Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous communication transmission is maintained to ensure coverage and reliability, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic communication activation and deactivation cycles. The base station receives indication information from the UE at specific intervals (periodic reporting), and communications are activated only when needed (when UE has data to transmit or network needs to send data). This periodic operation pattern allows the system to maintain reliability by checking in regularly while saving energy by remaining inactive between periods.
Solution Approach 2:
The UE autonomously determines when to activate communications based on its own data buffer status and transmission needs. The UE sends indication information to the base station when it has data to transmit, and the base station autonomously activates the cell for communication. This self-service mechanism eliminates the need for continuous network-controlled activation, reducing energy consumption while maintaining communication reliability.
2Speed
If communication resources are continuously allocated to support high data rates, then data transmission speed is improved, but network resource efficiency deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where communication resources are allocated based on real-time network conditions and UE requirements. The base station receives indication information from the UE and dynamically activates communication resources only when high data rate transmission is actually needed. This dynamic approach allows the system to provide high-speed transmission when required while efficiently releasing resources for other uses when not needed, thereby improving overall network resource efficiency.
3Measurement precision
If the base station continuously monitors all cells for UE presence, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts the monitoring function from continuous operation and implements it only when necessary. Instead of continuously monitoring all cells, the base station monitors specific cells based on indication information received from UEs. The monitoring is extracted and activated only for cells where UEs have indicated they may need to communicate, thereby maintaining detection accuracy while significantly reducing system complexity by eliminating unnecessary monitoring of inactive cells.

AI summary
Apparatuses and methods for activating or deactivating communications on a cell. A method for a user equipment (UE) includes receiving first information indicating reception occasions for a first signal or a first channel, receiving second information indicating time resources or frequency resources for transmission of a second signal or a second channel, and receiving the first signal or the first channel. The method further includes determining to transmit the second signal or the second channel based on the reception of the first signal or channel and transmitting the second signal or the second channel.
