摘要： A method and apparatus for providing a link quality report in a wireless communication system supporting link adaptation. An input signal carrying data blocks in one or several transmission intervals of a reporting interval is received by a receiver (30) of the apparatus. A quality measurement unit (31) provides a link quality measure of the current reporting interval. A correction unit (32) corrects the link quality measure by determining a SIR loss of the link, which is induced by unmatched transmission parameter settings of a physical layer. Then, a link quality report for the current reporting interval is based on the corrected link quality measure and transmitted by the transmitter (34) to the transmitting unit, which will adapt the setting of physical layer parameters accordingly.

摘要： A sub-optimal method is disclosed for calculating the reliability values (soft values) for the bits of a multilevel signal. The log-likelihood values are approximated using only the dominant terms, so called max-log approximation, that is for each bit position only the two closest signal symbols of opposite bit value (S 8 ,S 6 ) are considered in the sum. The used modulation scheme is 16-QAM together with Gray-labelling. Two versions of approximation are proposed: one version consists of using the two distances between the received value and the two closest symbols of opposite bit value ( δ 1 , δ 2 ). In order to simplify and speed up the calculation, the second version consists of using the distance between the two closest symbols (δ 3 ) to approximate the distance between the second closest symbol and the received value. Furthermore, precalculated results are stored in look-up tables to speed up the calculation. Possible applications are especially bit interleaved coded modulation (BICM) together with soft-input decoding. It is also of interest for TCM and BCM schemes.

摘要： A method for scheduling a decoding process of coded data blocks transmitted over a link in a communication network. According to the method the coded data block is stored in a queue (71) if all decoders of a cluster (72) of iterative parallel decoders are unavailable. When any of the decoders of the cluster (72) is available the first coded block of the queue (71) is moved to that decoder. Also, according to the method it is possible to combine a stored coded block with a retransmitted coded block, which is decoded with an increased probability for successful decoding. Also, the invention relates to a communication apparatus adapted for carrying out the method according to the invention.

摘要： Improved ACK/NACK detection in a mobile terminal of a wireless communication system is disclosed. The ACK/NACK detection uses knowledge about the power of the acknowledgment/negative acknowledgment signal along with the probability that a DTX will occur to increase the probability that the ACK signal will be correctly detected. The probability that a DTX will occur is determined by observing the transmit power commands issued to the mobile terminal. A high number of power up commands relative to power down commands may indicate a poor quality uplink meaning that a DTX is likely to occur.

摘要： A method and system are described for performing fast and simple M-QAM detection on received signals, such as a 16-QAM signal, by estimating decision boundaries. Amplitude information is collected for in-phase an quadrature phase components of the received signal over a number of symbols. Average of the absolute value of the amplitude information of the in-phase components and of the quadrature phase components are determined over the number of symbols. The determined average absolute values of the in-phase and quadrature phase components provide a reference to produce the decision boundary estimates. estimates based on the estimated signal-to-interference ration (“SIR”) of the received signal to produce bias corrected decision boundary estimates.
