Abstract: 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.

Abstract: 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.

Abstract: A random access method, an evolved Node B (eNB), and a terminal equipment are provided. The method includes: determining target component carriers to which a User Equipment (UE) is to be handed over, and notifying the UE of information about the target component carriers through a source eNB; and after receiving a dedicated random access preamble sent by the UE, sending a random access response message on at least one component carrier in the target component carriers. The terminal equipment includes: a handover command receiving unit, a sending unit, and a random response receiving unit. Therefore, in a random access procedure of cell handover, the eNB is capable of determining downlink component carriers that a UE monitors, thereby increasing utilization rate of downlink resources.

Abstract: This application relates to a discontinuous reception method. In the first time unit, for example, the first symbol, after a hybrid automatic repeat request HARQ feedback occasion of a sidelink HARQ process, a first terminal may start a drx-HARQ-RTT-TimerSL and start a drx-RetransmissionTimerSL when the drx-HARQ-RTT-TimerSL expires. During running of the drx-RetransmissionTimerSL, the first terminal monitors a physical downlink control channel. In this way, sidelink retransmission efficiency can be improved, an increase of a sidelink retransmission delay can be avoided, and sidelink-based applications, such as unmanned driving, automatic driving, assisted driving, intelligent driving, networked driving, intelligent networked driving, and car sharing in the field of artificial intelligence can be better supported.
