摘要： A method of tracking on-time errors may include producing first and second metrics from accumulated signal samples of a received data frame, and calculating a sum of, and a difference between, the first and second metrics. The calculated difference and sum values may be used to determine an estimated on-time error for the received data frame and a corrected timing error control value to be applied to the on-time error. The accuracy of the estimated on-time error may be evaluated based a signal quality metric to determine whether the corrected timing error control value is to be applied to the estimated on-time error or whether the timing adjustment for the on-time error is to be stopped.

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： 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, an estimated E-DPDCH to DPCCH amplitude ratio that represents a scaling factor for the soft symbols is determined, and the soft symbols are scaled by the scaling factor to enable the soft symbols to be processed by the log-MAP turbo decoding algorithm in the base station receiver.

摘要： In one embodiment of the method, a channel quality metric for a first subframe is estimated based at least in part on a channel quality metric for a previous subframe, and a channel quality metric for a second subframe is estimated based at least in part on the channel quality metric for the previous subframe. Here, the second subframe is later in time than the first subframe. Then, a channel quality metric for a time slot located between the first and second subframes is estimated based on the channel quality metrics for the first and second subframes.

摘要： A decoding method is carried out in a receiver configured to accept format information relating to sequences of input data, to use format information in the decoding of each input sequence, and to issue an acknowledgement signal in the event that an input sequence is successfully decoded. The method involves receiving a format message pertaining to a new input sequence, searching a candidate set of format indices an index best satisfying a criterion for matching to the format message, and selecting the index giving the best match. Before searching, the receiver reads the acknowledgement signals issued in response to the decoding or attempted decoding of recent input sequences. If the acknowledgement signals satisfy an appropriate condition, the search is limited to fewer than all the indices in the candidate set. The format information that corresponds to the selected index is used in decoding the new input sequence.

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： A method of adjusting a power level of communications over a channel in a wireless communications network. In the method, a determination (e.g., by a radio network controller (RNC)) is made regarding a number of base stations actively communicating with a mobile station. For example, the determination may indicate whether the mobile station is engaged in soft handoff or simplex mode. One of a plurality of power control algorithms (e.g., a fixed offset power control algorithm, a channel quality indicator (CQI) power control algorithm, etc.) is selected based on the determination. A power level of communications over the channel (e.g., a downlink communications channel to the mobile station) is then adjusted in accordance with the selected power control algorithm.
