Solution Overview

Problem

In wireless communication systems, effectively transmitting signals using multiple resources is challenging due to the need for efficient allocation and synchronization of information and reference signals across different resource blocks, which affects system performance and reliability.

Innovation Solution

A method and apparatus for signal transmission in wireless communication systems, where a transmitter generates information sequences based on transmission symbols and resource indices, and a reference signal generator produces a reference signal sequence depending on the identity of resource blocks, enabling effective transmission of signals across multiple resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple resource blocks are aggregated to increase transmission bandwidth for high-speed data transfer, then data transfer rate is improved, but signal transmission reliability and synchronization across different resource blocks deteriorates

Engineering Contradiction:
Improvedata transfer rateVSAvoidsignal transmission reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent changes the parameter of reference signal sequence generation by introducing a resource block-dependent variation. The reference signal sequence is generated differently based on the identity of the resource block, which optimizes signal transmission reliability across aggregated resource blocks while maintaining high data transfer rates. This parameter change allows the system to adapt reference signal characteristics to specific resource block configurations.

Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent applies local quality by making the reference signal sequence generation dependent on the specific resource block identity. Each resource block can have optimized reference signal characteristics tailored to its local properties, which improves overall system performance without requiring complex centralized management of all resource blocks. This localized approach simplifies resource allocation while maintaining synchronization.
