摘要： In a method for generating a preamble 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 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 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： Systems and methods for service period recovery in a wireless communications system are provided. An initial service period for transmitting data is assigned to a first remote station. Data period schedule information, including the assignment of the initial service period, is transmitted from a central station. In response to determining that the first remote station is not transmitting during the initial service period, a modified service period is assigned to the first remote station. A service period change announcement, including the assignment of the modified service period, is transmitted from the central station. In response to determining that the first remote station is not transmitting during the modified service period, the initial service period is truncated and a service period truncation is transmitted from the central station.

摘要： A method of generating packets for transmission in a wireless communication system, wherein each packet includes a SIG field that includes a first SIG subfield, includes generating a data packet and a null data packet. Generating the data packet includes generating information bits of the first SIG subfield of the data packet and generating the data portion of the data packet. The information bits of the first SIG subfield of the data packet indicate, to a receiving device, a length corresponding to a data portion of the data packet. Generating the null data packet includes generating information bits of the first SIG subfield of the null data packet. The information bits of the first SIG subfield of the null data packet indicate, to a receiving device, a first physical layer (PHY) parameter value associated with the null data packet. The first PHY parameter value is not a length value.
