Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in efficiently increasing throughput for users without the need for costly new network deployments, as existing networks have limited maximum supported data rates.
Innovation Solution
Implementing multi-carrier operation in GSM networks, where mobile stations can receive and transmit data on multiple carriers simultaneously, allowing for dynamic assignment of carriers and time slots based on availability and data requirements, enhancing data transmission capabilities.

Engineering Contradiction Analysis
1Speed
If new network deployment is implemented to increase maximum supported data rate, then data rate is improved, but capital expenditure and deployment complexity increase
Solution Approach 1:
The patent implements dynamic carrier allocation where mobile stations are assigned multiple carriers based on real-time data requirements and network conditions. The system dynamically adjusts the number of carriers and time slots allocated to each user, enabling flexible adaptation without physical network changes. This dynamic resource allocation allows existing networks to achieve higher data rates by optimizing spectral efficiency rather than deploying new infrastructure.
Solution Approach 2:
The patent changes the operational parameters of existing carriers by enabling multi-carrier operation where mobile stations simultaneously receive and transmit on multiple carriers. The system modifies parameters such as carrier assignment, time slot allocation, and transmission power distribution across multiple carriers, thereby increasing effective data rate without requiring new network deployment.
2Productivity
If multi-carrier operation is implemented, then throughput is improved, but device complexity increases
Solution Approach 1:
The patent segments the communication resource into multiple carriers and time slots, allocating different segments to different mobile stations simultaneously. Each mobile station receives data on multiple carriers but processes them through organized segmentation of time slots and resource blocks, managing complexity through structured resource division rather than simultaneous unstructured processing.
Solution Approach 2:
The patent makes existing single-carrier GSM infrastructure multi-functional by enabling it to simultaneously support multiple carriers for different users. The network infrastructure, originally designed for single-carrier operation, is enhanced to perform multiple functions: simultaneous data transmission on multiple carriers, dynamic resource allocation, and multi-user support, thereby increasing throughput without proportionally increasing device complexity.
