Problems solved by technology

[0010] The purpose of the present invention is to provide a spectrum concession method, a spectrum occupation method and a device to solve the problem that the current CR system cannot work normally due to interference on the occupied spectrum resources, and how to solve the problem when the current CR system needs to withdraw the spectrum but cannot Avoid interfering with collisions, etc.

Embodiment Construction

[0088] Before describing the embodiments of the present invention in detail, the concepts involved in the embodiments of the present invention will be described first.

[0089] The CR system that is occupying spectrum resources is called the current CR system.

[0090] The spectrum resource occupied by the CR system is called the working spectrum.

[0091] The CR system that needs to occupy the working spectrum of the current CR system is called a replacement CR system.

[0092] For example, in the above method 2 for accessing spectrum, the CR system that is occupying spectrum resources is the current CR system, and the CR system that will occupy the working spectrum of the current CR system in method 2 is the replacement CR system.

[0093] For example, in the third access spectrum mode above, CR system 1 uses spectrum resources in time window 1, and CR system 2 uses spectrum resources in time window 2. If CR system 1 is the current CR system, and CR system 1 ends in time w...

Abstract

The invention discloses a frequency spectrum conceding method, a frequency spectrum occupying method and a device. The frequency spectrum conceding method comprises the steps of sending a negotiation process for delaying conceding a work frequency spectrum to a replacing CR system when a current CR system can not continuously occupy the work frequency spectrum is determined, and conceding the work frequency spectrum after the delayed time determined by the negotiation process. The provided technical scheme is introduced to the negotiation process for delaying conceding the work frequency spectrum, the current CR system concedes the work frequency spectrum according to the delayed time determined by the negotiation process, the fact that the current CR system and the replacing CR system both can not normally work is avoided, and the utilization efficiency of the frequency spectrum is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a spectrum concession method, a spectrum occupation method and a device. Background technique [0002] Radio communication spectrum is a precious natural resource. With the rapid development of wireless communication technology, the problem of poor spectrum resources is becoming more and more serious. In order to alleviate the shortage of spectrum resources, relevant departments and institutions have carried out monitoring and research on radio communication spectrum , it is found that some frequency bands (such as TV frequency bands) are not used most of the time or in most regions, while some frequency bands have the situation of multi-system and multi-user competition at the same time. That is, some systems with a large service carrying capacity do not have enough spectrum resources, while other systems with a small service carrying capacity occupy too man...
