Data Scheduling Method for Simultaneous Multi-Unit Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE and 5G systems, existing dynamic scheduling methods are inadequate for handling services with large amounts of traffic, as they can only instruct data bearing on a single time domain unit at a time, failing to efficiently manage multiple target time domain units simultaneously.
Innovation Solution
A data scheduling method and apparatus where a base station transmits a rule for determining target location information and transmission modes to a terminal, allowing simultaneous data bearing on multiple target time domain units through a single scheduling signaling, using configuration or scheduling signaling, such as RRC signaling, to optimize dynamic scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing dynamic scheduling methods are used to instruct data bearing on a single time domain unit, then the scheduling method is simple to implement, but it cannot efficiently manage multiple target time domain units simultaneously for services with large amounts of traffic
Solution Approach 1:
The patent segments the scheduling process by introducing separate indication information for each target time domain unit. The base station transmits scheduling signaling that includes specific indication information (such as time domain resource assignment, frequency domain resource assignment, and modulation and coding scheme) for each target time domain unit, allowing independent control and optimization of data bearing on multiple units simultaneously.
Solution Approach 2:
The patent extends the scheduling dimension from single time domain unit to multiple time domain units by adding time domain unit identification as an additional dimension. The scheduling signaling now includes indication information that specifies which time domain units should be used for data bearing, transforming the scheduling approach from one-dimensional (single unit) to multi-dimensional (multiple units with specific identifiers).
2Quantity of substance
If multiple target time domain units are scheduled simultaneously through single scheduling signaling, then resource occupation is reduced, but the signaling complexity and configuration overhead increase
Solution Approach 1:
The patent merges multiple scheduling operations into a single scheduling signaling transmission. Instead of sending separate scheduling signals for each target time domain unit, the base station combines the scheduling information for multiple units into one signaling message, including indication information for each unit's time domain resources, frequency domain resources, and transmission parameters.
Solution Approach 2:
The scheduling signaling is designed with multi-functionality to handle different scenarios. It can indicate one or multiple target time domain units, support both continuous and non-continuous time domain unit patterns, and accommodate various service types (e.g., eMBB, URLLC) through configurable indication information structures.
3Adaptability or versatility
If configuration signaling is used to transmit rules for determining target location information, then the scheduling flexibility is improved, but the signaling overhead increases
Solution Approach 1:
The patent uses configuration signaling to pre-configure rules and parameters for determining target location information before actual data transmission. The base station transmits configuration information (such as time domain resource patterns, frequency domain resource allocations, and transmission mode settings) in advance, allowing the terminal to efficiently determine target time domain units without requiring detailed real-time signaling for each transmission.

AI summary
A data scheduling method includes: transmitting to a terminal a determination rule for determining target location information corresponding to each of a plurality of target time domain units, the plurality of target time domain units being a plurality of time domain units for performing data bearing according to scheduling signaling. As such, in the dynamic scheduling of a terminal by a base station, an objective of simultaneously scheduling a plurality of target time domain units through one scheduling signaling to perform data bearing can be realized.
