Description
Technical field
The present invention relates to the communication technology more particularly to a kind of method for determining shared spectrum requirement and base stations.
Background technique
230MHz frequency range includes 223.025~235.000 total 12MHz bandwidth.It is at present that a frequency point is divided with 25kHz
Match, totally 480 frequency points, wherein nearly 100 frequency points via National Radio management board distribute to the energy, army, meteorology,
Totally 8 ministries and commissions use for shake, water conservancy, Di Kuang, light industry and construction, remaining 380 frequency point is by local radio administration according to industry
Demand is allocated.230MHz frequency range mainly uses the acquisition and transmission of narrowband data radio station system progress industry wireless data.
With the deep development of the industrial application of information technology, the broadband demand of industry wireless private network is increasingly enhanced, in 230MHz frequency
Section introduces spectrum-sharing techniques, and each sensory perceptual system is allowed rationally to occupy the authorization not used frequency of narrowband systems by fair competition
Spectrum, to meet the spectrum requirement and business demand of sensory perceptual system while ensureing the normal work of authorization narrowband systems.Sense
Know that system obtains authorization frequency point to radio regulatory organization application, be used for transmission broadcast, control information and ensure business；Dynamic Shen
It please obtain shared frequency spectrum and be used for transmission other non-guaranteed-services, avoid being perceived with narrowband systems with other in use process
The authorization frequency point of system.
For working in the electric system of 230MHz frequency range, 230 system of TD-LTE is for power industry customized development
Wireless Broadband Communication Systems, using narrowband resident technique support magnanimity terminal real-time online, meet system for distribution network of power automation,
The business demands such as load management, power information acquisition, emergency first-aid repair, special area video monitoring.The product is inheriting OFDM just
It hands over multi-subcarrier to transmit in the smaller advantage of intersymbol interference of unique channel relatively flat and channel, innovatively plays
Expansibility, frequency selectivity, dispatching flexibility of OFDMA system etc., and creative absorb carrier wave polymerization, frequency spectrum perception
Etc. advanced communication theory, the multi-business communication system of low-power consumption of new generation, high spectrum utilization, high reliability is constituted.
In spectrum-sharing techniques, sensory perceptual system rationally determines shared spectrum requirement, is had for justice using shared frequency spectrum
Important function.In existing method, one is determining spectrum requirement with system current demand signal amount of bandwidth, when not deposited in common spectrum
At the time of authoring system signal, and idle shared frequency range size meets unauthorized system signal current bandwidth, notifies base station pair
Unauthorized system carries out frequency handover.
Another program of the prior art is to increase to determine that frequency spectrum is needed with the terminal speed increase of base station service or terminal number
It asks, such as is sent out according to the increase of current data rate and handling capacity at one or more mobile stations of own base station service
It is raw, to maintain continuity or the company of service with certain service quality level with the agreement of one or more of mobile stations
The general character；And occurred according to the increase of the quantity of the active mobile stations of own base station service.
It is variant that the above method does not account for demand of the different service types to frequency band.All business, which can work, is awarding
Frequency spectrum is weighed, the only non-guaranteed-service in part can work in shared frequency spectrum, and by taking 230 system of TD-LTE as an example, power information is adopted
The business datums of less demanding to time delay such as collection can be in shared spectrum transmissions, the business datum to delay sensitive such as emergency first-aid repair
The a large amount of signalings that can only be generated in the transmission of authorization frequency point and random access procedure and/or attaching process must be in authorization frequency
Point transmission.So the demand of the terminal or terminal in different states of carrying different service types to shared frequency spectrum is different, no
Frequency spectrum only can be shared to judge that needs increase with terminal quantity or terminal speed increase.
