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 method and a relay node (RN) for Un subframe configuration processing are disclosed. The method includes: receiving, by an RN, a radio resource control (RRC) reconfiguration message sent by an eNodeB (eNB), where the RRC reconfiguration message includes subframe reconfiguration information of the RN; and applying, by the RN, a RRC reconfiguration immediately upon reception of the RRC reconfiguration message, and applying a Un subframe reconfiguration. The foregoing technical solution can implement the Un subframe configuration of the eNB and the RN and improve communication quality.

Abstract: A handover processing method includes obtaining, by a relay station, information, where the information is used for determining whether a mobility management entity (MME) of a user equipment is in a mobility management entity pool (MME pool) to which a neighboring eNB belongs; and determining, by the relay station, that an X2 interface between a serving eNB of the relay station and the neighboring eNB cannot be used for handover if the MME of the user equipment is not in the MME pool to which the neighboring eNB belongs. The foregoing solutions enable the relay station to initiate a correct handover procedure.

Abstract: A communication device receives first indication information from a first network device. The first indication information indicates whether to enable a group receiving function. The first indication information is carried in SI, or the first indication information is indicated by a value of a short message indicator bit field in DCI. Then the communication device determines, based on the first indication information, whether to enable the group receiving function.

Abstract: One example method includes receiving, by a first node, a first message from a second node, wherein the first message is used to page a third node, instruct the third node to access a network, instruct the first node to provide a relay serving for the third node, instruct to set the third node to a low configuration mode, instruct to set the third node to a high configuration mode, or instruct to update system information. The first node can send a second message to a third node, where the second message is used to instruct the third node to access a network, instruct the third node to perform communication with a second node by using the first node, instruct to set the third node to a low configuration mode, instruct to set the third node to a high configuration mode, or instruct the third node to update system information.

Abstract: An uplink synchronization processing method, a User Equipment (UE), and a base station are provided. The method includes: receiving a component carrier (CC) uplink synchronization indication message sent by a base station, where the uplink synchronization indication message carries identification information of one or multiple newly configured CCs; sending synchronization signaling to the base station when determining that the uplink synchronization needs to be executed on all or a part of the one or multiple newly configured CCs corresponding to the identification information; and receiving a time advanced (TA) adjusting message that is sent by the base station according to the synchronization signaling, and applying a TA value carried in the TA adjusting message to the CC on which the uplink synchronization needs to be executed.
