Engineering Contradiction Analysis
1Productivity
If a reduced-capability UE performs both uplink transmission and downlink reception simultaneously, then communication efficiency is improved, but hardware complexity increases due to full-duplex requirements
Solution Approach 1:
The patent enables reduced-capability UEs to dynamically switch between half-duplex and full-duplex modes based on network configuration and service requirements. The UE can adapt its operation mode to balance between communication efficiency and hardware complexity, performing full-duplex operations only when necessary while defaulting to simpler half-duplex mode otherwise.
2Device complexity
If a reduced-capability UE uses half-duplex operation to reduce hardware complexity, then device complexity is reduced, but communication efficiency deteriorates due to inability to transmit and receive simultaneously
Solution Approach 1:
The patent designs the reduced-capability UE with multi-functional capability to support both half-duplex and full-duplex operations. The UE can universally operate in either mode depending on network configuration, making the device adaptable to different service requirements while maintaining reasonable hardware complexity by not permanently requiring full-duplex components.
3Productivity
If uplink transmission and downlink reception resources overlap in time, then resource utilization is improved, but signal interference increases
Solution Approach 1:
The patent segments the time-frequency resources into separate uplink and downlink portions, with a guard period inserted between them. This segmentation prevents overlap between uplink transmission and downlink reception resources, eliminating self-interference while still achieving high resource utilization through efficient time-division multiplexing.
Solution Approach 2:
The patent introduces a guard period as an intermediary time interval between uplink transmission and downlink reception. This guard period acts as a buffer that prevents direct interference between simultaneous operations, allowing the system to maintain high resource utilization while avoiding signal interference through proper temporal separation.
4Object-generated harmful factors
If a guard period is inserted between uplink and downlink to prevent interference, then signal interference is reduced, but time resource utilization deteriorates
Solution Approach 1:
The patent optimizes the guard period parameters (duration, positioning, frequency location) to minimize its impact on time resource utilization. By carefully adjusting these parameters, the system achieves adequate interference protection while maximizing the remaining time resources available for actual uplink and downlink transmissions.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data rate beyond a 4G communication system such as long term evolution (LTE). A method performed by a user equipment (UE) in a wireless communication system according to the disclosure includes receiving reduced-capability UE configuration information from a base station, receiving information for configuring uplink transmission and downlink reception from the base station, determining whether to perform the uplink transmission and the downlink reception, based on the reduced-capability UE configuration information, and performing at least one of the uplink transmission and the downlink reception, based on the determination.
