Analysis of Optimization Strategy for Carrier Aggregation Multi-Frequency Cooperative Networking
At present,5G networks have been widely commercialized.To improve coverage and downlink speed,and improve user experience,the Carrier Aggregation(CA)is introduced in 3rd Generation Partnership Project(3GPP)to aggregate multiple contiguous or non-contiguous CA into a larger bandwidth to meet the requirements of commercial wireless networks.CA can make full use of operators'non-contiguous spectrum resources and im-prove the utilization of discrete spectrum resources.In 5G SA networking,especially in a large-scale co-construction and sharing environment of an operator,CA can make full use of spectrum resources of all parties to aggregate into a larger bandwidth,so as to achieve excellent user experience,establish a competitive advantage,and effectively expand a coverage range by using a combination of a high frequency and a low frequency,thereby allevi-ating a coverage bottleneck problem.
