Abstract: A method for establishing a communication connection between a station (STA) and an access point (AP). The method includes: receiving, by the AP, request frames sent by N STAs to the AP, and after the AP receives the request frames sent by the N STAs, contending for a channel by the AP and sending one response frame to M STAs, where the response frame includes identifiers of the M STAs and M responses to the M STAs. Each of the identifiers of the M STAs corresponds to one of the M responses, wherein 2≤M≤N.

Abstract: The present disclosure provide a transmission method and a device, which relate to the technical field of communications and reduce overhead and improve work efficiency in an application of cooperative transmission in aspects of synchronization, sharing of information such as data and the like, obtaining of channel information and data transmission. Meanwhile application scenarios may also be extended. The method specifically includes: obtaining, by an access point AP, a parameter value, wherein the parameter value is a frequency difference between a crystal oscillator frequency of the AP and a reference crystal oscillator frequency of a reference AP or a delay difference of the AP with respect to the reference AP; compensating, by the AP, a phase difference or a time difference according to the parameter value when both of the AP and the reference AP send data. The present disclosure is applied to an application of a cooperative transmission.

Abstract: The present application provide a resource allocation method, an access point, and a station. The method includes: determining a resource allocation sequence of N stations in a wireless local area network and a position of a resource allocated to each station in the N stations; determining resource allocation information according to the resource allocation sequence of the N stations and the position of the resource allocated to each station in the N stations, where the resource allocation information is used to reflect a relative position of the resource allocated to each station in the N stations; and sending resource indication information, so that each station in the N stations obtains, according to the resource indication information, the position of the resource allocated to each station. The method utilizes redundancy between indication information of different stations, so signaling overheads of resource indication information can be reduced.

Abstract: A method includes determining at least one first station; and sending first indication information to the first station, where the first indication information is used for indicating at least one first backoff duration, so that the first station performs a data transmission operation by using the first backoff duration, and the first backoff duration used by the first station to perform a data transmission operation is less than a second backoff duration used by a second station to perform a data transmission operation, or the first backoff duration used by the first station to perform a data transmission operation is greater than the second backoff duration used by the second station to perform a data transmission operation. Shortening backoff durations of some stations can ensure that these stations send data first, and extending backoff durations of some stations can ensure that the other stations send data first.

Abstract: The present invention discloses a data transmission method and apparatus. The method includes: receiving a channel reservation request frame sent by a first station, where the channel reservation request frame is used to request to reserve a transmission resource for the first station for sending uplink data; sending a channel reservation response frame to the first station and M second stations according to the channel reservation request frame, where the channel reservation response frame is used to indicate that the first station and the M second stations are allowed to send uplink data. According to the data transmission method and apparatus of the embodiments of the present invention, time-frequency resources of a system can be reduced when MU-MIMO is implemented, a transmission delay can be shortened, and user experience can be improved.

Abstract: This application discloses an authentication and association method and system. An access point AP receives an authentication request sent by a station STA that needs to establish a connection to a service device; the AP establishes authentication with the STA; after the STA sends an association request to the service device, the AP receives an authentication result query request sent by the service device, and sends a result of the authentication result query request to the service device, so that the service device determines whether to establish an association with the STA; if the result shows that the STA is authenticated by the AP, the service device can establish an association with the STA; or if the result shows that the STA fails to be authenticated by the AP, the STA cannot establish an association with the service device.
