Abstract:
A method and a device for establishing an evolved packet system EPS bearer are disclosed. The method includes establishing, by a first base station to which UE belongs, a first EPS bearer based on a first CC for the UE, wherein the first EPS bearer is an EPS bearer between the first base station and the UE; and instructing, by the first base station, a second base station to establish a second EPS bearer based on a second CC for the UE, wherein the second EPS bearer is an EPS bearer between the second base station and the UE. The present invention enables the UE to aggregate carriers of different frequency ranges from the first base station to which the UE belongs and the second base station to which the UE belongs to transmit data, thus improving the throughput of the data transmitted by the UE.

The present disclosure discloses a communication method, a network device, user equipment, and a communications system. The communication method includes determining, by a network device, to allocate a first secondary cell group (SCG) to user equipment, and sending, by the network device, first configuration indication information to the user equipment, where the first configuration indication information indicates at least one type of the following configuration transmitting uplink control information related to a cell in the first SCG by using a physical uplink control channel (PUCCH) of a first cell, where the first cell belongs to a second SCG of the user equipment, or processing data transmission on at least one cell in the first SCG by using a layer 2 functional entity located in the second SCG. The communication method disclosed in the present disclosure can reduce complexity of UE.
Abstract:
The present disclosure provides a data transmission processing method including: receiving first indication information and saving context information of user equipment according to the first indication information, where the context information includes identification information of the user equipment; and decoding a PDCCH based on the identification information of the user equipment, to obtain second indication information, where the second indication information is used to determine that the user equipment is a paged object or that there is a service of the user equipment. The indication information meant for the paged object is carried in the PDCCH, so that the user equipment can determine, depending on whether the indication information can be successfully obtained, whether the user equipment is the paged object or has a service, and perform subsequent processing, for example, connecting to a network, when determining that the user equipment is the paged object or has a service.

The data transmission method in a heterogeneous network comprises: a macro base station carrying control information in a subframe, transmitting the control information to a terminal in a control-frequency band, and informing a low power node of the control information; according to the control information, the low power node carrying data information in a subframe and transmitting the data information to a terminal by a data-frequency band; the control-frequency band and the data-frequency band are statically deployed, and the control-frequency band and the data-frequency band are non-overlapped.
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 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.

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.
