Uplink Transmission Resource Determination via Preconfigured RB Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal equipment may struggle to determine the correct resource for uplink transmission when scheduled on an uplink bandwidth part with multiple resource block sets, leading to incorrect transmission and reception of uplink data.
Innovation Solution
The proposed solution involves an uplink transmission method where the terminal equipment receives indication information without an indication field for resource block sets and transmits on predefined or preconfigured resource block sets, ensuring correct resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the uplink bandwidth part includes at least two resource block sets and the indication information does not include an indication field for resource block sets, then the terminal equipment can simplify the indication information structure, but the terminal equipment may be unable to determine the correct resource for uplink transmission
Solution Approach 1:
The patent applies preliminary action by preconfiguring resource block sets and establishing a predetermined correspondence relationship between downlink resource block sets and uplink resource block sets before the actual transmission occurs. This allows the terminal equipment to determine the correct uplink resource without requiring additional indication fields in the scheduling information, thus simplifying the indication structure while maintaining transmission reliability through pre-established mapping rules
2Productivity
If the terminal equipment determines resource allocation bits based on active uplink bandwidth part subcarrier spacing, then the resource allocation can be optimized for current active configuration, but the terminal equipment may be unable to correctly determine resources when BWP switch is indicated
Solution Approach 1:
The patent applies preliminary action by pre-establishing correspondence relationships between downlink resource block sets and uplink resource block sets before BWP switching occurs. When BWP switch is indicated, the terminal equipment can use these pre-configured correspondence relationships to correctly determine the target uplink resource block sets, ensuring accurate resource allocation during bandwidth part switching without requiring complex real-time determination mechanisms
