A kind of highly reliable business transmitting method
Technical field
The present invention relates to a kind of wireless communication fields, more particularly to a kind of highly reliable business transmitting method.
Background technique
5G will meet people in the diversified business demand in the various regions such as inhabitation, work, leisure and traffic, even if close Collect residential quarter, office, stadium, outdoor rally, subway, through street, high-speed rail and wide area covering etc. with ultra high flux density, Superelevation connects number density, the scene of ultrahigh-mobility feature, or user provides ultra high-definition video, virtual reality, enhancing The ultimate attainment business experiences such as reality, cloud desktop, game on line.At the same time, 5G will also penetrate into Internet of Things and various industries field, It is merged with industrial plants, Medical Instruments, vehicles even depth, effectively meets the multiplicity of the vertical industries such as industry, medical treatment, traffic Change business demand, realizes really " all things on earth interconnection ".
5G application scenarios can be divided into two major classes, i.e. mobile broadband (MBB, Mobile Broadband) and Internet of Things (IoT, Internet of Things).Wherein, the major technique demand of mobile broadband access is high capacity, provides high data Rate, to meet constantly increasing for data traffic requirement；Internet of Things is mainly by machine communication (MTC, Machine Type Communication) the driving of demand can be further divided into two types, magnanimity machine communication including low rate (MMC, Massive Machine Communication) and the highly reliable machine communication of low time delay.It is logical for the magnanimity machine of low rate Letter, the access of magnanimity node low rate, the data packet of transmission is usually smaller, and interval time can be relatively long, the cost of this kind of node It generally also can be very low with power consumption；The machine communication highly reliable for low time delay, is mainly directed towards real-time and reliability requirement compares High machine communication, such as real-time alert and real time monitoring etc..
And in the 5th Generation Mobile Communication System, the core scenario for needing most further investigation is exactly machine communication, such as industry 4.0, car networking and robot etc., then, how to guarantee reliable data transmission in Internet of Things, is urgently to be resolved at present ask Topic.
Summary of the invention
The technical problem to be solved by the present invention is to need to provide one kind data in existing machine communication can be overcome to transmit The problem of Reliability comparotive difference, and then improve the service efficiency of network and the business transmitting method of reliability.
In this regard, the present invention provides a kind of highly reliable business transmitting method, comprising the following steps:
Step S1, the first communication node generate transmission data block, determine transmission institute according to the type of the transmission data block State the corresponding reliability step information of transmission data block, first communication node sends the reliability step information and described The location information of first communication node gives the second communication node；
