Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-configured cell groups are provided for terminal selection, then network management is simplified, but flexibility in dynamically determining cell configuration is limited
Solution Approach 1:
The configuration process is segmented into two independent parts: configuration information (defining candidate cells and their parameters) and indication information (activating specific cells from the candidate set). This segmentation allows the network to pre-configure multiple candidate cells while maintaining the flexibility to dynamically select and activate appropriate cells based on real-time conditions, thus resolving the contradiction between simplified management and dynamic flexibility.
Solution Approach 2:
The patent introduces dynamic cell activation by allowing the network device to send indication information that activates specific cells from the pre-configured candidate set. This dynamic mechanism enables the system to adapt to changing network conditions, user demands, and traffic patterns while maintaining the simplicity of pre-configuration, effectively balancing ease of operation with adaptability.
2Loss of information
If control signaling is used to configure cells, then configuration can be transmitted, but dynamic determination of cell activation states and types is not supported
Solution Approach 1:
The patent introduces an intermediary configuration information structure that defines a set of candidate cells with their parameters, which then serves as the basis for dynamic cell activation. This intermediary layer allows control signaling to efficiently transmit configuration data without requiring detailed dynamic reconfiguration, enabling both effective information transmission and flexible dynamic cell state determination through subsequent indication information.
3Adaptability or versatility
If multiple candidate cells are configured, then selection flexibility increases, but configuration complexity increases
Solution Approach 1:
The configuration information structure is designed to be universal and multi-functional, capable of defining multiple candidate cells with various parameters and types in a unified framework. This universal structure handles diverse cell configurations (different types, parameters, and activation states) through a single standardized mechanism, increasing selection flexibility while avoiding the need for multiple separate configuration structures, thus managing complexity effectively.

AI summary
A method for configuring a cell state, performed by a terminal, includes: receiving configuration information from a network device, and determining a candidate cell or a candidate cell group based on the configuration information; and receiving indication information from the network device, and determining at least one of an activation state and/or a type of the candidate cell, or at least one of an activation state and/or a type of the candidate cell group based on the indication information.
