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: Embodiments of the present invention provide an association establishment method and apparatus. The method includes: broadcasting, by an access point AP, a trigger frame, wherein the trigger frame is used to trigger one or more unassociated stations STAs to perform uplink data transmission and indicate one or more available subchannels for random accessing of the unassociated STAs; receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs; broadcasting, by the AP, a multi-block acknowledgement M-BA frame, wherein the M-BA frame includes one or more pieces of association acknowledgement information and the association acknowledgement information is acknowledgement information of the association request message. In this way, the AP is associated with the unassociated stations STA, and communication reliability is ensured.

Abstract: This application provides a wake-up method and device. The method includes: receiving, by a wake-up radio, a first wake-up frame, where the first wake-up frame includes a duration field, and the duration field is used to carry duration information; and waking up, by the wake-up radio, a primary radio based on the duration information. Because a wake-up frame transmitted by an access point includes duration information, a wake-up radio of a station wakes up a primary radio based on the duration information, so that the station can save energy better.

Abstract: A receiving state indication method for an aggregate-media access control (MAC) protocol data unit (A-MPDU) and a receiving device, to indicate a receiving state of an A-MPDU including a MAC service data unit (MSDU) fragment. The method includes receiving, by a receive end, an A-MPDU sent by a transmit end; and when determining that at least one MAC protocol data unit (MPDU) in the A-MPDU is obtained by encapsulating a fragment of an MSDU, sending, by the receive end to the transmit end, an acknowledgement frame used to indicate a receiving state of the A-MPDU, where the acknowledgement frame includes a fragment indication field and a receiving state field.

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.
