Problems solved by technology

Once the collusion is formed, the fairness of the auction will not be guaranteed, and the auction efficiency, system revenue and stability will also be affected
However, there is currently no research on collusion suppression in spectrum auctions in fractional frequency reuse scenarios

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] A method for suppressing collusion that exists when spectrum auctions are performed in a fractional frequency reuse scenario, comprising the following steps:

[0022] (1) Establish a system model for spectrum auction under fractional frequency reuse scenarios, such as figure 1 shown. Assuming that there are M spectrum owners with idle spectrum leased out as sellers, the spectrum resources they can contribute are represented by {s 1 ,s 2 ,...,s M} means that the reserve price set by sellers for all frequency bands in order to suppress bid ring collusion is denoted as {b 1 ,b 2 ,...,b M}, N sub-users with spectrum demands are spectrum auction buyers, and their bids for all frequenc...

Abstract

The invention discloses a method for suppressing collusion existing in spectrum auction under fractional frequency reuse scenarios. The method uses fractional frequency reuse technology to establish a system model, and according to factors such as channel state information, precoding, and transmission power, Determine the buyer's bid, and fully consider the collusion of the loser and the winner in the fractional frequency reuse technology, and propose a bid expression and a payment function expression with a collusion-inhibiting effect, and based on this Research on Spectrum Auction with the Objective of Maximizing System Utility. The method proposed by the invention is easy to implement, easy to expand, and closer to practical application. The spectrum auction method also has higher allocation efficiency and reuse efficiency, and the collusion suppression effect is obvious.

Description

technical field [0001] The invention belongs to the cognitive radio technology, in particular to a collusion suppression method for frequency spectrum auction under the scene of fractional frequency reuse. Background technique [0002] Due to the increasing shortage of spectrum resources and the unreasonable allocation of existing spectrum resources and the low efficiency of use, how to study more scientific and reasonable spectrum allocation and reuse methods has become an urgent problem to be solved. At present, the application of auction theory in the field of spectrum allocation has greatly improved the efficiency of spectrum allocation, and spectrum auction technology has become a research hotspot. Fractional frequency reuse technology becomes an efficient spectrum reuse method by dividing the cell into two parts, the center and the edge of the cell. This method provides different frequency bands for the center and edge users of the cell, and uses a certain reuse factor...
