Abstract
Provided is a method and apparatus for allocating resources in a wireless local area network (WLAN) system, the method including determining a restricted access bandwidth (RAB) interval based on at least a bandwidth or a partial bandwidth among a plurality of bandwidths, and setting a restricted access window (RAW) of a time domain based on the RAB interval.
Claims21
A resource allocation method by an access point (AP) in a wireless local area network (WLAN) system, the method comprising:
- determining a restricted access bandwidth (RAB) information indicating a set of channels of frequency domain;
- setting a restricted access window (RAW) information indicating a time duration of a time domain;
- and
- transmitting the RAB information and the RAW information to at least one station (STA),
- wherein, based on the RAB information, a first subset of channels are allowed to a first STA, and a second subset of channels are allowed to a second STA,
- wherein, based on the RAW information, a first time duration is allowed to the first STA to access the first subset of channels, and a second time duration is allowed to the second STA to access the second subset of channels, and
- wherein the first time duration does not overlap with the second time duration.
A communication method in a wireless local area network (WLAN) system, the method comprising:
- receiving, by a first station (STA), restricted access bandwidth (RAB) information indicating a set of channels of a frequency domain and restricted access window (RAW) information indicating a time duration of a time domain;
- transmitting or receiving, by the first STA, data based on the RAB information and the RAW information,
- wherein, based on the RAB information, a first subset of channels are allowed to the first STA, and a second subset of channels are allowed to a second STA,
- wherein, based on the RAW information, a first time duration is allowed to the first STA to access the first subset of channels, and a second time duration is allowed to the second STA to access the second subset of channels, and
- wherein the first time duration does not overlap with the second time duration.
A resource allocation apparatus for an access point (AP), the apparatus comprising:
- a restricted access bandwidth (RAB) interval determiner to determine RAB information indicating a set of channels of a frequency domain;
- a restricted access window (RAW) setting unit to set RAW information indicating a time duration of a time domain;
- and
- a communicator to transmit, to at least one station (STA), the RAB information and the RAW information,
- wherein, based on the RAB information, a first subset of channels are allowed to a first STA, and a second subset of channels are allowed to a second STA,
- wherein, based on the RAW information, a first time duration is allowed to the first STA to access the first subset of channels, and a second time duration is allowed to the second STA to access the second subset of channels, and
- wherein the first time duration does not overlap with the second time duration.
