Problems solved by technology

However, due to the fixed spectrum allocation system in the traditional mode, the scarce spectrum resources are idle most of the time, resulting in a large waste of spectrum resources, resulting in extremely limited spectrum resources allocated to small cells, which limits the use of small cells to optimize network coverage.

Embodiment

[0047] A spectrum auction method for a small cell, comprising the steps of:

[0048] 1) Establish a system model of small cell spectrum auction. These include authorized users with multiple non-overlapping and indivisible free frequency bands; various mobile terminals that require spectrum resources; small cells that obtain spectrum resources through auction and serve mobile terminals; and central spectrum auction processing as an auction hub device.

[0049] 2) Assuming that authorized users as sellers own M licensed frequency bands, denoted as α={1, 2, ..., M}, there are N small cells as buyer sets, denoted as β = {1, 2, ..., N}. When the auction starts, the central spectrum auction processor announces the auction information of the M licensed frequency bands.

[0050] 3) There is interference between small cells, and an N*N interference matrix is ​​established according to factors such as distance

[0051] B={b ij} N×N ,b ij ∈{0,1},i∈β,j∈β (1)

[0052] where B is the...

Abstract

The invention discloses a small cell spectrum auction method. According to the method, small cells and spectrum auction are combined, the small cells are deployed to borders of macrocells, campuses, offices, markets and other regions where coverage of macro-sites is weak or users are populated densely and rooms, idle authorized frequency bands are acquired through the auction method, spectrum resources are effectively allocated to the small cells, the advantage that the small cells optimize network coverage is given full play, and effective sharing and dynamic management of the spectrum resources are achieved. The purposes of indoor coverage, hotspot coverage, deep coverage and the like of mobile communication networks are achieved, the defects of macro-honeycombs are overcome, the spectrum efficiency is improved, and high-speed wireless services are provided for nearby users.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a small cell spectrum auction method. Background technique [0002] With the rapid development of mobile communication systems, the number of mobile broadband users is increasing rapidly, in which, for example, mobile terminals such as smart phones emerge in large numbers. Various limitations of traditional macro cells are increasingly manifested in meeting the requirements of LTE mobile broadband communication. In this context, the concept of small cells is proposed as an effective means to solve the above problems. A small cell is a base station device with low transmission power and small-scale coverage. As a supplement to 3 / 4G macro cells, it has the advantages of flexible and rapid deployment, and can effectively solve network coverage problems in hotspot absorption, blind spots, and weak coverage scenarios. It enables operators to provide users with...
