    Abstract: 本发明实施例提供了测量载波的方法和装置。该方法包括:接收来自基站的控制消息,控制消息用于指示非当前提供服务的载波的上下行子帧配置;基于控制消息,确定非当前提供服务的载波的上下行子帧配置;基于载波的上下行子帧配置,对载波进行测量。该装置包括接收模块、确定模块和测量模块。基于本发明实施例提供的技术方案,可以从控制消息获取非当前提供服务的载波的上下行子帧配置信息,从而可以利用更多的子帧信息来对非当前提供服务的载波进行测量,使得可以在更短的时间内得到更加准确的测量结果,测量载波的效率得以提高,并且由于测量过程仍然基于子帧进行,从而无需增加用户设备测量所需的硬件资源,不会导致用户设备芯片成本的上升。

    Abstract: A beamforming method is disclosed in the embodiment of the present invention, which includes the following steps: a base station transmitting code sequence in each beam, the code element in the code sequence having one-to-one relationship to a beam; receiving beam selection information sent by a terminal, the beam selection information being generated by the terminal according to the correlation between the received signal and the code sequence, the base station performing the beamforming on the data to be sent according to the beam selection information. With the embodiment of the present invention, the terminal generates beam selection information by implementing correlation calculation, and feeds the beam selection information back to the base station, the base station beamforms the data to be sent according to the beam selection information, the calculating amount of the terminal wouldn't be increased very much, the requirement of terminal complexity wouldn't be very high, the burden of the base station would be reduced greatly, in addition, the possibility of beamforming failure would be avoided greatly, and the performance of smart antenna system would be enhanced.

    Abstract: A data forwarding method during cell handover process is disclosed, which includes: a source base station forwarding the data having not transmitted to the user equipment to a target base station through packet data convergence protocol PDCP layer and/or radio link control RLC layer during performing cell handover. Furthermore, a method, system and device for transmitting data during cell handover process are also disclosed. The method, system and device provided in the present invention transmit the data having not been transmitted through PDCP layer and/or RLC layer respectively by using layered transmitting manner, therefore the data transmitting during cell handover process could be realized and the data losing caused by cell handover could be avoided.
