Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If static transmission of glue reference signals is used to maintain phase continuity across phase jump boundaries, then phase measurement accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent transforms the static transmission approach into a dynamic one by introducing triggering mechanisms. The network device determines whether phase jump boundaries exist and only transmits glue reference signals when necessary. This dynamic adaptation allows the system to maintain phase measurement accuracy when phase jumps occur while avoiding unnecessary signal transmissions when they don't, thereby resolving the contradiction between measurement precision and signaling overhead.
Solution Approach 2:
The patent changes the transmission parameter from always-present to conditionally-present based on the presence of phase jump boundaries. By making the transmission of glue reference signals conditional rather than static, the system optimizes the balance between maintaining phase continuity for accurate measurements and reducing overhead by eliminating redundant transmissions.
2Reliability
If glue reference signals are transmitted in all symbols to ensure phase continuity, then reliability of phase measurements is improved, but resource efficiency deteriorates
Solution Approach 1:
The patent implements dynamic transmission where the network device determines the presence of phase jump boundaries and only transmits glue reference signals in symbols where such boundaries exist. This dynamic approach ensures reliable phase measurements when needed while improving resource efficiency by avoiding transmissions in symbols without phase jumps, thus resolving the contradiction between reliability and productivity.
Solution Approach 2:
The patent extracts only the necessary glue reference signal transmissions from the set of all possible transmissions. By identifying and removing redundant transmissions in symbols without phase jump boundaries, the system maintains measurement reliability where required while eliminating waste, thereby improving overall resource efficiency.
3Quantity of substance
If phase jump boundaries are detected and handled dynamically, then overhead is reduced, but system complexity increases
Solution Approach 1:
The patent enables the system to self-determine the presence of phase jump boundaries through the triggering mechanism. The network device autonomously detects phase jump boundaries and decides whether to transmit glue reference signals without requiring complex external coordination, thus reducing overhead while managing complexity through self-service operation.
Solution Approach 2:
The patent incorporates feedback mechanisms where the determination of phase jump boundaries informs the transmission decisions. This feedback loop allows the system to adapt transmissions based on actual conditions, reducing overhead by avoiding unnecessary signals while managing complexity through structured feedback processing rather than uncontrolled complexity.

AI summary
Methods, systems, and devices for wireless communications are described. A first wireless device and a second wireless device may coordinate the presence of a reference signal in one or more symbols of a slot, where the reference signal is associated with phase measurements across a phase jump boundary of the slot. In some aspects, the first wireless device may receive control information that triggers the transmission of the reference signal in the one or more symbols of the slot, where the control information may further indicate the position of the one or more symbols within the slot. In such aspects, the one or more symbols associated with the reference signal may be prior to the phase jump boundary, after the phase jump boundary, or a combination of both. As such, the first wireless device may monitor the one or more symbols, receive the reference signal, and perform the phase measurements.
