摘要： A method and apparatus for transmitting and receiving a frame including a partial association ID (PAID) in a wireless LAN (WLAN) system are disclosed. A method for receiving a frame at a station (STA) from an access point (AP) of a wireless communication system including: determining whether a value of a partial association ID (Partial AID) of the frame is calculated on the basis of an association ID (AID) allocated to the STA by the AP and a basic service set ID (BSSID) of the AP; and decoding the frame, if the value of the partial AID of the frame is calculated on the basis of the AID allocated to the STA and the BSSID of the AP, wherein the AID is allocated such that the partial AID value calculated on the basis of the AID allocated to the STA and the BSSID of the AP is not identical to a first PAID value calculated by applying a modulo operation to a specific value obtained by converting values ranging from a 40th bit position to a 48th bit position from among 48 bit positions of the BSSID of the AP into a decimal number.

摘要： The present invention relates to a method and a device for updating system information in a wireless LAN system. A method for updating system information in a station (STA) of a wireless communication system may comprise transmitting, by the STA which stores system information and a configuration change count value of a previously linked preferred access point (AP), a probe request frame for active scanning to the preferred AP; and receiving a probe response frame from the preferred AP. Preferably, the probe request frame includes a configuration change count field previously acquired from the preferred AP, and if a value of the configuration change count field included in the probe request frame is different from a present configuration change count value of the preferred AP, the probe response frame may include one or more elements of system information which should be updated by the STA.

摘要： The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for accessing a channel in a wireless LAN system. According to one embodiment of the present invention, a method for performing channel access by a station (STA) of a wireless communication system comprises: a step of receiving, from an access point (AP), information about the time window which does not allow channel access of a traffic indication map (TIM) mode STA; and a step of performing channel access based on the time window. In the event that the STA is a non-TIM mode STA, the channel access is performed in the time window. In the event that the STA is a TIM mode STA, the channel access is performed in the time interval indicated by the TIM, excluding the time window.
