Wireless Communication Device Dual Connectivity Setup

Solution Overview

Problem

In wireless communication systems, there is a delay before starting communication using multiple carriers due to the need for terminal devices to transition from non-communication modes to communication modes and then perform radio measurements to add cells or carriers, which affects throughput.

Innovation Solution

The system allows for the selection and pre-configuration of primary and secondary base stations in non-communication modes, enabling immediate data communication upon transitioning to communication mode through dual connectivity or carrier aggregation by utilizing a control unit in both base station and terminal devices to manage control and user planes across multiple cell groups.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If terminal devices perform radio measurements to add cells or carriers after transitioning from non-communication modes, then communication reliability is improved, but communication delay increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidcommunication delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the terminal device perform radio measurements and identify suitable cells or carriers while in non-communication modes (RRC idle or inactive states). The measurement results and candidate cell information are stored in advance, so when the terminal transitions to communication mode, the network can immediately configure dual connectivity or carrier aggregation without requiring new measurements, thus reducing communication delay while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses measurement results obtained in non-communication modes as an intermediary. These pre-obtained measurement results serve as a bridge between the terminal's idle state and the network's connection configuration, allowing the network to make informed decisions about dual connectivity or carrier aggregation setup without requiring real-time measurements during the transition to communication mode

Inventive Principle:

Principle #24Intermediary (Mediator)
