Terminal Device Random Access Scheduling via Processing Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, terminal devices with relaxed processing capabilities face challenges in sending random access messages due to insufficient time for PDSCH or PUSCH processing, as network devices schedule all devices based on unrelaxed processing capabilities.
Innovation Solution
The proposed solution involves determining resources for random access messages based on the physical layer channel/signal processing capability of terminal devices, allowing network devices to calculate processing time delays and schedule subsequent messages accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the network device schedules all terminal devices based on unrelaxed processing capability, then the scheduling accuracy for terminal devices with relaxed processing capability deteriorates, but the device complexity increases due to needing to manage multiple processing capability types
Solution Approach 1:
The patent changes the scheduling parameter from a fixed unrelaxed processing capability to a variable parameter that adapts to the terminal device's actual processing capability. The network device determines whether to apply relaxed or unrelaxed processing capability based on the terminal device type, achieving accurate scheduling without complex multi-capability management by using parameter adaptation rather than structural complexity
Solution Approach 2:
The terminal device with relaxed processing capability autonomously determines its own processing capability type and selects appropriate resources without requiring complex network device intervention. The network device simply schedules based on the terminal device's self-declared capability, reducing scheduling complexity while maintaining accuracy
2Duration of action of moving object
If the network device uses unrelaxed processing capability for scheduling, then the processing time for terminal devices with relaxed processing capability is insufficient, but the resource utilization efficiency deteriorates due to unnecessary rescheduling
Solution Approach 1:
The terminal device with relaxed processing capability pre-determines its processing time requirement before resource allocation. The network device schedules resources in advance based on this predetermined relaxed processing time, ensuring sufficient processing time while avoiding the need for rescheduling, thus maintaining high resource utilization efficiency
Solution Approach 2:
The patent changes the processing time parameter from the fixed unrelaxed value to a variable that adapts to the terminal device type. By using relaxed processing time for terminal devices with relaxed capability, the system ensures sufficient processing duration while maintaining efficient resource utilization through accurate parameter matching

AI summary
A terminal device scheduling method is performed by a terminal device, and includes: determining a resource corresponding to a random access message based on a physical layer channel or signal processing capability of the terminal device; and sending the random access message through the resource to a network device, to enable the network device to determine a random access message processing time delay of the terminal device based on the resource corresponding to the random access message and to schedule a transmission of a subsequent random access message of the terminal device.
