Symbol Duplex Indication for Dynamic UL/DL Transmission Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in transmission direction indication, particularly in duplexing enhancement, which affects the performance of user equipment in managing uplink and downlink transmissions.
Innovation Solution
A method for user equipment in a wireless communication system that receives indications of applicable symbol duplex enhancement, allowing for uplink transmission on applicable downlink symbols and canceling uplink transmission on non-applicable symbols, enhancing duplexing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional transmission direction indication is used, then system compatibility is maintained, but indication efficiency is insufficient for duplexing enhancement
Solution Approach 1:
The patent implements dynamic transmission direction indication by enabling user equipment to perform both uplink and downlink operations on the same symbol when duplex enhancement is applicable, rather than using static time-division duplexing. This dynamic approach allows the system to adapt transmission directions in real-time based on duplex enhancement indications, improving indication efficiency while managing complexity through standardized procedures.
2Productivity
If symbol duplex enhancement is applied, then uplink transmission opportunities increase, but transmission direction management becomes more complex
Solution Approach 1:
The patent employs feedback mechanisms where the network provides duplex enhancement indications to user equipment, enabling them to determine whether to perform uplink or downlink operations on specific symbols. This feedback loop allows the system to optimize uplink transmission opportunities while maintaining manageable operation through clear indication protocols and standardized decision-making procedures at the user equipment.

AI summary
Methods, systems, and apparatuses are provided for transmission direction indication in a wireless communication system to improve indication efficiency in transmission direction for duplexing enhancement. A User Equipment (UE) in a wireless communication system comprises receiving indication(s) of which symbol duplex enhancement is applicable, performing UL transmission on a first Downlink (DL) symbol if/when duplex enhancement is applicable for the first DL symbol, and canceling Uplink (UL) transmission on a second DL symbol if/when duplex enhancement is not applicable for the second DL symbol.
