Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If communication modes are switched dynamically to optimize energy usage, then energy consumption at base stations is reduced, but system complexity increases due to mode management overhead
Solution Approach 1:
The patent implements dynamic mode switching between full-duplex and half-duplex communication modes based on real-time channel conditions and traffic requirements. The base station dynamically adjusts the operational mode of bandwidth parts, allowing the system to adapt to changing conditions while optimizing energy consumption. This dynamic adjustment mechanism resolves the contradiction by making the system flexible rather than static.
Solution Approach 2:
The patent changes operational parameters (duplex mode, bandwidth part configuration) based on channel state information and traffic patterns. By monitoring channel quality indicators and adjusting communication parameters accordingly, the system can switch between energy-efficient modes and high-performance modes, thereby reducing overall energy consumption while maintaining necessary communication quality.
2Productivity
If full-duplex communication is used to enhance communication capacity, then data transmission efficiency is improved, but self-interference and energy consumption increase
Solution Approach 1:
The patent divides the communication spectrum into multiple bandwidth parts, where each bandwidth part can independently operate in full-duplex or half-duplex mode. This segmentation allows the system to apply full-duplex communication only to bandwidth parts where it is most beneficial, rather than forcing full-duplex operation across the entire spectrum, thereby reducing overall energy consumption while maintaining high communication capacity.
Solution Approach 2:
The patent applies full-duplex communication partially - only to specific bandwidth parts and time periods where it provides the most value. Rather than universally applying full-duplex mode, the system selectively enables it based on channel conditions and traffic requirements, achieving high productivity where needed while conserving energy in other scenarios.
3Use of energy by stationary object
If spatial elements are switched on/off to optimize energy usage, then energy efficiency is improved, but reliability may be compromised due to mode switching
Solution Approach 1:
The patent implements periodic mode switching based on time intervals and traffic patterns. By switching between spatial element configurations at regular intervals and based on periodic channel condition assessments, the system maintains reliable communication while optimizing energy usage. The periodic nature of the switching allows for predictable behavior and adequate transition times.
Solution Approach 2:
The patent uses channel state information and communication quality metrics as feedback to guide mode switching decisions. The system continuously monitors communication performance and adjusts spatial element configurations accordingly, ensuring that reliability requirements are met while achieving energy efficiency. The feedback mechanism prevents arbitrary switching that could compromise reliability.

AI summary
The present disclosure is to perform communication according to a mode related to energy saving in a wireless communication system, and a method performed by a terminal may comprise the steps of: receiving configuration information for configuring a transmission configuration indication (TCI)-related parameter; receiving control information including the TCI-related parameter; identifying a reference signal (RS) indicated by the TCI-related parameter; and transmitting or receiving a signal related to the control information on the basis of the RS. The configuration information may indicate, for one value of the TCI-related parameter, a first RS or a first radio resource applied to a first time interval, and a second RS or a second radio resource applied to a second time interval.
