Abstract
A data transmission apparatus in a communication system includes a reception unit configured to receive adjacent terminal information from a plurality of terminals through a new frequency band for transmission and reception of data between the terminals and one AP (access point); a verification unit configured to identify positions of the terminals within a service coverage of the AP through the adjacent terminal information, group the terminals into terminal groups through position-based grouping, and verify transmission possible times to the AP, in terminals included in the terminal groups; and a transmission unit configured to transmit the transmission possible times to the terminals included in the terminal groups through beacon frames in the AP, wherein, as the transmission possible times for the terminal groups, different time intervals are allocated in a beacon interval of the beacon frames.
