Abstract:
The present invention relates to a wireless communication system, and more specifically, a method and a device for the scanning of a station (STA) in a WLAN system are disclosed. The whereby an STA performs scanning in a wireless communication system according to one embodiment of the present invention comprises the steps of: transmitting a first frame, including a BSSID-AP CCC pair, to one or more access points (AP); and receiving a second frame from an AP among the one or more ALs, wherein the system information of the AP, which is included in the second frame, includes dynamic information and can configure the second frame to be optimized according to the dynamic information.
Abstract:
Disclosed is a method for transmitting a signal of an access point (AP), comprising the steps of receiving a first frame from a first STA; and transmitting a second frame including a response to the first frame to the first STA, wherein the second frame induces the transmission of a third frame for the first STA to make the second STA set a network allocation vector (NAV), and the second STA is an STA unable to sense the AP.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for updating system information in a wireless LAN system. A method for a station (STA) to update system information in a wireless communication system according to one embodiment of the present invention comprises the steps of: if the value of a change sequence field received by the STA from an access point (AP) is different from the value of the change sequence field stored in the STA, transmitting, to the AP, a probe request frame including the change sequence field set to the value of the change sequence field stored in the STA; and a step of receiving, from the AP, a probe response frame responding to the probe request frame including the change sequence field.
Abstract:
The present invention relates to a wireless communication system, and more particularly, to a method and device for performing or supporting selective decoding of a beacon frame in a wireless LAN system. A method of decoding a frame by a station STA in a wireless communication system according to an embodiment of the present invention may include: determining whether to decode each of a first data portion and a second data portion of the frame; and decoding one or more of the first data portion and the second data portion if it is determined that the decoding is performed. Hence, the frame may further include information that is used for the determination by the station STA on whether to decode each of the first data portion and the second data portion, and whether to decode may be determined on the basis of whether to change one or more of the first data portion and the second data portion.
Abstract:
Disclosed are a method and an apparatus for updating a listen interval in a wireless communication system. To this end, a method for updating a listen interval by a station (STA) of a wireless communication system may comprise, if an operation mode of the station is changed, a request frame including information indicating that the operation mode of the station is changed, to an access point (AP); and receiving a response frame in response to the request frame from the AP. If a value of a listen interval of the station is changed as the operation mode of the station is changed, the request frame further include a value of a new listen interval of the station.
Abstract:
One embodiment of the present invention relates to a method whereby a station (STA) which is irrelevant to a multi user (MU) group performs channel access in a wireless communication system, the method for performing channel access comprising the steps of: receiving a resource allocation frame; and checking a group indicator field comprised in the resource allocation frame, wherein the STA determines a slot start offset through the first bit of a slot allocation field for the MU group in case the group indicator field indicates the presence of the slot allocation field for the MU group in the resource allocation frame.

A method for a station (STA) to update system information in a wireless communication system according to one embodiment of the present invention comprises the steps of: if the value of a change sequence field received by the STA from an access point (AP) is different from the value of the change sequence field stored in the STA, transmitting, to the AP, a probe request frame including the change sequence field set to the value of the change sequence field stored in the STA; and a step of receiving, from the AP, a probe response frame responding to the probe request frame including the change sequence field.
Abstract:
The present invention relates to a wireless communication system, and more specifically, to a method for setting up a high-speed link in a WLAN system and a device for the same. A method for setting up a high-speed link by a station (STA) in a WLAN system, according to one embodiment of the present invention, can comprise the steps of: transmitting a frame including identification information and/or fragment identification information of a previous access point (AP) from the STA to a current AP; and receiving Generic Advertisement Service (GAS) query response information from the current AP, wherein when the identification information of the previous AP is included in the frame, the GAS query response information can be acquired by the current AP from the previous AP.
Abstract:
One embodiment of the present invention relates to a method for transmitting a signal of a station (STA) operable in a power saving mode in a wireless communication system, and the method for transmitting a signal comprises a step of transmitting a PS-Poll frame and/or a trigger frame according to a first time period, wherein an integrated scaling factor is applied to the first time period, and the integrated scaling factor is also commonly applied to a second time period in which the STA can omit frame transmission by maintaining an association state with an access point (AP).
Abstract:
The present invention relates to a method for transmitting and receiving a traffic indication map in a wireless communication system, and to an apparatus for same. More particularly, the method includes a step of transmitting a traffic indication map (TIM) to a station (STA) through a beacon frame, wherein the TIM can include a bitmap field configured of one or more sub-block bitmaps for indicating whether buffered downlink data exists for an STA which is grouped to one or more sub-blocks, and a block control field indicating an encoding scheme of the bitmap field.
