A method of processing signals received from an electronic device () in a cellular network () that utilizes variable rate vocoding comprising receiving a first series of low rate frames () at the cellular network; receiving a high rate frame () that has at least one bit error at the cellular network after receiving the first series of low rate frames, wherein the rate of the high rate frame can be determined; and sending a request () to the electronic device to retransmit the high rate frame.

Method and apparatus for full rate erasure handling in CDMA

An apparatus and method for processing a corrupted frame. The corrupted frame is analyzed to ascertain whether the rate can be determined. If the rate can be determined, steps for identifying the rate are executed. After the rate is identified, the method scans the corrupted frame by checking the MM/TT/TM or MM/FM bits (depending on the radio configuration) to determine whether signaling is present in the frame. If the scan finds potential signaling information, the BTS informs the transcoder of the frame rate, that signaling is present in the frame and that the outer CRC failed. The transcoder attempts to recover the signaling information based upon the inner CRC and discards the bearer information. If the signaling message is spread over multiple frames, the entire frame is discarded to avoid confusion when the signaling message has to be reassembled. The entire frame is also discarded if the inner CRC fails.

Apparatus and method for processing a corrupted frame

Selective reverse mobile frame biasing is provided for improved network control between a mobile unit ( ) and a base station ( ) responsive to power control bits from the base station. Signaling messages ( ) received at the base station ( ) are monitored to identify signaling messages requiring the mobile unit to send a response containing a critical signaling message. The base station ( ) informs the mobile unit ( ) to send the response containing the critical signaling message with an increased power bias for the duration of the message. Transmission power of the mobile unit ( ) is allowed to decay after the critical signaling message is sent.

Network control having selective reverse mobile frame biasing

Receivers (,) within a base station (,) receive a transmission from a remote unit (,). The received signal is delayed a first amount by first delay circuitry (,), and a second amount by second delay circuitry (,). During despreading, a delayed input signal is despread with a Pseudo-Random (PN) code. The system time utilized by the PN generators (,) is delayed a third time period by third and fourth delaying circuitry (,).
