PUR Release Counter Synchronization in Wireless Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, misalignment of preconfigured uplink resource (PUR) release counters between user equipment (UE) and base stations can lead to premature release of PURs, causing interference and reducing the success of UE transmissions, which wastes computing resources and affects transmission efficiency.
Innovation Solution
Synchronizing the PUR release counter values between UE and base stations, particularly during connected mode transitions or reconfiguration, to ensure aligned counter values, preventing premature release and improving transmission reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the PUR release counter is incremented independently by UE and base station without synchronization, then the PUR release mechanism can operate autonomously at each end, but the counter values may misalign causing premature release and transmission failures
Solution Approach 1:
The patent implements feedback mechanisms where the UE reports its PUR release counter value to the base station, and the base station provides feedback on the PUR release counter status. This allows both ends to synchronize their counter values and maintain alignment while preserving autonomous operation capabilities.
Solution Approach 2:
The patent introduces an intermediary synchronization mechanism that mediates between the UE's autonomous counter increment and the base station's PUR release decisions. Through structured feedback exchanges, the intermediary protocol ensures both ends reach consistent counter values without centralizing control.
2Productivity
If the base station releases PUR when its counter reaches maximum value, then PUR resources can be reallocated efficiently, but the UE may continue using the PUR causing interference and wasted computing resources
Solution Approach 1:
The patent employs feedback where the base station communicates PUR release status and counter values to the UE. When the base station releases a PUR due to counter maximum, the UE receives this feedback and同步 its counter value, preventing continued use of released resources and eliminating interference.
Solution Approach 2:
The patent implements preliminary synchronization actions where the UE and base station exchange counter information before PUR release decisions are finalized. This preliminary alignment prevents the scenario where the base station releases resources while the UE continues using them.
3Duration of action of moving object
If PUR transmissions are attempted without counter synchronization, then the UE can maintain continuous transmission capability, but transmission success rate decreases due to premature release and interference
Solution Approach 1:
The patent maintains continuous PUR transmission capability through periodic feedback exchanges that keep counter values synchronized. This allows the UE to continuously use PUR resources without interruption while ensuring transmission success by preventing premature release scenarios.
Solution Approach 2:
The patent uses feedback mechanisms to continuously monitor and synchronize PUR release counter values between UE and base station. This feedback ensures transmission reliability by aligning both ends' understanding of PUR validity, preventing failed transmissions due to counter misalignment.

AI summary
A method, an apparatus, and a computer program product for wireless communication are provided. Aspects described herein provide techniques and apparatuses associated with synchronizing a preconfigured uplink resource (PUR) release counter between a base station and a user equipment (UE). For example, the synchronization may be performed in connection with the UE entering a connected mode, the base station reconfiguring a PUR, and/or the like. By synchronizing the PUR release counter, misalignment of the PUR release counter between the UE and the base station may be reduced or eliminated. Reducing the misalignment of the PUR release counter reduces the occurrence of a premature release of a PUR, thus reducing UE interference and improving the likelihood of success of the UE's transmission.
