    • Multipoint wireless communications are coordinated in cells with radiation that is emanated from antennas in an inward direction. In an example embodiment, an apparatus includes a first antenna, a second antenna, a third antenna and a controller. The first antenna emanates radiation from a first location in an inwardly direction for a cell. The second antenna emanates radiation from a second location in an inwardly direction for the cell. The third antenna emanates radiation from a third location in an inwardly direction for the cell. The controller coordinates the emanation of the radiation via the first, second, and third antennas so as to reduce intra-cell interference for remote terminals located within the cell. The coordination may be effected in accordance with one or more coordinated multi-point (transmission/reception) (CoMP) techniques. Different numbers of sub-cells and antennas per cell and different CoMP cell organizations may be implemented.
    • 多点无线通信在具有向内方向上从天线发出的辐射的小区中协调。 在示例实施例中,一种装置包括第一天线,第二天线,第三天线和控制器。 第一天线从单元的向内方向的第一位置发出辐射。 第二天线从小区的向内方向的第二位置发射辐射。 第三天线从单元的内向的第三位置发出辐射。 控制器通过第一,第二和第三天线来协调辐射的发射,以便减少位于小区内的远程终端的小区内干扰。 协调可以根据一个或多个协调的多点(发送/接收)(CoMP)技术来实现。 可以实现每个细胞和不同CoMP细胞组织的不同数量的子细胞和天线。

    • A method and apparatus for measuring a channel quality in wireless transmit/receive units (WTRUs) which are equipped with a subscriber based smart antenna. The WTRUs are equipped with a smart antenna so that the WTRU generates a plurality of directional beams and, optionally, an omni-directional beam. A dwell time is provided in a measurement period to switch a beam from an active beam to a non-active beam. The active beam is one of the plurality of directional beams or, optionally, the omni-directional beam, for communication with one or more serving base station(s). A beam is switched to a non-active beam at the initiation of the dwell time. Signals are received through the switched non-active beam, and samples of the received signals are generated. The samples are stored in a memory. Channel quality is measured using the samples, whereby the dwell time to measure the channel quality is minimized.
