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.

Abstract: This application provides a method for transmitting a PPDU and a communication apparatus. An AP sends a trigger frame to trigger at least one STA to transmit an uplink PPDU. After receiving the trigger frame, the at least one STA transmits respective uplink PPDUs. The uplink PPDU includes a data field and LTFs. The data field is carried on a distributed RU. The LTFs are carried on all subcarriers in a first transmission bandwidth. The first transmission bandwidth is a bandwidth occupied by a distributed RU that is allocated by the AP to the at least one STA for transmitting the uplink PPDU. Alternatively, the LTFs are carried on all subcarriers of a plurality of continuous RUs corresponding to the distributed RU.

Abstract: The technology of this application relates to a communication method and apparatus, to not only improve transmission efficiency in a distributed resource unit (DRU) transmission mode, but also improve system performance due to a relatively low peak-to-average ratio (PAPR) of a long training field (LTF) included in a trigger-based physical layer protocol data unit (TB PPDU) transmitted based on a DRU. In an example embodiment, a station (STA) receives a trigger frame, where the trigger frame includes DRU indication information, and the DRU indication information indicates a DRU used by the STA to send a TB PPDU. The STA sends the TB PPDU on the DRU, where the TB PPDU includes a long training field (LTF).

Abstract: A cyclic shift diversity-based communication method and apparatus. A maximum number of antennas supported in this method is greater than 8. A cyclic shift is performed on a first preamble part of each antenna by using a cyclic shift diversity value, so that an automatic gain control error is reduced in response to the use of more antennas (for example, 16 antennas).
