Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in supporting transmission efficiency, adaptive QoS, and efficient small cell cluster measurement/discovery, especially in multi-carrier environments, where non-CA capable and CA capable UEs need to be handled effectively.
Innovation Solution
The method involves determining message types based on predefined information for adaptive measurement, data processing, and power control, enabling CSI measurement, HARQ settings, and power boosting, and using message types to manage different UE behaviors and QoS requirements, including dynamic reservation requests and interference coordination among small cells.

Engineering Contradiction Analysis
1Productivity
If carrier aggregation is used to increase bandwidth and system capacity, then transmission rate and system capacity are improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent segments the carrier aggregation functionality into distinct components: primary cell (PCell) for control plane operations and secondary cells (SCells) for user plane data transmission. This segmentation allows the system to aggregate multiple carriers for increased capacity while managing complexity by separating control and data functions across different cell types.
Solution Approach 2:
The patent introduces a new dimension of operation by enabling simultaneous control plane and user plane transmissions across aggregated carriers. The primary cell handles control signaling while secondary cells provide additional data throughput, effectively adding a spatial/frequency dimension to the communication system without proportionally increasing control complexity.
2Productivity
If multiple control signals are used for multi-CC operation, then transmission efficiency is improved, but signal overhead and processing complexity increase
Solution Approach 1:
The patent implements universal control mechanisms that can operate across multiple component carriers. The primary cell's control signals are designed to coordinate transmissions across all aggregated carriers, providing multi-functional control that reduces the need for separate control channels on each carrier and thereby reduces overall signal overhead.
3Reliability
If adaptive measurement and power control are implemented for different message types, then QoS and transmission efficiency are improved, but processing complexity increases
Solution Approach 1:
The patent implements dynamic adaptation mechanisms where measurement and power control parameters are adjusted based on message type and channel conditions. The system dynamically switches between different measurement configurations and power control strategies depending on whether the transmission is control-plane or user-plane traffic, enabling QoS optimization without requiring completely separate processing paths for each message type.
