Wireless Terminal Control Resource Grouping for Joint Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing data transmission and reception, particularly in joint transmission scenarios where multiple transmission points (TPs) and/or transmission and reception points (TRPs) are involved, leading to ambiguity in terminal operations and interference between data channels.
Innovation Solution
The proposed method involves configuring control resources into distinct groups, such as first and second control resource groups, to enable separate transmission and reception of physical control channels and data channels. This method includes receiving configuration information related to control resources, distinguishing between different control resource groups, and performing scrambling and descrambling operations based on specific parameter information associated with each group.

Engineering Contradiction Analysis
1Productivity
If multiple transmission points (TPs) and/or transmission and reception points (TRPs) are used for joint transmission, then data transmission capacity is improved, but interference between data channels increases and terminal operation ambiguity occurs
Solution Approach 1:
The patent segments control resources into distinct groups (first control resource group and second control resource group), each associated with different transmission points. This segmentation allows the terminal to separately receive and process control information from different TPs/TRPs, reducing interference and ambiguity while maintaining high data transmission capacity through joint transmission.

AI summary
A method by which a terminal receives data in a wireless communication system can comprise the steps of: receiving configuration information relating to a control resource of a physical control channel; allowing one or more control resources included in the configuration information to be respectively set 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 configuration information; receiving a first physical data channel on the basis of the first control resource group related to a control resource in which the first physical control channel is received; and receiving a second physical data channel on the basis of the second control resource group related to a control resource in which the second physical control channel is received.
