    摘要: Embodiments of the present invention 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).

    摘要: Embodiments of the present invention provide a method, an access point, and a station for transmitting channel state information. The method includes: receiving, by a station, a feedback indication message, a high-efficiency long training sequence, and a resource scheduling message that are sent by an access point; and when it is determined that the station belongs to target stations, feeding back an acknowledgement message to the access point by using a communication resource indicated by the resource scheduling message. The feedback indication message is used to indicate at least two target STAs that need to feed back channel state information to the AP, and the high-efficiency long training sequence is used to determine channel state information of the STA. In the embodiments of the present invention, an acknowledgement message is fed back to an access point. In this way, resource waste caused when some stations cannot immediately perform feedback can be avoided, and channel state information transmission efficiency can be improved.

    摘要: Embodiments of the present invention provide a method for sending an uplink multi-user transmission trigger frame, an access point, and a station. The access point sends, to a station, a beacon frame that carries a trigger frame information element, where the trigger frame information element includes sending information of a trigger frame. The station obtains a target transmission time sequence of the trigger frame according to the sending information. The access point contends for a channel when a target transmission time of the trigger frame arrives, and the access point sends the trigger frame to the station after the contention succeeds. In this case, the station switches to an active state, and receives the trigger frame by listening to the channel, and the station performs uplink transmission according to indication of the trigger frame after receiving the trigger frame. In this way, when signaling overheads are not increased and reliability is ensured, a station can learn of a sending time of a trigger frame, and the station remains in a receiving state in an appropriate period of time.

    摘要: Embodiments of the present invention propose a data transmission method, including: determining, according to a maximum power value detected by performing a CCA on a primary channel in one or more processing time periods, a power value interval to which the maximum power value detected by performing the CCA belongs, where the determined power value interval is one of one or more power value intervals that do not overlap each other; obtaining a transmit power spectral density according to the determined power value interval, where there is a one-to-one correspondence between the one or more power value intervals and one or more transmit power spectral densities; and when a TXOP is obtained, performing data transmission on a transmission channel by using a power spectral density that is not greater than the transmit power spectral density. A corresponding power value interval is determined by considering a maximum power value detected by performing a CCA on a primary channel, so as to obtain a transmission channel and a transmit power spectral density that are most suitable for a current channel status, so that a probability of accessing a channel by a station is increased, and the station may use a power spectral density as large as possible to perform data transmission, so as to maximize transmission efficiency of a system.

    摘要: Embodiments of the present invention provide an association establishment method and apparatus. The method includes: broadcasting, by an AP, a trigger frame, where the trigger frame is used to indicate one or more available subchannel and trigger multiple first STAs to perform uplink data transmission at the same time; receiving, by the AP, an association request message sent on a corresponding available subchannel by each first STA; broadcasting, by the AP, a multi-block acknowledgement M-BA frame, where the M-BA frame includes one or more piece of association acknowledgement information, where if the trigger frame includes a temporary identifier that is allocated by the AP to an available subchannel, the association acknowledgement information includes a MAC address of one or more second STA; otherwise, the association acknowledgement information includes a MAC address of one or more second STA and a first AID that is allocated by the AP to the second STA; and sending, by the AP, an association response message to the second STA according to the first AID, where the association response message is used to indicate that an association is successfully established. In this way, the AP is associated with the second STA, and communication reliability is ensured.
