Embodiment Construction

[0045] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0046] Figure 4 It is a flowchart of a method for sending service indication information according to an embodiment of the present invention. Such as Figure 4 As shown, the method mainly includes the following processing:

[0047] Step S402: The AP sets an indication field in the wireless frame, wherein the indication field is used to indicate whether the wireless frame carries virtual bitmap information of service indication;

[0048] Step S404: the AP sends wireless frames to multiple STAs associated with the AP.

[0049] In the related art, it is not considered how to instruct multiple non-access stations when the AP has no unicast buffer data of any station. use as Figure 4 In the method...

Abstract

The present invention discloses a method and device for sending service indication information. In the above method, an AP sends a wireless frame to multiple STAs associated with the AP, wherein the wireless frame carries an indication field, and the indication field is used for Indicates whether the radio frame carries virtual bitmap information of service indication. According to the technical solution provided by the present invention, when the AP has no unicast buffer data of any station, multiple STAs associated with the AP can know whether there is their own unicast buffer data waiting to be sent in the AP.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending service indication information. Background technique [0002] At present, in the field of wireless networks, with the rapid development of wireless local area networks (WLANs), the application range of WLANs is expanding day by day. In response to various network requirements, the IEEE802.11 group of the Institute of Electrical and Electronics Engineers issued a series of the most common WLAN technical standards such as 802.11ah, 802.11b, 802.11g, and 802.11n. Subsequently, other task groups were established one after another, dedicated to the development of specifications related to the improvement of existing 802.11 technologies. For example, with the development of the Internet, IEEE established the 802.11ah task group, whose main task is to media access control (MAC) of WLAN ) layer and physical (PHY) layer are modified and enhanced in order ...
