System and method embodiments are provided for transmitting a packet to a wireless device using a partial identifier. The embodiments enable communication using partial addresses with reduced risk of collision between two devices that share the same partial identifier. In an embodiment, a method includes determining at the first wireless station a scrambled identifier for a second wireless station according to a synchronized time and a partial identifier corresponding to one of the first wireless station and the second wireless station, wherein the synchronized time is synchronized with a time in the second wireless station, and wherein the partial identifier comprises a portion of a device identifier for at least one of the first wireless station and the second wireless station, and transmitting a packet to the second wireless station, wherein the packet comprises a payload and a header, and wherein the header comprises the scrambled identifier.
