Abstract

This application relates to the field of wireless communications. In an embodiment, a data transmission method comprises generating, by an access point (AP), a scheduling frame, wherein the scheduling frame comprises a first user information field that carries first trigger information for one or more first stations (STAs) and a second user information field that carries second trigger information for one or more second STAs; sending, by the AP, the scheduling frame, wherein the scheduling frame further comprises a field indicating the scheduling frame is an extension scheduling frame, the extension scheduling frame has a trigger frame type that complies with a protocol later than the 802.11ax standard protocol.

Claims24

Dependent claims

A data transmission method for wireless local area networks, the method comprising:

generating, by an access point (AP), a scheduling frame comprising a first subframe that comprises a first trigger frame and a second subframe that comprises a second trigger frame, wherein the first trigger frame comprises a first user information field that carries first trigger information for one or more first stations (STAs) and a trigger frame type extension field indicating that the first trigger frame complies with a protocol later than a 802.11ax standard protocol, wherein the second trigger frame comprises a second user information field that carries second trigger information for one or more second STAs, wherein the first trigger information schedules the one or more first STAs to perform uplink data transmission on a first part of a channel, the second trigger information schedules the one or more second STAs to perform uplink data transmission on a second part of the channel, and the first part of the channel does not overlap with the second part of the channel in frequency, and wherein the one or more first STAs comply with the protocol later than the 802.11ax standard protocol, and the one or more second STAs comply with the 802.11ax standard protocol;
and
sending, by the AP, the scheduling frame.

An apparatus in wireless local area networks comprising:

at least one processor;
and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
generating a scheduling frame comprising a first subframe that comprises a first trigger frame and a second subframe that comprises a second trigger frame, wherein the first trigger frame comprises a first user information field that carries first trigger information for one or more first stations (STAs) and a trigger frame type extension field indicating that the first trigger frame complies with a protocol later than a 802.11ax standard protocol, wherein the second trigger frame comprises a second user information field that carries second trigger information for one or more second STAs, wherein the first trigger information schedules the one or more first STAs to perform uplink data transmission on a first part of a channel, the second trigger information schedules the one or more second STAs to perform uplink data transmission on a second part of the channel, and the first part of the channel does not overlap with the second part of the channel in frequency, and wherein the one or more first STAs comply with the protocol later than the 802.11ax standard protocol, and the one or more second STAs comply with the 802.11ax standard protocol;
and
sending the scheduling frame.
