Solution Overview
Problem
Current communication systems, particularly in the context of LTE and New Radio (NR), face inefficiencies in managing and optimizing the transmission of data across multiple spatial relation information sets and SRS resource subsets, which affects the overall communication performance.
Innovation Solution
The implementation of a terminal and base station apparatus that utilizes a receiver to activate spatial relation information sets and applies specific transmission filters based on different spatial relation information subsets for PUCCH and PUSCH transmissions, as well as SRS resource indications to optimize data transmission across various slots and resource subsets.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple spatial relation information sets and SRS resource subsets are managed for PUCCH and PUSCH transmissions, then communication performance and adaptability are improved, but device complexity increases
Solution Approach 1:
The patent segments spatial relation information into multiple sets (first spatial relation information set, second spatial relation information set) and further divides them into subsets (first spatial relation information subset, second spatial relation information subset). Each subset is associated with specific SRS resources and transmission filters, allowing the terminal to manage complex spatial relations in an organized, modular manner. This segmentation enables the terminal to selectively apply different spatial relation information based on the transmission type (PUCCH or PUSCH) and slot configuration, thereby improving communication performance while maintaining manageable complexity through structured organization.
2Productivity
If multiple transmission filters are applied based on different spatial relation information for PUSCH in different slots, then data transmission performance is improved, but processing complexity increases
Solution Approach 1:
The patent applies different transmission filters based on local characteristics of each slot and spatial relation information subset. Specifically, for the first spatial relation information subset, a first transmission filter is applied to PUSCH in first slots, while for the second spatial relation information subset, a second transmission filter is applied to PUSCH in second slots. This local differentiation allows optimization of transmission performance for each specific slot and spatial relation combination, improving overall data transmission performance while managing processing complexity through targeted filter application rather than uniform processing.
3Productivity
If spatial relation information sets are activated and applied to different transmission channels, then communication efficiency is improved, but control complexity increases
Solution Approach 1:
The patent implements dynamic activation and application of spatial relation information sets based on transmission requirements. The terminal dynamically determines which spatial relation information set to apply based on the transmission type (PUCCH or PUSCH) and slot configuration. For example, when PUCCH is transmitted, the first spatial relation information set is applied, while for PUSCH in specific slots, the second spatial relation information set is applied. This dynamic approach allows the system to adapt to different communication scenarios, improving communication efficiency while managing control complexity through rule-based dynamic selection.

AI summary
Provided is a transmitter configured to transmit a PUCCH by applying a transmission filter based on any one piece of spatial relation information of a spatial relation information set, and transmit a PUSCH in a slot set by applying multiple transmission filters respectively based on multiple pieces of spatial relation information included in a spatial relation information subset of the spatial relation information set. The spatial relation information subset at least includes first spatial relation information and second spatial relation information different from the first spatial relation information. The transmitter applies a transmission filter of the multiple transmission filters based on the first spatial relation information to the PUSCH of a first slot subset of the slot set. The transmitter applies a transmission filter of the multiple transmission filters based on the second spatial relation information to the PUSCH of a second slot subset of the slot set.
