METHOD, APPARATUS AND SYSTEM FOR POWER LINE COMMUNICATION FOR INTERNET OF THINGS

Document Type and Number:

WIPO Patent Application WO/2022/183510

Kind Code:

A1

Abstract:

The present application relates to a method, apparatus and system for power line communication (PLC) for Internet of Things (IoT). The method comprises: a transmitting device receiving a first request from a receiving device, wherein the first request is used for requesting to execute a channel assessment for a first time window in a power line communication cycle; in response to the first request, the transmitting device transmitting, to the receiving device, a probe signal required for executing the channel assessment; the transmitting device receiving a modulation parameter from the receiving device, wherein the modulation parameter is determined by means of executing the channel assessment on the basis of the probe signal; and on the basis of the modulation parameter, the transmitting device performing, on the first time window, data transmission with the receiving device. According to the technical solution proposed herein, the rate performance of both broadband services and IoT services in a PLC broadband and PLC IoT fusion scenario, and the resource utilization efficiency can be greatly improved when there is limited complexity improvement.
