摘要:
A controller (100) for a wireless communication system determines whether a multiframe control message is imminent, and activates (404, 406) a buffer (112) for storing received frames of a first transmission (202, 204, 206) of the multiframe control message, when the multiframe control message is imminent. The controller receives a retransmission (302, 304, 306) of the multiframe control message, when a received frame of the multiframe control message has an erasure, and reconstructs (500) the multiframe control message from corresponding received frames of both the first transmission and the retransmission.
摘要:
A correlating receiver is used (102) at a code division multiple access base transceiver station to monitor what may comprise possible multi-path versions of a transmission from an authorized communication system user to provide monitoring results. These monitoring results are then used (103) to detect when one of the possible multi-path versions of the transmission was sourced by an unauthorized communication system user while at least another of the possible multi-path versions of the transmission was, in fact, sourced by an authorized communication system user. In a preferred approach the unauthorized communication system user is then identified (104) as being a clone.
