Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of user equipment (UEs) and data/control information in wireless communication systems poses a challenge due to limited radio resources, necessitating an efficient method for transmitting and receiving uplink/downlink signals and control information.
Innovation Solution
A method where a base station informs user equipment (UE) of multiple cell sets and parameter sets, allowing the UE to receive or transmit signals using specific parameter sets based on provided information, enhancing signal processing and resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple cell sets and parameter sets are configured for UE, then signal processing efficiency and resource management improve, but device complexity and processing overhead increase
Solution Approach 1:
The patent divides the cell set into multiple groups (first cell set and second cell set) with different parameter configurations. Each cell set has associated parameter sets that can be independently activated, allowing the UE to process only relevant parameters for active cells rather than all possible parameters, thus improving efficiency while managing complexity through structured organization.
Solution Approach 2:
The patent implements dynamic switching between different parameter sets based on which cell set is currently active. The UE can dynamically activate or deactivate parameter sets corresponding to different cell sets, allowing adaptive resource allocation and processing optimization without permanently maintaining all parameter configurations, thereby balancing efficiency and complexity.
2Productivity
If carrier aggregation technology is used to aggregate multiple UL/DL frequency blocks, then data throughput increases, but system complexity and resource management difficulty increase
Solution Approach 1:
The patent segments the aggregated carriers into different cell sets with distinct parameter configurations. Each cell set can be independently managed and activated, allowing the system to handle multiple frequency blocks efficiently without requiring complex simultaneous processing of all carriers, thus maintaining throughput while reducing management complexity.
Solution Approach 2:
The patent creates a universal framework where a single UE can operate with multiple parameter sets corresponding to different cell sets. This multi-functional capability allows the UE to adapt to different carrier aggregation configurations without requiring separate processing mechanisms for each scenario, simplifying the overall system complexity while supporting high throughput.
3Productivity
If the number of UEs served in a prescribed resource region increases, then network capacity and service coverage improve, but available resources per UE decrease and resource allocation complexity increases
Solution Approach 1:
The patent segments the network resources by organizing cells into different cell sets with dedicated parameter sets. This segmentation allows for more granular resource allocation and enables the system to serve multiple UEs with different parameter configurations simultaneously, increasing network capacity while managing allocation complexity through structured resource organization.

AI summary
A method for receiving, by a user equipment, a downlink signal, the method includes receiving, by the user equipment from a serving cell, discovery signal based radio resource measurement information for a cell different from the serving cell; receiving, by the user equipment from the cell, a discovery signal of the cell at discovery signal transmission periodicity based on the discovery signal based radio resource measurement information; and performing, by the user equipment, reference signal received power, RSRP, measurement for the cell based on the discovery signal.
