摘要： In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.

摘要： One or more stations to provide sounding feedback in response to a training signal sequence are determined, and a schedule for the one or more stations to provide sounding feedback is determined based on capabilities of the one or more stations to transmit sounding feedback at a defined time period after an end of the training signal sequence. A communication frame is generated that includes i) an indication of a request for the plurality of stations to provide sounding feedback corresponding to the training signal sequence, and ii) an indication of when the one or more stations are to transmit sounding feedback. The communication frame is transmitted along with the training sequence.
