摘要： This disclosure relates to using a dedicated reference subframes in a cellular communication system. According to one embodiment, a base station may transmit reference signals in a dedicated synchronization and measurement reference subframe. Neighboring base stations may also transmit reference signals in dedicated reference subframes in a temporally coordinated (synchronized) manner. The reference signals transmitted be each base station may be orthogonal with the reference signals transmitted by each neighboring base station. The reference subframes may be transmitted periodically, and data subframes may be transmitted between reference subframes. Some or all of the data subframes may not include cell-specific reference symbols, as their function may be unnecessary given the use of the dedicated reference subframes.
摘要翻译：本公开涉及在蜂窝通信系统中使用专用参考子帧。根据一个实施例，基站可以在专用同步和测量参考子帧中发送参考信号。相邻基站还可以以时间协调（同步）的方式在专用参考子帧中发送参考信号。每个基站发送的参考信号可以与每个相邻基站发送的参考信号正交。可以周期性地发送参考子帧，并且可以在参考子帧之间传送数据子帧。数据子帧中的一些或全部可能不包括小区特定的参考符号，因为在使用专用参考子帧的情况下，它们的功能可能是不必要的。

摘要： A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and / or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.
