HS-RACH Resource Release Triggers for Uplink Channel Occupancy
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Loss of energy
If resource release mechanism is added, then resource utilization is optimized, but procedure complexity increases
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.
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.
