Terminal Channel Priority Logic for Overlapping Radio Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems struggle to appropriately determine the priority of channels with overlapping resource allocations for services with different requirements, such as eMBB and URLLC, due to issues with determining channel priority based on reception order, CORESET configuration, and transmission beamforming, leading to potential delays and miscommunication.
Innovation Solution
A terminal and communication method that determines channel priority based on priority indications within DCIs and considers overlapping resource areas, using either priority indications or reception order, depending on the configuration of CORESETs and beamforming, to ensure appropriate radio communication processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If channel priority is determined based on reception order of control information, then the determination method is simple, but it causes delays and miscommunication when channels with different service requirements overlap
Solution Approach 1:
The patent changes the determination parameter from reception order to priority indications embedded in DCIs. When control information portions indicate different priorities, the terminal determines channel priority based on these priority indications rather than reception timing, thereby resolving the contradiction between simple determination and timely communication for overlapping channels with different service requirements.
2Reliability
If channel priority is determined based on CORESET configuration, then the determination is systematic, but it fails when control information portions are mapped to different CORESETs with different beams
Solution Approach 1:
The patent introduces priority indications in DCIs as an intermediary mechanism that works independently of CORESET configuration and beamforming. This intermediary allows the terminal to determine channel priority without being affected by whether control information portions are mapped to different CORESETs or beams, thus resolving the contradiction between systematic determination and adaptability to diverse beamforming configurations.
3Ease of operation
If the terminal uses a single priority determination method for all cases, then the method is easy to implement, but it cannot accommodate different service requirements (eMBB vs URLLC) with overlapping resources
Solution Approach 1:
The patent implements a dynamic priority determination mechanism where the terminal selects between reception-order-based determination and priority-indication-based determination according to the specific service requirements and resource allocation scenarios. This dynamic approach allows the system to adapt to different service types (eMBB, URLLC) while maintaining implementation feasibility, resolving the contradiction between ease of operation and service adaptability.

AI summary
The objective of the present invention is to implement appropriate radio communication processing in accordance with required criteria. This terminal is provided with: a control circuit which determines a method for determining a priority level of a first channel and a second channel having mutually overlapping resource allocations in the time domain, on the basis of a parameter relating to control information indicating the allocations of the first channel and the second channel respectively; and a communication circuit for transmitting or receiving a signal to or from at least one of the first channel and the second channel, on the basis of the priority level.
