Apparatus and method for distinguishing a frame on channel shared by multiple users

摘要

An apparatus and method of distinguishing a frame on a channel shared by a plurality of users. A unique identifier can be obtained for each of a set of mobile communication devices. A message intended for one of the mobile communication devices can be obtained. The message can be scrambled using a long code generated using a mobile communication device specific long code mask to obtain a scrambled message. The unique identifier can be incorporated into the scrambled message for a frame intended for a selected mobile communication device. The frame can then be transmitted. A radio frequency signal can be received for the frame. Demodulation can be performed on the signal to obtain a scrambled signal. A unique identifier can be extracted from the scrambled signal. The unique identifier extracted from the scrambled signal can be examined to determine if the signal is intended for a mobile communication device.
