Abstract: PURPOSE: An apparatus and a method for transmitting and receiving data in a communication system are provided to construct a frame in a new frequency band for transmitting and receiving data at high speeds and steadily. CONSTITUTION: A receiving unit (210) receives a beacon frame corresponding to a beacon period, which is transmitted from an access point (AP) using a new frequency band for transmitting/receiving between a plurality of terminals and the AP. An estimating unit (220) estimates a carrier frequency error in the physical layer (PHY) of the new frequency band, and using the estimated carrier frequency error, estimates a time when the beacon frame is received. A control unit (230) corresponds to the time received by the beacon frame to change modes of the terminals from a sleep mode into a receiving standby mode.
