WLAN/3GPP Aggregation Signaling for Cross-Release Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in optimizing signaling for efficient aggregation and interworking between 3GPP and WLAN networks, particularly due to unclear parameter usage across different 3GPP releases, leading to inefficiencies and potential instability in network operations.
Innovation Solution
A method and apparatus for optimizing signaling by indicating which parameters from a first standard (e.g., REL-12) are applicable to a second standard (e.g., REL-13) through mechanisms such as 1-bit indications, offsets, hysteresis, multipliers, and mode commands, allowing selective parameter utilization and simultaneous operation of REL-12 interworking and REL-13 aggregation.

Engineering Contradiction Analysis
1Adaptability or versatility
If parameters from REL-12 standard are applied to REL-13 aggregation without clear indication, then backward compatibility is maintained, but parameter confusion and operational instability occur
Solution Approach 1:
The patent segments parameter indication by introducing separate indication fields for REL-12 interworking parameters and REL-13 aggregation parameters. This allows the network to independently control and indicate which parameters from each release should be applied, eliminating confusion while maintaining both backward compatibility and forward compatibility.
Solution Approach 2:
The patent applies preliminary action by having the network pre-indicate which parameters are applicable before UE applies them. The network sends explicit indication information specifying which REL-12 and REL-13 parameters should be used, so the UE can correctly apply parameters in advance without ambiguity, preventing operational instability.
2Loss of information
If all parameters are indicated to UE, then complete information is provided, but signaling overhead increases
Solution Approach 1:
The patent extracts only the necessary parameter indications from the complete parameter sets. Instead of indicating all possible parameters, the network selectively indicates only those REL-12 and REL-13 parameters that are actually applicable and needed for the specific aggregation scenario, reducing signaling overhead while maintaining information completeness for the required parameters.
Solution Approach 2:
The patent applies partial action by providing indication information for only the subset of parameters that need to be controlled differently between REL-12 and REL-13. The indication mechanism allows the network to specify exactly which parameters require attention, avoiding the overhead of indicating all parameters when most can be inferred or have default behavior.
3Device complexity
If REL-12 and REL-13 operations are combined without distinction, then system simplicity is maintained, but parameter application errors occur
Solution Approach 1:
The patent applies local quality by introducing distinct indication fields and parameter structures for REL-12 and REL-13 parameters. Each parameter type has its own indication mechanism, allowing the UE to locally identify and apply the correct parameters with high precision. The separate indication information ensures that REL-12 interworking parameters and REL-13 aggregation parameters are clearly distinguished and applied to their respective functions without confusion.

AI summary
Various communication systems may benefit from the appropriate aggregation of multiple radio access technologies. For example, certain communication systems may benefit from optimized signaling for wireless local area network and third generation partnership projection aggregation. A method can include determining, by a network element, which parameters according to a first standard are also applicable according to a second standard for aggregation and/or interworking. The method can also include indicating the determined parameters to a user equipment.
