Different from 4 G network capability based on downlink

the business characteristics in the 5 G are changing.With the high-definition of live broadcast business and the rise of a series of 5 G basic businesses such as wireless video monitoring applications

higher requirements are put forward for uplink capabilities.Based on the current status of 5 G frequency resources

this paper briefly describes several multi-frequency coordination technologies based on the 5 G R16 version

analyzes the network performance and the problems in the network.This paper also proposes strategy recommendations for selecting multi-frequency coordination technologies in actual networking

to give the advantages of each frequency band to enhance uplink capacities

maximize resource efficiency

and create differentiated competitive advantages.
