Flexible Allocation Slots for Partially Overlapping Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 3GPP New Radio (NR), measurement gaps partially overlap with communication slots, leading to inefficiencies as existing technologies discard operational tasks in partially overlapped slots, resulting in lost scheduling opportunities and reduced throughput.
Innovation Solution
A method and system that determine and utilize non-overlapped portions of communication slots for scheduled operational tasks by adjusting time domain resource allocations and reference signals, allowing for continued PDCCH monitoring, PDSCH reception, CSI-RS measurement, PUSCH transmission, and SRS transmission even in slots partially overlapped by measurement gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement gaps are configured for UE to perform measurements on other cells, then measurement capability is improved, but scheduling opportunities are lost in partially overlapped slots
Solution Approach 1:
The patent segments the communication slot into two distinct portions: a first portion that does not overlap with the measurement gap and a second portion that overlaps with the measurement gap. This segmentation allows the UE to perform scheduled operational tasks in the non-overlapped first portion while maintaining measurement capability during the measurement gap period, thereby resolving the contradiction between measurement reliability and scheduling productivity.
2Reliability
If existing technologies discard operational tasks in partially overlapped slots, then measurement gap functionality is maintained, but throughput is reduced
Solution Approach 1:
The patent applies partial action by enabling the UE to perform scheduled operational tasks only in the non-overlapped first portion of the slot rather than discarding all tasks in partially overlapped slots. This partial utilization approach maintains measurement gap functionality while maximizing throughput by utilizing available time resources efficiently.
3Productivity
If time domain resource allocations are adjusted to utilize non-overlapped portions, then scheduling opportunities are increased, but allocation complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the treatment of different slot portions: the first non-overlapped portion is designated for scheduled operational tasks while the second overlapped portion is designated for measurement activities. This localized differentiation allows flexible time domain resource allocation without requiring complex system-wide changes, thereby increasing scheduling opportunities while managing allocation complexity.
