Problems solved by technology

However, the problem of using this carrier aggregation technology is that the premise that the scattered spectrum used is idle must be satisfied, and the interference problem after carrier aggregation is also a problem that needs to be solved urgently
The issues that need to be addressed for dynamic spectrum sharing are not currently being implemented

Abstract

The invention discloses a system for sharing a dynamic frequency spectrum. A DFPA (Dynamic Frequency Planning Adjustment) unit is used for planning and configuring available frequency spectrum resources to a plurality of wireless systems. The invention further discloses a method for sharing the dynamic frequency spectrum. When the sharing of the dynamic frequency spectrum is started and after the DFPA unit receives information of starting the sharing of the dynamic frequency spectrum, relevant frequency spectrum information is transmitted to DFRD (Dynamic Frequency Reframing Decision) units residing on different wireless systems; and after the DFRD units receive the relevant frequency spectrum information, the available frequency spectrum resources of the wireless network are determined. The system and the method which are disclosed by the invention are used for dynamically sharing wireless frequency spectrum resources under the condition that the wireless systems coexist, therefore, the wireless frequency spectrum can be shared more effectively and flexibly, the utilization rate of network resources is improved and the user experience is improved.

Description

technical field [0001] The present invention relates to spectrum sharing technology, in particular to a dynamic spectrum sharing system and method for dynamically sharing wireless spectrum resources between different wireless systems. Background technique [0002] Striving for greater bandwidth and greater throughput is one of the driving forces for the development of new technologies. However, with the gradual evolution of various wireless technologies, the lack of spectrum has become a bottleneck in the development of wireless technologies. [0003] At the same time, with the continuous development and maturity of new technologies, the coexistence of new systems and old systems, and gradual replacement has become the norm. Under such circumstances, how to effectively and smoothly utilize the original spectrum resources has also become a research hotspot. [0004] In terms of research on the effective use of spectrum resources, various wireless technologies are brilliant, ...
