Simultaneous Multi-Carrier UE Transmission with Unified BWP Scheduling

Solution Overview

Problem

Existing communication systems face challenges with excessive signaling overhead due to the deployment of multiple carriers, each requiring separate signaling, leading to complex systems.

Innovation Solution

A method and apparatus that enable simultaneous transmission on multiple carriers within a single serving cell by configuring multiple bandwidth parts (BWPs) and utilizing downlink control information (DCI) to schedule physical downlink shared channels (PDSCH) or physical uplink shared channels (PUSCH) across these BWPs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple carriers are deployed using carrier aggregation or dual-connectivity, then simultaneous transmission capability is achieved, but signaling overhead increases and system complexity increases

Engineering Contradiction:

Improvesimultaneous transmission capabilityVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple carrier configurations into a single serving cell framework. Instead of treating each carrier as a separate serving cell with independent signaling, the invention combines them under one cell identity, allowing multiple carriers to be configured and managed within a single cell's signaling structure, thereby reducing overhead while maintaining simultaneous transmission capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention makes a single serving cell universal by enabling it to support multiple carriers simultaneously. The single serving cell structure is designed to handle multiple component carriers through unified resource allocation and signaling mechanisms, allowing one cell to perform the function previously requiring multiple separate cells

Inventive Principle:

Principle #6Universality (Multi-functionality)
