    摘要： A method of transmitting data by a multi-user multiple input multiple output (MU-MIMO) transmitter in a wireless local area network system. The method according to one embodiment includes generating a physical layer convergence procedure (PLCP) protocol data unit (PPDU), the PPDU including a bundled interface field, a modulation and coding scheme (MCS) index field and a data field; and transmitting the PPDU to a plurality of receiving stations. The bundled interface field indicates a number of one or more spatial streams allocated to the plurality of receiving stations. The MCS index field indicates a same MCS index used for modulating and coding all of the one or more spatial streams indicated by the bundled interface field. The data field is modulated and coded by an MCS scheme indicated by the MCS index field and transmitted via the one or more spatial streams indicated by the bundled interface field.

    摘要： A method and an apparatus for protecting a primary service as an unlicensed device in a regulatory domain where a licensed device and the unlicensed device are permitted to operate are disclosed. For protecting a primary service by a station as an unlicensed device in a regulatory domain where a licensed device and the unlicensed device are permitted to operate, the unlicensed device acquires a list of identified available channels for the operation of the unlicensed device and maximum allowed transmission powers of the identified available channels from a regulatory domain database system; generates a white space map (WSM) comprising the list of identified available channels and the maximum allowed transmission powers of the identified available channels; updates the WSM when the station acquires information that a primary service signal is detected on a specific channel which is indicated as available in the WSM; and transmits the updated WSM to another station such that the another station moves to another channel if the another station is operating on the specific channel.

    摘要： A method and an apparatus for scanning existing networks in TV White Space are disclosed. For scanning existing networks at a station to operate as an unlicensed device in a regulatory domain where a licensed device and the unlicensed device are permitted to operate, the method comprises: receiving a white space map (WSM) comprising information for available channels to be used for the unlicensed device to operate a wireless local area network (WLAN) operation and maximum transmission powers allowed for each of the available channels from an enabling station, wherein the enabling station is a station determining the available channels at its location using its own geographic location identification and a regulatory database access capability; and scanning the existing networks on the available channels identified within the received WSM.

    摘要： A method, performed by a transceiver, is described. The transceiver receives a null data packet announcement (NDPA) frame to initiate channel sounding and a null data packet (NDP), the NDP following the NDPA frame. A first report field including beamforming information and a second report field including signal to noise ratio (SNR) information is configured. First feedback data including the first report field and a second report field is split into a plurality of segments. The plurality of segments is transmitted in a single aggregated medium access control protocol data unit (A-MPDU) including MPDUs. A retransmission request including a segment retransmission bitmap field indicating at least one segment of the plurality of segments for retransmission is received. In response to the retransmission request, second feedback data including the at least one segment indicated by the segment retransmission bitmap field is transmitted.

    摘要： A channel access method for a very high throughput (VHT) system using a bonding channel having a plurality of subchannels is provided. The method includes receiving training information comprising a training offset value through a subchannel, performing channel estimation on a full channel bandwidth comprising all subchannels when a time corresponding to the training offset value is elapsed after the training information is received, transmitting a request to send (RTS) frame to a destination station through some subchannels selected from the plurality of subchannels by one or a plurality of source stations according to a result of the channel estimation, and transmitting a clear to send (CTS) frame to one source station selected from the plurality of source stations by the destination station in response to the received RTS frame. Accordingly, an effective channel access mechanism is provided for the VHT system, and collision among stations can be avoided.
