Method for allocating resources in wireless LAN system and wireless LAN system
Provided are a method of allocating resources in a wireless local area network (WLAN) system and the WLAN system including an access point (AP) to allocate a resource for communication between a relay and a station associated with the relay, the relay to allocate a restricted access window (RAW) or a slot for communication with a station based on the allocated resource, and the station to communicate with the relay based on the allocated RAW or the allocated slot.
1. A method for an access point (AP) in a wireless local area network, the method comprising:
generating restricted access window (RAW) parameters including information on a first type RAW, and
transmitting the RAW parameters to at least one station,
wherein the information on the first type RAW includes resource allocation information for a frequency domain,
wherein the resource allocation information for the frequency domain is selectively included in the information on the first type RAW, and
wherein a station indicated by the RAW parameters is allowed to transmit data using at least one channel of the first type RAW based on the resource allocation information for the frequency domain.
2. The method of claim 1 , wherein the at least one channel is frequency subbands for the communication between the AP and the station indicated by the RAW parameter.
3. The method of claim 1 , wherein the RAW parameters includes information on a second type RAW indicating that an access point (AP) neither transmits to nor receives from stations associated with the AP regardless of a type of station within a duration of the second type RAW.
4. The method of claim 1 , wherein the information on the first type RAW includes resource allocation information for a time domain.
5. The method of claim 4 , wherein a station indicated by the RAW parameters is allowed to transmit data within a duration of the first type RAW based on the resource allocation information for the time domain.
6. An access point (AP) apparatus in a wireless local area network, the AP apparatus comprising:
a controller; and
a communication unit,
wherein the controller is configured to:
generate restricted access window (RAW) parameters including information on a first type RAW,
transmit the RAW parameters to at least one station,
wherein the information on the first type RAW includes resource allocation information for a frequency domain,
wherein the resource allocation information for the frequency domain is selectively included in the information on the first type RAW, and
wherein a station indicated by the RAW parameters is allowed to transmit data using at least one channel of the first type RAW based on the resource allocation information for the frequency domain.
7. The AP of claim 6 , wherein the at least one channel is frequency subbands for the communication between the AP and the station indicated by the RAW parameter.
8. The AP of claim 6 , wherein the RAW parameters includes information on a second type RAW indicating that an access point (AP) neither transmits to nor receives from stations associated with the AP regardless of a type of station within a duration of the second type RAW.
9. The AP of claim 6 , wherein the information on the first type RAW includes resource allocation information for a time domain.
10. The AP of claim 9 , wherein a station indicated by the RAW parameters is allowed to transmit data within a duration of the first type RAW based on the resource allocation information for the time domain.
11. A method for a station in a wireless local area network, the method comprising:
receiving restricted access window (RAW) parameters including information on a first type RAW, and
performing channel access based on the RAW parameters,
wherein the information on the first type RAW includes resource allocation information for a frequency domain,
wherein the resource allocation information for the frequency domain is selectively included in the information on the first type RAW, and
wherein a station indicated by the RAW parameters is allowed to transmit data using at least one channel of the first type RAW based on the resource allocation information for the frequency domain.
12. The method of claim 11 , wherein the at least one channel is frequency subbands for the communication between the AP and the station indicated by the RAW parameter.
13. The method of claim 11 , wherein the RAW parameters includes information on a second type RAW indicating that an access point (AP) neither transmits to nor receives from stations associated with the AP regardless of a type of station within a duration of the second type RAW.
14. The method of claim 11 , wherein the information on the first type RAW includes resource allocation information for a time domain.
15. The method of claim 14 , wherein a station indicated by the RAW parameters is allowed to transmit data within a duration of the first type RAW based on the resource allocation information for the time domain.
