Solution Overview

Problem

Current MIMO communication devices face limitations in simultaneously operating across multiple network channels due to resource constraints and inefficient mode transitions, which affect data throughput and network connectivity.

Innovation Solution

A method and device architecture that utilize multiple PHY transceiver cores to alternate between single and multiband communication modes, allowing simultaneous data transmission across different network channels by allocating specific transceiver cores for each channel and replicating MAC-related architecture to support concurrent operations.

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple PHY transceiver cores alternate between single and multiband communication modes, then network connectivity and adaptability are improved, but device complexity and resource management overhead increase

Engineering Contradiction:
Improvenetwork connectivityVSAvoidresource management overhead
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically transitions between single-band and multiband communication modes based on network conditions and requirements. The PHY transceiver cores can be allocated to different communication modes as needed, allowing the device to adapt its resource usage to match current operational demands, thereby improving network connectivity without permanently increasing complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The PHY transceiver cores are designed to perform multiple functions - they can operate in both single-band and multiband modes, and can be allocated to different communication tasks as required. This multi-functionality allows the same hardware resources to serve multiple purposes, reducing the need for dedicated resources for each mode and thereby managing complexity while maintaining versatility.

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

2Productivity

If PHY transceiver cores are allocated to specific network channels for simultaneous communication, then data throughput is improved, but resource allocation complexity increases

Engineering Contradiction:
Improvedata throughputVSAvoidresource allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system segments the available PHY transceiver cores into distinct groups that can be allocated to specific network channels. By dividing the resource pool into manageable segments, the system can simultaneously handle multiple communication tasks with dedicated resources for each, thereby improving data throughput while keeping the allocation process organized and manageable rather than monolithic and complex.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary allocation of PHY transceiver cores to specific network channels before simultaneous communication begins. This advance planning and assignment of resources ensures that when multiband communication starts, the resources are already properly configured and assigned, reducing the real-time complexity of resource management while maximizing throughput efficiency.

Inventive Principle:

AI summary

A system and method is presented to support simultaneous connections to multiple network connections. For example, a wireless radio of a communication device may be used to transmit or receive data from two network channels, each associated with a network connection. The communication device may allocate a first set of resources from the wireless radio to be used to communicate across a first network channel and allocate a second set of communication resources from the wireless radio to be used to simultaneously communicate a cross a second network channel.
