摘要： A method of scaling soft symbols of an uplink E-DCH is provided, where the E-DCH is received from a user in a network for processing in a base station receiver in the network employing a log-MAP turbo decoding algorithm to process the E-DCH. The E-DCH includes an E-DPDCH from which the soft symbols are generated at the base station receiver, and an E-DPCCH used to transmit control information associated with the E-DPDCH, which along with configuration information from a radio network controller (RNC) of the network enables the base station receiver to determine a reference amplitude ratio linked to the actual power offset of the E-DPDCH from the legacy DPCCH. In the method, a reference E-DPDCH to DPCCH amplitude ratio is multiplied by a value greater than 1 to output a scaling factor, and the soft symbols are scaled by the scaling factor for processing by the log-MAP turbo decoding algorithm in the base station receiver.

摘要： The need for separate CRC bits is eliminated by taking advantage of what has been determined to be an embedded error detection capability of the tail bits generated by the constituent encoders of a turbo coder to perform error detection following turbo decoding. Specifically, it has been recognized that the tail bits are similar to CRC bits that would be generated by a CRC encoder that uses as its generating polynomial the feedback polynomial used by the turbo encoder. At the turbo decoder, after a final turbo decoding iteration cycle, a check is performed on the decoded systematic information bits by calculating the tail bits from the decoded information bits using that generating polynomial and bit-by-bit comparing the calculated tail bits with the systematic tail bits decoded by the turbo decoder. If a mismatch occurs at one or more bit positions, an error is indicated.

摘要： The channel quality indicator (CQI) transmitted by a mobile terminal to a base station is indicative of the Ec/Nt pilot SNR of the pilot signal transmitted by the base station and measured by the mobile terminal. The base station uses the CQI for purposes such as determining a downlink rate, a modulation scheme, and downlink power. Knowledge by the base station of whether the received and detected CQI is likely to be “good” or “bad” would be useful in determining how and whether the value of the received and detected CQI should be used. In a first embodiment, at the base station, a reliability of the received CQI that is detected from received soft symbol metrics is determined in conjunction with the detected CQI value for the received CQI word as a whole. In a second embodiment, a minimum bit error probability receiver is used that makes a maximum likelihood decision for each CQI bit individually from the plurality of metrics derived from the received soft symbol metrics, and the reliability of each CQI bit is individually determined.

摘要： In the absence of a continuous channel from the mobile terminal that incorporates a CRC in each transmitted frame from which the base station can derive a power control signal for feedback to the mobile station for maintaining the mobile station's pilot Eb/N0 level at a desired target that corresponds to a particular frame error rate, the pilot signal received by the base station from the mobile terminal itself is arranged in a frame format. Each pilot frame is compared with an a prioi known transmitted pilot signal bit pattern to determine whether it has been received in error. In response to a comparison of a received pilot frame with the expected known bit pattern of the pilot frame, an error signal is derived, which in the described embodiment is either a step-up or step-down signal that is fed back to the mobile terminal to increase or decrease its transmitted pilot Eb/N0 level, respectively.

摘要： In a method for power reduction at a receiver, a first radio frame is processed to recover transmitted data based on transport format information. The transport format information is determined based on a combination of transport format information associated with a plurality of received radio frames rather than a single frame. In another method for power reduction at a receiver, whether transport format information associated with a first radio frame is different from transport format information associated with a second radio frame is determined. The transport channel data is then processed based on the determination. The first radio frame is received prior to the second radio frame, and the transport format information indicates a transport format for transport channel data received in the first and second radio frames.

摘要： At a base station receiver in a CDMA wireless communications system, in order to reduce reliance on the parameter values transmitted on a packet data control channel (PDCCH) to properly detect the high speed packet data transmitted on a packet data channel (PDCH) with which the PDCCH is code-division-multiplexed, data detection is performed using different possible values for at least one of the parameters and determining if a data packet derived from the PDCH detected under the different values produces a detected data packet that passes a CRC check. If a data packet derived from the received PDCH using a possible parameter value passes the CRC check, then the data packet is delivered to the output and an ACK is transmitted back to the transmitting mobile terminal.
