Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronization signals and broadcast channel signals are continuously transmitted, then communication reliability is maintained, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic on/off control of synchronization signals and broadcast channel signals based on actual network conditions and user equipment states. The base station can adaptively adjust signal transmission status rather than maintaining continuous transmission, thereby improving resource allocation efficiency while maintaining communication reliability when needed.
Solution Approach 2:
The patent changes the transmission parameter (on/off state) of synchronization signals and broadcast channel signals dynamically. By adjusting the transmission status parameter based on network conditions, the system achieves better resource utilization without compromising essential communication functions.
2Productivity
If synchronization signals and broadcast channel signals are turned off to save resources, then resource allocation efficiency improves, but communication procedure reliability deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms where the base station monitors network conditions, user equipment states, and signal reception quality. Based on this feedback, the system makes informed decisions about turning synchronization signals and broadcast channel signals on or off, ensuring that reliability is maintained when signals are turned off and resources are saved when conditions permit.
Solution Approach 2:
The patent performs preliminary assessments of network conditions and user equipment states before turning off synchronization signals and broadcast channel signals. This preliminary action ensures that turning off signals will not compromise communication procedure reliability, as the system verifies conditions are appropriate beforehand.
3Productivity
If dynamic on/off control of SSB is implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the control of synchronization signals and broadcast channel signals into independent on/off states for different signal types and different time periods. This segmentation allows for manageable complexity by controlling individual signals rather than the entire system simultaneously, making the dynamic control mechanism more tractable.
4Loss of energy
If SSB transmission is dynamically adjusted, then energy consumption is reduced, but signal detection capability deteriorates
Solution Approach 1:
The patent implements periodic transmission of synchronization signals and broadcast channel signals rather than continuous transmission. By transmitting signals periodically at optimized intervals, the system reduces energy consumption while maintaining sufficient signal detection capability for user equipment to synchronize and access the network effectively.

AI summary
The present disclosure relates to turning on/off a synchronization signal and a broadcast channel signal in a wireless communication system. This operating method of a terminal may comprise the steps of: receiving downlink control information (DCI) related to system information; acquiring allocation information for receiving the system information on the basis of the DCI; receiving the system information on the basis of the allocation information; acquiring first information related to the position of synchronization signal/physical broadcast channel blocks (SSBs) included in the system information; receiving second information related to on or off of the SSBs; and receiving at least one of the SSBs on the basis of the first information and the second information.
