Network Coordinated Communication Reception Chain Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently transmitting data between terminals and multiple transmission nodes performing coordinated communication, leading to increased hardware and computational complexity, as well as interference issues.
Innovation Solution
The method involves a terminal receiving downlink control information from multiple transmission and reception points, using shared channels with overlapping time-frequency resources and demodulation reference signals, to reduce complexity and interference, while the transmission points transmit data based on specific DMRS associated with each channel.

Engineering Contradiction Analysis
1Reliability
If multiple transmission nodes perform coordinated communication with a terminal, then data transmission efficiency and reliability are improved, but reception hardware complexity and computational complexity increase
Solution Approach 1:
The patent segments the reception process by introducing separate reception chains for different transmission nodes. Each transmission node is assigned a dedicated reception chain that independently receives and processes signals from that specific node, preventing signal interference between nodes while maintaining coordinated communication benefits. This segmentation reduces the complexity of processing multiple overlapping signals simultaneously.
Solution Approach 2:
The patent introduces a network node as an intermediary that coordinates communication between multiple transmission nodes and the terminal. This intermediary manages the scheduling and coordination of transmissions from different nodes, allowing the terminal to receive signals in an organized manner without having to independently manage complex coordination logic, thereby reducing terminal complexity.

Solution Approach 1:

Each transmission node is assigned a dedicated reception chain that independently receives and processes signals from that specific node, preventing signal interference between nodes while maintaining coordinated communication benefits. This segmentation reduces the complexity of processing multiple overlapping signals simultaneously.
Solution Approach 2:
The patent applies preliminary action through advance scheduling and coordination by the network node. Before multiple transmission nodes transmit signals, the network coordinates the timing and resources to avoid overlapping transmissions that would cause interference. This preliminary coordination ensures efficient use of transmission resources while preventing harmful interference between nodes.
