Millimeter wave network performance analysis method based on three-level transmission power mechanism

Abstract

The invention discloses a millimeter wave network performance analysis method based on a three-level transmission power mechanism, and belongs to the field of wireless communication. The three-level transmission power mechanism implements the following strategy: transmission power is divided into single power, half power and zero power; each base station sets three levels of thresholds for the number of users accessed; when the number of users accessing each base station is smaller than the high threshold and greater than the low threshold, the base station implements half power; and when the number of users accessing each base station is reduced to below the low threshold, the base station transfers the existing users to an appropriate neighboring base station, and implements zero power. When the number of users accessing a base station is greater than a super threshold, part of users are transferred to an appropriate base station selected or to a nearest dormant base station awakened to ensure smooth communication. The network performance is analyzed by reference to coverage probability, transmission capacity and regional spectrum efficiency. The method of the invention, which is built on the basis of power control performed by base stations, can better reflect the actual network performance and further achieve the goal of green communication.

Description

technical field [0001] The invention belongs to the field of wireless communication, and more specifically relates to a millimeter wave network performance analysis method based on a three-level transmission power mechanism. Background technique [0002] With the increase in the number of network terminals and the increasing demand of users for high-definition video and real-time video and voice communication, the amount of network communication data is increasing geometrically. The traditional low data rate and low throughput network environment can no longer Meet the user's requirements. It is foreseeable that if a high-throughput, high-data-rate network is not sought for innovation, there will be a serious mismatch between the communication needs of users and the communication capabilities that existing networks can provide in the near future. In 5G wireless communication, high throughput, high data volume, high data rate, and good quality of service are its basic charac...
