Problems solved by technology

[0003] At present, there are few studies on the application of cross-layer design ideas to the establishment of EERA models of heterogeneous networks. However, due to the unique advantages of cross-layer design, EERA based on cross-layer design in heterogeneous networks is a trend to be studied.

Embodiment Construction

[0060] The present invention will be further described below in conjunction with drawings and embodiments.

[0061] The non-cooperative game-based resource allocation and interference suppression method in the LTE system provided by the present invention comprises the following steps:

[0062] (1) A heterogeneous network with 1 Macrocell and N Small cells (SCs) is established, and the number of users in each SC is M and they share K subcarriers. Macrocell can estimate the channel gain from SC n to the scheduled macro cell user (MU) (k=1,...K; n=1,...N; m=1,...M), however Macrocell cannot estimate the channel gain from SC n to SCU m It can only collect the channel gain from SC n to SCU m Fixed probability density distribution f(h); for any SC n, the channel gain from SC n to SCU m can be estimated Instead of estimating the channel gain from SC n to the scheduled macro cell user (MU) It can only collect the channel gain from SC n to the scheduled macro cell user (MU) ...

Abstract

The cross-layer resource allocation method based on the Stackelberg game in the heterogeneous network first establishes the heterogeneous network, and then establishes the MAC layer transmission control model and the physical layer model; according to the MAC layer and the physical layer model, establishes the JPMO optimization model; uses the Stackelberg game to The JPMO optimization model is divided into two sub-models; through the backtracking method, the energy-saving resource allocation model of the physical layer is first established on the SC end using the Lagrangian dual decomposition method to solve it, and then the optimal access control model of the MAC layer is established on the Macro end using A gradient-based iterative algorithm is used to solve the problem. Through cross-layer design and multi-user multi-channel diversity gain, the present invention reduces cross-layer interference of heterogeneous networks while saving energy, effectively improves system efficiency, and can realize joint interference management and resource allocation in heterogeneous networks. The simulation results show that Compared with the method without cross-layer design, this method effectively improves the utility of the system.

Description

technical field [0001] The invention belongs to the field of wireless communication, relates to a system-level network simulation of a wireless communication system, and in particular relates to a stackelberg game-based cross-layer resource allocation method in a heterogeneous network. Background technique [0002] The current development of battery technology cannot meet people's growing multimedia application needs. Energy efficiency is also an important link in the design of wireless communication systems. Energy-saving communication has become a current hot topic. In a heterogeneous network, Macrocell (Macro) and Small cell share the entire spectrum, which brings serious cross-layer interference and same-layer interference, which greatly reduces network efficiency. [0003] At present, there are few studies on the application of cross-layer design ideas to the establishment of EERA models of heterogeneous networks. However, due to the unique advantages of cross-layer des...
