Abstract: A physical layer low power communication method and apparatus are provided. The physical layer low power communication method may include receiving a data packet from a transmitter, measuring a channel quality using a preamble and signal field information included in the data packet and determining whether recovery of the data packet is possible, calculating an error generation rate according to a determination result, and discarding the data packet and operating in a power save mode when the error generation rate is higher than a predetermined reference.
