Problems solved by technology

[0011] Because after analyzing the information reported by the data source, the channel occupancy situation in the coverage area of ​​the cognitive system is obtained, and then spectrum holes are found. However, in the prior art, only one channel state is stored for a channel, and this state is maintained. But in fact, due to the difference in geographical location of the occupancy sources, a channel is likely to be occupied by multiple occupancy sources at the same time, which leads to an incomplete understanding of the occupancy of the channel by the system. For example, channel K is occupied by two occupancy sources, one is One is

Abstract

An embodiment of the invention discloses a method for collocating channel state of cognitive system, a detection management device and a base station. The method of the invention comprises the following steps: obtaining data information reported by the data source; analyzing the channel state of channel according to the data information reported by the data source; and if a plurality of channel states of a same channel obtained by analyzing are obtained, storing the plurality of channel states for the channel. Because when the plurality of states exist in the channel, the existing states are saved and the actual state of empty-opening channel is actually reflected. Compared with the prior art, the states of mutual signal interference and further the interference to the authorized subscriber, which are caused by no saving of the plurality of channel states, are effectively prevented. The allocation of empty-opening resource is caused to more reasonably.

Description

technical field [0001] The present invention relates to cognitive radio technology, in particular to a cognitive system channel state configuration method, a detection management device and a base station. Background technique [0002] Cognitive radio technology is a technology that realizes efficient and flexible use of spectrum holes without interfering with authorized users. A spectrum hole is an unoccupied frequency band in a certain time and space. Due to the scarcity of radio resources and the low utilization rate of authorized frequency bands, cognitive radio technology has received extensive attention in academia and industry. [0003] The premise of the cognitive system is to be able to obtain the spectrum usage and be able to find the spectrum holes in it. The cognitive system provides a variety of data sources in order to realize the correct recognition of the spectrum. By analyzing the channel state information reported by the data sources, the spectrum holes i...
