摘要： A mobile terminal measures interference over multiple measurement periods and generates interference probability data based on the statistical distribution of the interference measured. The interference probability data may describe, for example, the probability of each possible level of interference expected at the mobile terminal. The mobile terminal derives channel quality information as feedback to a base station based on this interference probability data (e g., when noise at the mobile terminal falls below a threshold) Ln one embodiment the mobile terminal does so by estimating from the interference probability data the probability of success folly receiving a transmission if certain feedback information is reported. Derived in this way, the feedback information more reliably indicates interference likely present at the mobile terminal when the base station sends the transmission. Accordingly, the base station controls the transmission based on the feedback information, and in some embodiments, also based on the interference probability data.

摘要： Teachings herein provide reduced complexity channel state information (CSI) reporting for a successively decoded, precoded multi-antenna transmission. A wireless communication device reports CSI by forming, for each candidate transmission rank of the transmission, a sequence of codewords by iteratively adding codewords allowed for that rank to the sequence. At any given point in the sequence, the device adds the codeword expected to yield the highest individual information rate if decoded at that point in the sequence, considering the different rates possible under different precodings of the transmission. The device then computes, for each rank, a sum information rate across the codewords in the sequence formed for that rank, selects the rank having the highest sum information rate, and reports the selected rank along with the sequence formed for that rank. CSI reporting complexity is reduced because the device constrains its evaluation to only some of the possible decoding sequences.

摘要： In one embodiment, a receiver implements a method of demodulating a set of symbols dispersed within a time-frequency grid of a received OFDM signal The method includes determining which one of two or more demodulators is preferred for use in a given region of the time-frequency grid by evaluating detection statistics generated by the demodulator for the set of symbols. Each demodulators operates according to different demodulation parameters that correspond to different interference assumptions The method further includes recovering the set of symbols for decoding using whichever demodulator is preferred for each symbol according to the region from which the symbol is recovered. The method may be further extended by updating each demodulator's demodulation parameters using reference and/or data symbols from the regions where that demodulator is preferred, and recovering the desired symbols using the updated demodulation parameters. Such updating can be further iterated, for additional demodulation parameter refinement

摘要： A joint demodulator is configured to generate an estimated first frequency or first frequency error for the first signal and an estimated second frequency or second frequency error for the second signal. A first long-term automatic frequency control is responsive to the estimated first frequency or first frequency error, wherein the joint demodulator is responsive to the first long-term automatic frequency control. A second long-term automatic frequency control is responsive to the estimated second frequency or second frequency error, wherein the joint demodulator is responsive to the second long-term automatic frequency control. First and second local automatic frequency controls also may be included in the joint demodulator, wherein the first long-term automatic frequency control is responsive to the first local automatic frequency control and the second-long-term automatic frequency control is responsive to the second local automatic frequency control. The first long-term automatic frequency control and the second long-term automatic frequency control can produce respective first and second frequency offset signals that are applied to the joint demodulator. Alternatively, a difference between the first and second frequency offsets is applied to the joint demodulator and the first frequency offset is applied to a downconverter that downconverts the jointly received first and second signals and provides the downconverted signals to the joint demodulator.

摘要： A communications system and method for compensating for an interferer signal in a received signal comprising a radio processor for filtering the received signal (310), and a demodulator (320) coupled to the radio processor for demodulating the filtered received signal. A channel quality estimator (330) coupled to the demodulator determines a channel characteristic based on instantaneous noise values of the received signal, for controlling the demodulation of the received signal to compensate for the interferer signal responsive to the channel characteristic. Further, where the channel characteristic is a first channel characteristic, the channel quality estimator determines a second channel characteristic based on instantaneous noise values of the received signal and controls demodulation of the received signal to compensate for the interferer signal responsive to the first and the second channel characteristics.
