Abstract

The present invention provides a flexible data transmission method, comprising that the first node allocates the first shared transmission resource divided into first and second sub-transmission resources in time for the second node; Randomly select a spread spectrum codeword A in the set, and select a set of spread spectrum codeword subsets containing X spread spectrum codewords from the second spread spectrum codeword set according to A; the second node transmits A in the first sub-transmission resource , using the spreading codeword on the second sub-transmission resource to spread the Y-bit data to be transmitted and then transmit it; the first node uses the channel information and the spreading codeword subset to decode the Y-bit data; if the second node No ACK is sent Z times on the first shared resource, then the second node sends a link abnormal spread code word on the link abnormal information resource; the first node measures the received link abnormal spread code word Energy value, perform follow-up operations according to the energy value. The invention can effectively increase the robustness of data transmission.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data transmission method in the fifth generation wireless communication system. Background technique [0002] With the rise of smart terminals and the enrichment of wireless data application services, the number of data users in wireless communication systems has increased significantly, and data content is no longer limited to traditional text or images. The demand is increasing, leading to the explosive growth of wireless network traffic. According to market forecasts, in the next 10 years, wireless data services will increase by 500 to 1,000 times, with an average annual increase of 1.6 to 2 times, which puts forward higher requirements on the network capacity of wireless communication systems. [0003] Facing 2020 and the future, mobile Internet and Internet of Things services will become the main driving force for the development of mobile communications. 5G will meet...
