Solution Overview
Problem
Current wireless communication systems, particularly in the context of 5G, face challenges in effectively managing radar signals and their interference with uplink transmissions, leading to inefficiencies in spectral usage and increased latency due to the lack of optimized power control mechanisms for radar signals in mmW RF environments.
Innovation Solution
A method is introduced to determine and configure power control parameters for radar signals, including maximum interference levels and transmission power adjustments, to mitigate interference between radar signals and uplink transmissions, utilizing a radar controller that manages time-frequency resources and transmits requests for measurement operations to base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radar signals are transmitted in mmW RF environment, then radar functionality is achieved, but interference with uplink transmissions increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting power control parameters for radar signals based on uplink transmission conditions. The network device determines adjusted power control parameters when uplink transmissions are detected, modifying transmission power levels to reduce interference while maintaining radar functionality. This resolves the contradiction by changing the power parameter of radar signals adaptively.
Solution Approach 2:
The patent implements dynamics through dynamic power control where the radar signal transmission power is not fixed but adjusted in real-time based on uplink transmission detection. The network device continuously monitors and modifies power control parameters, making the radar transmission adaptive to current communication conditions, thus reducing interference dynamically.
2Productivity
If power control parameters are adjusted to reduce interference, then spectral efficiency improves, but system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the network device to autonomously determine and adjust power control parameters without requiring complex external coordination. The network device itself performs the detection of uplink transmissions and calculates the appropriate power adjustments, simplifying the overall system architecture while improving spectral efficiency through intelligent self-management.
Solution Approach 2:
The patent implements feedback mechanisms where the network device monitors uplink transmission conditions and uses this information to adjust radar power control parameters. This closed-loop feedback approach allows the system to automatically optimize spectral efficiency based on real-time conditions without requiring complex manual intervention or external control systems.

AI summary
In an aspect, a first base station (e.g., Rx gNB) receives, from a radar controller, a configuration of UL T-F resources for the first base station to receive at least one radar signal from a second base station. The first base station further determines power control parameter(s) associated with the at least one radar signal, at least one UL transmission, or a combination thereof. The first base station performs, based on the power control parameter(s), action(s) to mitigate impact by the at least one radar signal to the at least one UL transmission, or by the at least one UL transmission to the at least one radar signal, or a combination thereof. The first base station measures the at least one radar signal on the set of UL T-F resources in accordance with the configuration.
