Multi-Channel Resource Scheduling with Unified DCI Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where Long Term Evolution (LTE) and New Radio (NR) coexist, existing methods face challenges in determining time and frequency domain resources and feedback information transmission for multiple physical channels using a single piece of DCI scheduling information, leading to interference and reduced system performance.
Innovation Solution
A method and system that allows a single piece of scheduling information to allocate transmission resources, such as time and frequency domains, and feedback information for multiple physical channels, reducing control channel interference and improving system performance.

1Object-generated harmful factors
If one piece of DCI scheduling information is used to schedule two or more PDSCH or PUSCH, then control channel interference is reduced, but it becomes difficult to determine time and frequency domain resources and feedback information transmission for multiple physical channels
Solution Approach 1:
The patent segments the scheduling information by introducing separate indication fields for different physical channels within the same DCI. Each physical channel (e.g., PDSCH, PUSCH) has its own time domain resource allocation field and frequency domain resource allocation field, allowing independent resource determination for each channel while maintaining unified scheduling through a single DCI message.
2Productivity
If one piece of DCI scheduling information schedules multiple physical channels, then scheduling efficiency is improved, but the device complexity for determining transmission resources increases
Solution Approach 1:
The patent implements a universal DCI structure that can simultaneously schedule multiple physical channels (PDSCH, PUSCH, and/or SPS release) using a single message. The DCI contains multiple sets of resource allocation fields that can be universally applied to different channel types, enabling one DCI to perform the function of multiple separate scheduling decisions while maintaining a standardized format.
