    Abstract: A method and apparatus for optimizing sub-carriers of soft frequency reuse are provided for OFDM system with divided major sub-carriers and minor sub-carriers, wherein the method includes that: step 1, obtaining the user use information in the minor sub-carrier area of the cell by major sub-carriers and minor sub-carriers, adjusting the sub-carriers number allocated to the minor sub-carrier area dynamically according to the user use information for reducing the repeat minor sub-carriers number in the neighboring cells; step 2, measuring the user distribution information in the minor sub-carrier area of the cell by major sub-carriers and minor sub-carriers, adjusting the transmitting power of minor sub-carriers dynamically according to the user distribution information for reducing the transmitting power of the repeat minor sub-carriers in the neighboring cells. The neighboring cell interference caused by the minor sub-carriers is reduced on the base of assuring the system capacity and the user data rate by allocating the minor sub-carriers and adjusting the transmitting power of minor sub-carriers according to the user character covered in the minor sub-carrier area.

    Abstract: 一种多窗口显示方法及装置,该方法包括:针对已启动的应用,将该应用的各显示单元保存在唯一对应于该应用的容器中,其中,至少有两个已启动的应用,不同的应用对应的容器不同(S101),并根据设置的该应用的窗口属性和所述容器中保存的各显示单元,显示该应用的窗口(S102)。通过上述方法,由于每个应用的显示单元都保存在各自的容器中,从而,各应用的显示单元的活动状态不会相互影响,又由于应用会根据设置的窗口属性显示自身的窗口,因此,终端可以同时用多窗口对应地显示多个应用的实时内容。

    Abstract: An adjustable mechanism for jointing and fixing the lamp with the lamppost comprises a holder (1) jointing to the rear part of the lamp cover and having two sidewalls. A lamppost joint sleeve (2) is connected and fixed to a sidewall of the holder (1) by a run-through bolt assembly (3) . A contrate gear is provided between the adjacent sidewalls of the lamppost joint sleeve (2) and the holder (1) to facilitate the pivoting adjustment and the engagement. It not only facilitates mounting and ponsitioning as well as the adjustment of the operation angle, but also has good insulating ability and waterproof ability.

    Abstract: A method for determining to use diversity or multiplexing transmission based on channel quality indication includes the steps of: obtaining channel quality indication CQI values fed back by an user terminal within continuous N transmission times intervals before the current time, and calculating the average values M and standard deviations S of the obtained CQI values (302); establishing a sequential corresponding relation between the [M-S, M+S] set and the set SNR range (303); determining SNRs corresponding to the current CQI value according to the corresponding relation (304), wherein, the CQI values less than M-S are set to M-S, and the CQI values larger than M+S are set to M+S; calculating diversity and/or multiplexing gains according to the determined SNRs, so as to determine to use diversity or multiplexing to transmit the downlink data (305). A device is used to realize the method.
