Embodiment Construction

[0134] The present invention is further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0135] The present invention considers a time-division multiplexing dual-layer heterogeneous cellular network system, in which the macro and micro cells are deployed in the same channel, and the macro and micro cells perform interference coordination through ABS subframes, that is, dynamic eICIC configuration ABS can be performed. The coordinated configuration may be done by a macro base station (eNodeB), where UE represents a user equipment (eg, a mobile terminal).

[0136] User model: For the user's downlink access, the UE can choose an access between the macro base station and the micro base station. The invention does not consider power control, assuming that the base station has the maximum transmit power, and the user determines the set of accessible candidate base stations according to the receive...

Abstract

The invention discloses an EE (Energy Efficiency)-eICIC-MaxMin method under time domain interference coordination. eICIC (Enhance Inter Cell Interference coordination) of a time domain is put forward in an isomeric cellular network, and the technical purpose is to keep silent in an Almost Blank Subframe to reduce the interference of a microcell or a femtocell through a macrocell. The densification deployment of the microcell or the femtocell has a higher requirement for the energy efficiency of the isomeric cellular network. According to the EE (Energy Efficiency)-eICIC-MaxMin method, the purposes of energy efficiency distribution of the Almost Blank Subframe on the time domain and energy efficiency accessing of user equipment on a space are achieved in a max-min fair perspective, the purposes are achieved in a distributed mode, and the EE (Energy Efficiency)-eICIC-MaxMin method is suitable for deploying a large-scale of dense microcells. As is shown by a numerical simulation result, the EE-eICIC-MaxMin method keeps good balance in the aspects of energy efficiency of systems and users, and the distributed algorithm has good convergence. The EE-eICIC-MaxMin method can be used for guaranteeing fair energy efficiency of users based on time domain interference coordination under an actual 5G isomeric cellular network.

Description

technical field [0001] The invention belongs to the technical field of mobile communication cellular networks, and in particular relates to a distributed energy efficiency optimization method with maximum and minimum fairness under time-domain interference coordination. Background technique [0002] Dense Heterogeneous Cellular Network (HetNet) architecture is an effective solution to meet the rapidly growing demand for wireless services, that is, deploying a large number of low-power nodes (eg, micro base stations or femto base stations) within a macro cell to form a heterogeneous dual-layer coverage. Due to power differences between base stations (BSs) in heterogeneous cellular networks, macrocells can cover a larger area than microcells, often resulting in overloaded macrocells with too few users in microcells. The capacity of the system can be increased by moving users to microcells, called load balancing. At the same time, user performance offloaded to microcells will ...
