Problems solved by technology

[0004] In addition, some MTC devices need to be installed in the basement of residential buildings or in locations protected by insulating foils, metal windows, or thick walls of traditional buildings. Compared with conventional equipment terminals (such as mobile phones, tablet computers, etc.) will suffer significantly more severe penetration losses

Abstract

The invention provides an uplink reference signal transmission method executed by user equipment UE. The method comprises the following steps: determining one or a plurality of parameters, wherein the one or a plurality of parameters are used for generating a Demodulation Reference Signal DMRS of a Narrowband Internet of Things Physical Uplink Control Channel NB-PUCCH, wherein for single-tone uplink transmission, a parameter used for generating the DMRS comprises an orthogonal cover code OCC sequence and a basic sequence; for multi-tone uplink transmission, a parameter used for generating the DMRS comprises cyclic shift, the OCC sequence and the basic sequence; based on the determined parameters, generating the DMRS of the NB-PUCCH; and transmitting the generated DMRS of the NB-PUCCH to a base station. Correspondingly, the invention further provides an uplink reference signal receiving method executed by the base station, and the UE and the base station which respectively execute the above method.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to an uplink reference signal transmission method and a receiving method, as well as user equipment and a base station respectively executing the above methods. Background technique [0002] With the rapid growth of mobile communication and the great advancement of technology, the world will move towards a fully interconnected network society, that is, anyone or anything can obtain information and share data at any time and anywhere. It is estimated that by 2020, the number of connected devices will reach 50 billion, of which only about 10 billion may be mobile phones and tablet computers, and the rest are not machines that talk to people, but machines that talk to each other. Therefore, how to design a system to better support the Internet of Everything is a topic that requires in-depth research. [0003] In the Long Te...
