Embodiment Construction

[0138] In the bearer offload scenario, there is currently no solution for how to transmit data between the base stations of the scheduling terminal and the terminal. In order to solve the above problems, the embodiment of the present invention provides a bearer offload scenario for the first bearer offload architecture Data transmission method and device. The embodiment of the present invention is applicable to RLC TM mode, RLC UM mode and RLC AM mode.

[0139] In the embodiment of the present invention, the terminal supports bearer offload, and the base station that schedules the terminal also supports bearer offload, and there is a primary base station MeNB (such as a macro base station) in the base station that schedules the terminal, and the rest of the base stations are secondary base station SeNB (such as a local node ), the embodiment of the present invention does not limit the number of SeNB, wherein, the architecture of MeNB and SeNB in ​​the embodiment of the present...

Abstract

The embodiment of the invention discloses a data transmission method of a shunt bearing scene and a device thereof, and is used for solving a problem of solution for data transmission between all base stations scheduling a terminal and the terminal under the shunt bearing scene. The method of the embodiment of the invention comprises the steps that the terminal working under scheduling of multiple base stations receives downlink data, and the base stations transmitting the downlink data are confirmed according to communities bearing the downlink data; and de-multiplexing processing is performed on the downlink data by the terminal, and the generated MAC SDU is transmitted to an RLC entry corresponding to an RB scheduled by the base stations of the terminal to be processed, wherein the terminal comprises RLC entries corresponding to different base stations as for each RS commonly scheduled by the multiple base stations. Therefore, data transmission between the terminal and the different base stations scheduling the terminal is realized under the shunt bearing scene.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data transmission method and device for bearer offload scenarios. Background technique [0002] Currently, the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) is composed of eNBs (evolved base stations). For the network architecture of E-UTRAN, see figure 1 As shown, wherein, the eNB completes the access network function, and communicates with the user equipment (UE, User Equipment) through the air interface. There is both a control plane connection and a user plane connection between the UE and the eNB. [0003] For each UE attached to the network, there is a Mobility Management Entity (MME) to provide services for it. The MME is connected to the eNB through the S1-MME interface, and the S1-MME interface provides control plane services for the UE. Including mobility management and bearer ma...
