Solution Overview

Problem

In wireless communication systems that permit channel bonding, reduced-capability devices struggle to access and share communication resources due to the need for control information transmission that is compatible with both bonded and unbonded channels, particularly for devices that cannot perform channel bonding.

Innovation Solution

A wireless device method and system that selects a communication channel, identifies a designated control channel for control information, and listens for beacons to determine if the channel is bonded with others, allowing even non-capable devices to share resources by transmitting control information indicating bonding status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If channel bonding is permitted to enable wider bandwidth usage, then data throughput is improved, but device complexity increases and reduced-capability devices cannot access communication resources

Engineering Contradiction:
Improvedata throughputVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments communication channels into bonded channels (for high throughput) and control channels (for coordination). By separating data communication channels from control channels, the system allows reduced-capability devices to access control information and share resources without needing to handle complex bonded channel configurations themselves.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control channel acts as an intermediary between bonded channels and reduced-capability devices. Control information transmitted on the control channel provides bonding status and coordination data, enabling reduced-capability devices to understand and share resources in bonded channel configurations without directly managing the complexity of channel bonding.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If control information is transmitted on bonded channels, then coordination is improved, but reduced-capability devices cannot receive control information

Engineering Contradiction:
ImprovecoordinationVSAvoiddevice compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent separates control information transmission from data communication by designating specific control channels that are independent of bonded channel configurations. This segmentation ensures that control information is always available on dedicated channels that reduced-capability devices can access, regardless of whether data channels are bonded or not.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control channel serves multiple functions: it transmits coordination information for bonded channels, provides channel availability status, and ensures compatibility with both bonded and non-bonded devices. This universal control channel design ensures all devices, regardless of capability, can receive necessary control information.

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

3Productivity

If channel bonding is implemented to increase bandwidth, then data capacity is improved, but unauthorized bonding and resource conflicts increase

Engineering Contradiction:
Improvedata capacityVSAvoidunauthorized bonding
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where devices transmit control information indicating their bonding status and channel usage on the control channel. This feedback allows other devices to detect unauthorized bonding attempts and coordinate accordingly, preventing resource conflicts and ensuring reliable operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Before allowing channel bonding, the system performs preliminary actions by having devices first transmit control information on the control channel to declare their intended channel usage and bonding status. This preliminary coordination prevents unauthorized bonding and resource conflicts before they occur.

Inventive Principle:
Principle #10Preliminary action

AI summary

A wireless device (100) communicates in a wireless system by selecting a communication channel (202) for communication, identifying a control channel or control channels (204) designated for communication of control information for the selected communication channel, and listening for the control information (212) on the control channel to determine if the selected communication channel is bonded with any other communication channel. When control information is received via the control channel(s) indicating that the selected communication channel is bonded with at least one other communication channel, then the wireless device abstains from communication on the selected communication channel, or communicates in a narrowband mode. When control information is received via the control channel(s) indicating that the selected communication channel is not bonded with another communication channel, or when no control information is received via the control channel, then the wireless device communicates via the selected communication channel.
