Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) systems, the uniform configuration of frequency domain offsets for Bandwidth Parts (BWP) limits the utilization of larger bandwidths, resulting in reduced frequency selective gain and transmission performance.
Innovation Solution
Configuring different frequency domain offset sets for various BWPs, allowing for maximum frequency hopping offset within each BWP's bandwidth, by sending specific configuration information from a network device to a terminal, which determines the offsets for each BWP.

Engineering Contradiction Analysis
1Ease of manufacture
If the frequency domain offset is uniformly configured according to the BWP with the minimum bandwidth, then the configuration is simple and easy to implement, but the larger bandwidth of the BWP with larger bandwidth cannot be fully utilized, limiting the frequency selective gain and reducing transmission performance
Solution Approach 1:
The patent applies local quality by configuring different frequency domain offset sets for different BWPs based on their individual bandwidth characteristics. Each BWP has its own tailored frequency domain offset set that matches its specific bandwidth, allowing optimal frequency hopping performance for each local configuration rather than applying a uniform offset across all BWPs.
Solution Approach 2:
The patent changes the parameter of frequency domain offset from a uniform fixed value to multiple configurable offset sets with different values. The network device can select and configure appropriate offset sets based on the specific BWP bandwidth, transforming the system from a single-parameter configuration to a multi-parameter adaptive configuration that optimizes transmission performance.
2Device complexity
If the frequency domain offset is uniformly configured according to the BWP with the minimum bandwidth, then the configuration process is simplified, but the frequency selective gain is limited due to inability to realize frequency hopping with larger amplitude
Solution Approach 1:
The patent introduces dynamics by making the frequency domain offset configuration adaptive to different BWP scenarios. Instead of a static uniform offset, the system dynamically selects appropriate frequency domain offset sets based on the active BWP's bandwidth characteristics, enabling the frequency hopping amplitude to adapt to the available bandwidth and maximize frequency selective gain.
Solution Approach 2:
The patent segments the frequency domain offset configuration into multiple independent offset sets, each optimized for specific BWP bandwidth ranges. This segmentation allows each offset set to be independently configured and selected based on the active BWP, enabling finer-grained optimization of frequency hopping parameters for different bandwidth scenarios.
