A kind of highly reliable business transmitting method
Technical field
The present invention relates to a kind of wireless communication field more particularly to a kind of highly reliable business transmitting methods.
Background technology
5G will meet diversified business demand of the people in various regions such as inhabitation, work, leisure and traffic, even if close Collect residential quarter, office, stadium, outdoor rally, subway, through street, high ferro and wide area covering etc. with ultra high flux density, Superelevation connection 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 various of the vertical industries such as industry, medical treatment, traffic Change business demand, realize really " all things on earth interconnection ".
5G application scenarios can be divided into two major class, 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 power 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, the magnanimity machine communication including low rate（MMC, Massive Machine Communication）The highly reliable machine communication with low time delay.The magnanimity machine of low rate is led to 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；For the highly reliable machine communication of low time delay, it 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 4.0th, car networking and robot etc., then, how to ensure reliable data transmission in Internet of Things, be urgently to be resolved hurrily at present ask Topic.
Invention content
The technical problems to be solved by the invention are to need offer one kind that can overcome data transmission in existing machine communication The problem of Reliability comparotive is poor, 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, include the following steps：
Step S1, the first communication node generation transmission data block, determines to transmit the biography according to the type of the transmission data block The corresponding reliability step information of transmission of data block, first communication node send the reliability step information and described first The location information of communication node gives the second communication node；
Step S2, second communication node generate the first configuration information according to the reliability step information, and by described the One configuration information is sent to first communication node, wherein, it is long that first configuration information includes at least the first frequency expansion sequence Degree and the first running time-frequency resource；
Step S3, after first communication node receives first configuration information, according to first spreading sequence length The first frequency expansion sequence is generated, and the transmission data block is sent on first running time-frequency resource；
Step S4, second communication node receive the transmission data by the half reception antenna in reception antenna set Block, if received successfully, the second communication node feedback reception successful information gives first communication node, and terminates； If reception failure, second communication node generates the second configuration information, and second configuration information is sent to institute The first communication node is stated, wherein, second configuration information includes at least the second spreading sequence length, the second running time-frequency resource and spy Reference signal transmission resources are surveyed, second running time-frequency resource is described by the first sub- running time-frequency resource and the second period of the day from 11 p.m. to 1 a.m frequency resource composition The carrier frequency of second sub- running time-frequency resource is higher than the carrier frequency of the described first sub- running time-frequency resource；
