摘要： Acknowledgment signaling in a multiple carrier environment is enabled with a multiple carrier codebook having code words that jointly encode acknowledgment for at least two carriers. For an example embodiment, there is a method in a remote terminal for acknowledgment uplink signaling in a multiple-carrier mode. First, a code word is determined that jointly encodes acknowledgment signaling for at least two carriers from a multiple carrier codebook that is stored in the remote terminal. The multiple carrier codebook includes eight code words that are defined to have a single carrier codebook as a sub-codebook of the multiple carrier codebook, each code word of the eight code words having a length of ten. The multiple carrier codebook achieves a minimum Hamming distance of four among the eight code words. Second, an uplink signaling message that includes the determined code word is transmitted from the remote terminal to a wireless network node.

摘要： A receive signal processor jointly detects two or more symbols in a signal-of- interest in the presence of one or more other MIMO signals. The signal-to- interference-plus-noise ratio for each signal-of-interest is determined by computing per- subcarrier signal-to-interference-plus-noise ratios for a plurality of subcarriers allocated to the signals-of- interest, and computing a total signal-to-interference-plus-noise ratio for the subcarriers based on the per-subcarrier signal-to-interference-plus-noise ratios of the subcarriers. A controller determines one or more transmission formats for uplink transmissions based on the signal-to-interference-plus-noise ratios. The process of computing per-subcarrier signal-to-interference-plus-noise ratio reflects the amount of MIMO interference already cancelled or still remaining in the signal arriving at the joint detector.

摘要： A wireless communication device or system generates transmit power control feedback for a received power control channel by determining a command error rate (CER), or by identifying a target signal quality for the power control channel according to a defined signal-quality-to-CER mapping function. Generally, the power control channel does not include error-coded data to use for CER estimation. However, in one embodiment, the channel does include known reference bits that are evaluated for CER estimation, with the estimated CER used to set the signal quality target for inner loop power control. In other embodiments, a computed reception error probability is used to identify a CER estimate according to a defined probability-to-CER mapping function. By way of non-limiting example, these embodiments may be used to provide power control feedback for power control commands transmitted on a Fractional Dedicated Physical Channel in WCDMA systems.

摘要： Exemplary received signal processing may be based on maintaining a model of received signal impairment correlations, wherein each term. of the model is updated periodically or as needed based on measuring impairments for a received signal of interest. An exemplary model comprises an interference impairment term scaled by a first model fitting parameter, and a noise impairment term scaled by a second model fitting parameters. The model terms may be maintained based on current channel estimates and delay information and may be fitted to measured impairment by adapting the model fitting parameters.based on the measured impairment. The modeled received signal impairment correlations may be used to compute RAKE combining weights for received signal processing, or to compute Signal-to-Interference (SIR) estimates. Combined or separate models may be used for multiple received signals. As such, the exemplary modeling is extended to soft handoff, multiple antennas, and other diversity situations.

摘要： A multi-stage equalizer implementing a low complexity sequence estimation technique referred to as serial localization with indecision (SLI). The multi-stage equalizer includes a plurality of stages including one or more preliminary stages and a final stage. Each stage includes a demodulator that simultaneously equalizes and demodulates an input signal to generate an intermediate sequence estimate comprising a sequence of intermediate symbol estimates. The preliminary stages further include a signal generator to generate the input signal to the next stage. The signal generator includes a modulator to re -modulate the intermediate symbol estimates generated in the same stage and a combiner to subtract the re -modulated symbols from the input signal to generate a residual signal for input to the next stage. The signal generator is not needed in the final stage. A combiner adds the intermediate sequence estimates produced in each stage to produce the final sequence estimate. The combiner may be implemented as a single combiner or as multiple combiners to generate cumulative intermediate symbols estimates at each stage. These intermediate symbol estimates can be used as affective pilot symbols to improve channel estimation for later stages.

摘要： At a node (110) of a wireless network (100), equalisation operations performed on signals received from a transmitter (130) are adaptively switched to be equalised by an iterative turbo receiver (210) or a linear receiver (230) A theoretical expression of a post-equalization SINR of a capacity-achieving receiver is used to estimate the post-equalization SINR performance of the turbo receiver (210). The estimated post-equalization SINR performance is then, used as a basis to determine whether the received signal is to be equalized by the turbo receiver (210) or the linear receiver (230).

摘要： Methods of recovering information encoded in a spread spectrum signal transmitted according to a spreading sequence in a communications medium are provided in which a spread spectrum signal is received from the communications medium and correlated with a spreading sequence to produce a plurality of time-offset correlations. Some of these time-offset correlations may be designed to cancel out known interfering signals. A subset of the plurality of time-offsets may then be selected, and corresponding traffic correlations may then be combined using a weighted combination to estimate information encoded in the transmitted spread spectrum signal. Receivers for implementing these methods are also provided.
