Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly in MIMO systems, face challenges in meeting high data traffic requirements due to limitations in the number of antennas, leading to restricted peak burstable speeds and network congestion, which affects user experience and data transmission quality.
Innovation Solution
The implementation of a method where a base station transmits data using a direct communication beam and multiple secondary communication beams, allowing neighboring wireless devices to relay data to the target device, and dynamically reconfigures communication beams based on performance levels and network load to achieve load balancing and enhance peak burstable speeds without increasing antenna size.

1Productivity
If multiple communication beams are used to increase transmission capacity, then data traffic requirements can be met, but the number of antennas required increases prohibitively
Solution Approach 1:
The patent introduces a mesh network of wireless devices as intermediaries to relay communication beams. Instead of requiring the base station to directly transmit multiple high-order MIMO beams to each device, the system uses neighboring wireless devices as relay nodes to forward beams, effectively multiplying the number of available communication paths without increasing antenna counts at any single location.
Solution Approach 2:
The patent transitions from a two-dimensional antenna array problem to a three-dimensional spatial network problem. By utilizing the mesh network topology and multi-hop relaying through wireless devices in different spatial locations, the system creates additional communication dimensions that allow high-order MIMO performance without requiring proportionally more antennas at each node.
2Speed
If the number of antennas at wireless devices is increased to support higher order MIMO, then peak burstable speeds increase, but the device size becomes prohibitively large
Solution Approach 1:
The patent moves the antenna requirement from the device level to the network level. Individual wireless devices maintain small antenna counts suitable for portable form factors, while the aggregate network capacity achieves high-order MIMO performance through coordinated multi-device participation in the mesh network.
Solution Approach 2:
Wireless devices in the mesh network serve multiple functions: they act as end-user devices, relay nodes for other devices, and contributors to the overall MIMO capacity. This multi-functionality allows the system to achieve high transmission speeds without requiring each device to have large antenna arrays.
3Area of stationary object
If communication beams are configured for specific coverage areas, then network coverage is provided, but wireless devices cannot receive services from other communication beams
Solution Approach 1:
The patent uses wireless devices within the mesh network as intermediary relays to extend service access. A wireless device in one coverage area can receive and forward communication beams from other coverage areas, allowing end devices to access services from multiple beams without direct line-of-sight or requiring multiple antennas for each beam.

AI summary
Techniques are described for enhancing wireless communication using millimeter wave (mmW) communication and mesh network topology. One method includes transmitting data to a first wireless device via a first mmW communication beam from a base station, determining that a performance level of the first mmW communication beam is below a threshold value based on transmitting the data, and communicating with the first wireless device over a transmission route based on a performance level of a second mmW communication beam. In some examples, the transmission route includes a first segment that includes the second mmW communication beam and a second segment that includes a wireless mesh network.
