Problems solved by technology

[0004] However, in the Internet of Things, the frequency deviation of the device usually causes timing drift, and the longer the accumulation time of the signal, the more serious the time drift is, which makes the detection performance of the terminal to the broadcast information in the system signal greatly degraded, Difficult to guarantee deep coverage of the signal

Abstract

The present application provides a signal transmission method, a base station, a terminal, and a communication system, wherein the signal transmission method includes: the base station determines the transmission period of the system signal transmitted by the base station, and the system signal is broadcast by the base station to multiple terminals signal; the base station sends the system signal according to the transmission cycle, and sends a deep coverage signal after sending the system signal every at least one transmission cycle, and the deep coverage signal carries the same signal as the system signal broadcast information. The application can improve the detection performance of the terminal to broadcast information, and increase the depth of signal coverage.

Description

technical field [0001] The present application relates to communication technology, in particular to a signal transmission method, base station, terminal and communication system. Background technique [0002] The Internet of Things (IoT) can connect sensors, controllers, machines, people and things in a new way by using communication technologies such as local networks or the Internet to form a relationship between people and things, things and things. Connected to realize informatization, remote management control and intelligent network. [0003] In the Internet of Things, different devices may have different communication environments. Due to business requirements, some devices need to be configured in some scenes with shelter and shielding, such as deep in buildings and underground. However, occlusion and shielding make these scenes become signal coverage blind spots. In this signal coverage hole, the transmission strength of the signal is usually weak, which makes t...
