Frequency spectrum auction method of two-layer heterogeneous network containing small cells

Abstract

The invention provides a frequency spectrum auction method of a two-layer heterogeneous network containing small cells. In combination with a macro cellular network and numerous small cells within a radiation range, a frequency spectrum allocation auction model is established to divide an authorized frequency band provided by a macro base station into a plurality of time slots for auction as commodities, a user return function is set, an auction target function is established according to auction bid, and a maximum return slot allocation method is obtained through the optimization theory according to the bid. The frequency spectrum allocation auction model is auction technology based on a VCG mechanism that performs allocation by dividing the time slots. The frequency spectrum auction method has the beneficial technical effects as follows: (1) the auction mode is used for resource allocation; 2) the frequency spectrum resource is divided into time slots; and 3) the user bits are associated with the gains obtained by the small cells by purchasing the frequency band communication. By adoption of the frequency spectrum auction method provided by the invention, the effective allocation of the mobile communication resources is realized, an excellent frequency spectrum resource allocation mechanism is provided, the utilization efficiency of the spectrum resources is improved, and thus the application prospect is broad.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a spectrum auction method of a two-layer heterogeneous network including small cells. [0002] technical background [0003] Nowadays, more and more users rely on mobile communication. With the vigorous development of wireless communication, mobile communication has become an indispensable part of people's daily life. Correspondingly, the number of mobile terminals and the user's demand for spectrum resources also show a large increase. LTE-A, the upgraded version of the fastest commercial mobile communication technology, also has to face new challenges. In order to cope with the ever-increasing demand of mobile communication users, communication operators and equipment manufacturers will set up small cells. Set up multiple small cells under the macro cell to form a two-layer heterogeneous network as a solution to improve system capacity. [0004] A small cell is a...

Problems solved by technology

[0008] 1) The existing auction allocation process stays in the static auction stage, and the auction allocation process tends to compare bids for direct allocation, without an obvious bidding process

[0009] 2) Most of the spectrum allocation methods of the same type adopt the method of frequency division multiplexing. Multiple users use the same frequency band after bidding. There is interference between users and the signal-to-interference ratio is not guaranteed, and the communication quality of users cannot be guaranteed.

[0010] 3) The existing spectrum auction method does not link user bids with the benefits obtained by small cells from purchasing frequency band communications
