摘要： Methods and apparatus for receiving, processing, and decoding MIMO transmissions in communications systems are described. A non-Gaussian approximation method for simplifying processing complexity where summations are used is described. Use of a priori information to facilitate determination of log likelihood ratios (LLRs) in receivers using iterative decoders is further described. A Gaussian or non-Gaussian approximation method using a priori information may be used to determine a K-best list of values for summation to generate an LLR is also described.

摘要： Various embodiments are disclosed which predict the channel quality indicator (CQI) in High Speed Downlink Packet Access (HSDPA). The accuracy of CQI is crucial for HSDPA performance. In some HSDPA systems the CQI may be as much as three (3) subframes stale. Accordingly, the prediction of CQI values is required in order to efficiently schedule data for transmission over the communication channel. Various embodiments disclose first order adaptive IIR filters which are significantly less complex than the finite impulse response (FIR) counterparts and achieve similar accuracy. By minimizing the mean squared error (MSE), an exact gradient descent algorithm may be used as well as two embodiment pseudolinear regression algorithms.

The user equipment (140) performs a method for measuring at least one measurement quantity on a second cell on a second carrier operated by a second radio network node (120). The user equipment (140) receives (203), from the second radio network node (120), an indication indicative of the second carrier and a first parameter to be used by the user equipment for measuring said at least one measurement quantity. The first parameter relates to at least a first measurement period. The user equipment (140) determines (205) the first measurement period based on the first parameter. Moreover, the user equipment (140) measures (207) said at least one measurement quantity on at least the second cell on the second carrier over the first measurement period. The second network node (120) performs a method for providing the first parameter to be used by the user equipment (140).

摘要： A base station determines a muting configuration for reference signal (RS) transmission as a pattern defined by the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell may be differentiated from another cell by use of a different muting sequence, a different reference point, or both. Wireless communication apparatuses such as User Equipments (UEs) determine when the reference signals are muted in the cell based on the periodic muting sequence and the reference point received in assistance data transmitted by the base station. The network may alternatively utilize a common muting sequence with different reference points, a common reference point with different muting sequences, or different sequences and different reference points across multiple cells.
