Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing:
[0033] figure 1 is the system model of the present invention. figure 1 A two-layer heterogeneous network system composed of macro base stations and small cells is presented. In the system structure, there is a macro base station (MBS) and several small cell micro base stations (SBS), wherein the macro base station has a large number of antennas, and the micro base station has only one antenna. The macro base station serves the macro user (MU) and several micro base stations of the small cell network, and each small cell micro base station serves a mobile terminal (SU).
[0034] figure 2 For the concrete method flow process of the present invention, mainly comprise the following steps:
[0035] Step 1. Establish a two-layer heterogeneous network system with large-scale MIMO and dense small cells;
[0036] The total energy of the downlink in the network system is:
[0...
