    • PROBLEM TO BE SOLVED: To provide a system for overlapping cells for wireless coverage in a cellular communication system.SOLUTION: The system includes a beam-weight generator, and a beamformer coupled to the beam-weight generator. The beam-weight generator is configured to generate a plurality of beam weights including at least first and second sets of beam weights. In addition, the beamformer is configured to apply the first and second sets of beam weights to signals in a cellular communication system. The cellular communication system provides coverage over a geographic region divided into cells arranged in overlapping first and second layers of cells having criteria optimized for communication by respective, distinct first and second types of user terminals. In this regard, the criteria are reflected in the first and second sets of beam weights.
    • 要解决的问题:提供一种用于在蜂窝通信系统中重叠用于无线覆盖的小区的系统。解决方案:该系统包括光束权重发生器和耦合到光束重量发生器的波束形成器。 光束重量发生器被配置为生成包括至少第一和第二组光束重量的多个光束权重。 另外,波束形成器被配置为将第一和第二组波束权重集合应用于蜂窝通信系统中的信号。 蜂窝通信系统提供对被划分成重叠的第一和第二层小区中的小区的地理区域的覆盖,该小区具有针对由相应的,不同的第一和第二类型的用户终端进行通信而优化的标准。 在这方面,标准反映在第一组和第二组梁重量中。

    • PROBLEM TO BE SOLVED: To provide a relay and distribution apparatus for a cellular communication system, the apparatus being capable of utilizing a high-order frequency reuse pattern with low control-channel overhead.SOLUTION: The relay and distribution apparatus comprises an antenna system configured to lay down beams in overlapping a first N-cell frequency reuse pattern and M second N-cell frequency reuse patterns. The first frequency reuse pattern may be for communication of control channels of a cellular communication system, and the second frequency reuse patterns may be for communication of traffic channels exclusive of control channels of the cellular communication system. The second frequency reuse patterns may be staggered with one another. Cells of the second frequency reuse patterns may have a size only a fraction of which is for transmission of traffic channels any of which may be assignable through a control channel of the first reuse frequency pattern.
    • 要解决的问题:为了提供一种用于蜂窝通信系统的中继和分配装置,该装置能够利用具有低控制信道开销的高阶频率重用模式。解决方案:中继和分配装置包括配置的天线系统 以重叠第一N个小区频率复用模式和M个第二N个小区频率重用模式的波束。 第一频率复用模式可以用于蜂窝通信系统的控制信道的通信,并且第二频率重用模式可以是用于通信的,不包括蜂窝通信系统的控制信道的业务信道。 第二频率重用模式可以彼此交错。 第二频率复用模式的小区可以具有只有其中一小部分的大小用于业务信道的传输,其中任何一个可以通过第一重用频率模式的控制信道来分配。
