Method for transmitting data on wireless local area network, user equipment, and access point

A method for transmitting data on a wireless local area network, the method comprising:

• determining first indication information, wherein the first indication information is used to indicate that user equipment (UE) can preferentially send data to an access point (AP) when the UE obtains a transmission resource through contention;
• sending the first indication information to the UE, so that the UE determines, according to the first indication information, a first moment for sending current data, wherein an interval between a second moment at which the AP sends a first feedback message for indicating whether a previous piece of data is successfully received and the first moment is a first sending interval, and the first sending interval is less than a distributed interframe space (DIFS);
• and
• receiving the current data that is sent at the first moment by the UE.

User equipment (UE), comprising:

• a receiving module, configured to receive first indication information sent by an access point (AP), wherein the first indication information is used to indicate that the UE can preferentially send data to the AP when the UE obtains a transmission resource through contention;
• a determining module, configured to determine, according to the first indication info/nation received by the receiving module, a first moment for sending current data to the AP, wherein an interval between a second moment at which the UE receives a first feedback message sent by the AP and the first moment is a first sending interval, the first feedback message is used to indicate whether the AP has successfully received a previous piece of data sent by the UE, and the first sending interval is less than a distributed interframe space (DIFS);
• and
• a sending module, configured to send the current data to the AP at the first moment determined by the determining module.

An access point (AP), comprising:

• a determining module, configured to determine first indication information, wherein the first indication information is used to indicate that user equipment (UE) can preferentially send data to the AP when the UE obtains a transmission resource through contention;
• a sending module, configured to send the first indication information determined by the determining module to the UE, so that the UE determines, according to the first indication information, a first moment for sending current data, wherein an interval between a second moment at which the AP sends a first feedback message for indicating whether a previous piece of data is successfully received and the first moment is a first sending interval, and the first sending interval is less than a distributed interframe space (DIFS);
• and
• a receiving module, configured to receive the current data that is sent by the UE at the first moment determined according to the first indication information sent by the sending module.
