Temporary Reference Signal Resource Conflict Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, temporary reference signals (TRS) face transmission failures due to resource conflicts, leading to poor reliability, especially when they overlap with uplink symbols, reserved resources, or cell-specific reference signals, which hinders automatic gain control (AGC) and time-frequency domain tracking.
Innovation Solution
A method is introduced where a terminal determines a transmission resource for a third temporary reference signal (TRS) based on a resource conflict result, shifting the first TRS burst if a conflict occurs, to avoid unavailable resources, ensuring no overlap and improving transmission reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a temporary reference signal is transmitted on a determined transmission resource, then the activation process of the secondary cell is accelerated, but resource conflicts with uplink symbols or reserved resources cause transmission failures
Solution Approach 1:
The patent applies preliminary action by determining resource conflicts before transmitting the temporary reference signal. The base station checks whether the determined transmission resource conflicts with uplink symbols or reserved resources in advance, and if a conflict is detected, it adjusts the transmission resource before sending the signal, thereby preventing transmission failures and improving reliability.
2Reliability
If the transmission resource is adjusted to avoid conflicts, then transmission reliability is improved, but the resource allocation becomes more complex
Solution Approach 1:
The patent implements feedback by having the terminal feed back information about resource conflicts to the base station. The base station uses this feedback to intelligently adjust the transmission resource of the temporary reference signal, avoiding conflicts with uplink symbols or reserved resources while maintaining efficient resource allocation through informed decision-making.

AI summary
A method, communication device, and computer readable medium for improving the reliability of a wireless communication network. The reliability is improved by: according to a resource conflict result, determining a transmission resource configured to receive a third temporary reference signal (RS) according to a resource conflict result, where the resource conflict result includes a result that a conflict or no conflict occurs between a transmission resource determined based on a first temporary RS burst and an unavailable resource.
