    • The present invention involves a receiving method and apparatus for use in a communication system wherein a spread-spectrum signal containing information bits is transmitted within an environment tending to produce multipath fading. The receiving apparatus includes a channel estimator which estimates channel coefficients, preferably corresponding to the level of correlation between the various multipath components of the spread-spectrum signal and a cell-correlation signal. A channel selector is configured to select one or more of the multipath components based on the channel coefficients, typically choosing multipath components with the greatest level of correlation, a condition which is indicative of a high signal-to-noise power ratio. The channel selector also identifies time delay values representing the time delay between such selected multipath components, such time delay values being used by a spread-spectrum receiver to identify the selected multipath components for presentation on plural diversity branches. A combiner combines the diversity branches in a predetermined manner, typically by weighted summation using weighting factors produced by the channel selector. A decoder extracts information from the combined signal.
    • 本发明涉及一种在通信系统中使用的接收方法和装置,其中包含信息比特的扩频信号在趋向于产生多径衰落的环境中传输。 接收装置包括信道估计器,其估计信道系数,优选地对应于扩频信号的各种多径分量与小区相关信号之间的相关性水平。 信道选择器被配置为基于信道系数来选择一个或多个多径分量,通常选择具有最高相关级别的多径分量,表示高信噪比功率比的条件。 信道选择器还识别表示这种选择的多径分量之间的时间延迟的时间延迟值,这种时间延迟值被扩频接收机用于识别所选择的多径分量以便呈现在多个分集分支上。 组合器以预定的方式组合分集分支,通常通过使用由频道选择器产生的加权因子进行加权求和。 解码器从组合信号中提取信息。

    • Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference.
    • 公开了一种用于毫微微小区减少与重叠宏小区的干扰的方法。 毫微微小区确定宏小区的软频率重用(“SFR”)信息。 从该信息中,毫微微小区确定宏小区为其小区中心用户分配哪些频率子信道,哪些频率子信道被分配给小区边缘用户。 (为了克服与相邻宏小区的潜在干扰,小区边缘用户被给予更高的发射功率分布。)然后,毫微微小区从小区中心用户频率子信道中选择发送给毫微微小区的用户。 通过在小区中心用户频率子信道上进行发送,毫微微小区减少与重叠宏小区的干扰。 毫微微小区继续更新其对宏小区的SFR信息的知识,并且随着SFR改变而重新分配频率子信道。 如果宏小区检测到其小区中心用户之一对于毫微微小区“足够”,则宏小区重新分配小区中心用户作为小区边缘用户以克服干扰。
