User Terminal Resource Block Assignment for Interlace Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation mobile communication systems, particularly in NR-U systems, there is a challenge in appropriately controlling the assignment of frequency-domain resources for uplink and downlink shared channels during interlace transmission, as existing methods do not account for interlace transmission scenarios, leading to inefficient resource allocation.
Innovation Solution
A user terminal receives specific information to determine sets of resource blocks within a given interval in a carrier band, allowing it to appropriately assign frequency-domain resources to uplink and downlink shared channels based on this information, using resource assignment details indicated in DCI formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interlace transmission is used for uplink or downlink shared channels, then frequency-domain resource assignment cannot be appropriately controlled
Solution Approach 1:
The patent segments the frequency-domain resources into multiple resource block sets, where each set contains resource blocks at given intervals. This segmentation allows independent control and assignment of each resource block set to different users or channels, enabling appropriate frequency-domain resource assignment control while maintaining interlace transmission capability. The resource block sets can be selectively assigned based on channel conditions, user requirements, and interference patterns.
2Productivity
If existing resource assignment methods are used, then resource allocation is inefficient for interlace transmission scenarios
Solution Approach 1:
The patent implements dynamic resource block set assignment where the base station can flexibly configure and assign different resource block sets to different users based on real-time channel conditions, traffic demands, and interference patterns. The resource block set configuration includes parameters such as starting resource block index and resource block quantity, which can be dynamically adjusted through RRC signaling and DCI formats. This dynamic approach maximizes resource allocation efficiency while fully supporting interlace transmission scenarios.

AI summary
A user terminal includes a receiving section that receives information to be used to determine a set of resource blocks in a given interval in a given band in a carrier, and a control section that determines, as a frequency-domain resource to be assigned to an uplink shared channel or a downlink shared channel, the set determined based on the information. Accordingly, it is possible to appropriately control assignment of frequency-domain resources to an uplink shared channel or downlink shared channel transmitted by interlace transmission.
