Solution Overview

Problem

Conventional wireless communications networks face challenges in efficiently handling multicast or broadcast transmissions, particularly in supporting a wide range of devices with varying data traffic profiles and latency tolerances, leading to inefficiencies in resource allocation and control information transmission.

Innovation Solution

A method for selecting and independently encoding control information with different priorities for transmission using subsets of uplink communication resources, allowing for efficient multiplexing and reliable delivery of control information even in overlapping resource scenarios.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multicast or broadcast transmissions are used to support a wide range of devices with varying data traffic profiles, then device coverage and service versatility are improved, but resource allocation efficiency and control information transmission reliability deteriorate

Engineering Contradiction:
Improvedevice coverageVSAvoidcontrol information transmission reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments control information into multiple priority levels (first priority, second priority, etc.) and allocates different uplink communication resources for transmitting control information of different priorities. This segmentation allows the system to maintain reliable transmission for high-priority control information while efficiently utilizing resources for lower-priority transmissions, thereby resolving the contradiction between supporting diverse devices and maintaining transmission reliability.

Inventive Principle:
Principle #1Segmentation

2Productivity

If control information is transmitted using shared uplink communication resources, then resource utilization efficiency is improved, but transmission reliability for high-priority data deteriorates

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidhigh-priority data transmission reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies local quality by assigning different quality levels (priorities) to different control information and allocating resources accordingly. High-priority control information is transmitted using dedicated or prioritized resources ensuring reliability, while lower-priority information shares resources to maximize utilization efficiency. This localized differentiation of resource quality resolves the contradiction between resource efficiency and high-priority transmission reliability.

Inventive Principle:
Principle #3Local quality

3Quantity of substance

If uplink communication resources are allocated for multiple control information transmissions, then control information coverage is improved, but resource collision and interference increase

Engineering Contradiction:
Improvecontrol information coverageVSAvoidresource collision
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces dynamic resource allocation where the network device can adjust the allocation of uplink communication resources based on the priority of control information and current channel conditions. When resource collisions are detected or anticipated, the system dynamically reassigns resources to ensure high-priority control information transmissions are not affected, while still maintaining coverage for multiple control information types. This dynamic adjustment resolves the contradiction between coverage and collision avoidance.

Inventive Principle:
Principle #15Dynamics
