    • The invention relates to apparatus and methods for managing data swap in a migration of virtual memory data of a virtual machine. In one embodiment, an apparatus comprises a receiving unit configured to receive a migration instruction and the second site information; a copying unit configured to copy memory data to a sub-logical unit in the first storage device; and a notifying unit configured to send a notification to instruct the second host to read the memory data from a mirror logical unit of a sub-logical unit in the second storage device. The apparatus modifies a mirror direction between the first and second storage devices and modifies a path table related to the first and second storage devices. Data of the virtual machine can be migrated and swapped in a metro mirror manner, thereby the virtual machine data can be migrated across sites without affecting system operation.
    • 本发明涉及用于在虚拟机的虚拟存储器数据的迁移中管理数据交换的装置和方法。 在一个实施例中,一种装置包括被配置为接收迁移指令和第二站点信息的接收单元; 复制单元,被配置为将存储器数据复制到第一存储设备中的子逻辑单元; 以及通知单元,被配置为发送通知以指示所述第二主机从所述第二存储设备中的子逻辑单元的镜像逻辑单元读取所述存储器数据。 该装置修改第一和第二存储装置之间的镜像方向,并修改与第一和第二存储装置相关的路径表。 虚拟机的数据可以以城域镜像的方式进行迁移和交换,从而可以在不影响系统操作的情况下跨站点迁移虚拟机数据。

    • An eNB, user equipment, system and method for transmitting sounding reference signals by using multiple antennas are disclosed in the present invention, which can reduce overhead of uplink sounding reference signals. The method includes: if an Advanced Long Term Evolution (LTE-A) system has uplink multiple antennas, an eNB configures respectively transmission periods of Sounding Reference Signals (SRSs) which are transmitted over each antenna for a User Equipment (UE); according to the configuration by the eNB, the UE transmits an uplink SRS over each antenna with the corresponding SRS transmission period. The present invention can reduce the uplink SRS overhead in the system remarkably if there are multiple antennas.
    • 本发明公开了一种用于通过使用多个天线发送探测参考信号的eNB,用户设备,系统和方法,其可以减少上行探测参考信号的开销。 该方法包括:如果高级长期演进(LTE-A)系统具有上行多个天线,则eNB分别为用户设备(UE)分别在每个天线上发送的探测参考信号(SRS)的传输周期进行配置; 根据eNB的配置,UE以相应的SRS传输周期在每个天线上发送上行SRS。 如果存在多个天线,本发明可以显着地减少系统中的上行SRS开销。
