequency resource;
- and
- transmit, based on the second channel access procedure, a second transmission burst on the second frequency resource after the second frequency resource is determined to be idle for the predetermined time duration.
