Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reference signals are transmitted and received within a threshold time in 6G networks, then communication reliability and data rate are improved, but system complexity and timing synchronization requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring channel occupancy time (COT) information and threshold time parameters before reference signal transmission. The first device determines the COT and communicates it to the second device in advance, allowing the second device to prepare for timely reception and response within the threshold time window, thereby ensuring communication reliability without requiring complex real-time synchronization mechanisms
Solution Approach 2:
The patent uses channel occupancy time (COT) information as an intermediary element that mediates the timing relationship between reference signal transmission and reception. By introducing COT as a intermediate parameter that both devices can reference, the system achieves synchronized communication within threshold time without requiring direct complex timing coordination between devices
2Reliability
If channel occupancy time is extended to accommodate reference signal exchange, then communication completeness is improved, but channel availability for other transmissions decreases
Solution Approach 1:
The patent applies dynamics by making the channel occupancy time (COT) configurable and adaptable. The first device can determine and adjust the COT length based on communication needs, allowing the system to dynamically allocate channel resources. This enables the channel to be occupied for sufficient time to complete reference signal exchange when needed, while releasing it quickly back to the pool of available channels to maximize overall channel availability and utilization efficiency

AI summary
Provided are a method for a first device to perform wireless communication and a device for supporting same. The first device may: transmit information related to channel occupancy time (COT) to a second device; transmit a first reference signal to the second device; and receive a second reference signal from the second device within a threshold time. Here, the COT may be generated by the first device to be equal to or longer than the threshold time.
