Spectrum coordination apparatus, spectrum coordination method, apparatus and method in wireless communication system

Abstract

The invention discloses a spectrum coordination apparatus, a spectrum coordination method as well as an apparatus and method in a wireless communication system. The spectrum coordination apparatus is used for coordinating the use of shared wireless transmission resources by a plurality of systems. The spectrum coordination apparatus comprises an acquisition unit which is configured to acquire the use state of the shared wireless transmission resources, and an allocation unit which is configured to allocate the shared wireless transmission resources to communication devices based on the influence of resource particles to be allocated of one of the plurality of systems on the available resource particles of the other systems in the plurality of systems and according to the use state, wherein the resource allocation granularity of the one system is smaller than the resource allocation granularity of the other systems. With the spectrum coordination apparatus, the spectrum coordination method as well as the apparatus and method in the wireless communication system provided by the embodiments of the invention adopted, the use of the shared wireless transmission resources by the plurality of systems which use different wireless access technologies can be effectively coordinated, and therefore, resource utilization efficiency can be improved, and the performance of the system can be optimized.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and more particularly, to a spectrum coordination device and a spectrum coordination method for effectively coordinating the use of shared wireless transmission resources by multiple systems with different resource allocation granularities, and the wireless communication system in this case. Apparatus and method in a communication system. Background technique [0002] With the rapid development of computer and communication technologies, the number of user equipment, service requirements, and usage scenarios will increase exponentially, further intensifying the contradiction between wireless service requirements and wireless spectrum resources. Traditional exclusive use of spectrum has been proven to be an inefficient use of resources. As more and more new spectrum resources are released from original services, they become dynamic access resources that can be shared by mu...

Problems solved by technology

[0003] Although the resource sharing of multiple systems provides the possibility to increase the system capacity from the perspective of increasing the available spectrum, the coexistence of multiple systems results in differences in spectrum division and use methods due to the differences in the RAT (Radio Access Technology, Radio Access Technology) of each system. At the same time, these wireless access technologies also have different priorities for the use of spectrum

At present, there is no technology to coordinate the differences in the use of shared frequency bands of different RATs to improve the access capacity of shared spectrums to users of different RATs and to ensure the priority of use, which will lead to inefficient use of shared frequency bands, and even destroy the RATs with different priorities. The right to use this frequency band
