控制WLAN的数据单元格式

Control data unit format for WLAN
Abstract:
In a method for generating a control data unit a physical layer (PHY) preamble of the control data unit is generated. In generating the PHY preamble, an address field is generated to indicate a communication device for which the data unit is intended, and a frame type field is generated to indicate a type of the control data unit. The address field and the frame type field are included in the PHY preamble. The control data unit is generated to include the PHY preamble. The control data unit is transmitted. The control data unit omits (i) a MAC header, and (iii) a payload.
