Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If main radio is continuously activated to ensure communication availability, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The main radio dynamically switches between active and inactive states based on sensing results. When sensing detects user equipment or data transmission requirements, the main radio activates; when no activity is detected, it deactivates to save power, creating a dynamic adaptation to changing conditions
Solution Approach 2:
The system uses sensing information as feedback to control main radio activation. The sensing unit continuously monitors the environment and provides feedback signals that trigger main radio activation when user equipment is detected or data needs transmission, forming a closed-loop control system
2Loss of energy
If main radio is deactivated to reduce power consumption, then energy efficiency is improved, but communication responsiveness deteriorates
Solution Approach 1:
The sensing unit performs preliminary detection of user equipment and transmission requirements before activating the main radio. This advance detection ensures that when data needs to be transmitted, the main radio is already activated or can be quickly activated, minimizing response time
Solution Approach 2:
The system employs periodic sensing to monitor the environment for user equipment and transmission opportunities. This periodic detection creates regular intervals where the main radio can be activated based on sensed conditions, balancing power savings with responsive communication
3Adaptability or versatility
If sensing and communication operations are integrated, then system functionality is improved, but device complexity increases
Solution Approach 1:
The sensing unit and communication unit are merged into an integrated system where sensing information directly controls communication operations. The base station combines sensing results with communication scheduling to make unified decisions about resource allocation and main radio activation
Solution Approach 2:
The system implements multi-functionality where the same infrastructure supports both sensing operations and communication operations. The base station performs dual roles of sensing coordinator and communication manager, using a single system to achieve multiple objectives

AI summary
A 5th-generation (5G) or 6th-generation (6G) communication system for supporting higher data rates are provided. In addition, a method performed by a base station (BS) in a wireless communication system is provided. The method includes obtaining sensing information corresponding to a signal reflected from a sensing object, based on the sensing information, determining whether the sensing object is present in at least one cell, based on determining that the sensing object is present in the at least one cell, activating a main radio (MR) for the at least one cell, and based on determining that the sensing object is not present in the at least one cell, deactivating the MR for the at least one cell of the BS.
