Abstract
An operation method of a communication node including a physical (PHY) layer block and a controller , includes: receiving, at the PHY layer block, a signal transmitted from a counterpart communication node; transmitting, by the PHY layer block, a wakeup signal for waking up the controller to the controller; storing, by the PHY layer block, data included in the signal received from the counterpart communication node in a PHY layer buffer; and transmitting, by the PHY layer block, the data stored in the PHY layer buffer to the controller.

An operation method of a communication node including a physical (PHY) layer block and a controller, the method comprising:
- receiving, at the PHY layer block, a signal transmitted from a counterpart communication node;
- transmitting, by the PHY layer block, a wakeup signal for waking up the controller to the controller;
- storing, by the PHY layer block, data included in the signal received from the counterpart communication node in a PHY layer buffer;
- and
- transmitting, by the PHY layer block, the data stored in the PHY layer buffer to the controller.
An operation method of a communication node including a physical (PHY) layer block and a controller, the method comprising:
- receiving, at the controller, a wakeup signal for waking up the controller from the PHY layer block;
- performing, by the controller, a booting operation of an operating system (OS);
- and
- storing, by the controller, data received from the PHY layer block.
A physical (PHY) layer block of a communication node including the PHY layer block and a controller, comprising:
- a PHY layer interface part receiving a signal transmitted from a counterpart communication node;
- a PHY layer buffer storing data included in the received signal;
- and
- a PHY layer processor controlling the PHY layer interface part to transmit a wakeup signal for waking up the controller and controlling the PHY layer buffer to store the data included in the received signal in the PHY layer buffer,
- wherein the PHY layer processor controls the PHY layer buffer to transmit the data stored in the PHY layer buffer to the controller.
A controller of a communication node including a physical (PHY) layer block and the controller, comprising:
- a controller interface part receiving a wakeup signal for waking up the controller from the PHY layer block;
- a core performing an operating system (OS) booting operation according to the wakeup signal;
- a memory control logic controlling a storage part to store at least one of data for the OS booting operation and data transmitted from the PHY layer block;
- and
- the storage part storing the at least one of data for the OS booting operation and data transmitted from the PHY layer block according to control of the memory control logic.
