摘要： In a method for generating a preamble (100) of a data unit for transmission via a multiple input, multiple output (MIMO) communication channel, a first field of the preamble is generated. The first field (VHT-SIG1) provides a plurality of indicators to a plurality of receivers. Each one of the plurality of indicators indicates a set of a plurality of training sequences (VHT-LTF1...N) that corresponds to transmission of the data unit to a corresponding one of the plurality of receivers. The plurality of training sequences is included in a second field of the preamble. The preamble is formatted such that the first field of the preamble will be transmitted prior to the second field of the preamble being transmitted.

摘要： A first communication device transmits a first physical layer protocol data units (PPDU) that includes a first null data packet announcement (NDPA) frame as part of a first ranging measurement exchange. The first communication device transmits a first null data packet (NDP) as part of the first ranging measurement exchange, and records a transmit time of the first NDP. The first communication device determines whether a second NDP was received correctly from a second communication device as part of the first ranging measurement exchange. In response to determining that the second NDP was not received correctly, the first communication device commences a second ranging measurement exchange, including transmitting a second PPDU that includes a second NDPA frame as part of the second ranging measurement exchange.

摘要： A first communication device generates a trigger frame to trigger a contention-based uplink orthogonal frequency multiple access (OFDMA) transmission by multiple second communication devices. The trigger frame may be configured to indicate a predetermined length of the contention-based uplink OFDMA transmission, where the predetermined length corresponds to contention-based uplink OFDMA transmissions. The first communication device transmits the trigger frame to the multiple second communication devices, receives the contention-based uplink OFDMA transmission. The contention-based uplink OFDMA transmission may be of the predetermined length.

A second field of a preamble of a data unit is generated to include a second set of one or more information bits that indicate to a receiver device that conforms to the first (new) communication protocol that the data unit conforms to the first (new) communication protocol. The second field is convolutionally coded using a tail biting technique, and the first field and the second field are modulated using a modulation scheme specified for a field corresponding to the first field and the second field, respectively, by the second (legacy) communication protocol.

摘要： In a method of providing channel state information determined at a second communication device to a first communication device, a channel estimate matrix H describing a forward communication channel between the first communication device and the second communication device is determined at the second communication device (1202). Feedback descriptive of the forward communication channel is determined based on the channel estimate matrix H at the second communication device (1204). When operating in a multi user mode or in a single user mode and with multiple spatial streams, full compressed feedback is generated (1206). Full compressed feedback includes a set of φ angle values and a set of Ψ angle values corresponding to each of one or more columns of the channel estimate matrix. When operating in the single user mode and with a single spatial stream, partial compressed feedback is generated (1208). Partial compressed feedback includes a set of φ angle values, and omits a set of Ψ angle values, corresponding to the channel estimate matrix. The feedback is transmitted from the second communication device to the first communication device (1210).
