Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE resource allocation methods face challenges in ultra-wideband communications, leading to increased information requirements and potential throughput drops in next-generation radio communication systems like 5G.
Innovation Solution
A user terminal and radio communication method that allocates resources by using relative coordinates and amounts with respect to a reference resource, reducing the number of control information bits needed, thereby maintaining throughput even in wideband communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing LTE resource allocation methods are applied to ultra-wideband communications, then resource allocation can be performed, but the amount of control information increases and throughput may drop
Solution Approach 1:
The patent segments the resource allocation information into two parts: (1) common information shared across multiple users, and (2) user-specific differential information. By segmenting the control information this way, the patent reduces the number of bits needed for resource allocation in ultra-wideband communications while maintaining allocation accuracy.
Solution Approach 2:
The patent changes the parameter representation method by using relative resource allocation offsets instead of absolute resource indices. This parameter transformation reduces the number of bits required to represent resource allocations in wideband scenarios, directly addressing the control information overhead problem.
2Manufacturing precision
If resource allocation information is increased to support ultra-wideband communications, then resource allocation accuracy improves, but control overhead increases
Solution Approach 1:
The patent divides resource allocation information into segmented components that can be efficiently encoded. By segmenting the allocation data into common and differential parts, the patent achieves precise resource allocation without requiring a complete increase in control information structure complexity.
Solution Approach 2:
The patent applies partial action by transmitting only the necessary differential information for each user rather than complete resource allocation information. This approach maintains allocation accuracy for the specific resources needed while avoiding excessive control overhead for the entire ultra-wideband spectrum.

AI summary
The present invention is designed so that that resources are allocated adequately even in broadband communication. A user terminal, according to one aspect of the present invention, has a receiving section that receives specifying information for specifying a frequency offset of a radio resource relative to a reference resource and/or an allocation resource amount of the radio resource, and a control section that determines allocation of the radio resource based on the specifying information.
