    • Embodiments of the present invention provide a method and an apparatus for determining reference signals. A User Equipment (UE) obtains group hopping information and/or sequence hopping information of a UE-specific reference signal from cell-specific system information broadcasted by an eNB. The UE receives UE-specific control information transmitted by the eNB to the UE. The UE generates a UE-specific reference signal of a first slot according to the group hopping information and/or sequence hopping information of the broadcasted cell-specific reference signal. If the UE-specific control information indicates that group hopping and/or sequence hopping of UE-specific reference signals is disabled, the UE generates a UE-specific reference signal of a second slot in a same frame with the first slot according to the UE-specific reference signal of the first slot. The UE is able to determine the reference signals when multiple UEs share physical resource blocks.
    • 本发明的实施例提供了一种用于确定参考信号的方法和装置。 用户设备(UE)从由eNB广播的小区特定系统信息获取UE特定参考信号的组跳频信息和/或序列跳频信息。 UE向UE发送由eNB发送的UE专用控制信息。 UE根据广播小区特定参考信号的组跳频信息和/或序列跳频信息生成第一时隙的UE特定参考信号。 如果UE专用控制信息指示UE特定参考信号的组跳和/或序列跳跃被禁用,则UE根据UE生成与第一时隙相同的帧中的第二时隙的UE专用参考信号 - 第一时隙的特定参考信号。 当多个UE共享物理资源块时,UE能够确定参考信号。
