Wireless Transmit Mode Switching for Bandwidth-Constrained Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face constraints in electromagnetic spectrum availability, limiting their ability to transmit and receive voice, data, and multimedia content effectively and at satisfactory rates due to bandwidth limitations.
Innovation Solution
A base station communicates with a destination device and auxiliary devices, assigning them reference indices to convey N bits of information indirectly through a selected auxiliary device, allowing the destination device to augment the N bits with L bits, thereby transmitting N+L bits without directly conveying L bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station transmits more bits directly to the destination device, then the data rate increases, but the bandwidth consumption increases
Solution Approach 1:
The patent introduces auxiliary devices as intermediaries between the base station and destination device. The base station transmits N bits to an auxiliary device, which then relays them to the destination device. This intermediary approach allows implicit communication where the destination device can infer additional L bits from the auxiliary device's identity or state, achieving N+L bits effective data rate while only consuming bandwidth for N bits transmission.
Solution Approach 2:
The patent adds a new dimension to the communication system by introducing auxiliary devices with unique identities or states. Instead of only direct base station to destination communication, the system now uses the auxiliary device dimension (identity, location, or state) to carry implicit information. This dimensional expansion allows the destination device to extract additional information beyond what is explicitly transmitted.
2Quantity of substance
If the base station uses auxiliary devices to relay information, then bandwidth efficiency improves, but the device complexity increases
Solution Approach 1:
The auxiliary devices serve multiple functions: they act as signal relays for N bits transmission, carry implicit information through their identity or state representing L bits, and can potentially serve as destination devices themselves. This multi-functionality reduces the need for separate dedicated components for different communication tasks, thereby managing complexity while achieving bandwidth efficiency.
3Length of stationary object
If the base station transmits information through auxiliary devices, then communication range extends, but the loss of information increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing associations between auxiliary devices and their identities or states before actual data transmission. The destination device is pre-configured with knowledge of auxiliary device identities and their corresponding information representations. This preliminary setup ensures that when N bits are transmitted through an auxiliary device, the destination device can reliably reconstruct the full N+L bits without information loss, even over extended communication ranges.
