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.

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
