Claim:
1. A data reception apparatus in a communication system, comprising: a generation unit configured to generate terminal information in a frequency band for transmission and reception of data between a terminal and an AP (access point), the terminal information including information on a period between transmissions; a transmission unit configured to transmit the terminal information to the AP; a reception unit configured to receive beacon frames from the AP through the frequency band, and receive terminal access information from the AP, the terminal access information corresponding to the terminal information; and a verification unit configured to verify access timing to the AP based on the beacon frames by using the terminal access information and the period between transmissions, wherein the transmission unit accesses the AP at the access timing and transmits first and second data frames to the AP, wherein the terminal access information includes information on an offset, the offset corresponding to a transmission starting time of the first data frame, as standby time information to until the terminal transmits the first data frame from a reference beacon frame among the beacon frames, wherein a transmission starting time of the second data frame occurs the period between transmissions after the transmission of the first data frame, and wherein the period between transmissions is a period of time different than a beacon interval between the beacon frames.
