Carrier Aggregation Model With Core Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing carrier aggregation technology in mobile communications only distinguishes between primary and secondary component carriers, failing to effectively manage important secondary component carriers, which limits spectrum efficiency and management capabilities.
Innovation Solution
A carrier configuration method that includes configuring a carrier aggregation model with multiple component carriers, where at least one core carrier has uplink and downlink transmission functions, and allows for the designation of a primary core carrier that can be changed based on signal quality or load conditions, using physical layer or MAC layer signaling for notification and confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If carrier aggregation technology uses only primary and secondary component carrier roles, then the system structure is simple, but important secondary component carriers cannot be effectively managed
Solution Approach 1:
The patent segments the traditional binary carrier role structure (primary/secondary) into a multi-level hierarchy by introducing the concept of core carriers with different priorities. Component carriers are divided into primary core carriers and secondary core carriers, allowing differentiated management and prioritization of important carriers while maintaining structural organization.
Solution Approach 2:
The patent implements dynamic carrier role assignment where component carriers can transition between different core carrier roles based on network conditions, signal quality, and load requirements. The network device can dynamically adjust which carriers serve as primary or secondary core carriers, enabling flexible adaptation to changing transmission conditions.
2Productivity
If multiple component carriers are aggregated for data transmission, then spectrum efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments the carrier aggregation management function by introducing core carrier concepts that provide clear hierarchical organization. This segmentation allows the system to manage multiple aggregated carriers more efficiently by distinguishing between primary core carriers (which handle critical control functions) and secondary core carriers (which provide additional capacity), thereby reducing management complexity while maintaining high spectrum efficiency.
3Stability of the object's composition
If primary core carrier is fixed, then system stability is maintained, but adaptability to changing conditions deteriorates
Solution Approach 1:
The patent implements a dynamic carrier role assignment mechanism where the primary core carrier can be changed based on transmission conditions, signal quality, and network load. The network device can dynamically adjust which component carrier serves as the primary core carrier, enabling the system to adapt to changing conditions while maintaining operational stability through controlled transitions between carrier roles.
Solution Approach 2:
The patent changes the parameter of carrier role assignment from static to dynamic by introducing conditions for primary core carrier changes. The system monitors transmission conditions, signal quality, and load parameters, and adjusts the primary core carrier selection based on these parameter changes, allowing the system to adapt while maintaining stability through systematic parameter-based decision making.

AI summary
The present invention discloses a carrier configuration method and a device, and relates to the field of communications, to resolve a problem that dividing multiple component carriers into primary and secondary component carriers only is not conducive to management of an important secondary component carrier. In a specific solution, a carrier aggregation model is configured for UE, so that the UE performs data transmission with a network device according to the carrier aggregation model. The carrier aggregation model includes multiple component carriers, the multiple component carriers include at least one core carrier, and the at least one core carrier includes at least one primary core carrier. The core carrier has an uplink transmission function and a downlink transmission function. The primary core carrier has at least one of the following functions: a system message bearing function, a paging message bearing function, a semi-static scheduling parameter configuration function, a camping reference function, or an encryption reference function. The present invention is applied to a carrier configuration process.
