Embodiment 1

[0076] figure 2 It is a schematic flow chart of Embodiment 1 of the method for sending a control frame in the present invention. In this embodiment, in one BSS, there are three stations: AP, STA1 and STA2. The method includes the following steps:

[0077] In step 201, the AP predefines the queue category AC_VO as the queue category for transmitting NDPA.

[0078] Step 202, when there is no traffic among the three stations for a certain period of time, and the AP has no channel information of STA1 and STA2 or the measured channel information of STA1 and STA2 is invalid, the queue type AC_VO competes for the channel.

[0079] Step 203, the AP sends NDPA on the channel that uses the queue category AC_VO to compete for, and performs channel information measurement of STA1 and STA2;

[0080] Specifically, after competing for the channel, send NDPA on the channel that uses the queue category AC_VO to compete for the channel information measurement of STA1 and STA2; here, the subse...

Embodiment 2

[0082] image 3 It is a schematic flow diagram of Embodiment 2 of the method for sending a control frame in the present invention. In this embodiment, in one BSS, there are six stations: APs and five STAs. The method includes the following steps:

[0083] In step 301, the AP predefines the queue category AC_VI as the queue category for transmitting NDPA.

[0084] Step 302, when there is no traffic between the AP and each station for a certain period of time, and the AP does not have channel information of each STAs or the channel information has expired, the queue category AC_VI competes for the channel.

[0085] Step 303, the AP sends NDPA on the channel that uses the queue category AC_VI to compete for, and performs channel information measurement of five stations;

[0086] Specifically, after competing for the channel, NDPA is sent on the channel that the queue category AC_VI competes for, and is used to measure the channel information of the five stations; here, the subse...

Embodiment 3

[0088] Figure 4 It is a schematic flow diagram of Embodiment 3 of the method for sending a control frame in the present invention. In this embodiment, in one BSS, there are three stations: AP, STA1 and STA2. The method includes the following steps:

[0089] In step 401, the AP predefines the queue category AC_VI as the queue category for transmitting NDPA.

[0090] Step 402, the queue category AC_VI of the AP has the data of the target station STA1, and the queue category AC_VI competes for the channel. When the AP does not have the channel information of the target station STA1, it sends NDPA on the channel that the queue category AC_VI has competed for, and the target station STA1 channel information measurement;

[0091] Specifically, the queue category AC_VI of the AP has the data of the target station STA1, and the queue category AC_VI competes for the channel at this time; after the queue category AC_VI competes for the channel, if the AP has the channel information of...

Abstract

The invention discloses a method for sending a control frame, including: when performing channel information measurement, sending the control frame by using a specific queue type and / or a queue type competing for a channel; the invention also provides a device for sending the control frame. According to the technical solution of the present invention, the control frame can be sent when performing channel information measurement.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for sending a control frame. Background technique [0002] At present, in the field of wireless networks, Wireless Local Area Networks (WLAN, Wireless Local Area Networks) are developing rapidly, the demand for WLAN coverage is also increasing, and the requirements for throughput are also getting higher and higher. In the IEEE802.11 group of the industry specification of the American Institute of Electrical and Electronics Engineers, a series of standard WLAN technologies such as 802.11a, 802.11b, and 802.11g have been defined successively; 802.11 technology improvement specification, for example, the 802.11n task group puts forward the requirement of high throughput (HT, High Throughput), which can support the data rate up to 600Mbps, and the 802.11ac task group further proposes the concept of gigabit throughput (VHT, Very High Throughput) , by ...
