Solution Overview

Problem

The wireless communication industry faces challenges in utilizing millimeter wave (mmW) communication for mobile communications, particularly in outdoor environments due to high RF propagation loss and the need for line-of-sight scenarios, limiting its coverage and efficiency.

Innovation Solution

A network coordination method is implemented using an anchor node to manage resource assignments across different base station devices, including mmW BS devices, macro cell BS devices, and small cell BS devices, employing frequency division duplex communication to optimize spectrum utilization and provide wider area coverage by coordinating downlink and uplink channels dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If mmW communication is used for mobile communications, then high-speed communication is achieved, but coverage area is limited due to high RF propagation loss and line-of-sight requirements

Engineering Contradiction:
Improvecommunication speedVSAvoidcoverage area
Core Design Contradiction:
SpeedVSArea of stationary object

Solution Approach 1:

The patent introduces an anchor node as an intermediary between mmW base stations and mobile devices. The anchor node receives service requests from mobile devices, determines appropriate transmission parameters, and coordinates resource assignments across multiple base stations. This mediator enables seamless coordination between mmW and non-mmW base stations, allowing high-speed mmW communication to be combined with broader coverage from other base station types, thereby resolving the contradiction between communication speed and coverage area.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If mmW communication is deployed, then network capacity is improved, but service reliability deteriorates in outdoor environments due to propagation challenges

Engineering Contradiction:
Improvenetwork capacityVSAvoidservice reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic resource assignment and handover coordination through the anchor node. The system dynamically determines transmission parameters based on real-time conditions, including whether to assign mmW base stations for downlink channels and non-mmW base stations for uplink channels. This dynamic adaptation allows the network to optimize for high capacity when conditions permit while maintaining reliability by switching to more robust non-mmW connections when propagation conditions are poor, thus resolving the contradiction between network capacity and service reliability.

Inventive Principle:
Principle #15Dynamics

3Quantity of substance

If separate uplink and downlink channels are assigned to different base stations, then spectrum utilization is enhanced, but system complexity increases

Engineering Contradiction:
Improvespectrum utilizationVSAvoidsystem complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The anchor node is designed as a universal coordination entity that handles multiple functions: receiving service requests from mobile devices, determining transmission parameters, coordinating resource assignments across different base station types, and managing handovers. By consolidating these diverse coordination functions into a single multi-functional anchor node, the system achieves enhanced spectrum utilization through flexible uplink/downlink assignment while avoiding the complexity that would arise from distributing these coordination functions across multiple separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Harmonization of wireless communication service delivery is facilitated. One method comprises receiving, by an anchor node, from a mobile device communicatively coupled to a network, first information indicative of a request for service for the mobile device, wherein the network comprises a first base station (BS) device configured to provide downlink communication between the first BS device and the mobile device, and another BS device configured for uplink communication between the mobile device and the other BS device. The first BS device can be a millimeter wave (mmW) BS device in some embodiments. The method also comprises generating information indicative of a transmission parameter for a type of access to the network device. The transmission parameter can be generated based on various criteria including, but not limited to, whether there is line-of-sight between the first device and the mobile device, the requested service and/or the availability of network resources.
