    • Embodiments of the disclosure provide methods and apparatuses for handover in a heterogeneous network. According to the method, a candidate radio connectivity mode for use after handover from a source BS to a first target BS and/or a second target BS is determined; a first handover related message which comprises the candidate radio connectivity mode is sent to the source BS; and in response to receiving a second handover related message, the first target BS and/or the second target BS may be accessed, wherein the source BS is not associated with the first target BS, and wherein the first target BS is a LPN and is associated with the second target BS.

    • There is provided a method for detecting a symbol timing of a multi-antenna radio communication system. The method can significantly reduce a calculation amount in a space division multiplex OFDM system as compared to the conventional method, can detect an accurate symbol timing, and can easily be realized. In this method, at the symbol timing stage, a transmission side transmits a timing training sequence only from the first antenna. A reception side has a symbol timing divided into a rough timing stage and an accurate timing stage. In the rough timing stage, a phase correlation value between the reception signal of each antenna and its delay is calculated. The correlation value outputs of the respective antenna terminals are combined to decide the rough timing window. In the accurate timing stage, a convolution calculation is performed by using a real part of the reception symbol and a symbol of a real part of the training sequence. The convolution outputs of the respective antenna terminals are combined to obtain a plurality of output peak values. Within the rough timing window, the last convolution peak value is searched, thereby realizing the highly accurate timing of the symbol.
    • 提供了一种用于检测多天线无线电通信系统的符号定时的方法。 与常规方法相比,该方法可以显着减少空分复用OFDM系统中的计算量,可以检测准确的符号定时,并且可以容易地实现。 在该方法中,在符号定时阶段,发送侧仅从第一天线发送定时训练序列。 接收侧具有划分为粗略定时级和准确定时级的符号定时。 在粗略定时阶段,计算每个天线的接收信号与其延迟之间的相位相关值。 各个天线端子的相关值输出被组合以决定粗略的定时窗口。 在准确的定时阶段,通过使用接收符号的实部和训练序列的实部的符号来进行卷积计算。 各天线端子的卷积输出被组合以获得多个输出峰值。 在粗略定时窗口内,搜索最后一个卷积峰值,从而实现高精度的符号定时。
