Unified ACK Feedback Policy for Multi-Connection QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IEEE 802.11 standards lack ACK feedback policies for transmitting Quality of Service (QoS) data frames through multiple connections, which is necessary for devices communicating in multiple frequency bands, impacting latency and throughput.
Innovation Solution
Configuring a unified ACK feedback policy for data frames transmitted through multiple connections using a same traffic identifier (TID), allowing devices to communicate across different frequency bands, thereby reducing latency and improving network throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If QoS data frames are transmitted through multiple connections to improve throughput, then network throughput is improved, but the complexity of ACK feedback policy management increases
Solution Approach 1:
The patent merges the ACK feedback policies for multiple connections into a unified policy. When data frames with the same TID are transmitted through multiple connections, a single target ACK feedback policy is applied to all connections, consolidating what would otherwise require separate policies for each connection. This reduces management complexity while maintaining the throughput benefits of multi-connection transmission.
Solution Approach 2:
The patent creates a universal ACK feedback policy that can be applied across multiple connections simultaneously. The target ACK feedback policy is designed to work universally for all connections carrying data frames with the same TID, eliminating the need to design and manage separate ACK policies for each individual connection.
2Measurement precision
If ACK feedback policies are configured for each connection to ensure accurate receiving state determination, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the receiving state determination process across multiple connections by applying a single target ACK feedback policy to all connections. The receiving terminal determines the receiving state for data frames transmitted through multiple connections using this unified policy, maintaining measurement precision while reducing configuration complexity.
3Speed
If multiple ACK feedback policies are maintained for different connections to support low latency transmission, then transmission speed is improved, but the loss of time for policy negotiation increases
Solution Approach 1:
The patent performs preliminary action by pre-configuring the target ACK feedback policy to be applicable across multiple connections before data transmission begins. This eliminates the need for separate policy negotiations for each connection during data transmission, reducing the time lost to policy negotiation while maintaining the speed benefits of multi-connection transmission.
4Ease of operation
If a unified ACK feedback policy is applied across multiple connections to reduce complexity, then ease of operation is improved, but the precision of individual connection feedback may be reduced
Solution Approach 1:
The patent applies local quality by allowing the unified target ACK feedback policy to be selectively applied based on the TID. Each TID can have its own target ACK feedback policy configured, meaning that while the policy is unified at the connection level, it maintains local precision at the TID level. This enables easy operation through unified policy management while preserving precision through TID-specific policy configurations.

AI summary
The present disclosure provides a method and apparatus for configuring an acknowledge (ACK) feedback policy, and a method and apparatus for an acknowledge (ACK) feedback. The method for configuring the ACK feedback policy includes: in response to that first data frames corresponding to a same traffic identifier (TID) are to be transmitted to a receiving terminal through multiple connections, configuring ACK feedback policies for second data frames transmitted through respective connections in the multiple connections as a same target ACK feedback policy, wherein the second data frames are at least the same as a part of the first data frames; and transmitting the second data frames to the receiving terminal through the respective connections.
