Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for carrier aggregation in wireless networks do not adequately consider the various usage types of wireless devices and characteristics of component carriers, leading to suboptimal selection of carriers for improving service quality and coverage.
Innovation Solution
A system and method for performing carrier aggregation that identifies the usage type of an application on a wireless device and correlates it with carrier characteristics such as large coverage area or high throughput, instructing the device to operate in carrier aggregation mode using a primary and secondary carrier based on these characteristics.

1Reliability
If carrier aggregation is implemented without considering usage types, then service quality can be improved through multiple carriers, but carrier selection becomes suboptimal and cannot adequately meet diverse application requirements
Solution Approach 1:
The system dynamically adapts carrier aggregation configuration based on real-time usage type detection. The network node identifies the usage type of applications on the wireless device and dynamically selects appropriate component carriers (primary and secondary) from available carriers with different characteristics, making the carrier aggregation adaptive rather than static.
Solution Approach 2:
The patent applies different carrier characteristics to different usage types. Low-frequency carriers with large coverage areas are selected for usage types requiring wide coverage (e.g., voice, messaging), while high-frequency carriers with high throughput are selected for usage types requiring high data rates (e.g., video streaming, gaming). This matches specific carrier qualities to specific application requirements.
2Productivity
If different frequency bands are used for carrier aggregation, then both coverage area and throughput can be utilized, but carriers with different frequencies have different characteristics making selection challenging
Solution Approach 1:
The wireless device autonomously reports its usage type to the network node, enabling the network to automatically select the appropriate carrier aggregation configuration without manual intervention or complex centralized decision-making. The device essentially serves itself by providing usage type information that guides the network's carrier selection.
Solution Approach 2:
The system changes carrier selection parameters (primary carrier frequency, secondary carrier frequency) based on usage type parameters. Different usage types trigger different carrier configurations, with parameters such as carrier frequency, bandwidth, and aggregation mode being adjusted according to the identified application requirements.

AI summary
Systems, methods, and processing nodes for performing carrier aggregation in a wireless network include associating a primary usage type of an application running on a wireless device with a characteristic of a first carrier based on at least a first frequency band utilized by the first carrier, associating a secondary usage type of the application with a characteristic of a second carrier based on at least a second frequency band utilized by the second carrier, assigning the first carrier as a primary carrier for the wireless device when operating in a carrier aggregation mode, and assigning the second carrier as a secondary carrier for the wireless device when operating in the carrier aggregation mode.
