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.
