    • The present invention discloses a method for scheduling users in coordinated scheduling, which is applied in a long term evaluation-advanced system, a coordinated cell determines and stores user pairing information in initial scheduling, and the coordinated cell uses the user pairing information that has been stored to determine a scheduled user in subsequent iterative scheduling. The present invention also discloses a corresponding base station. With the scheduling schemes in the present invention, in intra-cell scheduling, user pairing information is stored in an initial scheduling process and is used in subsequent iterative scheduling without performing multiple user pairing search in the iterative scheduling, which reduces the computation amount in the iterative scheduling and system resources occupied by the iterative scheduling and accelerates the system processing time in a premise of not reducing the system performance, thereby making the performance in the whole domain trend to the optimal.
    • 本发明公开了一种在协调调度中调度用户的方法,其应用于长期评估高级系统中,协同小区在初始调度中确定并存储用户配对信息,协调小区使用已经被使用的用户配对信息 存储以确定后续迭代调度中的调度用户。 本发明还公开了一种相应的基站。 利用本发明的调度方案,在小区内调度中,将用户配对信息存储在初始调度处理中,并且在后续的迭代调度中使用,而不需要在迭代调度中执行多个用户配对搜索,这减少了 迭代调度和系统资源占用迭代调度,并在不降低系统性能的前提下加快系统处理时间,从而使整个领域的性能达到最优。

    • Method and apparatus are provided for estimating Time of Arrival (“TOA”). The method includes: performing channel estimation according to a Normal Burst (“NB”) free of interference and a local training sequence and generating a channel estimate, performing TOA estimation according to the channel estimate, and adjusting a synchronization position of the current NB according to a TOA estimation result. Interference to signals is cancelled before the TOA estimation, thus overcoming energy estimate deviation arising from interference in a strongly interfering radio environment, as occurs in the prior art, and preventing the impact on the TOA estimation. The disclosed methods and apparatus provide for more accurate energy estimates in a strongly interfering radio environment. The technical solution under the present invention does not require adjustment of the method of adjusting the search window.
    • 提供了估计到达时间(“TOA”)的方法和装置。 该方法包括:根据无干扰的正常突发(“NB”)和本地训练序列进行信道估计,并产生信道估计,根据信道估计执行TOA估计,并根据信道估计调整当前NB的同步位置 到TOA估计结果。 在TOA估计之前,对信号的干扰被消除,从而克服由于在现有技术中发生的强干扰无线电环境中的干扰引起的能量估计偏差,并且防止对TOA估计的影响。 所公开的方法和装置在强干扰无线电环境中提供更准确的能量估计。 本发明的技术方案不需要调整搜索窗口的调整方法。
