    Abstract: A method of transmitting basic service set (BSS) load information. The method according to one embodiment includes establishing, by an access point (AP), an association with at least one very high throughput (VHT) station that has successfully synchronized with the AP and that has a capability of receiving at least one spatial stream of a plurality of spatial streams transmitted via a multi user-multiple input multiple output (MU-MIMO) transmission; and broadcasting, by the AP, a beacon frame that includes load information including a station count field and an antenna utilization field. The station count field indicates a number of the at least one VHT station that has successfully synchronized with the AP and that has the capability of receiving at least one spatial stream of the plurality of spatial streams. The antenna utilization field indicates information about spatial streams that are under-utilized in the MU-MIMO transmission.

    Abstract: A communication method that includes transmitting a power save multi-poll (PSMP) frame containing a power save mode (PSM) of a non-access point (AP) station (STA) to a first station and to a second station which are paired with an AP on the basis of multiple input multiple output (MIMO) technology. Information on the PSM indicates the point in time of starting a downlink transmission period, the duration of the downlink transmission period, and transmission object station identification information. The method further involves transmitting a data frame to the first station and to the second station on the basis of the MIMO technology during the downlink transmission period. The transmission object station identification information indicates a group identifier for indicating an object station group including the first station and the second station.

    Abstract: Provided is a communication method by a station (STA) that operates in a power safe mode in a wireless LAN system. The method comprises: transmitting a probe request frame to an access point (AP), wherein the probe request frame includes system information identification information for identifying system information acquired by the STA; and receiving a probe response frame as a response to the probe request frame from the AP. The probe response frame includes a time stamp value related to the point of time of transmitting the probe response frame, and if it is determined, based on the system information identification information, that updated information which is not included in said acquired system information exists, the probe response frame further includes said updated information. Also provided is a communication method by an access point (AP) in a wireless LAN system. The method comprises: receiving a probe request frame from a station (STA), wherein the probe request frame includes information related to a wake-up duration time that is a time period in which the STA operates in an awake state; and transmitting a probe response frame to the STA as a response to the probe request frame. The probe response frame is transmitted within said wake-up duration time.

    Abstract: A method for a channel sounding in a wireless local area network. A station receives a 20 MHz null data packet announcement (NDPA) frame and at least one duplicate 20 MHz NDPA frame. The at least one duplicate 20 MHz NDPA frame is a duplicate of the 20 MHz NDPA frame. The station also receives a null data packet (NDP) following the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame. The bandwidth over which the 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame are transmitted is the same as a bandwidth over which the NDP is transmitted. The station transmits a report frame for the channel sounding. The 20 MHz NDPA frame and the at least one duplicate 20 MHz NDPA frame comprise bandwidth information indicating the bandwidth over which the frames are transmitted.
