Problems solved by technology

[0007] (1) Low spectrum utilization and unstable scheduling information
[0008] (2) In the existing technology, it is not possible to make better use of 6G frequency band resources for data transmission in the existing technology environment to achieve higher spectrum utilization; it is not possible to accurately send low-scheduling information
[0009] Scheduling information cannot reduce scheduling overhead, and cannot accurately detect error probability through sequence codes
[0010] (3) In the prior art, each user needs to send IE separately, and multi-user uplink and downlink cannot be scheduled simultaneously
[0011] (4) In the prior art, only the main channel of the 2.4G / 5GHz frequency band is used to send the multi-band information unit. When the 2.4G / 5GHz frequency band is busy, the multi-band information unit cannot be sent in time
[0012] (5) In the prior art, packet loss of multi-band information units may occur
[0014] The existing technology cannot solve the above problems, and a more flexible multi-band information transmission mode is required

Embodiment 1

[0059] Centralized coordination, including:

[0060] 1. The main AP is selected, and other APs enter the STA state, and send Action frames on the main AP channel to inform the main AP of their respective main channels (the main AP chooses a temporary channel, and other APs send Action frames to the main AP on the temporary channel to inform each other) main channel). The main AP receives the main channel information of each AP, and according to the main channel occupancy of each AP, selects a 20M fragmented frequency band in the 2.4G frequency band as the protection channel for each AP to send 6G scheduling information, and allocates the protection channel usage time for each AP . Then encapsulate the above information in an Action frame, and reply to each AP for confirmation, such as Figure 4-Figure 5 shown. After receiving relevant information, other APs reply to the main AP for confirmation, and switch to their own main channel again.

[0061] Other APs reply ACK to th...

Abstract

The invention belongs to the technical field of information processing, and discloses a 6G scheduling information protection method and system, and the method comprises the steps: setting a 6G scheduling information protection channel in a 2.4 G frequency band, and enabling different APs to periodically utilize the protection channel to transmit redundant scheduling information; trigger frame utilization HE- SIG If the B field schedules 2.4 G downlink, 6G uplink and downlink scheduling information is packaged into a Trigger frame load part; if the Trigger frame schedules 2.4 G uplink, packaging 6G uplink and downlink scheduling information in the HE-; sIG A part B; and after the same sequence code is received again in the 6G frequency band, uplink transmission is carried out. According to the method, 2.4 G uplink and downlink scheduling information and 6G uplink and downlink scheduling information are simultaneously contained in the Trigger frame, the scheduling overhead is reduced,the 6G uplink scheduling information comprises the trigger sequence code, the sequence code detection error probability is low, and the error rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a 6G scheduling information protection method and system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Before 802.11ax, the MAC access mechanism was a typical CSMA mechanism (that is, CSMA / CA used in DCF). After the introduction of OFDMA requirements, the MAC layer random access mechanism of 802.11ax has also changed. In the protocol, instead of the traditional CSMA idea, WLAN (Wireless Local Area Network, wireless local area network) generally adopts TF (Trigger Frame, trigger frame) random access mode. [0004] current technology: [0005] A multiband information element (IE) indicating the status of the 60GHz band is transmitted on the 2.4 / 5GHz band. The multi-band IE helps to perform multi-band handover. [0006] In summary, the problems in the prior art are: [0007...
