    Abstract: One aspect of the disclosure provides a method for wireless communication. The method includes sending a modulation and coding scheme request to an access point. The modulation and coding scheme request is sent using a first physical layer preamble frame. The modulation and coding scheme request includes an identifier associated with the access point. The method further includes receiving at a station a modulation and coding scheme feedback response from the access point in response to sending the modulation and coding scheme request. The modulation and coding scheme feedback response is received as a second physical layer preamble frame. In addition, the method includes determining a modulation and coding scheme based on the modulation and coding scheme feedback response. Moreover, the method includes transmitting data to the access point using the identified modulation and coding scheme.

    Abstract: Transmission parameters are determined for communication between apparatuses. These transmission parameters may specify, for example, a number of spatial streams, a bandwidth, and a transmission rate. Based on the determined parameters, a table of a set of tables comprising transmission parameters is identified and an index from the table is determined. Rate information is then sent in a frame from one of the apparatuses to the other. The rate information comprises several fields indicative of the index, the number of spatial streams, and bandwidth. The apparatus that receives the rate information may then use this information to identify the table and obtain transmission parameters from the table.

    Abstract: Techniques for signaling extended sizes for Medium Access Control (MAC) Protocol Data Unit (MPDU), Aggregated MPDU (A-MPDU) and Aggregated MAC Service Data Unit (A-MSDU) frame formats. A first technique proposes modifications to the current specifications of the IEEE 802.11η standard in order to allow for longer MPDUs in an A-MPDU. This technique reuses the IEEE 802.11η signaling format and utilizes reserved bits to convey the new information, i.e. an indication that the maximum length of a MAC RDU, MPDU frame, of an A-MRDU, or ofan A-MSDU is respectively greater than 4095 bytes. 64 kilobytes and 7935 bytes. The second technique proposes a new signaling mechanism to convey the extended sizes for the MPDU, A-MPDU and the A-MSDU through a very high throughput (VHT) capability element. One or more bits may be added to the delimiter field.

    Abstract: Simultaneous, multi-user uplink communication is scheduled in a wireless network (100) by transmitting a poll message (411) to a plurality of access terminals (403-406) in response to receiving a first request to transmit data (410) via uplink. The poll message (411) includes a solicitation for requests to transmit data from each of the plurality of access terminals (403-406). The poll message (411) also includes a medium reservation and schedule for transmission of the requests from the access terminals. Based on the requests received from the access terminals, a number of the access terminals (403, 404) are selected for simultaneous transmission of data (418, 419) via uplink. A transmit start message (416) is sent to each of the selected access terminals (403, 404) indicating when and for how long the selected access terminals (403, 404) may transmit data via uplink. After the data (418, 419) is received, a block ACK message (422, 423) is sent to each of the selected access terminals (418, 419) indicating successful simultaneous communication.
