Resource Allocation for Passive IoT Tag Inventory Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In passive internet of things (PIOT) or ultra-low power consumption communication scenarios, the method for obtaining related information of a large quantity of tags is inefficient and needs improvement.
Innovation Solution
A resource allocation method where a network side device sends first information to a target device, allocating or configuring resources for the target device to report second information, based on a preset rule that includes selecting different resources for different service types, device types, or moments.

If inventory method is used to obtain tag information, then all tags can be queried, but the efficiency is low when there is a large quantity of tags
Solution Approach 1:
The patent segments the large population of tags into multiple groups, with each group assigned to a specific group ID. The network side device performs inventory operations on each group separately rather than attempting to inventory all tags simultaneously, thereby improving efficiency when dealing with large quantities of tags
Solution Approach 2:
The patent implements preliminary grouping of tags before the inventory operation. The network side device sends grouping configuration information to tags in advance, organizing them into distinct groups with unique group IDs. This preliminary organization enables more efficient subsequent inventory operations compared to querying all tags without pre-grouping

AI summary
This application discloses a resource allocation method which includes: The network side device sends first information to a target device, where the target device includes at least one of a backscatter communication device and an ultra-low power device, the ultra-low power device is a terminal device whose power consumption is less than a preset threshold, the first information is used to allocate a target resource to the target device, the target resource is selected by the network side device from a preset resource set according to a preset rule, or the first information is used to configure the preset resource set for the target device, so that the target device selects the target resource from the preset resource set according to the preset rule, and the target resource is used by the target device to report second information to the network side device.
