Abstract

Disclosed in an embodiment of the invention is a data transmission method, comprising: when a first device needs to transmit traffic data, determining a first radio bearer and a second ratio bearer which are pre-established and associated with a public data network (PDN) connection, wherein the first radio bearer consists of a relay bearer between the first device and a relay user equipment and a second relay bearer between the relay user equipment and a second device, and the second radio bearer comprises a Uu bearer between the first device and the second device; receiving, by the first device, and by means of the first radio bearer and the second radio bearer, a first target traffic flow from the second device; and / or transmitting, by the first device, and by means of the first radio bearer and the second radio bearer, a second target traffic flow to the second device. Also provided is a corresponding device disclosed in an embodiment of the invention. The invention can increase throughput and reliability of transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission method and equipment. Background technique [0002] D2D (Device to Device, D2D for short) communication is a technology for direct communication between user equipment, which allows two user equipment 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 be located outside the network coverage of the macro cell or It may be located within the coverage area of ​​the macro cell, and the relay user equipment is generally located within the coverage area of ​​the macro cell. The relay user equipment can establish an RRC (Radio Resource Control, RRC for short) connection with the base station ...
