Distributed energy-saving resource distribution method of heterogeneous network

Abstract

The invention discloses a distributed energy-saving resource distribution method of a heterogeneous network, and belongs to the technical field of heterogeneous network self-organizing network. The method comprises the following steps: a home base station in a residential quarter obtaining a corresponding adjacent jamming list according to a jammed condition of all users; the home base station in the residential quarter obtaining an initial sub-channel allocation according to a new utility function; the home base station in the residential quarter performing cooperative sub-channel allocation to the determined initial sub-channel allocation based on respective adjacent jamming list; the home base station in the residential quarter performing power allocation according to new utility function after determining the sub-channel allocation, and a macro base station performing non-uniform pricing on each sub-channel. The same-layer jamming between the home base stations can be effectively reduced, the QoS requirement of a macro user on each sub-channel can be effectively guaranteed, thereby effectively reducing the cross-layer jamming of the home base station to the macro user.

Description

technical field

[0001] The invention belongs to the technical field of self-organizing networks of heterogeneous networks, and relates to a distributed energy-saving resource allocation method of heterogeneous networks. Background technique

[0002] In order to meet the demand for ever-increasing data transmission rate and greater coverage, under the requirement of constantly improving network performance, a heterogeneous network (Heterogeneous Network, Hetnet) technology emerges as the times require. There are many different types of network nodes in the heterogeneous network. Different from the traditional single-layer cellular network, the inter-layer interference and intra-layer interference in the heterogeneous network bring greater challenges. In a traditional network deployed by an operator, such as a macro cell and a relay, interference can be eliminated through a frequency reuse scheme (for example, frequency planning of a relay link and a direct link). However, th...

[0036] figure 1 As the overall flowchart of this method, it can be seen from the figure that this method can be divided into 4 major steps, namely:

[0037] Step A, set the system mode.

[0038] Step B, obtaining the neighbor interference list AIL information of each home base station in the cell.

[0039] Step C, according to the proposed method, each home base station performs preliminary sub-channel allocation.

[0040] In step D, the cooperative sub-channel allocation is performed again among the home base stations.

[0041] Step F, perform power allocation according to the spectrum allocation result.

[0042] The specific process of each step is described in detail below.

[0043] Step A - Set the system mode.
