1Productivity
If multiple parameter lists are configured for different BWPs, then communication efficiency and resource utilization are improved, but device complexity and configuration management become more complex
Solution Approach 1:
The patent segments the parameter configuration by creating separate parameter lists (first parameter list for initial BWP, second parameter list for non-initial BWP) that can be independently configured and applied to different bandwidth parts. This allows each BWP to have optimized parameters tailored to its specific function, improving communication efficiency while keeping the complexity manageable through structured organization.
Solution Approach 2:
The patent applies different parameter configurations to different BWPs based on their specific requirements. The first parameter list is applied to the initial BWP for system information transmission, while the second parameter list is applied to non-initial BWPs for other purposes. This local optimization allows each BWP to operate with parameters best suited to its function, improving overall system performance.
2Speed
If default tables are applied for PDSCH time domain resource allocation, then resource allocation speed is improved, but flexibility in resource allocation is reduced
Solution Approach 1:
The patent implements a dynamic resource allocation mechanism where the system can switch between using default tables for quick allocation and using configured parameter lists for customized allocation. The controller determines whether to use default tables or configured parameter lists based on the specific BWP and communication requirements, providing both speed and flexibility in resource allocation.
Solution Approach 2:
The patent changes the allocation parameters dynamically by selecting different parameter lists based on the BWP type. For initial BWP, the first parameter list is used, while for non-initial BWPs, the second parameter list is used. This parameter variation allows the system to adapt resource allocation to different operational contexts, balancing speed and flexibility.

AI summary
A terminal apparatus receives first DCI with an SI-RNTI and receives a SIB in a first time resource in a first BWP, and receives second DCI with an RA-RNTI and receives an RAR in a second time resource in a second BWP, and determines the first time resource, using a first value included in the first DCI and a first configuration, and determines the second time resource, using a second value included in the second DCI and a second configuration. In a case that a second parameter list is provided in the SIB, the terminal apparatus applies the second parameter list to the second configuration. In a case that the second parameter list is not provided, the terminal apparatus applies a first parameter list or a first default table.
