摘要： An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analogue portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analogue AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analogue gain can be common to all branches, based on measurement of the analogue signal in each branch.

摘要： Several advanced features in wireless network, such as multi-carrier operation, multi-RAT/multi-mode transmission, etc., may not be exploited to their fullest potential when uplink transmit diversity is used in conjunction with them. Several techniques described herein address these problems. An example method begins with the evaluation (610) of operating conditions for a mobile terminal transmitter and, based on the operating conditions, selectively activating or deactivating (620) multiple-antenna transmission by the mobile terminal. The operating conditions that are evaluated include,in some embodiments, the applicability of power backoff (maximum power reduction, or "MPR"), including whether Additional MPR (A-MPR) or power management MPR (P-MPR) are applicable. Other operating conditions that are evaluated may include uplink data rate requirements or limitations for the mobile terminal, and/or the actual or estimated status of the battery in the UE.

摘要： A user equipment, UE,(14) and a radio network node (12) can perform multiple input multiple output,MIMO,communication. The UE determines a precoder (50, 54) used in the radio network node for transmitting signals from multiple transmit antennas to the UE. Based on the determined precoder used, the UE determines receiver parameters (22, 60A, 60B) for receiving MIMO signals from the radio network node, and configures the UE to receive MIMO signals from the radio network node in accordance with the determined receiver parameters. The radio network node may provide information for transmission to the UE indicating the precoder used in the radio network node to permit the UE to determine a receiver configuration for receiving MIMO signals based on the determined precoder used by the radio network node.

摘要： The present invention relates to receiver apparatuses and methods of controlling weight adaptation in a receiver of a code multiplex telecommunications system with orthogonal spreading codes, wherein received discrete time signal samples are chip-level filtered by using a first equalising step. Additionally, the received discrete time signal samples are delayed by a time period corresponding to a data symbol and used in a second equalising step. Symbol estimates obtained from the first equalising step are non-linearly filtered and used as a desired response for the second equalising step in the following symbol period, wherein equaliser weights adapted in the second equalising step are used for the first equalising step. Alternatively, the second equalising step may be dispensed with and weight adaptation may be incorporated in a single equalising step. As an additional or alternative option, a hybrid equaliser architecture may be provided, where the above two-step equalisation is used during an active phase where a channel is allocated, while another weight updating scheme is used during an inactive phase where no channel is assigned. Thereby, detrimental effects of interference power can be reduced at low increase in complexity.
摘要翻译：本发明涉及在具有正交扩频码的码复用电信系统的接收机中控制加权自适应的接收机装置和方法，其中接收到的离散时间信号采样通过使用第一码片进行码片级滤波均衡步骤。另外，接收到的离散时间信号样本被延迟了与数据符号相对应的时间段并被用在第二均衡步骤中。从第一均衡步骤获得的符号估计值被非线性地滤波并用作下一个符号周期中的第二均衡步骤的期望响应，其中在第二均衡步骤中适配的均衡器权重用于第一均衡步骤。或者，可以省去第二均衡步骤，并且可以在单个均衡步骤中加入重量适配。作为附加或替代选择，可以提供混合均衡器架构，其中在分配信道的活动阶段期间使用上述两步均衡，而在未分配信道的不活跃阶段期间使用另一个权重更新方案。因此，在低复杂度的情况下，可以减少干扰功率的有害影响。
