Abstract

The embodiment of the invention discloses a data transmission method. The method comprises that when a first device needs to transmit business data, a first wireless carrier and a second wireless carrier connected and associated with a prebuilt public data network PDN are determined; wherein the first wireless carrier is composed of a first relay carrier between the first device and a piece of relay user equipment, and a second relay carrier between the relay user equipment and a second device; the second wireless carrier is composed of a Uu carrier between the first device and the second device; the first device receives first target business streams from the second device through the first wireless carrier and the second wireless carrier; and or the first device sends second target business streams to the second device through the first wireless carrier and the second wireless carrier. Correspondingly, the embodiment of the invention also discloses a device. Through adoption of the method and the device provided by the invention, the transmission throughput capacity and reliability can be improved.

Description

technical field

[0001] The present invention relates to the field of communications, and in particular, to a data transmission method and device. Background technique

[0002] D2D (Device to Device, D2D for short) communication is a technology for direct communication between user equipments, allowing two user equipments to communicate with each other without going through the uplink and downlink between the base station and the device. D2D relay communication is a communication method based on D2D communication technology. The D2D relay communication system includes remote user equipment and relay user equipment. The remote user equipment may not only be located outside the network coverage of the macro cell, but also It may be located within the coverage of the macro cell, and the relay user equipment is generally located within the coverage of the macro cell. The relay user equipment can establish an RRC (Radio Resource Control, Radio Resource Control, RRC for short) con...
