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: A resource allocation method includes sending, by a first device, resource allocation information to a second device. The resource allocation information indicates a first virtual resource unit (VRU). The first VRU includes a plurality of contiguous subcarriers in a frequency domain. The resource allocation method also includes mapping, by the first device, the first VRU to a first physical resource unit (PRU) based on a mapping relationship. The resource allocation method further includes transmitting data on the first PRU. A plurality of subcarriers included in the first PRU are noncontiguous in the frequency domain.

Abstract: Embodiments of this application relates to a multi-link communication setup method and a related apparatus. The method includes: a non-AP MLD sends an association request frame on a first link, to request multi-link setup. An AP MLD returns an association response frame on the first link, to notify whether multi-link setup succeeds. The AP MLD sets a second status code field of a multi-link element of the association response frame to a newly defined value, to indicate that a cause why a link is not accepted is that the first link is not accepted. This application is applied to a WLAN system that supports a next generation Wi-Fi protocol of 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and other 802.11 series protocols; and for another example, a next generation protocol of 802.11be: Wi-Fi 8.
