Group-Based Signaling for Wireless Access Network Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless access networks, such as those based on IEEE802.11ax, fail to meet the low latency and low jitter requirements of real-time applications (RTAs), and the increased signaling overhead from a large number of RTA services negatively impacts communication efficiency.
Innovation Solution
A communication method and apparatus that generate and transmit a first message frame with group indication information, triggering device groups to perform data transmission, thereby reducing signaling overhead and improving communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of RTA services are supported in the wireless access network, then the service coverage and capacity are improved, but the signaling overhead increases and communication efficiency deteriorates
Solution Approach 1:
The patent combines multiple individual service requests into a single group-based service request. Instead of processing each RTA service separately with individual signaling, the system groups multiple services together and processes them as one unit, thereby reducing the total signaling overhead while maintaining support for multiple services.
Solution Approach 2:
The patent introduces a universal group-based signaling mechanism that can handle multiple different RTA services through a single standardized process. This multi-functional approach allows the same signaling framework to serve various service types (video, audio, gaming, etc.) without requiring separate signaling paths for each service.
2Measurement precision
If individual service processing is used for each RTA service, then service specificity and precision are improved, but the signaling overhead increases and communication efficiency deteriorates
Solution Approach 1:
The patent merges multiple individual service processing operations into a single group-based processing operation. By combining service requests, acknowledgments, and resource allocations into group-level operations, the system maintains service specificity through group identifiers while dramatically improving communication efficiency by reducing the number of individual signaling exchanges.
3Ease of operation
If traditional wireless access network protocols are used, then system simplicity and ease of operation are maintained, but the latency and jitter requirements of RTA services are not met
Solution Approach 1:
The patent introduces dynamic group-based resource allocation and scheduling mechanisms that adapt to real-time service requirements. Instead of static protocol operations, the system dynamically forms service groups, allocates resources based on group priorities, and adjusts scheduling in real-time, thereby meeting latency and jitter requirements while building upon existing protocol frameworks.
Solution Approach 2:
The patent implements preliminary group formation and resource allocation before actual service data transmission begins. By pre-establishing service groups and allocating resources in advance, the system reduces latency during actual service operation while maintaining protocol simplicity, as the complex setup work is completed beforehand.

AI summary
Embodiments of this application provide a communication method and apparatus, a computer-readable medium, and an electronic device. The communication method includes: generating a first message frame, the first message frame including group indication information of an access device, and the group indication information being configured for indicating information about a device group that performs data transmission after a transmission of the first message frame and the device group including one or more access devices; and transmitting the first message frame to the device group, to trigger the one or more access devices in the device group indicated by the group indication information to perform the data transmission.
