Publication number: 20240129099Abstract: Embodiments of this disclosure provide a communication method and device, a storage medium, and a program product. According to the communication method of this disclosure, a physical layer protocol data unit (PPDU) is transmitted or received based on a tone plan of a first bandwidth. The tone plan includes a physical resource unit (PRU), and the PRU includes discrete subcarriers. According to embodiments of this disclosure, an original nominal RU is processed to obtain a PRU including discrete subcarriers. Discretized subcarriers of the PRU may be evenly distributed on a larger bandwidth without changing subcarrier division of the original nominal RU. When it is ensured that a large PAPR is not generated in data transmission due to discrete subcarriers, a transmit end can perform communication at a high transmit power.Type: ApplicationFiled: December 20, 2023Publication date: April 18, 2024Inventors: Chenchen LIU, Bo GONG, Jian YU, Yuxin LU, Ming GAN
