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 that the base station determinesa transmission period at which the base station transmits a system signal, wherein the system signal is broadcasted by the base station to a plurality of terminals; and the base station transmits thesystem signal according to the transmission period, and transmits a deep coverage signal after transmitting the system signal every other at least one of the transmission periods, wherein the deep coverage signal carries the same broadcast information as the system signal. The method can improve the detection performance of the terminal on the broadcast information and improve the signal coveragedepth.

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 deployed in some sheltered and shielded scenes 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 the cove...
