摘要： Power consumption is managed in a subscriber station of a communication system. The subscriber station is engaged in a sleep mode, including reducing a frequency of a system clock of the subscriber station. When the subscriber station receives, while in the sleep mode, a message having downlink transmission parameters while, the frequency of the system clock of the subscriber station is increased to process the message. After processing the message, the frequency of the system clock is reduced.

摘要： In a method for generating a preamble of a data unit for transmission via a communication channel, an indication of a first number of spatial or space-time streams is included in a first field of the preamble. The first number of spatial or space-time streams corresponds to transmission of the data unit to a first receiver. One or more training sequences are 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： 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. The information bits are mapped to a constellation symbols. Additionally, either the information bits are encoded according to a block coding scheme, or the constellation symbols are encoded according to the block coding scheme. Orthogonal frequency division multiplexing (OFDM) symbols are generated to include the constellation symbols and the PHY data unit is generated to include the OFDM symbols.

摘要： A first message is received that includes a value indicative of a first timeout interval associated with configuring a second device to operate as a peer-to-peer (P2P) group owner or a P2P client in a P2P wireless network. A second timeout interval is determined based at least on the first timeout interval, and it is determined whether the second timeout interval expired. It is determined whether a second message is received from the second device prior to the second timeout interval expiring, and it is determined that a P2P connection with the second device failed based on a determination that the second message was not received from the second device prior to the second timeout interval expiring.

摘要： A first preamble for a first data unit includes a first long training field and a first signal field modulated according to a first technique. The first data unit is generated according to a first data unit format and includes the first preamble. A second preamble, generated for a second data unit, includes a second signal field and a second long training field. Information in the second signal field is repeated and/or the second long training field is generated so that a duration of the second long training field is longer than a duration of the first long training field.
