Solution Overview

Problem

The existing solution for uplink transmission using enhanced high-speed random access channels (HS-RACHs) lacks a method for releasing HS-RACH resources, leading to continuous occupation and incomplete procedure.

Innovation Solution

A method for releasing HS-RACH resources is introduced, involving obtaining trigger information, determining to release allocated resources, and explicitly signaling the release, using physical-layer signaling, layer-2 control protocol data units, or other methods, to free up resources when conditions such as low data buffer usage, cell handover, or quality of service requirements are met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If HS-RACH resources are allocated for uplink transmission, then uplink transmission capability is improved, but resource occupation continues indefinitely without release mechanism

Engineering Contradiction:
Improveuplink transmission capabilityVSAvoidresource occupation
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic resource management by introducing trigger information that monitors buffer usage, cell handover status, and QoS requirements. Resources are released dynamically when conditions change, transforming the static resource allocation into a dynamic system that adapts to current network conditions and user needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback mechanism where trigger information is continuously monitored and fed back to the release determination module. This feedback loop enables the system to automatically detect when resources should be released based on buffer usage thresholds, handover events, or QoS changes, creating a closed-loop control system for resource management.

Inventive Principle:
Principle #23Feedback

2Loss of energy

If resource release mechanism is added, then resource utilization is optimized, but procedure complexity increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidprocedure complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent configures release trigger information and thresholds in advance before resource allocation occurs. The system pre-defines the conditions under which resources should be released, so that when allocation happens, the release criteria are already established. This preliminary configuration simplifies the actual release decision-making process during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically monitors trigger information and determines resource release without requiring external intervention or complex manual procedures. The release determination module autonomously evaluates conditions against predefined criteria and executes release decisions, enabling the system to manage its own resources self-service style.

Inventive Principle:
Principle #25Self-service
