Problems solved by technology

When the idle spectrum resources borrowed by SC1 for the reconfiguration node BS2 cannot meet the requirements of BS1 and BS2 to use the spectrum resources at the same time, it will cause interference between the two base stations
In severe cases, it may even lead to the problem that spectrum resources cannot be used
[0004] In addition, when the reconfiguration management nodes of multiple secondary systems compete for the idle spectrum resources of the primary system for their subordinate reconfiguration nodes, there is a problem of unreasonable allocation of idle spectrum resources. For example, suppose the secondary user equipment in secondary system A urgently needs The idle spectrum resources of the primary system are borrowed, and the spectrum resources of the secondary user equipment in the secondary system B are not very scarce (for example, the idle spectrum resources of the primary system are only used to enhance user experience), but the urgently needed spectrum resources of the secondary system A are borrowed. Due to the fact that there is no reasonable competition mechanism for idle spectrum resources, the spectrum allocation is unreasonable, which affects the reasonable operation of system services

[0072] image 3 A flow chart of the method for implementing the first embodiment of spectrum resource allocation for reconfiguration nodes in the present invention, as shown in image 3 As shown, in the first embodiment, assuming that the GLDB does not include information on borrowing idle spectrum resources from the secondary system to the primary system, the information on borrowing idle spectrum resources from each secondary system to the primary system is obtained through the sensing measurement method. When the reconfiguration node (BS1) under the secondary system needs to borrow the spectrum resources of the primary system due to business needs, BS1 sends a request to the reconfiguration management node (SC1) to borrow idle spectrum resources. It should be noted that each secondary system SC obtains the borrowing of idle spectrum resources of the primary system by subordinate secondary user equipment (including reconfiguration nodes and interference reconfiguration nodes...

[0085] Figure 4 A flow chart of the method for implementing the second embodiment of spectrum resource allocation for reconfiguration nodes in the present invention, as shown in Figure 4 As shown, when BS1 in the secondary system needs to borrow the spectrum resources of the primary system due to business needs, BS1 sends a request to SC1 to borrow idle spectrum resources. At this time, the GLDB does not contain information about borrowing idle spectrum resources by the interference reconfiguration management node.

[0086] In step 400, the SC1 to which the reconfiguration node BS1 belongs obtains the idle spectrum resource information of the primary system.

[0087] Table 2 is a list of free spectrum resource information. As shown in Table 2, the list of free spectrum resources indicates that the free spectrum (center frequency point) of the primary system is f1=512MHz, f2=542MHz, and f3=568MHz. The bandwidth is 6MHz. At the same time, GLDB provides the emission parameter...

[0095] Figure 5 The flow chart of the method for implementing the third embodiment of spectrum resource allocation for reconfiguration nodes in the present invention, as shown in Figure 5 As shown, in the third embodiment, it is assumed that the GLDB includes the idle spectrum resource information of the primary system and the borrowing information of the spectrum resource by the interfering reconfiguration node, so as to allocate the spectrum resource required by the reconfiguration node. When BS1 under the secondary system needs to borrow spectrum resources of the primary system due to service requirements, BS1 sends a request to SC1 to borrow idle spectrum resources.

[0096] In step 500, the SC1 to which the reconfiguration node BS1 belongs obtains the idle spectrum resource information of the primary system and the borrowing information of the idle spectrum resource by the interference reconfiguration management node.

Abstract

A method and device for allocation of frequency spectrum resources, said method comprising: when a reconfiguration node needs to borrow frequency spectrum resources from a main system, a reconfiguration management node belonging to the reconfiguration node acquires information about idle frequency spectrum resources of said main system, as well as information about the borrowing by other interfering reconfiguration management nodes with respect to the idle frequency spectrum resource of said main system; on the basis of said borrowing information, the reconfiguration management node determines the idle frequency spectrum resources which are available to the reconfiguration node, and allocates said resources to said reconfiguration node.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for realizing frequency spectrum resource allocation. Background technique [0002] The continuous progress of radio technology promotes the emergence of more radio services. However, radio services rely on limited spectrum resources, making the problem of spectrum resource shortage gradually appear. The traditional fixed spectrum allocation mode makes some spectrum resources not fully utilized, resulting in a low overall utilization rate of spectrum resources, and there is a large degree of available idle spectrum. For example, some radio and television system spectrum resources are not used in certain regions; or, although some radio and television system spectrum is covered in a certain region, it is not used in certain time periods. In order to enable these unused spectrum resources to be reused, cognitive radio technology (IMT) breaks the pattern o...
