    Abstract: The present disclosure provides a wireless communication method. The wireless communication method includes a first device used to negotiate a buffer size with a second device, provide data including a duration field to the second device, and receive a first block acknowledgement from the second device. The first block acknowledgement may include a first block acknowledgement bitmap. The duration field included in the data from the first device may include an indication of a duration associated with the first block acknowledgment that is less than an upper bound duration associated with a second block acknowledgement that includes a second block acknowledgement bitmap with a maximum length.

    Abstract: A beamformee device includes a channel estimator, first and second beamforming matrix providers and a dimension reduction unit. The channel estimator receives a NDP through a channel, and obtains channel information of the channel based on the NDP. The first beamforming matrix provider provides wideband beamforming matrices based on the channel information. The dimension reduction unit generates equivalent channel information based on the wideband beamforming matrices. The second beamforming matrix provider provides beamforming matrices based on the equivalent channel information. The wideband beamforming matrices and the subcarrier beamforming matrices are fed back to the beamformer device. Any one or any combination of the plurality of wideband beamforming matrices and the plurality of subcarrier beamforming matrices are selected from codebooks.

    Abstract: A method for a first device to communicate with at least one second device in a wireless local area network (WLAN) system includes providing a first trigger frame to at least one second device, the first trigger frame requesting at least one sounding null data packet (NDP), providing a feedback frame to the at least one second device, the feedback frame including feedback information generated based on the at least one sounding NDP, and providing a second trigger frame to the at least one second device, the second trigger frame requesting at least one beamformed physical layer protocol data unit (PPDU), each of the first trigger frame and the feedback frame including a sounding dialog token number field having a sounding sequence number.

    CPC classification number: H04L69/08 ,  H04L69/18 ,  H04L2212/00 ,  H04W84/12

    Abstract: A method of communicating between a first device (e.g., an AP) and each of with a legacy device and a non-legacy device (e.g., STAs) includes, at the first device, generating a first information field for the legacy device, generating a second information field for the non-legacy device, generating a frame including the first information field and the second information field, and transmitting the frame, wherein the first information field includes a first value by which the legacy device identifies the first information field as valid, wherein the second information field includes a second value by which the legacy device identifies the second information field as invalid.
