Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio access node transmits synchronization signals using particular radio resources, then user equipment can maintain proper synchronization, but resources available for bearer data transmission are reduced
Solution Approach 1:
The patent implements dynamic toggling of synchronization signal transmission based on detected conditions. The radio access node switches between transmitting and not transmitting synchronization signals on particular radio resources according to system state, making the synchronization transmission dynamic rather than static to optimize resource allocation.
Solution Approach 2:
The patent changes the transmission parameter of synchronization signals by toggling them off under certain conditions. This parameter change (from transmitting to not transmitting) allows resources to be reallocated from overhead messaging to bearer data transmission while maintaining synchronization when needed.
2Ease of operation
If the radio access node transmits overhead messaging, then operating parameters are established, but resources available for bearer data transmission are reduced
Solution Approach 1:
The patent extracts synchronization signals from the particular radio resources under certain conditions, removing them from transmission to free up resources. This extraction allows the same radio resources to be used for bearer data transmission, thereby increasing throughput while operating parameters are established through other means.
Solution Approach 2:
The patent implements periodic or conditional transmission of synchronization signals rather than continuous transmission. By toggling synchronization signals based on detected conditions, the system performs synchronization messaging only when necessary, freeing resources for data transmission during other periods.
3Reliability
If synchronization signals are transmitted continuously, then user equipment maintains synchronization, but radio resources are wasted on unnecessary messaging
Solution Approach 1:
The patent makes synchronization signal transmission dynamic by toggling it based on detected conditions. Instead of continuous transmission, the system adaptively adjusts synchronization signal transmission to match actual system needs, reducing resource waste while maintaining synchronization reliability.
Solution Approach 2:
The patent uses condition detection as a feedback mechanism to control synchronization signal transmission. The system monitors system state and uses this feedback to decide when to transmit or suppress synchronization signals, ensuring synchronization is maintained only when necessary and resources are not wasted on unnecessary messaging.
Data Source
AI summary
System and methods for switching operating modes of a radio access node to increase data throughput for a user-equipment device are described. The radio access node can detect operating conditions to trigger switching from one operating mode to another. In a first operating mode, the radio access node can transmit non-bearer data, such as synchronization signals, to a UE device using a particular forward-link air interface resources. In response to detecting the defined condition(s), the radio access node can switch to a second operating mode in which the radio access node begins transmitting bearer data using the particular forward-link air interface resources used to transmit the non-bearer data while operating in the first operating mode. Upon detecting other operating condition(s), the radio access node can switch back to operating in the first operating mode. The radio access node can be configured as an eNodeB.
