Resource Indication Value Calculation for MTC UE Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for resource assignment in MTC UEs are inefficient, particularly when the number of resource blocks that a network side device can assign to a UE is limited, leading to increased signaling cost and power consumption due to the need for more bits to represent resource indication values.
Innovation Solution
A method that calculates a resource indication value (RIV) based on the maximum number of resource blocks a UE can schedule, reducing the number of bits required for resource indication and optimizing signaling cost, while also improving DCI format design to reduce missed detection probability and power consumption.

Engineering Contradiction Analysis
1Ease of manufacture
If the number of resource blocks that a network side device can assign to a UE is limited, then the UE cost can be reduced, but the number of bits required for resource indication increases
Solution Approach 1:
The patent changes the parameter N0 (maximum number of resource blocks a UE can schedule) from a fixed system-wide value to a UE-specific parameter. By allowing the network to configure different N0 values for different UEs based on their capabilities, the system can optimize resource indication efficiency for each UE while maintaining cost-effectiveness. This parameter change enables the resource indication to adapt to UE-specific constraints without requiring excessive bits for all UEs.
2Measurement precision
If more bits are used for resource indication, then resource assignment accuracy improves, but signaling cost increases
Solution Approach 1:
The patent introduces a configurable parameter N0 that determines the granularity and precision of resource indication. By adjusting N0 according to UE capabilities and service requirements, the system achieves optimal balance between resource assignment accuracy and signaling overhead. The resource indication value can precisely identify resource blocks when needed, while avoiding excessive precision that would increase signaling cost unnecessarily.
3Adaptability or versatility
If the resource indication uses more bits, then the resource assignment flexibility improves, but the power consumption increases
Solution Approach 1:
The patent makes the resource indication parameter N0 adaptable to different UE types and service scenarios. Low-cost UEs can be configured with smaller N0 values requiring fewer bits and lower power consumption, while capable UEs can use larger N0 values for greater flexibility. This parameter adaptation enables the system to achieve appropriate resource assignment flexibility for each UE without universally increasing power consumption across all devices.
