Uplink Cancellation Signaling With Adaptive Bit Granularity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information transmission methods in mobile communication systems, such as 5G, face inflexibility in uplink cancellation indication parameters, leading to waste of information bits or incomplete indication due to fixed configurations that do not account for varying service requirements.
Innovation Solution
The method involves transmitting uplink cancellation indications with first and second indication information, where the first parameter of the second indication information is determined based on the payload size and bit quantity of the uplink cancellation indication, including bit quantity and indication granularity, to enhance flexibility and reduce waste or incomplete indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed parameter configurations are used for uplink cancellation indication, then the indication information structure is simple, but information bits are wasted or indication is incomplete
Solution Approach 1:
The patent applies dynamics by making the parameter configuration of indication information adjustable rather than fixed. The network side device dynamically determines parameters such as bit quantity and indication granularity based on actual service requirements and resource conditions, allowing the indication information structure to adapt to different scenarios and avoid information waste.
Solution Approach 2:
The patent changes parameters of the indication information dynamically. Specifically, the bit quantity and indication granularity are adjusted based on the payload size and service requirements, transforming the fixed parameter configuration into a variable one that optimizes information transmission efficiency.
2Productivity
If dynamic multiplexing is used for eMBB and URLLC services, then resource utilization is improved, but URLLC transmission reliability may be compromised
Solution Approach 1:
The patent implements feedback mechanisms where the network side device monitors service requirements and resource conditions in real-time. Based on this feedback, the device dynamically adjusts indication information parameters to ensure URLLC transmissions are reliably scheduled while optimizing overall resource utilization for both eMBB and URLLC services.
