Data transmission method, base station and user equipment

Abstract

Embodiments of the present invention provide a data transmission method, a base station, and a user equipment. The primary base station configures the data transmission parameters of the secondary base station to assist the secondary base station in performing uplink and downlink data transmission to the UE. In this way, the primary base station and the secondary base station transmit and receive data according to the same data transmission parameters, so there is no need to perform too much processing on the data sent and received by the secondary base station, that is, the secondary base station can only retain simple buffering, encapsulation, and sending and receiving functions, or even only cache and transceiver functions, thereby simplifying the protocol design of the secondary base station, and helping to reduce the cost of the secondary base station, especially the micro base station serving as the secondary base station.

Description

[0001] This application claims the priority of an international patent application with application number PCT / CN2013 / 070703 and titled "Data transmission method, base station and user equipment" filed with the China Patent Office on January 18, 2013, the entire contents of which are incorporated by reference incorporated in this application. technical field [0002] The embodiments of the present invention relate to the technical field of mobile communication, and in particular, to a data transmission method, a base station, and user equipment. Background technique [0003] With the respective development of mobile communication and broadband wireless access technology, the services of the two penetrate each other. In order to meet the needs of mobile communication broadband and meet the challenges of broadband communication mobility, the mobile communication system introduces carrier aggregation (carrier aggregation, CA) and other technologies. [0004] The CA technology ...

AI Technical Summary

Problems solved by technology

[0005] At present, the protocol implementation of the secondary base station is also relatively complicated. Even a micro base station must implement the basic protocol stack and functions of a common base station, such as radio link control (radio link control, RLC) and media access control (media access control, MAC), so it cannot reduce the cost of the micro base station very well
