Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timing advance offset values are not properly managed in high frequency ranges, then communication performance deteriorates and interference increases, but implementing enhanced TA offset value indications adds system complexity
Solution Approach 1:
The patent applies parameter changes by introducing frequency-range-specific TA offset values (differentiating between FR1 and FR2 bands) and mode-specific offset values (full-duplex versus half-duplex). The base station configures different ta-OffsetValues for different frequency ranges and communication modes, allowing the system to adapt timing parameters to specific operational conditions without requiring complete system redesign.
Solution Approach 2:
The patent segments the timing advance offset configuration by dividing it into frequency-range-specific components (FR1 vs FR2) and communication-mode-specific components (full-duplex vs half-duplex). This segmentation allows independent optimization of TA offsets for different operational scenarios, managing complexity through modular parameter configuration rather than monolithic system changes.
2Productivity
If TA offset values are configured for different communication modes, then interference is reduced and communication efficiency improves, but the signaling overhead and configuration complexity increase
Solution Approach 1:
The patent implements universality by creating a multi-functional TA offset configuration system where a single set of RRC parameters (ta-OffsetValues) serves multiple purposes: it provides frequency-range-specific offsets and mode-specific offsets, and these offsets apply across different communication scenarios. This multi-functionality reduces the need for separate configuration mechanisms for each scenario.
Solution Approach 2:
The patent applies preliminary action by pre-configuring TA offset values through RRC signaling before actual communication occurs. The base station provides ta-OffsetValues in advance via RRCReconfiguration messages, allowing UEs to have TA offsets ready before entering specific communication modes or frequency ranges, thereby reducing real-time signaling overhead.
3Measurement precision
If default TA offset values are used without enhancement, then system simplicity is maintained, but timing alignment accuracy deteriorates leading to suboptimal performance
Solution Approach 1:
The patent applies local quality by providing specific TA offset values tailored to local conditions - different frequency ranges (FR1 vs FR2) and different communication modes (full-duplex vs half-duplex) each receive customized offset values. This local optimization ensures timing alignment accuracy is adapted to specific operational contexts rather than using universal defaults.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a timing advance (TA) offset value for a high frequency range operating band. The UE may communicate in the high frequency range operating band, in accordance with the TA offset value. In some aspects, a UE may receive an indication of at least one of a TA offset value associated with a full-duplex communication mode of a base station or a TA offset value associated with a half-duplex communication mode of a base station. The UE may communicate, with the base station, in accordance with at least one of the TA offset value associated with the full-duplex communication mode of the base station or the TA offset value associated with the half-duplex communication mode of the base station. Numerous other aspects are provided.
