Terminal Scheduling Type Indication for Service Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, terminals face challenges in distinguishing different scheduling types for effective data transmission, particularly in supporting multiple service types with varying requirements such as eMBB, URLLC, and mMTC, which demands efficient resource scheduling modes.
Innovation Solution
The terminal receives scheduling signaling from the base station, which includes scheduling type indication information, and uses pre-stored configuration information to determine the appropriate scheduling type, such as slot-based or symbol-based scheduling, to perform resource scheduling accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal uses traditional scheduling modes without explicit scheduling type indication, then the device complexity is reduced, but the terminal cannot effectively distinguish different scheduling types for multiplexing multiple service types
Solution Approach 1:
The patent introduces scheduling type indication information as an intermediary element carried in the scheduling signaling. This intermediary allows the terminal to distinguish between different scheduling types (e.g., slot-based, symbol-based) without fundamentally changing the core scheduling architecture. The indication information acts as a mediator between the base station's scheduling decisions and the terminal's resource allocation actions, enabling multiplexing of multiple service types while maintaining relatively simple device structure.
2Measurement precision
If the base station transmits detailed scheduling configuration information for each service type, then the terminal can accurately determine scheduling types, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the essential scheduling type indication information from the full scheduling configuration and transmits it separately in the scheduling signaling. Instead of transmitting complete configuration details for each service type, the base station extracts and sends just the scheduling type indication (e.g., through DCI formatting or specific fields), which is sufficient for the terminal to identify the scheduling type. This extraction approach reduces signaling overhead while maintaining identification accuracy.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the terminal with scheduling type indication mechanisms before actual data transmission. The terminal is pre-programmed with the understanding of what scheduling type indication information to expect and how to interpret it, so that during actual operation, no additional detailed configuration is needed. This preliminary setup allows accurate scheduling type determination with minimal real-time signaling.

AI summary
The present disclosure relates to a data transmission method, a device, and a computer readable storage medium, and relates to the field of communication technologies. The method includes: receiving scheduling signaling sent by a base station, wherein the scheduling signaling carries scheduling type indication information; determining a scheduling type corresponding to the scheduling type indication information based on the scheduling type indication information and pre-stored configuration information, wherein the configuration information includes a correspondence between a plurality of pieces of scheduling type indication information and a plurality of scheduling types; and performing resource scheduling based on the scheduling type to achieve data transmission. In the embodiment of the present disclosure, when the terminal supports multiple types of scheduling modes, the distinction between scheduling types is implemented.
