Device Property-Based Resource Allocation in Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in machine-to-machine (MTC) communication, there is a need to reduce signaling overhead and efficiently manage connections among devices with varying data characteristics, as existing methods do not account for the unique properties of each device's data, leading to inefficient authentication and resource allocation.
Innovation Solution
A communication method that classifies devices based on their properties, allocates resources to device groups with expected data information, and transmits resource allocation information, while performing authentication on devices with different data values, using a processor to manage pilot signals and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all devices use the same authentication and transmission scheme, then the system is simple to manage, but resource allocation efficiency deteriorates due to not considering device-specific data characteristics
Solution Approach 1:
The patent segments devices into different groups based on their data characteristics (e.g., MTC devices with small data packets vs. HTC devices with large data packets). Each group is assigned different authentication and transmission schemes, allowing the system to optimize resource allocation for each segment while maintaining manageable complexity through group-based management.
Solution Approach 2:
The patent applies local quality by tailoring authentication and transmission parameters to specific device groups rather than using uniform settings. For example, MTC devices use simplified authentication and transmission schemes optimized for small data packets, while HTC devices use more robust schemes for large data packets, thereby improving overall resource allocation efficiency.
2Productivity
If device-specific authentication and transmission schemes are implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The patent reduces system complexity by segmenting devices into distinct groups (MTC and HTC) with clearly defined characteristics. This segmentation allows the system to manage complexity at the group level rather than individually for each device, while still applying device-specific optimization within each group through standardized schemes.
Solution Approach 2:
The patent creates universal authentication and transmission schemes for each device group that can be applied to multiple devices within that group. This multi-functionality approach allows the system to handle diverse device requirements through a limited set of standardized schemes, balancing specificity with manageability.
3Quantity of substance
If uniform resource allocation is used for all devices, then signaling overhead is reduced, but transmission performance deteriorates due to ignoring device characteristics
Solution Approach 1:
The patent applies local quality by configuring transmission parameters (such as modulation schemes, coding rates, and resource block allocations) according to the specific data characteristics of each device group. MTC devices receive parameters optimized for small, frequent packets, while HTC devices receive parameters optimized for large, less frequent packets, thereby improving transmission performance without excessive signaling overhead.
Solution Approach 2:
The patent performs preliminary classification of devices into groups based on their data characteristics before resource allocation. This preliminary action allows the system to pre-determine appropriate transmission parameters for each group, reducing the need for extensive real-time signaling and negotiation while ensuring optimal transmission performance for each device type.

AI summary
Provided are a communication method based on device's property and an apparatus for allocating a resource by using the method. Devices are classified based on the device's property and a signal including information based on the resource allocation to the devices is transmitted to the devices. Data are received from a device through the allocated resource. Here, the devices transmitting pilot signals including device data values corresponding to preset expected reference data information transmit data through the allocated resource.
