摘要： This application provides a reference signal transmission method and an apparatus, to resolve a prior-art problem of relatively high overheads of resources occupied by transmitted reference signals in a communications system. The method includes: configuring, by a transmitting device, one reference signal group corresponding to one port in the first time symbol, and configuring one reference signal corresponding to the port in each of time symbols except the first time symbol. This reduces overheads of resources occupied by transmitted reference signals in the communications system and improves service data transmission efficiency while ensuring that a receiving device can obtain a channel parameter of the port.

摘要： A method, a system and an apparatus can be used for transmitting data in a CA manner. A first base station currently serving a user equipment (UE), creates EPS bearers under different component carriers CC Groups for the UE. The UE sets different access stratum entities corresponding to the CC Groups to process data in the process of creating the EPS bearers. The UE determines, when transmitting or receiving data, a corresponding CC Group according to an EPS bearer that bears the data. An access stratum entity corresponding to the CC Group processes the data that needs to be transmitted or received, a site is a first base station currently serving the UE or a second base station currently serving the UE.

摘要： A handover method and a base station are provided. The handover method may include: when a UE needs to be handed over, obtaining bearer context information of the UE in a first base station; sending a handover request to a target base station, where the handover request carries the bearer context information; and after receiving a handover response that is returned by the target base station and indicates that the handover is agreed to, sending a handover command to the UE so that the UE is handed over to the target base station. Based on the above technical solutions, the UE handover can be implemented quickly in the case of using multiple carriers and the current service of the UE can be recovered quickly, which can improve communication experience of a user.
