Terminal Minimum Slot Offset Error Detection in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in next-generation radio access technologies like NR, there is a challenge in detecting errors related to the minimum slot offset, which can lead to misinterpretation of PS-PDCCH signals, resulting in reduced throughput due to fallback operations and increased power consumption.
Innovation Solution
A method is proposed where the terminal detects errors in the minimum slot offset detection and performs a fallback operation, allowing it to adjust its processing and buffering strategies based on preconfigured minimum slot offset values, ensuring optimal resource allocation and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal performs strict detection of minimum slot offset to ensure accuracy, then measurement precision is improved, but false alarm rate increases causing unnecessary fallback operations and reduced throughput
Solution Approach 1:
The terminal uses feedback from the PS-PDCCH to dynamically adjust its detection threshold and operation mode. When power saving signal is detected, the terminal modifies its minimum slot offset detection parameters to balance between detection accuracy and avoiding false alarms, thereby maintaining throughput while ensuring reliable power saving operation.
Solution Approach 2:
The terminal changes detection parameters such as threshold values and monitoring intervals based on the detected power saving signal state. By adapting these parameters dynamically, the system achieves both accurate minimum slot offset detection and high throughput, resolving the contradiction between precision and productivity.
2Use of energy by moving object
If the terminal performs frequent power saving operations to reduce power consumption, then energy efficiency is improved, but detection reliability decreases due to increased false alarms
Solution Approach 1:
The terminal dynamically adjusts its power saving operation intensity based on real-time detection conditions. The system transitions between different operational modes (e.g., aggressive power saving vs. conservative detection) to maintain reliable detection while minimizing power consumption, preventing false alarms from compromising reliability.
Solution Approach 2:
Feedback mechanisms allow the terminal to learn from previous detection outcomes and adjust its power saving strategy accordingly. By monitoring detection results and false alarm rates, the system optimizes its power saving operations to maintain high reliability while reducing energy consumption.
3Use of energy by moving object
If the terminal uses aggressive power saving strategies to reduce power consumption, then energy efficiency is improved, but throughput decreases due to excessive fallback operations
Solution Approach 1:
The terminal changes operational parameters such as detection thresholds, monitoring frequencies, and fallback triggers based on the balance between power saving needs and throughput requirements. This adaptive parameter adjustment allows the system to achieve both low power consumption and high throughput by preventing excessive fallback operations.
Solution Approach 2:
The power saving strategy is made dynamic, allowing the terminal to adjust its aggressiveness level based on current system conditions. When detection reliability is high, the terminal can use more aggressive power saving; when false alarms increase, the system automatically reduces power saving intensity to maintain throughput.

AI summary
The present specification provides an error detection method performed by a terminal in a wireless communication system, the method comprising: determining whether a minimum slot offset from a base station has been detected, wherein the minimum slot offset is a slot offset associated with an expectation that the terminal should receive a physical downlink shared channel (PDSCH) on the basis of at least one slot offset having a value equal to or greater than that of the minimum slot offset; detecting an error relating to detection of the minimum slot offset; and performing a fallback operation on the basis of the error detection.
