Description

Spectrum resource allocation method, device and system
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for spectrum resource allocation.
Background
With the continuous progress of radio technology, various radio services emerge in large quantities, and the frequency spectrum resources supported by the radio services are limited, so that the frequency spectrum resources show a very nervous situation in the face of the continuous increase of bandwidth requirements of people; on the other hand, under the conventional fixed spectrum allocation mode, the utilization rate of the spectrum resources is not high. In a sense, the spectrum allocation system fixedly allocated to the authorized system causes a situation of extremely tight spectrum resources. The cognitive radio technology breaks through a traditional spectrum fixed allocation system, dynamically allocates the spectrum among systems, and improves the utilization efficiency of the spectrum. Typically, as the daily communication demand of people is continuously increased and is not satisfied with simple voice data communication, the proportion of video streaming media service in the communication life of people is continuously increased, which requires a larger bandwidth as a support, the International Mobile Telephone (IMT) system shows an unprecedented spectrum tension, and for the broadcast television system, there is available space for the spectrum resources to a great extent, for example, the spectrum of some broadcast television systems is not used in some regions; although some broadcast television system frequency spectrums are covered in a certain area, the frequency spectrums are not used at certain time, and the overall utilization rate is low. The fixed spectrum allocation makes the unused spectrum resources unavailable for reuse, for example, for use by the IMT system. By acquiring the information of the broadcast television system, the IMT system based on the cognitive radio technology opportunistically occupies unused spectrum resources (TVWS) of the broadcast television system in space and time, thereby improving the utilization rate of the spectrum of the broadcast television system and improving the situation of spectrum shortage of the IMT system.
The spectrum using mode that the secondary system opportunistically occupies the spectrum resource of the primary system must ensure that the primary user is effectively protected, namely, when the secondary system uses the spectrum resource of the primary system, harmful interference can not be caused to the user of the primary system, which is a precondition for realizing the cognitive radio technology. In order to achieve such an objective, firstly, the used spectrum and transmission parameters of the secondary system are limited by the protection requirements of the primary system, and an accurate decision needs to be made when the parameters are initially determined; secondly, the secondary system needs to know the occurrence of the primary user in time, so that the secondary system can quit the spectrum resource in time when finding out that the primary user on the spectrum resource occupied by the secondary system occurs again, and the interference to the primary user is avoided.
Further, since there may be a plurality of secondary ues using the primary system white space at the same time, another necessary condition that the TVWS can be used is that the secondary systems can coexist on the TVWS, and use the TVWS resources without interfering with each other, that is, the mutual interference is within a tolerance range. Therefore, interference avoidance between secondary systems is also a factor that must be considered in spectrum resource allocation decisions.
In the discussion of ETSI RRS in the current standards organization, a TV band Cognitive Radio (CR) technology system architecture is as shown in fig. 1, in which:
the geographic location information Database (GLDB) is responsible for protecting the primary system, and provides the primary system spectrum usage for the secondary user equipment or the secondary system management node, thereby preventing the primary system from being interfered by the secondary system. Specifically, idle spectrum resources at the position of the secondary user equipment are provided for the secondary user equipment, and the maximum transmitting power allowed by the secondary user equipment is calculated according to the protection criterion of the primary user;
a Spectrum Controller (SC) is a secondary system Spectrum resource reconfiguration management node, and is responsible for coexistence management, priority management, and measurement management among secondary ues. Two modes are adopted: the system is responsible for coexistence solution and spectrum allocation among subordinate secondary user equipment in a management mode; and the information mode is responsible for providing coexistence environment information required for coexistence solution to subordinate secondary user equipment.
A Cognitive System (CRS) is a secondary System, and includes several secondary user equipments (WSDs); it may represent a cellular Network system Network such as a Long term evolution (Long term evolution, abbreviated as LTE), a 3G system, a 2G system, or an IEEE802 system Network such as a Wireless Local Area Network (WLAN), a Wireless local Area Network (WRAN), a Worldwide Interoperability for Microwave Access (Wimax), and the like, and a base station in the cellular system or an Access point in the IEEE system is specifically used in the CRS to interact with an upper node (GLDB/SC).
The architecture comprises two main types of CRSs, one type of CRS is directly connected with the GLDB and is called as a non-coordinated CRS, namely coexistence among the CRSs does not need participation of a management node SC, and the problem is solved through a self-coexistence mechanism of a network; the other type is indirectly connected with the GLDB through the SC, the coexistence among the secondary system devices cannot be solved by the SC, and the operation parameters (management mode) of the secondary user devices are determined through the assistance of the SC, namely, the SC is required to uniformly manage the coexistence among the subordinate secondary user devices; or the SC provides the coexistence environment information required for coexistence to the secondary user equipment, and the secondary user equipment decides an operation parameter (information mode) satisfying the coexistence requirement. As can be seen from the above scheme, coexistence between the secondary ues in the uncoordinated CRS can be achieved, and coexistence between the secondary ues in the coordinated CRS can also be achieved. For coexistence between non-coordinated CRS subordinate secondary user equipment and coordinated CRS subordinate secondary user equipment, additional consideration is needed.
In the related art, interference between uncoordinated secondary user equipment and coordinated secondary user equipment is not considered, which causes malicious competition of two types of secondary user equipment on idle spectrum resources, affects network performance, reduces spectrum efficiency, even makes the originally idle spectrum resources unusable, and deviates from the original intention of cognitive radio technology.
For the problem that interference between non-coordinated secondary user equipment and coordinated secondary user equipment is not considered in the related art, no effective solution is proposed at present.

The architecture comprises two main types of CRSs, one type of CRS is directly connected with the GLDB and is called as a non-coordinated CRS (wherein specific user equipment is called as non-coordinated secondary user equipment), namely the coexistence between the CRSs does not need the parameters of a management node SC, and the problem is solved through a self-coexistence mechanism of a network; another type is indirectly connected with GLDB through SC, called coordinated CRS (where a specific user equipment is called coordinated secondary user equipment), and this type of coexistence between secondary system equipments cannot be solved by itself, but needs assistance through SC; further, the coordinated CRS is divided into two service modes, a management mode: the SC is responsible for coexistence solution and frequency spectrum allocation among subordinate secondary user equipment; information mode: the SC is responsible for providing information required for coexistence solution to subordinate secondary user equipments, and the secondary user equipments determine operating spectrum and configuration parameters themselves.
