Engineering Contradiction Analysis
1Productivity
If full duplex (FD) communication is enabled to increase spectral efficiency, then spectral efficiency is improved, but self-interference and harmful factors increase in environments with blockages and interference
Solution Approach 1:
The system dynamically switches between full duplex and half duplex operating modes based on geographic location and interference conditions. The base station determines a default operating mode for each zone and UEs can adjust their operating mode based on measurements and network signaling, allowing the system to adapt to changing environmental conditions and minimize self-interference while maintaining spectral efficiency when conditions permit
Solution Approach 2:
Different operating modes are assigned to different geographic zones based on local interference conditions. The base station broadcasts default operating mode information for specific zones, and UEs select appropriate modes based on their location and measured interference levels, allowing optimal performance in each local environment rather than using a uniform mode system-wide
2Productivity
If full duplex (FD) communication is enabled to increase spectral efficiency, then spectral efficiency is improved, but communication reliability deteriorates in environments with numerous blockages and interference
Solution Approach 1:
The system dynamically adjusts the operating mode based on real-time measurements of interference and blockage conditions. UEs perform measurements and compare against thresholds to determine whether to operate in FD or HD mode, allowing the system to maintain reliability by switching to HD mode when conditions are unfavorable while maximizing spectral efficiency when conditions permit
Solution Approach 2:
The system uses feedback from interference measurements and QoS evaluations to determine the appropriate operating mode. UEs measure interference levels, compare them to thresholds, and select operating modes accordingly. Network entities also provide feedback through signaling about default operating modes for specific zones, creating a closed-loop system that adapts to maintain both efficiency and reliability
3Productivity
If dynamic operating mode selection is implemented based on location and interference measurements, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
UEs autonomously determine their operating mode by performing interference measurements, comparing results to thresholds, and selecting the appropriate mode without requiring complex network control. The UE independently evaluates conditions and makes mode selection decisions, reducing the complexity burden on the network while maintaining efficient operation
Solution Approach 2:
The system changes operating parameters (operating mode, communication parameters) based on measured conditions and zone information. The base station broadcasts default operating mode information for zones, and UEs adjust their parameters based on location and interference measurements, allowing efficient adaptation through parameter adjustment rather than complex system reconfiguration

AI summary
Methods, systems, and devices for wireless communications are described. A base station may determine a default operating mode based on the geographic location (e.g., zone) of the base station, for user equipment (UEs) operating in that zone to use. The operating mode may be a full duplex (FD) operating mode or a half duplex (HD) operating mode. A UE operating in the zone may receive, from the base station, an indication of the default operating mode corresponding to the zone, and may select an operating mode based on the indication. The mode selected by the UE may be the same as or different than the indicated default operating mode. For example, the UE may determine to use either FD mode or HD mode based on operation parameters, interference measurements, signaling from a base station or other UEs, one or more measurement thresholds, or some combination thereof.
