摘要： Channel estimation accuracy is improved by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel allocated to the same receiver. The physical control channel may be a DPCCH, E-DPCCH or other type of physical control channel allocated to a receiver for facilitating uplink or downlink communication. Regardless, the control channel power level is optimized for channel estimation as a function of data transmission rate and/or transport format. In one embodiment, control channel symbols are transmitted for use in channel estimation by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a physical data channel allocated to the receiver (200). Control channel symbols are transmitted to the receiver over the physical control channel at the adjusted power level (202). The receiver uses the control channel symbols to perform channel estimation (204).

摘要： Systems and methods according to these exemplary embodiments provide for methods and systems for improving the signal-to-interference-plus-noise ratio (SIR) estimation between a mobile communications device and a base station (BS) for improving power control. A first SIR estimate is generated based on signals received on at least a first channel and a second SIR estimate is generated based on signals received on a second channel. A correction factor for the second SIR estimate is generated based on at least the first SIR estimate, and the second SIR estimate is adjusted with the correction factor. The first SIR estimate can, optionally, be generated using channel coefficients generated from signals received on both the first channel and the second channel.

摘要： The teachings presented herein provide, among other things, improved power control stability and increased system capacity in a wireless communication network by raising signal quality targets for mobile stations engaged in scheduled uplink data transmissions and lowering those signal quality targets at the end of such transmissions. As one example, the teachings herein are applied to the Enhanced Uplink (EUL) in a Wideband CDMA (WCDMA) network. In that context, the target received signal quality (e.g., SIR) for a given mobile station's Dedicated Physical Control Channel (DPCCH) signal is raised for times when the mobile station is engaged in a scheduled data transmission via its Enhanced-Dedicated Physical Data Channel (E-DPDCH), and lowered at other times. Doing so prevents the power control loop from “chasing” the potentially dramatic changes in mobile-specific interference conditions that arise in a scheduled uplink environment.
摘要翻译：本文提供的教导尤其提供了通过提高参与调度的上行链路数据传输的移动站的信号质量目标，并且在这种传输结束时降低这些信号质量目标，来改善无线通信网络中的功率控制稳定性和增加的系统容量。作为一个示例，本文的教导应用于宽带CDMA（WCDMA）网络中的增强型上行链路（EUL）。在这种情况下，针对给定的移动台的专用物理控制信道（DPCCH）信号的目标接收信号质量（例如，SIR）在移动台通过其增强专用物理数据信道参与调度的数据传输时被提升（E-DPDCH），并在其他时间降低。这样做可以防止电源控制环路“追逐”在预定的上行链路环境中出现的移动专用干扰条件的潜在的巨大变化。

摘要： The present invention relates to a system and a method for transmitting data between a first terminal and a communication network access point. The method may comprise the steps of defining a first set of scrambling codes and a second set of scrambling codes different from the first set of scrambling codes. Further, the method may comprise defining a first selection scheme for a first parameter. The method may still further comprise determining a current parameter value for the first parameter and evaluating the current parameter value on the basis of the first selection scheme and selecting a scrambling code from the first set of scrambling codes or the second set of scrambling codes based on the evaluation. Even further, the method may comprise packaging and transmitting data between the first terminal and the communication network access point using the selected scrambling codes.

摘要： A method and apparatus for controlling the transmit power of a mobile device in a mobile communication network takes the level of self-interference into account to perform inner-loop power control. For normal inner-loop power control, a signal quality estimate is compared to a signal quality target and power control commands are generated based on the comparison. When self-interference is the dominant impairment in the received signal, a “fast break” is introduced to change inner-loop power control command generation.
