Problems solved by technology

Since the MTC UE only needs to obtain the SFN in the MIB to ensure normal communication with the base station, but the MTC UE needs to receive all the MIB to obtain a complete SFN, therefore, the MTC UE in a low-coverage environment may appear due to transmission The performance is low, resulting in the failure to receive the SFN from the base station normally
[0004] It can be seen that in the prior art, the MTC UE may not be able to complete the communication with the base station due to the low transmission performance

Abstract

The invention discloses a system frame number (SFN) information transmission method. The method comprises steps: when a base station dispatches the SFN to the terminal, the base station bears the SFN information on an enhanced physical broadcast channel (Enhanced PBCH), wherein each unit frame comprises a plurality of Enhanced PBCHs; and the base station sends the SFN information to the terminal via the Enhanced PBCHs. The invention also discloses an SFN information transmission system and a device. Thus, transmission performance of the LTE (Long Term Evolution) system to the base station and to the terminal can be improved, and normal communication demands of the terminal can be ensured.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for transmitting System Frame Number (SFN, System Frame Number) information. Background technique [0002] MTC User Equipment (MTC UE, MTC User Equipment) is the main application form of the Internet of Things at the present stage. Due to its low power consumption and low cost, MTC UE has been widely used. [0003] Currently, in a Long Term Evolution (LTE, Long Term Evolution) system, an MTC UE completes normal communication with a base station by acquiring information from a Master Information Block (MIB, Master Information Block). Since the MTC UE only needs to obtain the SFN in the MIB to ensure normal communication with the base station, but the MTC UE needs to receive all the MIBs to obtain a complete SFN, therefore, the MTC UE in a low-coverage environment may appear due to transmission The performance is low, so that the SFN sent b...
