Temporary Reference Signal Burst Interval Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly during the dynamic spectrum sharing (DSS) project of 3GPP Release 17, the secondary cell (SCell) activation/de-activation process is hindered by conflicts in transmission resources for temporary reference signals (RS), leading to inefficiencies in Automatic Gain Control (AGC) adjustment and Time/Frequency tracking.
Innovation Solution
A method is introduced to determine the transmission resource and time interval for temporary RS bursts, even when resources conflict, by using network-side configuration and predefined rules or base station indications, ensuring adequate time for AGC setting and T/F tracking through Downlink Control Information (DCI) or Media Access Control (MAC) Control Elements (CE).

1Productivity
If temporary RS bursts are transmitted adjacently without time interval, then transmission efficiency is improved, but transmission quality deteriorates due to resource conflicts
Solution Approach 1:
The patent applies dynamics by making the time interval between temporary RS bursts configurable and adaptive. The network can dynamically adjust the time interval parameter based on system conditions, allowing the system to optimize between transmission efficiency and quality. When resources conflict, a larger time interval is applied; when resources are available, a smaller or zero interval can be used.
Solution Approach 2:
The patent changes the parameter of time interval between temporary RS bursts from a fixed value to a configurable parameter. By modifying this parameter, the system can resolve resource conflicts while maintaining transmission efficiency. The network side can indicate different time interval values through DCI or MAC CE to adapt to different transmission scenarios.
2Reliability
If time interval is increased between temporary RS bursts, then transmission quality is improved, but activation speed deteriorates
Solution Approach 1:
The time interval between temporary RS bursts is made dynamic rather than fixed. The network can adjust the interval length based on whether resource conflicts exist, allowing the system to minimize time loss during normal operation while ensuring sufficient interval only when necessary for transmission quality.
Solution Approach 2:
The patent introduces parameter configurability for the time interval, allowing it to be changed based on system conditions. This enables the network to optimize the balance between transmission quality and activation speed by selecting appropriate interval values for different scenarios.

AI summary
A method for processing a temporary reference signal (RS) burst. The method includes: determining, based on a network side configuration, a transmission resource of one of two temporary RS bursts; and determining a time interval between two temporary RS bursts transmitted adjacently in a case that the transmission resource conflicts with a resource unavailable for transmitting any temporary RS burst.
