摘要：
The sixth generation of mobile communications system (6G) will reveal significant improvements in the key performance indicators and support diverse communication scenarios, which put forward higher requirements on the coded modulation technologies. First, the advantages of the polar-coded modulation (PCM) in 6G are investigated. Then, the principles of multilevel PCM (MLC-PCM) and bit-interleaved PCM (BIPCM) are discussed for high spectral efficiency and low latency scenarios, respectively. Since the existing construction methods encounter the problems of high complexity and poor flexibility, a universal construction framework of PCM is proposed, and this framework is discussed in detail under MLC-PCM and BIPCM schemes. This construction method utilizes sum rate approximation to assign code rates to polar component codes, which performs independently of the actual channel conditions and can significantly reduce the construction complexity of PCM. Simulation results are also provided to verify its flexibility and universality. In addition, the PCM schemes constructed by the proposed methods show better performance than the low-density parity-check-coded mpdualtion schemes in the fifth generation of mobile communications system. © 2022, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
