User Equipment Reference Signal Transmission Priority Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, user equipment in dynamic TDD environments face interference issues due to simultaneous transmission and reception of reference signals and other signals, leading to potential signal degradation or failure in measuring interference effectively.
Innovation Solution
The user equipment is equipped with a configuration information management unit to manage priority levels for transmitting and receiving reference signals, determining whether to transmit or receive based on predetermined priority levels to avoid contention with other signals, ensuring accurate interference measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment transmits and receives reference signals simultaneously with other signals, then signal communication functionality is maintained, but interference measurement precision deteriorates due to signal contention
Solution Approach 1:
The patent implements dynamic priority-based signal transmission control where the user equipment adjusts reference signal transmission based on real-time signal contention conditions. When contention is detected, the system dynamically determines whether to transmit the reference signal based on predetermined priority levels, allowing flexible adaptation between maintaining communication functionality and ensuring measurement precision
Solution Approach 2:
The system changes the transmission parameter (reference signal transmission state) based on the priority level parameter. By comparing priority levels of different signals, the system determines whether to transmit or drop the reference signal, thus resolving the contradiction between maintaining signal communication and ensuring measurement precision
2Measurement precision
If user equipment prioritizes reference signal transmission to ensure interference measurement precision, then measurement precision is improved, but other signal communication may be affected
Solution Approach 1:
The system uses priority level parameters to control reference signal transmission. By comparing the priority level of the reference signal with other signals, the system dynamically adjusts transmission behavior, ensuring that reference signals are transmitted only when they have higher priority, thus balancing measurement precision with communication reliability
Solution Approach 2:
The system implements a feedback mechanism where the user equipment continuously monitors signal contention conditions and adjusts reference signal transmission accordingly. The predetermined priority levels serve as feedback criteria to determine whether transmission should occur, ensuring that measurement precision is maintained without compromising other signal communications

AI summary
A user equipment in a wireless communication system includes a configuration information management unit configured to retain configuration information for transmitting a reference signal used for measuring interference in other user equipments, and a signal transmitter configured to transmit the reference signal based on the configuration information. When transmission of the reference signal contends with transmission or reception of another signal, the signal transmitter determines whether the reference signal is to be transmitted or not based on a predetermined priority level.
