Solution Overview
Problem
Current wireless communication systems face challenges in enabling simultaneous transmission and reception capabilities across multiple antenna panels, particularly in multi-TRP scenarios, which affect mobility, reliability, and spectrum efficiency.
Innovation Solution
The implementation of a wireless transmit/receive unit (WTRU) with multiple antenna panels capable of operating in simultaneous downlink/downlink (S-DD), simultaneous uplink/uplink (S-UU), and simultaneous downlink/uplink (S-DU) modes, using transmission control indicators and reference signals for efficient communication with multiple transmission and reception points.

Engineering Contradiction Analysis
1Productivity
If a WTRU uses multiple antenna panels for simultaneous transmission and reception, then spectrum efficiency and reliability are improved, but device complexity and interference management difficulty increase
Solution Approach 1:
The WTRU divides its antenna system into multiple independent antenna panels, where each panel can operate independently in different modes (transmission or reception). This segmentation allows simultaneous DL/UL operations on different panels without requiring the entire system to switch modes, thereby improving spectrum efficiency while managing complexity through modular organization
Solution Approach 2:
The system dynamically configures each antenna panel's operation mode based on current communication needs. The WTRU can flexibly switch individual panels between transmission and reception modes, and adjust beam directions and resource allocations in real-time, enabling adaptive optimization of spectrum efficiency while maintaining manageable system complexity
2Reliability
If a WTRU communicates with multiple TRPs simultaneously, then reliability and mobility are enhanced, but the difficulty of beam management and signal coordination increases
Solution Approach 1:
The patent introduces reference signals as intermediary elements that facilitate communication between the WTRU and multiple TRPs. These reference signals serve as measurement benchmarks that simplify beam management by providing standardized targets for beam alignment, quality assessment, and coordination across multiple transmission points, thereby reducing the difficulty of managing simultaneous communications
Solution Approach 2:
The system implements feedback mechanisms where the WTRU measures reference signals from multiple TRPs and reports channel state information back to the network. This feedback loop enables dynamic beam adjustment and coordination, allowing the system to maintain reliable simultaneous communications with multiple TRPs while automatically adapting to changing channel conditions and reducing beam management complexity

AI summary
System(s), method(s), and device(s) for simultaneous transmission and reception is disclosed here. A wireless transmit receive unit (WTRU) may have multiple antenna panels which may be capable of different modes of operation, such as simultaneous DL/DL (S-DD), simultaneous UL/UL (S-UU) and simultaneous DL/UL (S-DU). Further, the WTRU may use each panel independently to communicate with multiple transmission and receive points simultaneously. The WTRU may accomplish this using transmission control indicators, reference signals, monitoring techniques suitable for multiple transmission and reception point communication.
