Find Innovative SolutionsGenerate Solutions
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 ranks in wireless communication.
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 through a clone pair configuration.

Engineering Contradiction Analysis
1Productivity
If the number of antennas and transmit/receive chains in user equipment is increased to improve peak data rate and MIMO rank, then data exchange rate and quality are improved, but device complexity and resource constraints worsen
Solution Approach 1:
The patent combines the capabilities of a primary user equipment and a secondary user equipment into a unified MIMO communication system. The primary UE and secondary UE share antenna resources and processing capabilities, effectively merging their transmit/receive chains to achieve higher peak data rates and MIMO ranks without requiring each individual device to have excessive hardware complexity.
Solution Approach 2:
The secondary user equipment serves multiple functions: it acts as both an independent communication device and as an auxiliary component for the primary UE's MIMO system. The secondary UE can dynamically switch between operating independently and cooperating with the primary UE, providing universal functionality that adapts to different network conditions and service requirements.
2Productivity
If peer-to-peer link is established between primary UE and secondary UE to aggregate MIMO data, then data exchange rate and quality are improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent introduces a peer-to-peer communication link as an intermediary channel between the primary UE and secondary UE. This direct link enables efficient data aggregation and coordination without requiring constant involvement of the network infrastructure, reducing signaling overhead while maintaining high data exchange rates through localized cooperation.
3Productivity
If secondary UE is utilized to enhance primary UE's MIMO capabilities, then peak data rate and rank are improved, but loss of time for establishing P2P link and coordination occurs
Solution Approach 1:
The patent implements mechanisms for preliminary discovery and selection of suitable secondary user equipment before high-rate data transmission is required. By pre-establishing potential cooperative relationships and maintaining readiness for P2P link activation, the system minimizes the time penalty associated with establishing connections when data rate enhancement is needed.

AI summary
Aspects of this disclosure relate to a pair of wireless communication devices wirelessly communicating with a network system in a coordinated manner. The wireless communication devices of the pair can be in communication with each other via a wireless peer-to-peer link. A primary wireless communication device can communicate a first part of a multiple-input multiple-output (MIMO) transmission via cellular communications and a second part of the MIMO transmission via the peer-to-peer link. This can enable the primary wireless communication device to communicate with the network system at a higher data rate and/or at a higher MIMO rank.
