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) of each system , and 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

Disclosed are a spectrum coordination device and method, and a device and method in a wireless communication system. The spectrum coordination device is used to coordinate the use of shared wireless transmission resources by multiple systems, which includes: an acquisition unit configured to acquire shared wireless transmission resources A usage state of the resource; and an allocation unit configured to allocate shared wireless transmission for the communication device based on the impact of the resource element to be allocated in one of the multiple systems on the available resource elements of other systems in the multiple systems according to the usage state Resources, where the resource allocation granularity of one system is finer than that of other systems. According to the embodiments of the present disclosure, use of shared wireless transmission resources by multiple systems using different wireless access technologies can be effectively coordinated, resource utilization efficiency is improved, and system performance is optimized.
Description
Technical field [0001] The present disclosure relates to the field of wireless communication technology, and more specifically, 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 wireless communication in this case. Device and method in communication system. Background technique [0002] With the rapid development of computer and communication technology, 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. The traditional exclusive spectrum usage proved to be an inefficient way of resource usage. As more and more new spectrum resources are released from the original services, they become dynamic access resources that can be shared by multiple systems, mak...
