Non-orthogonal multiple access is faced with many problems not found in conventional orthogonal multiple access, such as more severe interference between multiple users. How to solve these problems, design efficient and reliable non-orthogonal multiple access scheme is a research direction.

Summary of the invention

The inventor found that in order to improve the reliability of non-orthogonal multiple access, the UE (User Equipment) needs to adopt a low code rate modulation and coding method to improve the anti-interference ability of the transmitted data, resulting in a decrease in transmission efficiency. .

The physical channel of the time domain multicarrier symbol stream. Each transmitter 1018 converts the baseband multi-carrier symbol stream provided by the transmit processor 1016 into a radio frequency stream, which is then provided to a different antenna 1020.

Each transmitter 1054 first converts the baseband symbol stream provided by the transmit processor 1068 into a stream of radio frequency symbols and provides it to the antenna 1052.

In UL (Uplink), the function at gNB 1010 is similar to the receiving function at UE 1050 described in the DL. Each receiver 1018 receives a radio frequency signal through its respective antenna 1020, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a receive processor 1070.
