Embodiment
[0040] Reference figure 1 , A variable-step step-by-step spectrum auction method for femtocell base stations in a two-layer heterogeneous network, including the following steps:
[0041] 1) Establish a spectrum auction model: such as figure 2 As shown, the spectrum auction model is a system model based on a two-layer heterogeneous network. The seller is a plurality of authorized users with multiple non-overlapping and indivisible free frequency bands, and the nature of these frequency bands is bandwidth and modulation mode. It’s exactly the same. The sellers hand their free frequency bands to the auctioneer’s central processor and place them in the spectrum pool of the secondary market for auction. The buyer obtains free licensed spectrum by bidding on the selling price and acts as a wireless link for unlicensed The femto base station that the user provides communication services. Each femto base station only cares about whether it obtains the spectrum in the spectrum pool and ...

The invention discloses a variable step stepping-type frequency spectrum auction method for femtocell base stations in a two-layer heterogeneous network. The method is characterized by comprising the following steps: 1) a frequency spectrum auction model is built; 2) femtocell base stations are deployed and a two-layer heterogeneous network is constructed; 3) an authorized user gives m idle frequency bands to a central processing unit for bid auction; 4) detection turn auction is started; 5) the central processing unit sets a step; 6) a real auction turn is started; 7) the femtocell base station evaluates the bid of an auctioneer; 8) the central processing unit counts the number n of femtocell base stations sending an auction request; and 9) the central processing unit judges whether demands on the idle frequency bands by the femtocell base stations are surplus. The variable step stepping-type auction is higher in auction efficiency, profits of the authorized user are further improved, effective sharing and dynamic management on frequency spectrum resources are realized, and the problem of low frequency spectrum efficiency is solved fundamentally.
Description
Technical field [0001] The invention relates to the technical field of wireless communication, in particular to a variable step-length step-by-step spectrum auction method for femtocell base stations in a double-layer heterogeneous network. Background technique [0002] With the rapid development of wireless communication technology and mobile Internet, wireless data traffic has soared at an alarming rate. The survey shows that: more than 60% of voice services and 90% of data services occur indoors, and this proportion continues to increase. Therefore, it is becoming more and more important to provide high-speed and high-quality coverage services for indoor users' voice and data services. Femtocell BS, as a wireless access technology that can effectively enhance indoor coverage and increase network capacity, has received high attention from the communications industry and has become a research hotspot in mobile communications networks of different standards. Femtocell base stat...
