Apparatus and method for transmitting/receiving data in communication system

A data transmitting method in a communication system, comprising:

• receiving terminal information from a plurality of terminals through a frequency band for transmitting and receiving data between the plurality of terminals and one AP (access point);
• verifying the terminal information, grouping the terminals into terminal groups based on the terminal information, and verifying virtual APs which respectively correspond to the terminal groups, in the AP;
• and
• transmitting beacon frames in the virtual APs, to the terminals included in the terminal groups,
• wherein the beacon frames include beacon interval information, beacon duration information, beacon offset information, and terminal group information,
• wherein the AP is a single physical AP including the virtual APs and performing functions of the virtual APs,
• wherein the virtual APs respectively administer corresponding respective terminal groups, and respectively transmit corresponding respective beacon frames to the corresponding respective terminal groups, and
• wherein the virtual APs use the frequency band by dividing the frequency band being used by the AP in a time division scheme.

A data reception apparatus in a communication system, comprising:

• a generation unit configured to generate terminal information in a new frequency band for transmitting and receiving data between a plurality of terminals and one AP (access point);
• a transmission unit configured to transmit the terminal information to the AP;
• and
• a reception unit configured to receive beacon frames from a virtual AP of a terminal group corresponding to the terminal information in the AP,
• wherein the terminals are grouped into terminal groups based on the terminal information,
• wherein the AP is a single physical AP including the virtual APs and performing functions of the virtual APs,
• wherein the virtual APs respectively administer corresponding respective terminal groups, and respectively transmit corresponding respective beacon frames to the corresponding respective terminal groups,
• wherein the virtual APs use the frequency band by dividing the frequency band being used by the AP in a time division scheme,
• wherein terminals included in the terminal groups are connected to the AP, by respectively receiving the corresponding respective beacon frames from corresponding respective virtual APs, and
• wherein the beacon frames include beacon interval information, beacon duration information, beacon offset information, and terminal group information.
