BWP Resource Allocation Field Alignment for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face resource shortages and struggle to support high-speed data services, increased user connections, low latency, and energy efficiency, particularly in determining resource allocation for bandwidth parts (BWP) during switching, leading to ambiguity in interpreting scheduling DCI.
Innovation Solution
A method for determining resource allocation to a BWP by receiving resource allocation fields from the network, where the processor configures resource allocation based on predefined values and index information, using a predefined starting point and random functions to manage resource block groups, ensuring efficient resource allocation and BWP switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource allocation fields are configured for multiple BWPs with different sizes, then resource allocation flexibility is improved, but ambiguity in interpreting scheduling DCI increases during BWP switching
Solution Approach 1:
The patent implements dynamic BWP switching where the terminal can switch between multiple BWPs with different sizes based on scheduling needs. The resource allocation fields are dynamically configured for each BWP, allowing the system to adapt resource allocation flexibility to varying traffic requirements while maintaining clear interpretation rules during switching transitions.
Solution Approach 2:
The patent resolves DCI interpretation ambiguity by pre-defining the starting point for resource allocation in advance. When BWP switching occurs, the terminal uses the pre-configured starting point information to correctly interpret the resource allocation field without ambiguity, ensuring that the preliminary configuration prevents misinterpretation during dynamic switching.
2Loss of information
If resource allocation is determined based on predefined starting points, then DCI interpretation ambiguity is reduced, but resource allocation precision may be compromised
Solution Approach 1:
The patent pre-configures starting points for resource allocation in the BWP configuration information. This preliminary action ensures that when BWP switching occurs, the terminal has advance knowledge of where resource allocation should begin, eliminating interpretation ambiguity while maintaining precision through the structured pre-configuration approach.
Solution Approach 2:
The patent applies different starting point configurations for different BWPs based on their specific characteristics. Each BWP can have its own predefined starting point tailored to its size and resource requirements, ensuring that the local quality of resource allocation is optimized for each specific BWP while maintaining overall system consistency.

AI summary
Disclosed herein is a method for determining a resource area to be allocated to a bandwidth part (BWP) in a wireless communication system. More specifically, the method performed by a terminal includes: receiving, from a network, a first resource allocation field associated with a resource allocation group (RBG) size for a first BWP and a second resource allocation field associated with an RBG size for a second BWP, on the first BWP; and when the size of the first resource allocation field is greater than the size of the second resource allocation field, determining a resource area to be allocated to the second BWP, based on a value of the first resource allocation field, which corresponds to the size of the second BWP, starting from a predefined point.
