specific Embodiment 1

[0057] The communication method of the wireless local area network further includes: before performing the receiving of the data frame in step 202, negotiating with the sender device whether the contents of the data frames simultaneously sent in the multiple frequency bands are the same.

[0058] That is to say, it is a method of negotiating in advance before sending a data frame, and knowing in advance whether the content of the data frames sent by the sender device at the same time in multiple frequency bands is the same, so as to directly enter the generation of the corresponding confirmation message after receiving the data frame. Frame operation steps; for example, the above negotiation is performed during the process of establishing the initial communication connection between the two parties.

specific Embodiment 2

[0060] The communication method of the wireless local area network further includes: acquiring a content identifier included in a frame header of the data frame, where the content identifier is used to indicate the data sent by the sender device simultaneously in the multiple frequency bands. Whether the contents of the data frames are the same; when the content identifier is a third value, it is determined that the contents of the data frames simultaneously sent by the sender device in the multiple frequency bands are the same; when the content identifier is When the fourth value is used, it is determined that the contents of the data frames simultaneously sent by the sender device in the multiple frequency bands are different.

[0061] That is to say, after receiving the data frame, parse and obtain the content identifier contained in the frame header of the data frame, so as to determine, according to the specific value of the content identifier, the data frame sent by the s...

specific Embodiment 3

[0078] When it is determined that the contents of the data frames simultaneously sent by the sender device in the multiple frequency bands are different, the step 204 specifically includes:

[0079] Determine whether the data frames transmitted under each frequency band of the plurality of frequency bands are respectively correctly received results, and set the information identification bit corresponding to each result in the acknowledgment message frame.

[0080] In this embodiment, when the contents of the data frames transmitted in multiple frequency bands are different, in order to complete and comprehensively feed back to the sender device the reception situation of the data frames transmitted simultaneously in each frequency band of the multiple frequency bands , it is necessary to confirm whether the data frame respectively transmitted under each frequency band of the multiple frequency bands is correctly received, and reflect the receiving result corresponding to each ...

Abstract

The invention provides a communication method and device of a wireless local area network and communication equipment, and the communication method of the wireless local area network comprises the steps: receiving data frames sent by sender equipment at the same time under a plurality of frequency bands; generating an acknowledgement message frame corresponding to the data frame wherein the acknowledgement message frame comprises an information identification bit used for indicating the receiving state of the data frame; when the information identification bit is a first value, indicating that the data frame is correctly received, and when the information identification bit is a second value, indicating that the data frame is not correctly received; and feeding back the acknowledgement message frame to the sender equipment under any frequency band in the plurality of frequency bands. According to the technical scheme, the frequency spectrum utilization rate can be effectively improvedso as to improve the communication efficiency, and meanwhile power saving of equipment is facilitated.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a communication method for a wireless local area network, a communication device for a wireless local area network, and a communication device. Background technique [0002] In July 2018, IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.11 established the next-generation Wi-Fi (Wireless Fidelity, wireless network) technology research group EHT (Extreme High Throughput, extremely high throughput, extremely high throughput) ), which mainly studies how to improve the throughput of the next-generation Wi-Fi technology, so that it has a higher throughput than the existing Wi-Fi technology, requires a larger bandwidth, such as 320MHz, or requires more data streams For example, the maximum number of data streams can be 16, and in order to further improve the throughput, the related technology proposes t...
