Problems solved by technology

However, in this scheme, the cluster size is fixed and the cooperative transmission power consumption and backhaul power consumption are not considered.
In short, the existing static cluster or fixed cluster size to improve the energy efficiency of the system cannot satisfy the dynamic changes of users or minimize energy consumption.

Embodiment Construction

[0039] The present invention is described in further detail below in conjunction with accompanying drawing:

[0040] refer to figure 1 According to the present invention, the energy-efficiency cooperative base station sleep mechanism in the dense network improves the method for system energy efficiency comprising the following steps:

[0041] 1) Construct a system model. During non-communication peak hours, densely deploy network downlink CoMP transmission scenarios. Among them, there are A cells in the system, and there are L cells in cell k. k randomly distributed users, k∈Θ, Θ={1,2,...,A}, users and base stations are configured with a single antenna, there is a sleeping base station in the system, and the SINR of user l in cell k is calculated lk and data rate r lk ;

[0042] 2) According to the SINR of each user, users are divided into CoMP users and central users, and then dynamically select clusters according to the results of user division, and then in non-peak periods...

Abstract

The invention discloses a method for improving system energy efficiency of an energy efficiency cooperation base station dormancy mechanism in a dense network. The method comprises the following steps: 1, constructing a system model, in a non-communication peak period, densely disposing network downlink CoMP transmission scenes to obtain SINR<1k> and a data rate r<1k> of a user 1 in a cell k; 2, dividing users into CoMP users and center users, then carrying out dynamic clustering, in a communication off-peak period, selecting priority dormancy base stations, and distributing the users in a dormancy cell to base stations satisfying information rate of the users in the dormancy cell; 3, establishing a power consumption model, obtaining total power Ptotal of a CoMP system, and obtaining additional power consumption PCoMP generated by cooperation base stations in a work process; 4, establishing an optimization problem model with minimum system power consumption; and 5, solving the optimization problem model with the minimum system power consumption, and then according to a solution result, carrying out information communication between each station in a system and the users. According to the invention, the requirements of the users for dynamic change can be met, and the power consumption of the system is quite small.
