Solution Overview

Problem

Conventional wireless communications networks face challenges in efficiently handling multicast or broadcast transmissions, particularly in managing acknowledgement information with varying priorities and resource allocations, leading to potential delays or loss of control information.

Innovation Solution

A method for independently encoding and transmitting control information with different priorities using separate subsets of uplink communication resources, allowing for efficient multiplexing without compromising reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If control information with different priorities is transmitted using shared uplink resources, then resource utilization is improved, but reliability of high-priority control information deteriorates due to potential collisions and multiplexing conflicts

Engineering Contradiction:
Improveresource utilizationVSAvoidreliability of control information transmission
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent segments uplink communication resources into multiple distinct sets, where each set is dedicated to transmitting control information of a specific priority level. This segmentation prevents collisions between different priority control information while maintaining high resource utilization by fully utilizing each dedicated resource set for its intended purpose without multiplexing conflicts.

Inventive Principle:
Principle #1Segmentation

2Productivity

If control information is transmitted using multiplexing techniques, then resource efficiency is improved, but complexity of resource management increases

Engineering Contradiction:
Improveresource efficiencyVSAvoidcomplexity of resource management
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides uplink resources into separate dedicated sets for different priority levels, eliminating the need for complex multiplexing management. Each priority level has its own resource set, simplifying the resource management process while maintaining high efficiency through parallel transmission capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different resource allocation strategies to different priority levels, with high-priority control information receiving dedicated protected resources while lower-priority information utilizes other resource sets. This local differentiation optimizes resource efficiency for each priority level without requiring complex global multiplexing management.

Inventive Principle:
Principle #3Local quality

3Reliability

If acknowledgement information is transmitted with high reliability, then transmission accuracy is improved, but transmission time increases due to additional redundancy and confirmation protocols

Engineering Contradiction:
Improvetransmission accuracyVSAvoidtransmission time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments uplink resources into dedicated sets for different priority levels, allowing high-priority acknowledgement information to be transmitted immediately on dedicated resources without waiting for multiplexing opportunities or additional confirmation protocols. This segmentation ensures high transmission accuracy while minimizing transmission time by eliminating unnecessary delays.

Inventive Principle:
Principle #1Segmentation
