摘要： An access point including a transceiver having first and second physical layers to communicate at first and second data rates, respectively. The transceiver receives a request from a first client station to reserve first or second sub-channel of a channel for transmitting data at the first or second data rate. In response to receiving the request from the first client station, the transceiver transmits a response to allow the first client station to transmit data and prevent a second client station from transmitting data while the first client station transmits data to the access point. In response to the first client station receiving the response, the first physical layer receives data from the first client station without interference from the second client station.

摘要： A preamble, a first portion of a data payload, a midamble, and a second portion of the data payload of a single data unit are generated. The midamble is to be transmitted subsequent to transmission of the first portion of the data payload and prior to transmission of the second portion of the data payload. The midamble includes an indication of at least one characteristic of the data payload such as an indication of a size of the second portion of the data payload, or whether or not the data payload includes one or more other portions in addition to the first and second portions. A network interface of a communication device is configured to generate the preamble, the first and second portions of the data payload, and the midamble.

摘要： In a method implemented in a communication device configured to transmit PHY data units via a communication channel, first data and second data is received. The first data is modulated according to a first constellation having a first number of constellation points, and the second data is modulated according to a second constellation having a second number of constellation points higher than the first number of constellation points. The first data and the second data is parsed to a plurality of spatial streams such that a first subset of the spatial streams includes at least some of the modulated first data but none of the modulated second data, and a second subset of the spatial streams includes at least some of the modulated second data but none of the modulated first data. A single PHY data unit that includes the plurality of spatial streams is generated.

摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are encoded using a forward error correction (FEC) encoder. Also, the information bits are encoded according to a block coding scheme, where m copies of each bit are included in the information bits, and one or more bits in the m copies of each bit are flipped. The information bits are mapped to a plurality of constellation symbols, and a plurality of orthogonal frequency division multiplexing (OFDM) symbols are generated to include the plurality of constellation symbols. The PHY data unit is generated to include the plurality of OFDM symbols.

摘要： Embodiments of the present invention provide a method that includes receiving, by a traffic arbiter, a predetermined time-slot allocation of one or more uplink time slots and/or one or more downlink time slots for a first wireless media access control (MAC) configured to operate within a first wireless transmission system. The method also includes determining, by the traffic arbiter, whether to grant a second wireless MAC, configured to operate within a second wireless transmission system, permission to transmit or receive based at least in part on the predetermined time-slot allocation.

摘要： A communication device generates a physical layer (PHY) data unit that includes a PHY preamble and one or more PHY midambles. The communication generates the PHY preamble of the PHY data unit to include i) a signal field having a subfield that indicates that the PHY data unit includes one or more PHY midambles, ii) a short training field (STF) for automatic gain control (AGC) training and synchronization at a receiver, and iii) one or more long training fields (LTFs) for determining a channel estimate at the receiver. The communication generates a data payload of the PHY data unit having i) a set of orthogonal frequency division multiplexing (OFDM) symbols, and ii) one or more PHY midambles. Each of the one or more PHY midambles includes one or more LTFs for determining an updated channel estimate. The communication device transmits the PHY data unit via a wireless communication channel.

摘要： A desired number of buffers to be used in a block acknowledgment (BA) session or with media access control (MAC) data units having a same traffic identifier (TID) is determined. A desired maximum MAC data unit size to be used in the BA session or with the MAC data units having the same TID is determined. An indication of the desired number of buffers in the BA session or with the MAC data units having the same TID is transmitted to a communication device in a wireless communication network for negotiating with the communication device. An indication of the desired maximum MAC data unit size to be used in the BA session or with the MAC data units having the same TID is transmitted to the second communication device for negotiating with the other station.
