Engineering Contradiction Analysis
1Reliability
If a wireless communication device transmits a sensing signal in an irregular slot using normal transmit power, then the sensing signal can be transmitted with sufficient power for reliable detection, but the throughput and quality of service of other communication devices will be degraded due to increased interference
Solution Approach 1:
The patent applies parameter changes by modifying the transmit power level specifically for sensing signals in irregular slots. The network node configures a first transmit power level for sensing signals in irregular slots, which is different from the normal transmit power used in regular slots. This power adjustment allows the sensing signal to be transmitted with sufficient power for reliable detection while minimizing interference to other communication devices, thereby resolving the contradiction between detection reliability and system throughput.
Solution Approach 2:
The patent implements local quality by applying different transmit power characteristics to different types of transmissions. Specifically, sensing signals in irregular slots use a first transmit power level, while other communication devices use normal transmit power levels. This localized power adjustment ensures that only the sensing signals in irregular slots are affected by the power constraint, allowing reliable sensing while maintaining the throughput of other communications.
2Productivity
If a wireless communication device transmits a sensing signal in an irregular slot using reduced transmit power, then the interference to other communication devices is minimized, but the sensing signal may not achieve sufficient detection range or reliability
Solution Approach 1:
The patent resolves this contradiction by implementing parameter changes through network node configuration. The network node is configured to transmit sensing signals in irregular slots using a first transmit power level that is optimized for this specific scenario. This configured power level represents a parameter change from normal transmission power, allowing the system to achieve both reduced interference to other devices and sufficient detection reliability for sensing signals.
3Productivity
If a wireless communication device uses beam parameter configuration for sensing signals in irregular slots, then the directionality is improved to reduce interference, but the device complexity increases due to additional configuration requirements
Solution Approach 1:
The patent applies universality by using the existing beamforming framework for multiple purposes. The network node uses the same beam configuration mechanisms that are already employed for normal communications to also handle sensing signals in irregular slots. This multi-functional approach allows the system to improve directionality and reduce interference for sensing signals while avoiding the need for entirely new configuration systems, thereby limiting the increase in device complexity.

AI summary
An irregular slot may include a scenario in which a user equipment (UE) transmits a sensing signal, which may be an uplink transmission, in a downlink slot or a flexible slot. In some other examples, an irregular slot may include a scenario in which a transmit receive point (TRP) transmits a sensing signal, which may be a downlink transmission, in an uplink slot or a flexible slot. As a result, the sensing signal transmission can degrade throughput and/or quality of service of other communication devices' transmissions. Accordingly, a wireless communication device, such as a UE or a TRP, that is to transmit a sensing signal in an irregular slot may be configured with a power constraint parameter or a beam parameter. In some examples, aspects of the present disclosure may reduce an impact of interference or noise on other wireless communication devices' transmissions.
