Abstract: An association establishment method and apparatus for carrying out the method are described. The association establishment 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. The method further comprises receiving, by the AP, one or more association request messages sent on available subchannels acquired by the unassociated STAs. Thereafter, the AP broadcasts 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.

Abstract: Example methods for indicating downlink service data and devices are described. One example method includes controlling, by a first station (STA) associated with a radio access point (AP), a wake-up receiver of the first STA to wake up within a preset first listen interval. The first STA receives a wake-up beacon frame sent by the AP, and controls main radio (MR) of the first STA not to wake up within a second listen interval to receive a beacon frame sent by the AP. According to the method provided in this application, the MR of the first STA does not need to wake up within the second listen interval to receive the beacon frame broadcast by the AP.

Abstract: In a method of sending a frame using a cyclic shift diversity (CSD) sequence, a wireless device generates a frame comprising a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal (L-SIG) field, a repeated legacy signal (RL-SIG) field, an extremely high throughput signal A (EHT-SIG A) field, and an extremely high throughput signal B (EHT-SIG B) field. The wire device sends the frame through a set of transmit antennas by performing cyclic shift over the fields according to a CSD sequence. The number of transmit antennas is greater than 8. The number of cyclic shift diversities in the CSD sequence is equal to a number of the transmit antennas, and each cyclic shift diversity has a value that is a multiple of 12.5.

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: 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.
