Abstract: 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.

Abstract: A wireless local area network (WLAN) device processes received samples for a radio frequency channel in an unlicensed radio frequency band to detect radio frequency interference from a long term evolution (LTE) wireless communication system. The WLAN device performs a correlation of received time-domain samples to detect the presence of a cyclic prefix for an orthogonal frequency division multiplexing (OFDM) symbol used by the LTE wireless communication system. The WLAN device searches for cross-correlation peaks (1) that exceed a peak power threshold value, (2) that a ratio of which exceed a ratio threshold, and (3) that are separated by a time period corresponding to the OFDM symbol. The WLAN device detects the presence of the LTE wireless communication system without decoding the OFDM symbols.

The access point supports connections to client devices using a “legacy” mode over a single logical channel mapped to a single RF channel and includes data traffic, control traffic, and management frames combined. The access point also supports connections to client devices using a high efficiency WLAN mode having multiple logical channels, each logical channel associated with one or more physical RF channels. The multiple logical channels include a management channel for management frames and a separate high efficiency WLAN data channel to carry data traffic and control traffic.
