5G Transmit/Receive Mode Selection for Spectrum Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face constraints in electromagnetic spectrum availability, limiting their ability to effectively transmit and receive voice, data, and multimedia content at satisfactory rates.
Innovation Solution
A base station communicates with a destination device and assigns a reference index to an auxiliary device, which relays additional information bits to the destination device, allowing the destination device to augment the received data with predetermined bits, thereby conveying more information without direct transmission of all bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless systems transmit more data directly, then data transmission rate improves, but electromagnetic spectrum availability is insufficient
Solution Approach 1:
The patent introduces auxiliary devices as intermediaries between the base station and destination device. These auxiliary devices receive data from the base station and relay it to the destination device, enabling indirect data transmission that bypasses the limitation of available electromagnetic spectrum for direct transmission.
Solution Approach 2:
The patent transitions from a single-dimension direct transmission model to a multi-dimensional relay transmission model. By utilizing auxiliary devices as intermediate nodes, the system adds spatial and functional dimensions to the transmission path, allowing data to flow through multiple hops rather than requiring a single direct channel.
2Productivity
If auxiliary devices are introduced for implicit information conveyance, then bandwidth efficiency improves, but device complexity increases
Solution Approach 1:
The auxiliary devices serve as mediators that simplify the overall system architecture by handling data relay functions. Instead of requiring the base station to directly manage multiple destination devices with limited spectrum, the auxiliary devices absorb the complexity of intermediate processing and forwarding.
Solution Approach 2:
The auxiliary devices autonomously perform data relay operations without requiring complex centralized control for each transmission. They independently receive data from the base station, process it according to predefined protocols, and forward it to the destination device, reducing the control complexity at the base station.

AI summary
A plurality of transmit/receive modes is established and is used selectively to communicate responsive to a parameter that is associated with data to be transmitted/received; and wirelessly communicating by using a 5G air interface and by using at least one transmit/receive mode of the plurality of transmit/receive modes. Only one transmit/receive mode is selected and used at any one time to communicate; wherein the transmit/receive mode that is used is selected responsive to said parameter that is associated with data to be transmitted/received. The plurality of transmit modes differ from one another in frequencies, subcarriers, a Fourier transform, an inverse Fourier transform, an antenna configuration, a power level and/or a physical layer of an air interface being used. The plurality of receive modes also differ from one another.
