Solution Overview

Problem

Multiple-input multiple-output (MIMO) wireless communication systems face limitations in data rate and quality due to the number of antennas and transmit/receive chains in user equipment, restricting peak data rates and quality of service.

Innovation Solution

Establishing a peer-to-peer (P2P) link between a primary user equipment (UE) and a secondary UE to aggregate and process MIMO data, enabling higher data rates and ranks by utilizing the combined capabilities of both UEs, including coordinated transmission and reception of MIMO data and joint processing at the physical layer.

1Productivity

If the number of antennas and transmit/receive chains in user equipment is increased to improve peak data rate and MIMO rank, then the data rate and quality of service are improved, but the device complexity and cost increase

Engineering Contradiction:

Improvepeak data rateVSAvoidnumber of antennas and transmit/receive chains

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the capabilities of multiple user equipment devices into a unified MIMO system. A first UE and second UE work together as a coordinated pair, where the second UE assists the first UE in receiving and processing MIMO transmissions. This merging of resources allows the system to achieve higher MIMO ranks and data rates without requiring each individual device to have more antennas or transmit/receive chains.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The second UE serves multiple functions: it acts as both an independent communication device and as a helper device for the first UE. The second UE can receive MIMO transmissions independently while also assisting the first UE by receiving additional spatial layers and forwarding them to the first UE via peer-to-peer communication. This multi-functionality maximizes the utility of available hardware resources.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If the number of antennas and transmit/receive chains is increased to improve MIMO rank, then the quality of service is improved, but the device complexity increases

Engineering Contradiction:

Improvequality of serviceVSAvoidnumber of antennas and transmit/receive chains

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system merges the antenna resources of two UEs to achieve higher MIMO rank. The first UE uses its antennas to receive certain spatial layers while the second UE uses its antennas to receive additional spatial layers. By combining the reception capabilities of both devices and coordinating their processing, the system achieves higher quality of service without requiring either device to have a large number of antennas.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The second UE acts as an intermediary that receives MIMO transmissions from the base station, processes them, and forwards relevant data to the first UE via peer-to-peer communication. This intermediary role allows the system to achieve higher MIMO ranks by distributing the reception and processing tasks across multiple devices rather than requiring a single device with many antennas.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Device complexity

If standalone user equipment operations are used to maintain simple device architecture, then device complexity is reduced, but peak data rate and MIMO rank are limited

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system adds a new dimension to MIMO communication by introducing peer-to-peer communication between UEs. Instead of only communicating with the base station, UEs can now communicate directly with each other to share received spatial layers. This additional communication dimension enables higher effective MIMO ranks without increasing the antenna count of individual devices.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Productivity

If additional user equipment is added to form a coordinated pair for higher data rates, then peak data rate and MIMO rank are improved, but the system complexity increases

Engineering Contradiction:

Improvepeak data rateVSAvoidsystem architecture

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system segments the MIMO reception function across multiple UEs. Instead of one UE handling all reception tasks, the first UE and second UE divide the work by receiving different spatial layers independently. This segmentation reduces the processing burden on each individual device while achieving higher overall system throughput through coordinated operation.

Inventive Principle:
