Abstract: A combination of parametric and non-parametric approaches are disclosed for enabling pilot-based SINR estimation, for MIMO systems. The pilot-based SINR estimation embodiments account for preceding applied during either single-stream or multi-stream data transmission. The pilot-based SINR estimation embodiments also account for code reuse interference which arises during multi-stream data transmission when spreading codes are reused on the data channel. Accordingly, mismatches that exist between the data channel and the pilot channel because of preceding and/or code reuse are inherently accounted for by the pilot-based SINR estimation, embodiments disclosed herein.

Abstract: A block coding method and system for improving the reliability of Channel Quality Indicators (CQI) and antenna weight Indicators (AWI) reporting. A user terminal first generates 8-bit CQI and 2-bit AWI. A codeword generator produces a codeword responsive to these 10 CQI/AWI bits using a codebook or a generator matrix of a (20, 10, 6) code. The (20, 10, 6) code has a minimum Hamming distance of 6. The encoded codeword is transmitted to a receiver for decoding utilizing an identical (20, 10, 6) codebook.

Abstract: Systems and methods are disclosed for measuring received signal power at a mobile terminal in a cellular communications network in such a manner as to efficiently provide highly accurate received signal power measurements in the presence of strong inter-cell interference. In one embodiment, in order to measure received signal power for a measured cell, a mobile terminal selects weighting parameters for a number of time-frequency samples of a reference signal of the measured cell based, at least in part, on inter-cell interference from one or more synchronized interfering cells and inter-cell interference from one or more non-synchronized interfering cells. The mobile terminal applies the time-frequency samples of the reference signal of the measured cell and the corresponding weighting parameters to corresponding time-frequency samples of a received signal from the measured cell in order to obtain a measurement of the received power for the measured cell.

Abstract: A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

Abstract: A CDMA communication system uses a RAKE receiver, a code correlator and a multi-code joint detector to jointly detect symbols in two or more received signals contained within a composite signal. The RAKE receiver separates the composite signal into two or more RAKE output signals by despreading the composite signal using selected spreading codes. The multi-code joint detector jointly detects the symbols in the received signals using the RAKE receiver output signals, cross-correlations between the spreading codes generated by the code correlator, and RAKE combining weights based on a noise covariance matrix. The multi-code joint detector also includes a trellis that represents possible states and state transitions and a branch metric calculator for calculating branch metrics associated with the state transitions based on the RAKE receiver output signals and the cross-correlations between the spreading codes.

Abstract: In MU-MIMO scenarios, a target mobile terminal (220) can be exposed to data streams intended for other mobile terminals (222). If the target mobile terminal (220) is capable of interference cancellation, then a serving base station (210) can provide the target mobile terminal (220) with interference information so that the target mobile terminal (220) can efficiently cancel interferences due to these interfering data streams. The interference information includes one or more configuration information, each of which characterizes a related interfering data stream. The serving base station (210) provides the interference information over one or more radio resources that are exclusive allocated to the target mobile terminal (220) or are allocated for common listening. The serving base station (210) exchanges configuration information with neighboring base stations (212) over inter-BS links (250). The inter-BS links (250) use resources that are different from the radio resources used between the base stations (210, 212) and the mobile terminals (220, 222).
