Abstract: This application relates to the wireless communications field and provides a frame transmission method, device, and system. The method includes: sending, by a second device, n wake-up frames to a first device, where the n wake-up frames each carry segmented content of wake-up signaling, so that a wake-up receiver of the first device wakes up a main transceiver of the first device based on the n wake-up frames, and after being woken up, the main transceiver sends, to the second device, a response frame used to indicate whether the n wake-up frames are correctly received. In this application, content of the wake-up signaling is segmented. In this case, lengths of the n wake-up frames are all relatively short, so that the wake-up receiver is easier to correctly receive each wake-up frame.

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: In a data transmission method, a station in a wireless network receives a trigger frame sent by an access point of the wireless network. The trigger frame includes an identifier of a target frequency domain resource unit RU allocated to the station. The station sends an uplink orthogonal frequency division multiple access physical layer protocol data unit OFDMA PPDU, where a data part of the OFDMA PPDU is sent in the target RU, and a common physical layer preamble of the OFDMA PPDU is sent in one or more fundamental channels in which the target RU is located. The station then receives from the access point an acknowledgement frame, which is sent in a response RU that is located in the one or more channels of the target RU.

Abstract: Embodiments provide a resource scheduling method, which can support reduction of transmission resource overheads in resource scheduling. The method is applied to a wireless local area network, where a next generation protocol followed by the wireless local area network predefines locations of resource units possibly 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 are to indicate whether one or more of said resource unit locations possibly allocated for the to-be-assigned frequency domain resource is\are the actually allocated resource unit(s).

Abstract: A first station generates indication information of any one of an operating channel, an operating band, or an operating channel and an operating band of a wake-up receiver in a second station. The first station sends the indication information, so that the wake-up receiver in the second station works on the indicated operating channel or the indicated operating band. The first station controls the operating channel or the operating band of the wake-up receiver in the second station by generating the indication information.

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.
