Unified Frame Transmission for Multiband Radio Resource Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless local area networks face challenges in radio resource management across different bands, leading to conflicts and low utilization due to separate management of bands and contention-based access, especially when multiple stations attempt to access the same access point.
Innovation Solution
A frame transmission method that schedules radio resources across multiple bands in a unified manner, using indication information to coordinate radio operation parameters, such as frequency, time, and space domain resources, to avoid conflicts and improve utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate radio resource management is performed in different bands based on BSSs, then each band can be managed independently, but radio resource utilization is low and conflicts occur when multiple STAs access the same AP
Solution Approach 1:
The patent merges radio resource management across multiple bands by allowing an AP to send TWT element information containing resource parameters for multiple bands simultaneously. This enables unified scheduling of STAs across different bands, transforming separate band management into integrated resource allocation that improves utilization while maintaining flexibility.
Solution Approach 2:
The TWT element information structure is designed to carry resource parameters for multiple bands universally. A single TWT element can specify frequency, time, and space domain resources across different bands, enabling the same mechanism to handle resource management in multiple bands rather than requiring separate management procedures for each band.
2Ease of operation
If multiple STAs access the same AP based on contention mechanism, then access is simple and decentralized, but conflicts occur and radio resource utilization decreases
Solution Approach 1:
The patent implements preliminary scheduling by having the AP pre-allocate TWT resources to STAs before actual data transmission. The TWT element information contains pre-configured resource parameters (frequency, time, space domain) that STAs can use without contention, eliminating conflicts while maintaining ease of access through simple scheduled transmission.
Solution Approach 2:
The TWT mechanism enables dynamic resource allocation where the AP can adjust resource parameters for different STAs and bands based on current network conditions. This dynamic scheduling allows the system to adapt resource distribution in real-time, improving utilization while keeping the access mechanism simple for STAs.

AI summary
This application provides a frame transmission method and a device. The method includes: generating, by a first device, a first frame, where the first frame carries indication information, and the indication information is used to indicate radio operation parameters of a first band; and sending, by the first device, the first frame to a second device in a second band. The method is applicable to scheduling, in a band, a radio resource in another band in a multiband communications system.
