    摘要: A circuit (2) and method employing logic circuitry (30) and memory (40) identifies a reverse link limited channel (80). The logic circuitry (30) identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (64). The logic circuitry (30) causes the memory to store reverse link limited channel data (80) in response to the logic circuitry (30) determining that the access probe failure occurred. The reverse link limited channel data (80), for example, may be a channel identification associated with the channel (64), a base station identification associated with the channel (64), a location identification of the circuit (2) or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

    摘要: A method for increase receiver efficiency in a multimode communication device includes a first step of monitoring a received signal strength of a neighboring cell on a receiver channel. A next step includes determining a noise on the receiver channel from a transmitter power amplifier of the communication device. A next step includes comparing the level of interference with a predetermined threshold and with respect to the signal strength. A next step includes blanking the receiver when the transmitter power amplifier of the communication device is on and if the predetermined threshold is not exceeded indicating excessive self-interference.

    摘要: A first sequence state storage module (20) periodically stores a present state (22) of a long code generator (30). Following a restoration of power after a power cut condition, or following the termination of any other interruption of the generation of the long code, a sequence recovery module (50) then provides an updated present state (36). The updated present state (36) is based upon a stored present state (24) and a time value (52) that is reset whenever the present state (22) of the long code or other sequence is stored and that is available even when the long code or other sequence is interrupted.
