Title:
DATA TRANSMISSION METHOD AND DEVICE AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/149865
Kind Code:
A1
Abstract:
A data transmission method and device and a communication system. The method comprises: carrying out phase rotation on a random access preamble sequence according to data to be transmitted so as to enable the data to be transmitted to be borne on the random access preamble sequence; and sending the random access preamble sequence, bearing the data to be transmitted, on a physical random access channel. Hence, random access and data transmission can be realized in one transmission step, the transmission efficiency is high, the overhead is small, and MTC equipment can efficiently transmit data.
