Problems solved by technology

[0010] After research, it is found that due to the diversification of 5G business forms and scenarios, in order to meet various needs, various types of cells need to exist. From the perspective of network standards, there will be 2G, 3G, 4G, 5G cells and wireless protection cells. In terms of coverage, there will be macro cells, micro cells, and ultra-dense networks (Ultra-Dense Network, referred to as UDN), so there will be a variety of wireless access technologies (Radio Access Technology, referred to as RAT) integration problem
In the 5G network, services such as U-MTC require wireless communication to be ultra-reliable and ultra-low-latency, but the requirements for data throughput are not high. However, such ultra-reliable communication (Ultra -Reliable Communication, referred to as URC)
[0011] For the problem that the URC transmission of data cannot be realized in related technologies, no effective solution has been proposed so far

Abstract

The present invention provides a data transmission method and device, wherein the method includes: receiving information of the user equipment through an air interface connection established on a RAT supported by the user equipment, wherein the information is used to determine the multi-radio interface supported by the user equipment at least based on the information, judging whether to use multi-RAT transmission for the data sent to the user equipment; if the judgment result is yes, using multi-RAT to transmit data to the user equipment. Through the present invention, the problem that the ultra-reliable communication (URC) transmission of data cannot be realized is solved, and the URC transmission of data is realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and device. Background technique [0002] Wireless communication networks currently do not achieve connectivity anytime, anywhere. The reason is that currently commercially available wireless communication technologies can only provide relatively good connectivity in most scenarios, but cannot meet the needs of users in areas with weak coverage, extreme interference, or overloaded network resources. [0003] The future fifth-generation communication (5G) network will have considerable demand in the fields of Internet of Things, vehicle-mounted networks, telematics processing, and automation. There are currently no applications in these fields because the reliability of the current wireless communication network is not guaranteed enough. figure 1 It is a schematic diagram of a 5G network structure based on network functions according to related techno...
