Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transmission parts are statically assigned to user equipment, then configuration simplicity is maintained, but beam and waveform blocking and interference occur in heterogeneous networks
Solution Approach 1:
The patent implements dynamic TP hopping where UEs switch between different TPs according to a configured hopping pattern. Instead of static TP assignment, the system dynamically changes the active TP over time based on the hopping pattern, which improves reliability by avoiding persistent beam blocking and interference while managing complexity through standardized hopping patterns.
Solution Approach 2:
The patent employs periodic TP hopping where UEs transition between TPs in regular intervals defined by the hopping pattern. This periodic switching prevents continuous exposure to blocked beams or interfering waveforms by systematically changing the active TP over time, thereby improving communication reliability without requiring complex adaptive algorithms.
2Reliability
If TP hopping is implemented to avoid blocking and interference, then communication reliability improves, but signaling overhead and delays increase
Solution Approach 1:
The patent configures TP hopping patterns in advance through RRC signaling, where the hopping pattern (including sequence of TPs and timing) is predetermined and communicated to the UE before actual hopping occurs. This preliminary configuration allows the UE to autonomously execute the hopping pattern without real-time signaling for each TP switch, thereby improving reliability through systematic TP diversity while minimizing signaling delays.
3Adaptability or versatility
If TP hopping configuration is provided to all UEs, then adaptability to diverse UE capabilities is achieved, but signaling overhead increases
Solution Approach 1:
The patent provides individualized TP hopping configurations to each UE based on its specific capabilities and requirements. The base station determines and configures distinct hopping patterns for different UEs, allowing each UE to benefit from TP hopping adapted to its capabilities while avoiding the need to broadcast comprehensive hopping configurations to all UEs uniformly, thus achieving adaptability without excessive signaling overhead.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a transmission part (TP) hopping configuration that indicates one or more TPs and a TP hopping pattern associated with one or more hops between the one or more TPs. The UE may communicate, with the base station, using a TP of the one or more TPs based at least in part on the TP hopping configuration. Numerous other aspects are described.
