Wireless Network Resource Assignment Priority for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in providing equal resource allocation to User Equipment (UEs) operating with and without carrier aggregation, leading to disparities in service quality and ramp-up times.
Innovation Solution
The method involves determining the operational mode of UEs within the network, where UEs operating without carrier aggregation are given higher priority for resource assignment on a given carrier or resource set, allowing them to ramp up more quickly and achieve similar resource availability as those with carrier aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If equal priority resource assignment is given to all UEs, then resource allocation simplicity is maintained, but service quality disparity occurs between UEs with and without carrier aggregation
Solution Approach 1:
The patent applies local quality by differentiating resource assignment priority based on the specific characteristics of each UE. UEs without carrier aggregation are identified and given higher priority on specific carriers where they can operate, while UEs with carrier aggregation receive standard priority. This localized differentiation ensures that each UE type receives appropriate resource allocation tailored to its capabilities, resolving the service quality disparity while maintaining overall system manageability.
2Loss of time
If priority resource assignment is given to UEs without carrier aggregation, then their ramp-up time is reduced, but resource allocation complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-identifying UEs that operate without carrier aggregation and pre-assigning them higher priority resource allocation. The base station determines which UEs are capable of carrier aggregation and configures priority rules in advance. When resources become available, these pre-identified UEs automatically receive preferential treatment without requiring real-time complex decision-making, thus reducing their ramp-up time while keeping the allocation mechanism relatively simple through pre-established rules.
3Productivity
If carrier aggregation is supported for all UEs, then resource utilization efficiency is improved, but compatibility issues arise with legacy UEs
Solution Approach 1:
The patent applies dynamics by making the resource assignment priority flexible and adaptive based on UE capabilities. The base station dynamically determines which UEs support carrier aggregation and adjusts priority levels accordingly. This dynamic approach allows the system to optimize resource utilization for advanced UEs that can leverage carrier aggregation while simultaneously providing enhanced priority support to legacy UEs without carrier aggregation capability, ensuring broad compatibility across different UE types.

AI summary
A method and system for assigning resources to user equipment devices (UEs) is disclosed. A communication system may include a wireless network that allocates, among a plurality of UEs, resources on a given carrier. The wireless network may support carrier aggregation using a combination of the given carrier and at least one other carrier. The method involves the wireless network making a determination that (i) a first UE is operating without carrier aggregation and (ii) a second UE is operating with carrier aggregation. The method further involves, in response to making the determination, the wireless network giving the first UE higher priority than the second UE for resource assignment on the given carrier.
