HS-RACH Resource Release Signaling for Uplink Channel Reallocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies lack a method for releasing High-Speed Random Access Channel (HS-RACH) resources, leading to continuous occupation and incomplete procedures when replacing Random Access Channels (RACHs) for uplink transmission.
Innovation Solution
A method for releasing HS-RACH resources involves obtaining trigger information, determining to release allocated resources based on this information, and explicitly signaling the release, using physical-layer signaling or layer-2 control protocols, to manage resource utilization effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If HS-RACH resources are allocated for uplink transmission, then uplink transmission efficiency is improved, but resources remain occupied indefinitely and cannot be released
Solution Approach 1:
The patent introduces dynamic resource management by implementing a release mechanism that allows HS-RACH resources to be allocated and released based on actual transmission needs. The network equipment sends release indications to UE to free up resources when no longer needed, transforming the static resource occupation into a dynamic state that adapts to changing transmission requirements.
Solution Approach 2:
The patent enables the network to discard (release) HS-RACH resources when they are no longer needed for uplink transmission. The release indication mechanism allows the network equipment to notify UE of resource release, and the UE subsequently recovers these resources for other uses, improving overall resource utilization efficiency.
2Duration of action of moving object
If HS-RACH resources are continuously occupied, then uplink transmission can proceed without interruption, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements periodic resource management through the release indication mechanism. Instead of continuous occupation, resources are allocated for specific transmission periods and then released, creating a periodic pattern of allocation and release that improves resource utilization while maintaining continuous transmission capability through re-allocation when needed.
3Reliability
If a resource release mechanism is added, then resource management completeness is improved, but system complexity increases
Solution Approach 1:
The patent extracts the resource release function as a separate, independent mechanism from the existing HS-RACH allocation process. By introducing a dedicated release indication message and separate release procedure, the system adds completeness to resource management without significantly complicating the core uplink transmission mechanism, allowing both functions to operate independently.
Data Source
AI summary
A method, a UE and a communications system for releasing resources are disclosed. When the UE is in a CELL_FACH state, a resource release indication is transmitted from a network equipment to the UE to instruct the UE to release HS-RACH resources on the UE. Upon receiving the resource release indication, the UE releases previously allocate HS-RACH resources on the UE.
