摘要： A wireless station includes a transceiver configured to wirelessly receive networking frames over a wireless medium, and a channel access counter configured to track a time period and signal that the time period has expired. The time period begins in response to a first networking frame of the networking frames. The first networking frame is addressed to a receiver other than the wireless station. A length of the time period is based on a first length in response to a type of the first networking frame being an acknowledgment frame type. The length of the time period is based on a second length in response to the type of the first networking frame being a data frame type. The transceiver is configured to wait to access the wireless medium until after the channel access counter signals that the time period has expired.

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.
