Terminal Latency Reporting for Dynamic Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, managing communication resources based on varying processing latencies of terminals is challenging, as existing methods do not effectively account for differences in processing capabilities and power states of terminals, leading to inefficient resource allocation and potential delays in low-latency services like URLLC.
Innovation Solution
A communication resource management method where terminals report latency indication information to access network devices, allowing these devices to reserve and schedule resources such as HARQ resources and transmission resources based on the reported latency, ensuring optimal allocation according to the terminal's processing capabilities and current power state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication resources are managed using fixed allocation methods, then resource management is simple, but resource allocation efficiency deteriorates due to ignoring terminal processing capability differences
Solution Approach 1:
The patent implements dynamic resource management by allowing terminals to report their processing capability levels and current power states to the network device. The network device then dynamically adjusts communication resource allocation (such as HARQ timing and transmission resources) based on these reports, enabling the system to adapt to varying terminal capabilities and power conditions rather than using fixed allocation methods
Solution Approach 2:
The patent changes the parameter of resource allocation by introducing latency indication information that reflects terminal processing capabilities. The network device uses this information to adjust communication resource parameters such as timing relationships and resource grants, transforming the resource management approach from static to parameter-adaptive based on terminal state
2Loss of time
If resource allocation is optimized for low latency services, then service performance improves, but resource allocation complexity increases due to varying terminal capabilities
Solution Approach 1:
The patent applies local quality by tailoring resource allocation to individual terminal characteristics. Each terminal reports its specific processing capability level and power state, and the network device allocates resources locally optimized for that terminal's capabilities, rather than applying a uniform allocation scheme to all terminals
Solution Approach 2:
The patent uses preliminary action by having terminals report their processing capability levels and power states in advance before resource allocation decisions are made. This allows the network device to pre-optimize resource allocation parameters for low-latency services based on known terminal capabilities, reducing actual processing latency
3Use of energy by moving object
If terminals operate in low power state, then energy consumption decreases, but processing latency increases due to reduced processing capability
Solution Approach 1:
The patent implements dynamics by enabling terminals to dynamically report their current power state and processing capability level to the network device. The network device then dynamically adjusts communication resource allocation based on these reports, allowing terminals to operate in low-power states when possible while the network compensates with optimized resource allocation to maintain acceptable latency performance
Solution Approach 2:
The patent changes parameters by adjusting communication resource allocation parameters (such as HARQ timing and transmission opportunities) based on terminal power state reports. When terminals operate in low-power states with reduced processing capability, the network modifies resource parameters to accommodate the changed terminal state while managing the trade-off between power consumption and processing latency
