Embodiment 1

[0040] This embodiment takes the redesigned wireless frame actively initiated as an example.

[0041] It is assumed that the access point AP-1 has established a basic service set, and the STA-1 has been associated with the AP-1.

[0042] STA-1 sends a wireless frame to AP-1. This wireless frame is a short wireless frame without physical layer frame load, which carries the load information of the original wireless frame with the same function into the physical layer frame header signaling domain. A wireless frame, specifically, the wireless frame only includes three fields: a short training sequence field, a long training sequence field, and a signaling field, wherein the N bits in the signaling field are dedicated to frame type indication, indicating that the wireless frame The specific value of the N bits indicates the specific function of the wireless frame. The N bits can be the bits of the MCS subfield. The first address information subfield in the signaling field occupies...

Embodiment 2

[0047] This preferred embodiment 2 takes requesting feedback of channel measurement information as an example to describe that a station receives a wireless frame from an access point through a brief message transfer.

[0048] When performing closed-loop transmission, such as Beamforming transmission, the initiator Beamformer needs to know the channel information between it and the receiver Beamformee, then the Beamformee needs to perform channel measurement and feed back the channel measurement information to the Beamformer. If the Beamformee performs channel measurement If there is no immediate feedback, or the channel measurement feedback information received by the Beamformer is wrong, the Beamformer will send a beamforming report poll (Beamforming Report Poll) frame, requesting the Beamformee to feed back all channel measurement information or the channel measurement information that the Beamformer failed to receive correctly part. figure 2 is a schematic diagram of the ...

Embodiment 3

[0055] This preferred embodiment 2 takes requesting feedback of channel measurement information as an example to describe that a station receives a wireless frame from an access point through a brief message transfer. The difference between the third preferred embodiment and the second preferred embodiment is that the station only determines whether the information carried in the second address information subfield matches itself.

[0056] When performing closed-loop transmission, such as Beamforming transmission, the initiator Beamformer needs to know the channel information between it and the receiver Beamformee, then the Beamformee needs to perform channel measurement and feed back the channel measurement information to the Beamformer. If the Beamformee performs channel measurement If there is no immediate feedback, or the channel measurement feedback information received by the Beamformer is wrong, the Beamformer will send a beamforming report poll (Beamforming Report Poll)...

Abstract

The invention discloses a wireless frame processing method and system. The method comprises the following steps: a wireless frame is sent by a sender to a receiver, wherein the sender is a site at which basic services are centralized and the receiver is an access point at which basic services are centralized or the sender is an access point at which basic services are centralized and the receiver is a site at which basic services are centralized, a first address information subdomain and a second address information subdomain are carried in a physical frame header signaling domain of the wireless frame, the first address information subdomain is used to identify the access point, and the second address information subdomain is used to identify the site; and the receiver is used to determine that the wireless frame is a wireless frame sent to itself according to the first address information subdomain and / or the second address information subdomain. According to the invention, the waste of address information subdomains can be avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless frame processing method and system. Background technique [0002] Currently, in the field of wireless networks, a wireless local area network (Wireless Local Area Network, WLAN for short) develops rapidly, and the global demand for WLAN coverage is increasing day by day. The Institute for Electrical and Electronic Engineers (referred to as IEEE) industry specification 802.11 working group has defined a series of WLAN technical standards such as 802.11a, 802.11b, 802.11g, and mainly formulated the Physical Layer Protocol (Physical Layer Protocol, Referred to as PHY) and Media Access Control (Media Access Control, referred to as MAC) layer specification. Subsequently, other task groups emerged, dedicated to the development of specifications involving the improvement of existing 802.11 technologies. For example, the 802.11ah task group mainly focuses on the utilization ...
