Abstract

The invention provides an improved data transmission method comprising the following steps: a first communication node allocates a first sending resource and a second sending resource for a second communication node; the second communication node generates a to-be-transmitted data bit block which contains cyclic redundancy check information and of which the length is Y; the second communication node has three candidate demodulation reference signal transmission modes; the first communication node receives a demodulation reference signal on the first sending resource, determines the transmission mode of the demodulation reference signal, and feeds a message about reception success or failure back to the second communication node; after receiving reception failure information fed back by the first communication node, the second communication node generates a retransmitted redundant data bit block, and sends the retransmitted redundant data bit block on a third sending source allocated by the first communication node for the second communication node; and the first communication node processes the received retransmitted redundant data bit block and the previously-received to-be-transmitted data bit block. By using the method, the robustness of data transmission can be increased effectively to adapt to the service need of the fifth-generation wireless communication system.

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 growth of 1.6 to 2 times, which puts 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 the diver...
