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: This application provides communication methods, apparatuses, and computer-readable storage media. In an example, a value of a specific element of a first access point (AP) (or a second AP) is reused in a management frame, to indicate specific elements of a plurality of APs in a multiple basic service set identifier (BSSID) set to which the first AP (or the second AP) belongs. The management frame does not need to carry a plurality of same specific elements in the multiple BSSID set. The described techniques can be applied to, for example, a wireless local area network system supporting IEEE 802.11ax next-generation Wi-Fi protocols, for example, 802.11 series protocols such as the 802.11be or the EHT.

Abstract: A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.
