摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, first data and second data that correspond to a unit of audio, video, and/or image information is received. The first data and the second data are encoded and modulated so that a resulting data rate of the first data is less than a resulting data rate of the second data. The first data and the second data are parsed to a plurality of spatial streams, and a single PHY data unit that includes the plurality of spatial streams is generated.

摘要： Systems and techniques relating to wireless communications are described. A described technique includes obtaining data for a transmission to a wireless communication device. The wireless communication device can be configured to process incoming transmissions based on an aggregate data unit format that specifies signaling for aggregating multiple medium access control (MAC) data units. The technique includes, in a physical (PHY) frame, an aggregate data unit that is based on the data and the aggregate data unit format, the aggregate data unit including a single MAC data unit. The technique includes, in the PHY frame, an indication to signal that the MAC data unit in the aggregate data unit is singular and to cause the wireless communication device to accept the aggregate data unit without a corresponding block acknowledgement agreement.
