    Abstract: A variable gain receiver responds to a gain control signal. A controller is coupled to the receiver and monitors received signal quality and power level. The controller generates a signal as a function of the received signal quality and power. The receiver controls gain as a function of power and selectively controls gain as a function of quality. An independent claim is also given for a method for providing allocating channels to remote transceivers.

    Abstract: A method and apparatus for cell reselection during transmission of data between a mobile station and a network through a first cell of a plurality of cells, each of the plurality of cells defining a corresponding radio coverage area. A control stack ( 305 ) organizes the data within frames during the transmission of data, and an adjustment module ( 324 ) adjusts a size of the frames prior to detection that a second cell of the plurality of cells is a candidate for reselection.

    Abstract: A simplified version of a defined GPRS/EDGE Class A mobile station (202) that incorporates transmission and reception of GPRS/EDGE data during discontinuous transmission and reception modes on a dedicated traffic channel (204), and that includes a mechanism for streaming GPRS/EDGE data to and from a packet-switched channel, along with optional association of a voice time slot with one or more GPRS/EDGE data time slots. GPRS/EDGE packet data and circuit-switched voice data are simultaneously transmitting along a dedicated GSM voice traffic channel (204) by transmitting the GPRS/EDGE packet data (212) between occurences of circuit-switched voice data (208) and silence descriptor frame data (210) along a dedicated voice traffic channel (204).

    Abstract: A mobile phone AGC controller monitors the received signal power and the receiver bit error rate. When the received signal quality is lower than optimal, the AGC controller tracks the value of the BCCH carrier. As the mobile phone approaches the base station, the received signal quality and the carrier level become sufficient to permit transmitter power reduction at the base station, thus minimizing interference and maximizing cell occupancy. Additional gain reduction may be applied in the receiver when the mobile phone is close to the base station. In particular, if the ratio of the carrier signal power to the bit error rate exceeds an optimum level, then the receiver gain may be reduced. Channels may be allocated dynamically so that mobile phones having a common distance from the base station are on a common channel (figure 11).
