UE Uplink Gap Calibration Signaling for Network-Aware Transmission Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems face challenges in configuring uplink gaps (UL gaps) for self-calibration and monitoring within user equipment (UE) due to network inability to respond to UL gap configuration requests, leading to inefficiencies and potential interference, especially when the network does not support UL gap configuration.
Innovation Solution
Implementing a terminal with a receiving unit for configuration information, a transmitting unit for terminal capability signaling, and a control unit to perform self-calibration and monitoring based on network support and specific transmission conditions, ensuring efficient UL gap configuration and minimizing interference.

1Reliability
If the UE requests scheduling for configuring the UL gap, then the UE can perform calibration inside the UE, but the network may be unable to respond to it when the network does not support configuration of the UL gap
Solution Approach 1:
The UE transmits terminal capability information indicating UL gap calibration capability in advance, before the network responds to the scheduling request. This preliminary action ensures the network is aware of the UE's capability and can make informed decisions about configuration, preventing situations where the network cannot respond appropriately.
Solution Approach 2:
The network receives the terminal capability information and provides feedback by either configuring the UL gap or indicating non-support. This feedback mechanism ensures bidirectional communication about capability support, allowing the system to adapt to network capabilities while maintaining UE calibration needs.
2Use of energy by moving object
If the UL gap is configured for calibration, then power efficiency of the UE is improved, but transmission efficiency may be reduced due to stopping transmission
Solution Approach 1:
The UL gap is configured as a periodic time domain resource where transmission is stopped only during specific intervals for calibration, while transmission continues during other periods. This periodic approach allows the UE to perform calibration regularly to improve power efficiency while maintaining overall transmission productivity through continuous operation during non-gap periods.

AI summary
A terminal includes a receiving unit that receives configuration information for configuring a time and frequency domain in which a transmission is stopped; a transmitting unit that transmits terminal capability information indicating that the terminal is capable of performing calibration by stopping the transmission in the time and frequency domain; and a control unit that performs the calibration by stopping the transmission in the time and frequency domain based on the configuration in a case where the receiving unit receives the configuration information and the transmitting unit transmits the terminal capability information.
