Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in supporting explosive data traffic, high per-user data rates, a large number of connected devices, very low end-to-end latency, and high-energy efficiency, particularly in next-generation mobile communication systems.
Innovation Solution
A method for receiving and transmitting data in a wireless communication system involves configuring bandwidth parts, activating specific bandwidth parts, and using scrambling and descrambling techniques for physical control and data channels, with distinct scrambling identification information for each control resource group, enabling efficient data transmission and reception even in joint transmission scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If joint transmission from multiple transmission points is implemented to increase data rate and capacity, then productivity is improved, but device complexity increases due to multiple control resource groups and scrambling management
Solution Approach 1:
The control resources are segmented into multiple control resource groups (first control resource group and second control resource group), each associated with different transmission points. This segmentation allows the terminal to manage multiple control resources independently, resolving the complexity by organizing resources into distinct groups rather than managing them as a single undifferentiated set.
Solution Approach 2:
Different scrambling identification information is assigned to different control resource groups, creating local differentiation. The first control resource group uses first scrambling identification information while the second control resource group uses second scrambling identification information. This local quality approach allows each transmission point to be uniquely identified and managed, reducing overall system complexity through localized differentiation.
2Reliability
If multiple control resource groups with distinct scrambling identification information are used to enable clear descrambling in joint transmission, then reliability is improved, but device complexity increases due to additional configuration information
Solution Approach 1:
The scrambling identification information is configured in advance for each control resource group before data transmission begins. The terminal receives and stores the first scrambling identification information for the first control resource group and the second scrambling identification information for the second control resource group. This preliminary configuration enables reliable descrambling operations without requiring complex real-time processing.
3Adaptability or versatility
If bandwidth part configuration and activation is implemented to support flexible resource allocation, then adaptability is improved, but device complexity increases due to additional configuration and activation management
Solution Approach 1:
The bandwidth part configuration enables dynamic resource allocation where specific bandwidth parts can be activated or deactivated based on transmission requirements. The terminal can switch between different bandwidth parts and their associated control resource groups, providing adaptability to changing transmission conditions while managing complexity through structured configuration states.

AI summary
A method for a terminal to receive data includes: a bandwidth part setting related step; a step for receiving control resource-related setting information about a physical control channel on the basis of the set BWP; a step for setting each of one or more control resources included in the setting information to a first control resource group or a second control resource group, and receiving a first physical control channel and a second physical control channel on the basis of the setting information; a step for receiving a first physical data channel on the basis of the first control resource group associated with the control resource in which the first physical control channel has been received; and a step for receiving a second physical data channel on the basis of the second control resource group associated with the control resource in which the second physical control channel has been received.
