Embodiment 1

[0036]The base station generates a data block containing 100 bits, the data block contains 16-bit redundancy check information, and the terminal trying to receive the data block must pass a check based on the redundancy check information to confirm whether it has successfully obtained the A data block, preferably, the data block is a coded bit stream obtained through physical layer coding.

[0037] The base station generates four first-type sub-data blocks each containing 25 bits and one second-type sub-data block with a length of 25 bits based on the data block. The first type of sub-data block is extracted from the data block at equal intervals, or sequentially selected from the starting position of the data block, as shown in the attached figure 2 As shown, each of the first type sub-data blocks includes part of the data block, the union of the four first sub-data blocks is equal to the data block, and the intersection is an empty set. as attached image 3 As shown, the ...

Embodiment 2

[0042] The base station receives the feedback information sent by the terminal, and the feedback information notifies the base station of a set of candidate transmission beams that can be used to transmit data to the terminal, the candidate transmission set includes 10 transmission beams and the corresponding reception quality of these transmission beams information.

[0043] The base station selects 4 transmission beams from the candidate transmission set to transmit data blocks to the terminal according to the rules agreed with the terminal, for example, selects the 4 transmission beams with the best reception quality, or selects according to a predetermined pattern.

[0044] The base station generates a data block containing 100 bits, the data block contains 16-bit redundancy check information, and the terminal trying to receive the data block must pass a check based on the redundancy check information to confirm whether it has successfully obtained the A data block, prefer...

Embodiment 3

[0051] The base station generates a data block containing 100 bits, the data block contains 16-bit redundancy check information, and the terminal trying to receive the data block must pass a check based on the redundancy check information to confirm whether it has successfully obtained the A data block, preferably, the data block is a coded bit stream obtained through physical layer coding.

[0052] The base station generates four first-type sub-data blocks each containing 25 bits and one second-type sub-data block with a length of 25 bits based on the data block. The first type of sub-data block is extracted from the data block at equal intervals, or sequentially selected from the starting position of the data block, as shown in the attached figure 2 As shown, each of the first type sub-data blocks includes part of the data block, the union of the four first sub-data blocks is equal to the data block, and the intersection is an empty set. as attached image 3 As shown, the...

Abstract

The invention provides a data transmission method of robustness. The method comprises the following steps: generating a data block with the length of X bit by a first communication node, wherein the data block comprises cyclic redundancy check information, and generating N first type sub-data blocks containing X / N bits through the data block, and then generating a second type sub-data block containing X / N bits through a counterpoint bit or XOR mode based on N first type sub-data blocks; respectively forming N transmission sub-data block groups through the N first type sub-data blocks and the second type sub-data block, and transmitting N sub-data block groups at N sending beams. The received second type sub-data block can be used for attempting to recovering the first type sub-data block in error. Through the adoption of the method, device and system provided by the invention, the robustness of the data transmission can be effectively increased to adapt to the service demand of the fifth generation wireless communication system in comparison with the prior art.

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...
