PUR Search Space Window Overlap Resolution with SMTC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR system, there is a resource conflict between the Preconfigure Uplink Resource (PUR) search space window and the SS block based RRM Measurement Timing Configuration (SMTC) in the time domain, which prevents the UE from transmitting or receiving data simultaneously.
Innovation Solution
A method is provided to determine whether the PUR search space window and the SMTC overlap in time domain, and in case of an overlap, the UE either transmits uplink data through the associated PUR or performs a measurement in the SMTC according to the measurement requirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE monitors PDCCH in the PUR search space window to receive downlink data, then the UE can receive downlink data efficiently, but the resource conflicts with SMTC measurement timing causing measurement failures
Solution Approach 1:
The patent implements dynamic adjustment of the PUR search space window based on SMTC measurement timing. When SMTC measurement is required, the PUR search space window is dynamically shifted or adjusted to avoid overlapping with the SMTC measurement window, allowing the system to adapt between data reception and measurement modes
Solution Approach 2:
The patent performs preliminary determination of whether PUR search space window and SMTC measurement window overlap before actual operations. Based on this preliminary assessment, the system proactively adjusts the PUR search space window configuration to prevent conflict, ensuring both data reception and measurement can proceed without interference
2Reliability
If the UE performs SMTC measurement, then the UE can perform radio resource management measurement, but the resource conflicts with PUR search space window causing data transmission interruption
Solution Approach 1:
The system dynamically adjusts the PUR search space window timing based on SMTC measurement requirements. When measurement is prioritized, the search space window is shifted to a different time slot, allowing measurement to proceed without interrupting potential future data transmissions
Solution Approach 2:
The system performs preliminary overlap detection between PUR search space window and SMTC measurement window. When overlap is detected, the PUR window is proactively adjusted before measurement begins, preventing data transmission interruptions while ensuring measurement can be completed
3Device complexity
If the PUR search space window and SMTC overlap in time domain, then resource utilization is simplified, but the UE cannot simultaneously transmit data and perform measurement causing resource waste
Solution Approach 1:
The patent implements preliminary overlap detection mechanism that checks whether PUR search space window and SMTC measurement window overlap in time domain before operations begin. This early detection allows the system to proactively adjust configurations to avoid resource conflicts and waste
Solution Approach 2:
The system dynamically adjusts the PUR search space window timing based on detected overlap conditions. When overlap is detected, the window is shifted to a non-conflicting time slot, optimizing resource utilization by ensuring both measurement and data transmission functions can operate effectively without mutual interference

AI summary
A resource conflict processing method and device, a storage medium, a terminal, and a base station are provided. The method includes: determining whether a Preconfigure Uplink Resource (PUR) search space window and a SS block based RRM Measurement Timing Configuration (SMTC) overlap in time domain; and in response to the PUR search space window and the SMTC overlapping in time domain, transmitting uplink data to be transmitted through a PUR associated with the PUR search space window when there is uplink data to be transmitted; or, in response to the PUR search space window and the SMTC overlapping in time domain, performing a measurement in the SMTC according to a measurement requirement.
