Abstract

The invention discloses a method and a device for reducing terminal energy consumption, and relates to the communication field. The power value used by each terminal during work is counted within the sampling period, the statistical power value samples are analyzed, and the minimum power value that meets the predetermined conditions is used as the transmitted power value, and the transmitted power value is fed back to the corresponding The terminal, so that the terminal uses the issued power value to work. The present invention is based on the characteristics that the terminal deployment position is fixed and the wireless environment of the terminal is relatively stable in the mMTC communication scene. Through the analysis of the statistical characteristics of the terminal transmission power, the most economical power transmission is adopted to ensure that the transmission can be successful once, reducing the transmission trial and error. The number of subsequent power adjustments reduces the energy consumption of the terminal and prolongs the battery life of the terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for reducing terminal energy consumption. Background technique [0002] The Massive Machine-Type Communication (mMTC) scenario is one of the three important scenarios in the future 5G communication network. The mMTC scenario is mainly for application scenarios such as environmental monitoring, smart agriculture, and forest fire prevention that target sensing and control, and is required to meet the million / square kilometer connection density index. The main characteristics of terminals in the mMTC scenario include ultra-high density (millions of connections per square kilometer), extremely low number of transmissions (several or a dozen bytes) and fixed, battery-driven (low cost, limited output power), ultra-high Long standby time (at least 10 years), the terminal deployment position is fixed, and the wireless environment where the terminal is located is rel...
