Abstract

The invention provides a transmission method for an enhanced random access sequence and an MTC terminal. The method comprises that a node 1 generates the enhanced random access sequence according to a random access sequence and enhanced configuration information; and the node 1 sends the enhanced random access sequence in an enhanced random access channel. According to the invention, the random access channels of an LTE / LTE-A system are enhanced in design, the access quality of the MTC terminal can be improved, and it is ensured that the MTC terminal can normally access the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to an enhanced random access sequence transmission method and a machine type communication terminal. Background technique [0002] Machine Type Communication (MTC for short) User Equipment (MTC User Equipment, MTC UE for short) or Machine Type Communication Terminal (MTC Terminal for short) or Machine to Machine (M2M for short) user Communication equipment is the main application form of the Internet of Things at this stage. Low power consumption and low cost are important guarantees for its large-scale application. M2M devices currently deployed in the market are mainly based on the Global System of Mobile communication (GSM for short) system. In recent years, due to the high spectrum efficiency of Long Term Evolution / Long Term Evolution-Advanced (LTE / LTE-A for short), more and more mobile operators have chosen LTE / LTE-A as the future Evolution direction of wireless communicati...
