    Abstract: To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.

    Abstract: A method and an apparatus for implementing channel measurement are disclosed in the present invention. The method includes: determining an antenna port subset, which is required to be measured, for a UE according to current state information of the user equipment UE; and informing the UE to perform channel measurement for the subset of antenna ports that is required to be measured and feed back channel state information. Through the present invention, when the state information of the UE meets a certain condition, the UE measures only the reference signals of a part of antenna ports, and feeds back channel state information for this part of antenna ports. Therefore, the overhead generated by the feedback of the UE to the channel state information is reduced.

    Abstract: A method for mobility management, an apparatus and a User Equipment (UE) are disclosed. The method includes: obtaining cell set information sent by a cell set in an access network; selecting a target cell set to which a UE may hand over according to the cell set information, and sending information about selection of the target cell set to the target cell set; and receiving information about at least one target cell decided by the target cell set, and providing the information about the target cell to the UE for handover. The method for mobility management between cell sets simplifies mobility management in multi-cell communication and improves performance of the communication system.

    Abstract translation: 公开了一种用于移动性管理的方法，装置和用户设备（UE）。 该方法包括：获取由接入网中设置的小区发送的小区集信息; 根据小区集信息选择UE可以切换到的目标小区集合，并将关于目标小区集合的选择的信息发送到目标小区集合; 以及接收关于由所述目标小区集决定的至少一个目标小区的信息，以及将所述目标小区的信息提供给所述UE进行切换。 小区组之间的移动性管理方法简化了多小区通信中的移动性管理，提高了通信系统的性能。
