Method and apparatus for transmitting and receiving in communication system

A base station (BS) in a communication system, the BS comprising:

• a transceiver configured to transmit and receive data;
• and
• a controller configured to control the transceiver,
• wherein the controller is further configured to:
• transmit, to a plurality of stations (STAs) included in a group, the data including information indicating a quantity of STAs included in the group and a quantity of STAs included in other groups, based on a time division duplexing (TDD) scheme;
• receive response signals from each of the plurality of STAs through a resource, wherein the resource is allocated sequentially for each STA based on the information indicating the quantity of STAs included in the group and the quantity of STAs included in the other groups,
• in case that a negative acknowledgement (NACK) signal is received from a STA in the group, retransmit the data to the plurality of STAs included in the group, wherein the STA which transmitted the NACK signal is located within a predetermined distance from the BS, and
• in case that a NACK signal is received from a STA in the group, retransmit the data only to the STA, wherein the STA which transmitted the NACK signal is located outside the predetermined distance from the BS.
