Abstract

The present invention provides a transmission method for multiple access, including: the transmitter performs channel coding on the bit sequence to determine the coding sequence; performs symbol modulation on the coding sequence; performs grid mapping on the modulated symbol sequence to determine Mapped sequence, and send the mapped sequence. The present invention also provides a multiple access method, including: the receiver receives mixed signals from multiple transmitters, and the mixed signal is a signal obtained after each of the multiple transmitters processes data through grid mapping or The signal obtained after the data is interleaved and grid-mapped; according to the grid-mapping pattern information corresponding to each transmitter or the corresponding interleaving pattern information or scrambling code information and the grid-mapping pattern information, the mixed signal is decoded to obtain signals from each transmitter. transmitter data. The present invention decodes data from different transmitters by using different interleaving patterns or scrambling code information and / or grid mapping patterns to realize the distinction of multiple transmitters.

Description

technical field [0001] The present invention relates to the field of mobile communication, specifically, the present invention relates to a multiple access method, a transmission method for multiple access, a transmitter and a receiver for multiple access. Background technique [0002] With the rapid development of the information industry, especially the growing demand from the mobile Internet and IoT (Internet of Things, Internet of Things), it brings unprecedented challenges to future mobile communication technologies. For example, according to the report ITU-R M.[IMT.BEYOND 2020.TRAFFIC] of the International Telecommunication Union ITU, it can be predicted that by 2020, the growth of mobile traffic will increase by nearly 1,000 times compared to 2010, that is, in the 4G era. UE (User Equipment , user equipment) connections will also exceed 17 billion. As massive IoT devices gradually penetrate into mobile communication networks, the number of connected devices will becom...
