TRP Identifier Segmentation for Multi-TRP Control Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-TRP transmission scenarios, there is no effective solution to distinguish control information of different Transmission Reception Points (TRPs) in existing technologies, leading to potential obfuscation of control information.
Innovation Solution
A transmission method that uses TRP identifier information to determine the target TRP for each piece of control information, allowing network devices to differentiate and decode control information from multiple TRPs by associating unique identifiers with each TRP, such as CORESET identifiers, predefined identifiers, field values in DCI, search space identifiers, or cell radio network temporary identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-TRP transmission is implemented to improve transmission reliability, then transmission reliability is improved, but control information distinguishability deteriorates
Solution Approach 1:
The patent segments control information by associating each TRP with a unique identifier (such as CORESET ID, search space ID, or DCI field values). This segmentation allows the network device to distinguish control information from different TRPs even when transmitted through the same uplink channel, thereby maintaining control information distinguishability while enabling multi-TRP transmission for improved reliability
Solution Approach 2:
The patent applies local quality by assigning specific identifier characteristics to different TRPs. Each TRP is associated with unique identifier values (e.g., different CORESET IDs, different search space IDs, or specific DCI field combinations), allowing the network device to locally identify and process control information from each TRP individually based on these unique local qualities
2Productivity
If multiple TRPs send control information through the same uplink channel, then transmission efficiency is improved, but control information identification becomes difficult
Solution Approach 1:
The patent introduces TRP identifier information as an intermediary element that mediates between multiple TRPs transmitting through the same uplink channel. This intermediary (the identifier associated with each TRP) enables the network device to differentiate and identify control information from different TRPs without requiring separate physical channels, thus maintaining transmission efficiency while solving identification difficulties

AI summary
Embodiments of the present disclosure provide a transmission method, a terminal, a network device, and a computer-readable storage medium. The transmission method may be performed by a terminal or a network device. The transmission method performed by the terminal includes sending at least one piece of control information by using a target uplink channel, where each piece of control information corresponds to Transmission Reception Point (TRP) identifier information, the TRP identifier information is used to determine a target TRP corresponding to the control information, and the target TRP is one TRP in multi-TRP transmission.
