Document Type and Number:
WIPO Patent Application WO/2021/204023
Kind Code:
A1
Abstract:
Disclosed are a method, apparatus and system for channel estimation in a power-line network. A specific channel estimation method comprises: a device receives channel estimation request messages respectively sent by a plurality of other devices; then the device broadcasts or multicasts a channel estimation reply message to the plurality of other devices, to instruct the plurality of other devices to perform channel estimation. Optionally, the device can also broadcast or multicast a probe message for the plurality of other devices to perform channel estimation. Channel estimation of a plurality of channels is completed by sending a single channel estimation reply message, and the channel estimation method can reduce the number of messages that need to be exchanged for channel estimation and shorten the time required for channel estimation.
