Abstract: A base station sends a synchronization signal in an assigned time slot to a user equipment in a time division duplex code division multiple access communication system. The base station has an assigned code group out of a predetermined number of code groups. The base station transmits selected secondary synchronization code signals out of a set of secondary synchronization code signals. The plurality of secondary synchronization code signals numbers less than half of the predetermined number of code groups. The user equipment identifies the transmitted selected secondary code signals. Based on in part the identified secondary synchronization code signals, the assigned code group is determined.

Abstract: A method for operating a user equipment (UE) employing a CDMA technique, the method comprising: means for combining a plurality of spread spectrum data signals, wherein the output of the combining is a combined signal having a fluctuating power level corresponding to the data signals; means for modulating the combined signal to produce an RF signal for transmission; means for measuring an average power of the output of the combining means for a selected time period; means for adaptively limiting an output of the combined means to a calculated level based at least in part on the measured average power; and means for transmitting the RF signal.

Abstract: A multicellular communications system where transmission between a roving subscriber and multiple base station transceivers is maintained throughout the territory. Each mobile subscriber unit has global code seeds for the entire communications system or an updated neighbor list and continuously searches to access available cell base stations while maintaining a communication link with one base station. Candidate cell base stations are interrogated and communicated with. The candidate base station that requires less transmitting energy from the mobile subscriber unit is closely monitored. When the mobile subscriber unit can successfully communicate with less transmit power than currently required by the present base station, the mobile subscriber unit is handed off to the candidate base station transceiver.

Abstract: A transmission is simultaneously provided on multiple mesh networks. Retransmission between two nodes may be performed for the same communication along multiple networks in a mesh topography for the multiple networks. This permits communication to be effected in a mesh topography where one or all systems would not be able to provide a complete network connection within any given system.
