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 assigns a reference index to an auxiliary device, conveying N bits of information indirectly through the auxiliary device, which augments the transmission with L bits to achieve N+L bits at the destination device, without directly transmitting L bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless systems transmit more voice, data and multimedia content to meet user demand, then service quality and user satisfaction improve, but electromagnetic spectrum bandwidth requirements increase beyond available capacity
Solution Approach 1:
The patent introduces an auxiliary device as an intermediary between the base station and destination device. The base station transmits N bits to the auxiliary device, which then transmits N+L bits to the destination device. This intermediary approach allows the system to convey more information (N+L bits) than the base station directly transmits (N bits), effectively increasing data transmission rate without proportionally increasing base station bandwidth usage.
Solution Approach 2:
The patent utilizes the spatial dimension by introducing an auxiliary device at a different location in the communication network. Instead of increasing bandwidth in the frequency dimension, the system adds a spatial dimension to the transmission path, allowing information to be conveyed through multiple hops (base station → auxiliary device → destination device), thereby achieving higher effective data rates without proportionally increasing spectrum bandwidth.
2Loss of information
If the base station transmits N bits directly to the destination device, then transmission simplicity is maintained, but the total information conveyed (N bits) is less than what could be achieved through auxiliary devices (N+L bits)
Solution Approach 1:
The auxiliary device serves as a mediator that enables information augmentation. The base station sends N bits to the auxiliary device, which then sends N+L bits to the destination device. The auxiliary device effectively adds L bits of information to the transmission without requiring the base station to directly transmit those L bits, thereby reducing information loss while managing complexity through distributed processing.
Solution Approach 2:
The transmission process is segmented into two independent hops: base station to auxiliary device (N bits), and auxiliary device to destination device (N+L bits). This segmentation allows each segment to be optimized independently, with the auxiliary device handling the additional L bits of information, thereby achieving higher total information conveyance without proportionally increasing overall system complexity.
3Quantity of substance
If auxiliary devices are introduced to convey N+L bits while base station transmits only N bits, then bandwidth efficiency improves, but device complexity and coordination requirements increase
Solution Approach 1:
The auxiliary device as an intermediary simplifies the bandwidth efficiency problem by locally handling the augmentation of L bits. The base station only needs to transmit N bits over the wideband connection, and the auxiliary device handles the additional L bits locally when relaying to the destination device. This distributes complexity to the auxiliary device rather than requiring complex base station processing, thereby improving bandwidth efficiency while managing system complexity through distributed architecture.
