Abstract: A method in a network node for assisting a first user equipment in interference mitigation. The network node is comprised in a cellular communications network. The cellular communications network further comprises the first user equipment and a second user equipment. The second user equipment causes interference to the first user equipment when at least one of the first user equipment and second user equipment communicate by using Device-to-Device communication. The network node obtains information about the receiver of the first user equipment. The network node then determines one or more parameters required by the first user equipment for mitigating the interference. The parameters relate to the obtained information and to the interfering second user equipment. The network node then sends the one or more parameters to the first user equipment thereby assisting the first user equipment to mitigate interference caused by the second user equipment.

Abstract: Methods and apparatus are disclosed for improving a precoder selection process in a wireless communications system. In a normal precoder selection process, a precoder is selected from a codebook based on channel state information estimated from received reference signals. In between two received reference signals, a subset of precoders is cycled through and each precoder in the subset is iteratively selected for use by a transmitter to precode transmit signals. The subset of precoders may be adaptively modified based on predefined criteria.

Abstract: With the asymmetric resource sharing disclosed herein, a base station transmits fewer information symbols at some transmission times to one or more mobile terminals than to other mobile terminals at other transmission times. After transmitting the information symbols, the base station receives channel estimates from the mobile terminals, which the base station then use to generate synthesized signals representing estimates of the signals received at the mobile terminals. The base station subsequently combines complementary pairs of the synthesized signals to generate combined signals and transmits at least one of the combined signals to implement at least one virtual antenna for at least one of the mobile terminals.

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 radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.

Abstract: Channel quality metrics (such as SINR, BLER, and the like) are derived from a raw bit error rate (RBER), defined as the error rate of raw bits output by a demodulator. These initial raw bits are decoded and error-checked (or error-corrected). The error-free decoded bits are re-encoded, and the regenerated raw bits are compared to the initial raw bits to determine the RBER. The RBER is then converted to SINR, BLER, or other channel quality metric. The RBER-based metrics are derived from a data channel rather than reference signals, and hence more accurately reflect deviations from nominal transmission power level, and include receiver demodulator impairments.

Abstract: The teachings presented herein improve the processing of individual signals of interest included in a received composite signal by computing combining weights and/or signal quality estimates for each signal of interest, e.g., for linear equalization, based on either shared or non-shared correlation estimates. As a non-limiting advantage, the use of shared correlation estimates reduces computational loading as compared to the processing load that would be needed for computing non-shared correlation estimates for all signals of interest. As a further non-limiting advantage, the conditional use of shared and non-shared correlation estimates provides for the use of non-shared correlation estimates where signal characteristic(s) of one or more of the signals of interest warrant such usage, e.g., for one or more high-rate signals of interest.
