摘要： A base station receives channel quality reports from a plurality of mobile terminals. The channel quality reports from the mobile terminals indicate the signal power of the signals received by the mobile terminals from the base station and one or more interference parameters relating to the power of impairment components contributing to the total impairment of the received signal during a first time interval. The base station computes an estimated channel quality indication for a second time interval subsequent to the first time interval based on expected variations in the powers of the impairment components. The estimated channel quality indication for the second time interval is used by the base station to schedule the mobile terminals and to determine the transmission format.

摘要： A signal-to-interference estimate is generated using unknown data symbols in place of or in addition to pilot symbols. Data received over a data channel (traffic channel or control channel) are collected. The data symbols are then used to compute an observation metric based on deviations of the data symbols from a predetermined set of possible data symbols, wherein one of the data symbols and symbol constellation is normalized. A data channel signal-to-interference ratio is then computed based on the observation metric.

摘要： With a nonparametric G-Rake receiver, combining weights may be determined using a nonparametric mechanism in multiple-input, multiple-output (MIMO) scenarios. In an example embodiment, a method for a receiving device having a nonparametric G-Rake receiver entails calculating an impairment covariance matrix and determining combining weights. More specifically, the impairment covariance matrix is calculated based on a pilot channel using a nonparametric mechanism in a MIMO scenario in which a code-reuse interference term exists. The combining weights are determined for the nonparametric G-Rake receiver responsive to the impairment covariance matrix and by accounting for the code-reuse interference term.

摘要： A wireless communication system receiver compensates a received signal containing an IQ gain imbalance prior to performing frequency correction (32). The IQ imbalance in the signal is estimated after frequency correction, providing an IQ gain imbalance estimate (?n) for subsequent IQ gain imbalance compensation. The IQ gain imbalance estimation includes formulating (38) a plurality of hypotheses (Zt) of phase error between I and Q signal components, and taking as the actual phase error the hypothesis that yields the maximum power ratio between I and Q signal components. The maximum power ratio is differentiated with the respect to the IQ imbalance estimate. The IQ gain imbalance estimate is updated as a function of its prior value(s), the maximum power ratio, and the derivative of the maximum power ratio.

摘要： Methods and devices are provided whereby scrambling codes can be set in an improved way. In accordance with one embodiment a method is provided in a User Equipment for generating a second scrambling code or a second scrambling code group. The UE is configured for multi carrier operation receiving downlink transmission from a Universal Mobile Telecommunications System Terrestrial Radio Access Network on a set of at least two downlink carriers including an anchor carrier and at least a first secondary carrier. The method comprises determining a first scrambling code or a first scrambling code group associated with a first cell on the anchor carrier; and deriving a second scrambling code or a second scrambling code group associated with a second cell on said first secondary carrier using a predefined rule defining the relation between the second scrambling code or second scrambling code group and the first scrambling code or scrambling code group. Hereby interference suppression / cancellation processing is enabled in a receiver of a UE on secondary cells in multi-carrier scenarios that do not transmit the SCH, while minimizing the need for overhead in terms of signaling of the scrambling codes for neighbouring cells in a UTRAN system. Methods and devices for E-UTRAN are also described.

摘要： The number of blind decoding operations in a wireless communication receiver is reduced. In one embodiment, a candidate set of transport formats is formed by eliminating one or more allowed transport formats, thus reducing the number of decode operations to be performed. In another embodiment, a received data transmission is partially decoded according to each of a plurality of transport formats, and decode quality metrics associated with each transport format are inspected. Only the transport formats yielding sufficiently high quality metrics are utilized to fully decode the transmission. In other embodiments, upon failure to successfully decode a received transmission, it is assumed to be a retransmission with a missed control transmission, and one or more transport formats specifying the position of a previous transmission in a buffer are added to the candidate set of transport formats. The received retransmission and previously received transmission are then HARQ combined and decoded.

摘要： The teachings herein disclose methods and apparatus that simplify impairment correlation estimation for received signal processing, based on determining, for any given processing interval, which impairment contributors should be considered in the estimation of overall received signal impairment correlations. These simplifications reduce computational processing requirements, allowing reduced circuit complexity and/or reduced operating power, and improve receiver performance. A corresponding transmitter and transmission method include transmitting multiple information streams to targeted receivers according to ongoing scheduling, and controlling the ongoing scheduling to reduce the number of impairment contributors considered in impairment correlation estimation at the targeted receivers. In one embodiment, a receiver identifies which impairment contributors to consider based on receiving control information. In another embodiment, the receiver identifies the impairment contributors to consider based on background processing, e.g., background determination of parametric model fitting parameters for a plurality of impairment contributors, and observing those model fitting parameters over time.

摘要： The teachings herein disclose interference cancellation processing that uses hard decision logic for simplified estimation of interfering signals, in combination with soft scaling of the hard decisions for better interference cancellation performance, particularly in low signal quality conditions. In one aspect, the soft scaling may be understood as attenuating the amount of interference cancellation applied by a receiver, in dependence on the dynamically changing received signal quality at the receiver. More attenuation is applied at lower signal quality because the hard decisions are less reliable at lower signal qualities, while less (or no) attenuation is applied at higher signal qualities, reflecting the higher reliability of the hard decisions at higher signal qualities. Signal quality may be quantized into ranges, with a different value of soft scaling factor used for each range, or a soft scaling factor may be calculated for the continuum of measured signal quality.
摘要翻译：本文的教导公开了干扰消除处理，该处理使用硬判决逻辑来简化干扰信号的估计，结合硬判决的软缩放以获得更好的干扰消除性能，特别是在低信号质量条件下。在一个方面，软缩放可以被理解为根据接收机处的动态改变的接收信号质量来衰减由接收机施加的干扰消除的量。在较低的信号质量下应用更多的衰减，因为在较低的信号质量下硬判决不可靠，而在较高的信号质量下应用较少（或不）的衰减，这反映了较高信号质量下较难的决定的可靠性。可以将信号质量量化为范围，对每个范围使用不同的软缩放因子值，或者可以针对测量信号质量的连续性计算软缩放因子。
