Self-backhauling resource allocation method in ultra-intensive heterogeneous network

Abstract

The embodiment of the invention provides a self-backhauling resource allocation method in an ultra-intensive heterogeneous network. The self-backhauling resource allocation method comprises the stepsof: according to a set relationship between a backhauling rate corresponding to a base station n in a macro base station and an access rate of the micro base station, obtaining a time division block factor value of a backhauling link corresponding to the micro base station n; according to a proportional fair algorithm, calculating an average allocation rate (with reference to the specification) ofall allocation time slots corresponding to the micro base station n at a t-1 moment before a current t moment; according to the time division block factor value of the micro base station n, the average allocation rate (with reference to the specification) of all the allocation time slots corresponding to the t-1 moment and a user number Fn corresponding to the micro base station n, calculating achannel allocation priority corresponding to the micro base station n; and according to the channel allocation priority, carrying out backhauling resource allocation on the micro base station. By applying the self-backhauling resource allocation method provided by the embodiment of the invention, improvement on throughput of the micro base station is implemented; in the process of allocating backhauling resources, fairness is shown; and in the backhauling resource allocation process, an operation with high complexity is avoided.

Description

technical field [0001] The invention relates to the technical field of self-backhaul resource allocation of a base station, in particular to a self-backhaul resource allocation method in an ultra-dense heterogeneous network. Background technique [0002] The macro base station is a public mobile communication base station, which is a traditional form of radio station. It refers to a radio transceiver station that transmits information between a mobile communication switching center and a mobile phone terminal in a certain radio coverage area. In an ultra-dense heterogeneous network, a macro base station covers the entire area, and there are multiple micro base stations and many users. Users can be divided into macro base station users and micro base station users. The backhaul network between the micro base station and the macro base station uses self-backhaul technology, while the backhaul between the macro base station and the core network uses wired transmission methods s...
