Internet of Things base station and resource arrangement method thereof

Abstract

The invention discloses an Internet of Things base station and a resource arrangement method thereof. The Internet of Things base station arranges a sequence for each of a plurality of candidate resources of a downlink shared channel for a plurality of user devices, a resource waste amount between every two adjacent user devices is calculated, and each resource waste amount is calculated based ona basic delay, an end position of downlink control information of the two corresponding user devices in a downlink control channel, an additional delay of each of the two corresponding user devices, and a resource demand amount corresponding to the former one of the two corresponding user devices. Each candidate resource arrangement sequence corresponds to a total resource waste amount. And the Internet of Things base station selects the candidate resource arrangement sequence corresponding to the minimum total resource waste amount as a selected resource arrangement sequence.

Description

technical field [0001] The invention relates to a base station of the Internet of Things and a resource arrangement method thereof. More specifically, the present invention relates to an IoT base station and a method for arranging downlink resources for multiple user devices. Background technique [0002] Many Internet of Things communication standards have special specifications on how to arrange downlink resources of multiple user devices, for example: Narrow Band Internet of Things (Narrow Band Internet of Things) formulated by The 3rd Generation Partnership Project Agreement (3GPP) Things; NB-IoT) standard, Massive Machine-Type Communications (Massive Machine-Type Communications; Massive MTC) standard in the fifth generation mobile communication system, etc. figure 1 A structure of a downlink processing cycle 10 of a common IoT communication standard is depicted, which includes a downlink control channel 12 for transmitting control signals and a downlink shared channel ...

AI Technical Summary

Problems solved by technology

[0006] Since the known Internet of Things base station arranges transmission resources for user devices on the downlink shared channel 14 based on the first-come-first-served principle, the additional delay limited by each user device must be selected from a predetermined group and the user device is scheduled for transmission Resources cannot overlap, and the result of resource arrangement in conventional technologies often causes many resource gaps in the downlink shared channel 14, and the result of resource arrangement can easily exceed the current downlink processing cycle 10 (for example: figure 1 The transmission resource D 4 Exceeding the downlink processing cycle 10), resulting in serious waste of resources
