    • A method for implementing relay station downlink retransmission and a relay station are disclosed by the present invention. According to the situation of the least available radio resource number for retransmission data on a retransmission sub-frame, the relay station of the present invention performs corresponding physical layer processing in advance for the data to be retransmitted until the OFDM signal is generated, and retransmits the OFDM signal on the retransmission sub-frame. By the method of the present invention, the problem is resolved efficiently that the relay station cooperative communication cannot be performed normally due to the change of the radio resource number during downlink data retransmission, so that the normal implementation of the relay station downlink cooperative communication is ensured; furthermore, the method of the present invention does not induce any extra overhead and time delay, needs no signaling control, can be easily implemented, reduces the system complexity, ensures the flexibility of sub-frame configuration, thereby improving service quality and resource utilization rate.

    • 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。

    • A liquid zoom lens mounted on a portable terminal is provided. In the liquid zoom lens, a cylindrical body has upper and lower openings to which one pair of lenses is coupled. An auto-focus lens part includes a first insulating liquid layer, a first electrolyte layer, and a first lens. The first insulating layer and the first electrolyte layer are disposed to form an interface at a lower portion of the body. The first lens is disposed on the first electrolyte layer and has a periphery closely attached to a lower portion of an inner periphery of the body. An optical zoom lens part includes a second insulating liquid layer, a second electrolyte layer, and a second lens. The second insulating liquid layer and the second electrolyte layer are disposed to form an interface on the first lens. The second lens is fixed to be movable within the second insulating liquid layer, such that a periphery is closely attached to the inner periphery of the body. Accordingly, the auto-focus function and the optical zoom function can be simultaneously achieved through a single liquid lens whose curvature is varied by the difference of the inherent refractive index between the electrolyte and the insulating liquid.
