Intelligent interference management in 5G wireless networks by Jiandong LI, Lei LIU, Min SHENG, UChao X

“…As one of the key technologies in 5G networks，ultra-dense wireless network is utilized to approach the future 1 000 ultra-high traffic volume.Nevertheless，the dense deployment of network nodes would result in severe interference，and thus interference management was proposed as the big principle behind 5G ultra-dense wireless networks research.Firstly，the interference management schemes were classifed from two aspects：avoidance and utilization.Then，an intelligent interference management architecture was proposed to accommodate the development trend of future wireless networks in terms of intelligence and heterogeneity in order to realize the dynamic tightly coupled interference management of wireless network environment and interference management.Taking the intrinsic relationship between interference management and resource management into consideration，three cutting-edge interference management schemes were introduced，which could significantly improve the network resource utilization and the network capacity.…”

Improved cell search algorithm for 5G NR by Baojiang DONG, Chen PENG, He LU

“…The era of 5G NR has higher requirements for speed, capacity and user experience.In 5G NR physical layer, cell search is an indispensable process.Cell search mainly includes primary synchronization signal (PSS) detection algorithm and secondary synchronization signal (SSS) detection algorithm.The traditional PSS detection algorithm and SSS detection algorithm can’t satisfy the basic requirements of 5G NR.In order to solve this problem, an improved PSS detection algorithm based on the traditional M-segment cross-correlation detection algorithm was proposed.When the channel environment is bad, the traditional SSS detection algorithm will also fail.The improved SSS detection algorithm proposed can solve this problem.Finally, the traditional algorithm and the improved algorithm were compared and analyzed.The simulation results show that the detection performance of the proposed algorithm is significantly improved, and the detection efficiency and overall performance are also improved.…”

5G network slicing algorithm based on prediction by Jiageng ZHANG, Min ZHU, Feng DU, Qi WANG, Jun LIU, Zhihai SUO, Li WANG

“…5G on line scenario needs short build time of network slice, it can use prediction algorithm to isolate network resource in advance to reduce the construction time of network slice.A 5G network slicing algorithm based on prediction was proposed, which used fourth square as cost function to predict the network resource requests with accepted accurate and lower complexity of algorithm.And then based on the prediction result, virtual nodes and links resource were allocated, and container was pulled up when network slice request arrives to network, the dynamic creation of network slices was completed.The simulation results show that the proposed algorithm can get 90% accurate of prediction, and reduce 50% construction time of network slice, and improve the network utilization ration，when new network slice reusing the original network slice.…”
