摘要： A method for waking a device from a power save mode to an active mode includes: transmitting, by a first device, a magic packet through a predetermined channel to a second device, which operates in the power save mode by repeating a doze state and an awake state according to a predetermined period of time, for notifying the second device to switch to the active mode; and retransmitting the magic packet to the second device through the predetermined channel if a response to the magic packet has not been received from the second device and a predetermined time has not elapsed after transmitting the magic packet through the predetermined channel.

摘要： A wireless local area network (WLAN) communication method and apparatus are provided. The WLAN communication method includes allowing a receiving station to receive a multi input multi output (MIMO) frame, allowing the receiving station to determine whether the MIMO frame is erroneous and whether the MIMO frame is destined for the receiving station, allowing the receiving station to generate a single input single output (SISO) acknowledgement (ACK) frame if the MIMO frame is not erroneous and is destined for the receiving station, and allowing the receiving station to transmit the SISO ACK frame to a sending station that has transmitted the MIMO frame.
