Abstract: The technology of this disclosure relates to a signal modulating method, a signal demodulating method, a device, a storage medium, and a program product. In the signal modulating method according to a first aspect of this disclosure, a sending device modulates a bit sequence onto a plurality of subcarriers through binary phase shift keying (BPSK) constellation point mapping, dual carrier modulation (DCM), and a duplication (DUP) operation, where the plurality of subcarriers include a first group of subcarriers and a second group of subcarriers. Then, the sending device changes a phase of first data carried in the first group of subcarriers by 90 degrees or minus 90 degrees, and further generates a modulation signal based on the first data that is carried in the first group of subcarriers and whose phase has been changed and second data carried in the second group of subcarriers.

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 provides a communication method and a multi-link device. The method includes: When only one of a plurality of links is successfully established, a first MLD performs air interface transmission with a second MLD according to a single-link communication rule. The plurality of links may be a plurality of links that the first MLD requests to establish, or the plurality of links may be a plurality of links that have been successfully established between the first MLD and the second MLD. According to the solution in this application, when only one of the plurality of links is successfully established, the first MLD does not perform air interface transmission with the second MLD according to a multi-link communication rule. Specifically, an address 2 field carried in a frame over the air that is sent by the first MLD is a MAC address of the first MLD.

Abstract: The present disclosure relates to communication methods and apparatuses. In one example method, a non-access point multi-link device (non-AP MLD) receives a first frame from a first access point (AP) when performing a listening operation on a first link. The non-AP MLD switches some or all of spatial streams/antennas on each link of the non-AP MLD to the first link to perform a frame exchange with the first AP. When determining that any preset condition in a preset condition set is met, the non-AP MLD switches some spatial streams/antennas on the first link back to each link or another link to perform the listening operation.
