CSI Resource Type Determination for Semi-Persistent Measurements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CSI measurement configuration structures in wireless communications fail to differentiate between CSI-RS and CSI-IM resource sets configured for semi-persistent PUCCH and PUSCH measurements, leading to ambiguity in activating or deactivating the correct resource sets.
Innovation Solution
A method is introduced to determine the type of CSI resource sets indicated in a MAC CE, using specific fields and numbering methods to distinguish between CSI-RS and CSI-IM resource sets for PUCCH and PUSCH measurements, allowing accurate activation or deactivation of corresponding resource sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified CSI measurement configuration structure is used for both PUCCH and PUSCH semi-persistent measurements, then the configuration process is simplified, but the terminal cannot differentiate between CSI-RS resource sets for PUCCH and PUSCH measurements
Solution Approach 1:
The patent segments the unified CSI measurement configuration into separate configuration structures for PUCCH and PUSCH semi-persistent measurements. By introducing distinct configuration containers (e.g., Spuci-Puci-Config and Spuci-Pusch-Config) with separate CSI-RS resource set lists, the system maintains simplicity while enabling clear differentiation between resource sets for different channel types.
2Productivity
If serial numbers are reused across different CSI resource set types, then the numbering is efficient, but ambiguity arises when activating resource sets
Solution Approach 1:
The patent resolves the ambiguity by adding a new dimension to the identification system. Instead of relying solely on serial numbers, each CSI-RS resource set is associated with a specific configuration container (PUCCH or PUSCH type). This dimensional separation allows serial numbers to be reused efficiently while maintaining unambiguous identification through the combination of configuration type and resource set index.

AI summary
The present disclosure provides in some embodiments a method for determining a CSI resource type, a network side device and a terminal. The method for determining the CSI resource type is applied to the terminal, and includes: receiving an MAC CE for activating/deactivating CSI resource sets; and determining types of the CSI resource sets indicated in the MAC CE, the types of the CSI resource sets including a first type for the measurement of a semi-persistent PUCCH and a second type for the measurement of a semi-persistent PUSCH.
