    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 determining a transmitted data rate, a received data frame may be decoded using different candidate rates to generate a first decoded bit sequence associated with each candidate rate. A first frame quality indicator and a first error metric may be generated for each of the candidate rates based on the associated first decoded bit sequence and a decoding metric for the associated first decoded bit sequence. One of the candidate rates may be selected as the transmitted data rate based on the first frame quality indicators, the first error metrics and an error metric threshold.

    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 and the packet is marked as having failed. Advantageously, by using the tail bits for error checking, no additional bits need to be allocated and transmitted for packet error detection purposes.

    摘要: One embodiment includes determining a channel quality prediction error indicative a channel quality for a first time interval. The first time interval includes of a plurality of subframes, and the channel quality prediction error is calculated based on a first channel quality indicator associated with a first sub-frame and a second channel quality indicator associated with a second sub-frame. The first subframe and the second sub-frame are temporally spaced from one another. For example, the first subframe and the second subframe are temporally spaced apart by at least the length of the first time interval. More specifically, the second subframe may be received the first time interval after the first subframe.

    摘要: A method of determining handoff of a user equipment (UE) to a transferee serving station from a transferor serving station at the transferee serving station is provided. The transferee serving station (e.g., a Node B) measures an energy level in a first portion of an uplink channel (e.g., an uplink high-speed dedicated physical control channel (HS-DPCCH)), the first portion of the uplink channel associated with the transferee serving station. In an example, the first portion of the uplink channel is where a channel quality indicator (CQI) is expected to be reported from the UE for the transferee serving station. The transferee serving station also measures an energy level in a second portion of the uplink channel, the second portion of the uplink channel associated with the transferor serving station. In an example, the second portion of the uplink channel is where a CQI is expected to be reported from the UE for the transferor serving station. The transferee serving station then determines when the UE has handed off to the transferee serving station based upon the measured energy levels.
