Abstract

The present invention relates to the technical field of communications, and relates to a symbol mapping method and user equipment, wherein the symbol mapping method comprises: acquiring mapping mode information; and performing symbol mapping on the to-be-sent symbol sequence based on the obtained mapping mode information. According to the invention, mapping from symbols to resource elements is realized, and the method has the characteristics of simple processing, low complexity and low performance loss.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, the present invention relates to a symbol mapping method and user equipment. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and the Internet of Things (IoT, Internet of Things), unprecedented challenges have been brought to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND2020.TRAFFIC] of the International Telecommunication Union (ITU), it can be predicted that by 2020 (compared to the 4G era in 2010), the mobile service volume will increase nearly 1,000 times. The number of user terminal connections will also exceed 17 billion. As a large number of IoT devices gradually penetrate into the mobile communication network, the number of connected devices will become even more astonishing. [0003] To cope with this unprece...
