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.
Claims34
An access point (AP), comprising:
- a processor;
- a non-transitory memory;
- and
- a radio interface;
- wherein the memory is configured to store instructions;
- wherein the radio interface is configured to connect the AP and N stations (STAs), wherein N is a natural number greater than or equal to 2;
- wherein the processor is coupled to the memory, and is configured to read and execute the instructions in the memory to:
- receive, using the radio interface, N request frames sent by the N STAs;
- and
- contend, in response to receiving an Nth request frame, for a channel and send, using the radio interface, a single response frame to M STAs of the N STAs on the channel after successful contention, wherein N is selected by the AP according to at least one of expiration of a timer started after receiving a first request frame of the N request frames or a maximum quantity of users that can be supported by a downlink frame, wherein the response frame comprises identifiers of each of the M STAs and further comprises M responses to the M STAs, wherein each of the identifiers of the M STAs corresponds to one of the M responses and is generated according to a media access control (MAC) address of a respective STA of the M STAs, and the identifiers and the M responses instruct the M STAs to receive respective responses from the response frame sent by the AP, wherein M is a natural number, and 2≤M≤N;
- wherein the N request frames are one of authentication frames or association request frames.

- and
- obtain an identifier of the STA, and match the obtained identifier of the STA against the identifiers of the M STAs in the response frame, so as to obtain a response with respect to the STA from the M responses.
