Abstract
A method and system for wireless communication in an asymmetric antenna system (AAS) communication system is provided. A wireless station performs carrier sensing by sensing a wireless communication channel for ongoing communications in one or more directions. Upon detecting that the wireless communication channel is idle, the station transmits a frame preamble on the channel to a receiving wireless station in more than one transmit direction, and transmits a frame payload on the channel to the receiving wireless station in one transmit direction.
