Abstract: Embodiments provide resource scheduling methods and apparatus that reduce transmission resource overhead in resource scheduling. The method can be applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units potentially allocated from a to-be-assigned frequency domain resource. The method includes: generating, by a sending end, resource scheduling information, where the resource scheduling information includes a bit sequence to indicate an actual allocation of a resource unit(s) from the to-be-assigned frequency domain resource, and at least some bits in the bit sequence to indicate whether one or more of the resource unit locations potentially allocated for the to-be-assigned frequency domain resource are the actually allocated resource units.

Abstract: A method and system for providing utilization information for a basic service set (BSS) in a wireless local area network system, performed by an access point, including generating and transmitting a BSS load element including a capable STA count field, a plurality of frequency and/or spatial stream underutilization fields, and a plurality of delta observable secondary channel utilization fields. The capable STA count field indicates a total number of STAs currently associated with the BSS. Each of the frequency and/or spatial stream underutilization fields indicates underutilized frequency and/or spatial stream domain resources on Orthogonal Frequency Division Multiple Access resource units for each channel, and each of the frequency and/or spatial stream underutilization fields is calculated based on RU size. Each of the delta observable secondary channel utilization fields indicates a utilization for a subband within a secondary channel calculated based on observable utilization on the corresponding secondary channel.

Abstract: An AID allocation method for a multi-link device, includes: An access point multi-link device generates and sends a first frame. Correspondingly, a station device receives and parses the first frame to obtain an AID that is allocated to the station device and carried in the first frame. The AID is neither a BSSID that can be supported by a first-type access point in the access point multi-link device nor an identifier of an access point in the access point multi-link device. The first-type access point is an access point for establishing a link between the station device and the access point multi-link device.

Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. An AP generates a trigger frame, where the trigger frame includes a first user information field, a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field before the first user information field is located on a primary 160 MHz channel, and a part or all of a frequency domain resource indicated by a resource unit allocation subfield in a fourth user information field after the first user information field is located on a secondary 160 MHz channel. Then, the AP sends the trigger frame.

Abstract: APPDU-based communication method and apparatus are disclosed, are used in a wireless local area network system that supports 802.11 series protocols such as a next-generation Wi-Fi protocol of IEEE 802.11ax, for example, 802.11be, Wi-Fi 7, or EHT, and a next-generation protocol of 802.11be, for example, Wi-Fi 8. A transmit end generates a PPDU, and sends the PPDU on a first high frequency channel. Correspondingly, a receive end receives the PPDU on the first high frequency channel, and processes the PPDU. The first high frequency channel may include a first pilot subcarrier and a first data subcarrier, a quantity of first pilot subcarriers is greater than a quantity of second pilot subcarriers, and a quantity of first data subcarriers is equal to a quantity of second data subcarriers. This can effectively improve demodulation accuracy of the receive end.
