Embodiment Construction
[0042] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0043] As described in the background art, auction theory is widely used in dynamic spectrum allocation, and the use of auction theory to solve the allocation of spectrum resources in wireless communication networks has excellent characteristics that cannot be possessed by general methods. Moreover, through a reasonable design of the auction mechanism, on the one hand, the income of the main user or the secondary user can be improved or even maximized; Multi-user dynamic allocation of spectrum res...

The invention relates to a method for distributing frequency spectrum resources in the cognitive network in the technical field of communication. The method for distributing frequency spectrum resources in the cognitive network includes steps of acquiring the number of idle time frequency unit blocks, transmitting broadcast information which comprises the number of the idle time frequency unit blocks to secondary users; acquiring selection information which comprises the number of the time frequency unit blocks applied by the secondary users and total charges of the time frequency unit blocks and is fed back by the secondary users; selecting norm of each secondary user on the basis of selection information, and relating the norms to the selection information; and determining the secondary users acquiring the frequency spectrum resources according to the sequence of the norms of the secondary users from large to small. By the method for distributing frequency spectrum resources, total gains of the secondary users are increased, operation complexity in the distributing process of the frequency spectrum resources is reduced, and utilization rate of the frequency spectrum is increased to a great extent.
Description
technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for allocating frequency spectrum resources in a cognitive network. Background technique [0002] With the rapid development of wireless services, spectrum resources have gradually become a scarce resource. Almost all available frequency bands have been allocated for use by relevant services. However, a large number of measurements have found that a considerable part of the licensed spectrum is unused or infrequently used, and the utilization rate of wireless spectrum resources is very low. Just like this, Cognitive Radio (CR, CognitiveRadio) technology was proposed to solve the low utilization rate of current wireless spectrum resources, and also make spectrum allocation very flexible. [0003] Cognitive radio, also known as smart radio, is a technology that dynamically perceives idle spectrum and allocates and utilizes it. Its core goal is to change...
