Abstract: The present disclosure relates to communication methods and apparatuses, and relates to the field of communication technologies. In one example method, a first communication apparatus generates a physical layer protocol data unit (PPDU), and sends the PPDU to a second communication apparatus. The PPDU includes a first field with 26 bits, and the first field includes a one-bit unsolicited modulation and coding scheme (MCS) feedback (MFB) subfield and a one-bit first indication information. When a value of the unsolicited MFB subfield is a first value, the first indication information indicates an MCS request (MRQ). When a value of the unsolicited MFB subfield is a second value, the first indication information indicates an uplink extremely high throughput trigger-based PPDU MFB (UL EHT TB PPDU MFB).

Abstract: 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.

Abstract: This application relates to a communication method and related apparatuses. The method includes: A first communication apparatus generates and sends a first frequency domain signal, where the first frequency domain signal includes a sub signal obtained by mapping N pieces of first frequency domain data to a first group of subcarriers and a subsignal obtained by mapping N pieces of second frequency domain data to a second group of subcarriers, and a spacing between the first group of subcarriers and the second group of subcarriers is odd-numbered subcarriers. The N pieces of first frequency domain data are obtained by multiplying data at even positions or data at odd positions in N pieces of original frequency domain data by i or —i, and the N pieces of second frequency domain data are obtained by performing reverse arrangement and/or negation on the N pieces of first frequency domain data.
