Abstract

The invention discloses an uplink signal sending method and device. The uplink signal sending method includes generating to-be-sent uplink demodulation reference signals in a first time frequency unit, wherein the frequency domain of the first time frequency unit is a single sub carrier or a plurality of sub carriers; mapping the uplink demodulation reference signals to a first time frequency position of the first time frequency unit; sending the uplink demodulation reference signals in the first time frequency unit and uplink data corresponding to the uplink demodulation reference signals. According to the invention, through reasonable design of the uplink data sending method, a problem that the uplink demodulation reference signals cannot be sent by taking the sub carrier as the modulation unit in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an uplink signal sending method and device. Background technique [0002] With the development of wireless communication technology, in mobile network applications, the demand for traffic, the number of terminals and the types of terminals all show an explosive growth trend. The fifth generation mobile communication technology (5th Generation, referred to as: 5G) has become The trend of future network development. Machine Type Communication (MTC for short), as one of the important scenarios and technical means of the 5G system, has received more and more attention. [0003] MTC, also known as machine-to-machine (M2M) communication, is a main application form of the Internet of Things at the present stage. Currently, the MTC devices deployed in the market are mainly based on the Global System of Mobile communication (GSM) system, and several of them are di...
