1Productivity

If millimeter wave devices operate at very high carrier frequencies for high throughput wireless communications, then data throughput is improved, but propagation loss increases

Engineering Contradiction:

Improvedata throughputVSAvoidpropagation loss

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system segments the communication path by introducing relay devices that receive signals from source devices and forward them to destination devices. This segmentation allows millimeter wave communications to overcome high propagation loss by breaking the direct path into multiple shorter hops, each with lower individual loss

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Relay devices serve as intermediaries between source and destination devices. These relay devices equipped with distributed transceivers and array processing capabilities facilitate communication by receiving, processing, and retransmitting signals, thereby compensating for the high propagation loss inherent in millimeter wave frequencies

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If distributed transceivers with array processing are used in repeater networks, then communication performance is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple distributed transceivers are merged into a coordinated array system with centralized management. The array processing capability combines the functionality of individual transceivers to provide beamforming and spatial filtering, improving communication performance while managing complexity through unified control

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The relay devices are designed with multi-functional capabilities, serving as both receivers and transmitters, and providing both distributed transceiver functionality and array processing. This universality reduces overall system complexity by consolidating multiple functions into single relay nodes

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method in a relay device that comprises a plurality of antenna arrays, includes configuring first beamforming setting for first set of antenna arrays of the plurality of antenna arrays of the relay device to establish a first link between the relay device and a source device. A first data stream is received with a first beam pattern from the source device through the first link and a second data stream with a second beam pattern is forwarded to a destination device through second link without de-modulating the first data stream. The method includes phase shifting, by antenna array of the plurality of antenna arrays, an incoming signal stream and an outgoing signal stream by a different value for each element within the first set of antenna arrays to minimize an interference between the incoming signal stream and the outgoing signal stream, respectively, through the phase shifting.
