Method, device and system of machine terminal communication

Abstract

The invention discloses a method, a device and a system of machine terminal communication. The method includes: analyzing configuration information of physical downlink control channels from received main system information (MIB); and according to the configuration information, receiving downlink control information carried by a physical downlink control channel from the corresponding physical downlink control channel. According to the method, the device and the system of the machine terminal communication, a base station sends the MIB containing the configuration information of the physical downlink control channel to a terminal, and the terminal can receive the downlink control information on the corresponding physical downlink control channel according to the configuration information. Thus, the method, the device and the system of the machine terminal communication achieve that a machine-type communication (MTC) terminal only receives the downlink control information on the bandwidth of a working carrier wave, thus achieve that when the MTC terminal and an ordinary commercial terminal shares the same carrier wave, radio frequency receiving and transmitting capacity of the MTC terminal does not need to be promoted, and reduce cost of the MTC terminal.

Description

technical field [0001] The present invention relates to a wireless technology, in particular to a machine terminal communication method, device and system. Background technique [0002] Such as figure 1 As shown, machine-type communication (machine-type communication, MTC for short) refers to a communication mode between machines (devices and devices) that does not require human participation. The current core network specification 3GPP 22.368 defines 16 important features in MTC communications, including low mobility, time control, delay tolerance, and online small data transmission. For different applications, including meter reading applications, remote control, etc., it may have one feature or a combination of several features. [0003] Since spectrum resources are very precious, at the beginning of MTC business development, it is an effective solution to improve the utilization of spectrum resources to consider sharing the carrier with everyone for communication.

AI Technical Summary

Problems solved by technology

For MTC terminals, on the one hand, the amount of downlink data is very small. If it works on a 20M carrier, it does not need a transmission rate of 20M bandwidth.

On the other hand, the RF transceiver capability is one of the factors that affect the cost of the terminal. If the MTC terminal and the common commercial terminal share the carrier work according to the existing technology, it must be ensured that the MTC terminal and the common commercial terminal must have the same RF transceiver capability. It not only increases the cost of the MTC terminal, but also such a radio frequency capability is also a waste for the MTC terminal
