Terminal Valid-Bit Determination for Multi-Panel Uplink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not support configuring different maximum numbers of transmission layers for multiple panels in scenarios of simultaneous multi-TRP/panel/beam transmission, leading to a lack of explicit methods for determining the number of bits in relevant information fields.
Innovation Solution
A method for a terminal device to determine the number of valid bits in a first information field based on maximum numbers of transmission layers associated with one or multiple spatial parameters, such as panels, beams, or TRPs, using spatial relationship information to adjust the number of bits in information fields like PTRS-DMRS association, TPMI, or SRI fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different maximum numbers of transmission layers are configured for multiple panels, then the adaptability of the communication system is improved, but the device complexity increases due to the need to determine bit allocation for multiple spatial parameters
Solution Approach 1:
The patent segments the bit determination process by spatial parameter type. Different information fields (PTRS-DMRS association, TPMI, SRI) have their bit counts determined independently based on their respective spatial parameters' maximum transmission layers, rather than using a unified complex calculation for all parameters simultaneously.
Solution Approach 2:
The patent applies local quality by allowing different maximum transmission layer configurations for different spatial parameters (panels). Each panel can have its own maximum transmission layers configured independently, enabling localized optimization without requiring uniform configuration across all panels.
2Measurement precision
If explicit methods are provided for determining the number of bits in information fields, then the measurement precision of transmission parameters is improved, but the ease of operation decreases due to additional determination steps
Solution Approach 1:
The patent implements preliminary action by pre-configuring the maximum transmission layers for each spatial parameter before actual transmission occurs. The terminal device determines the bit counts for information fields based on these pre-established configurations, avoiding the need for complex real-time calculations during transmission operations.
Solution Approach 2:
The patent utilizes parameter changes by dynamically adjusting the bit count of information fields according to the configured maximum transmission layers of associated spatial parameters. When maximum transmission layers change for a panel, the corresponding information field bit allocation automatically adjusts to match the new configuration.
