摘要： Disclosed are a data transmission method and apparatus. In embodiments of this application, a virtual cell comprising multiple cells can be configured, and data transmission can be implemented by time-division multiplexing among the cells, so that transmission carriers for a terminal service can be flexibly adjusted. Particularly, under the condition that transmission is deployed on an unlicensed spectrum resource, multiple cells operating on an unlicensed frequency band are aggregated into one virtual cell, and data transmission is implemented by time-division multiplexing among the cells; therefore, the interference in different frequency domains can be reduced and the system transmission efficiency can be improved.

摘要： Disclosed in the present application are a method and a device for intra-cell handover, and a method and a device for path switching, used for avoiding network side and user equipment (UE) side next hop chaining counter (NCC) desychronization when a UE switches out of a relay node (RN), so as to avoid communication failure. The method for intra-cell handover provided in the present application comprises: an RN determining whether the value of the difference between the UE side NCC and the NCC most recently received by the RN and allocated for the UE by a mobility management entity (MME) serving the UE meets the preset triggering requirement for intra-cell handover; if the value of the difference meets the triggering requirement, then the RN initiates intra-cell handover.

摘要： Embodiments of the present invention relate to the technical field of wireless communications, and specifically relate to a method, system and device for switching, for use in solving the problem in the prior art of the risk of communication interruption when a user equipment (UE) is switching due to greatly increased frequency and number of times of switching by the UE in an E-UTRAN network architecture. The method of the embodiments of the present invention comprises: a UE receives a DRB reconfiguration message from a macro base station; and the UE keeps a PDCP layer corresponding to all of the DRBs of a control side and of a user side at the macro base station, and switches other layers corresponding to some or all of the DRBs of the user side except the PDCP layer onto at least one base station. Because the embodiments of the present invention reduce the number of times of control side switching by the UE, in the case of increased frequency and number of times of switching by the UE in the E-UTRAN network architecture, the risk of communication interruption is reduced when the UE is switching.
