Summary:The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. In addition, the present disclosure relates to a TCP-based transmission control method and apparatus which can reduce a delay time while improving a transmission rate in a communication system. A method for TCP-based transmission control in a communication system according to an embodiment of the present disclosure comprises the steps of: determining a maximum target transmission rate for TCP control using maximum congestion windows (CWNDs) estimated at predetermined times; determining a minimum target round trip time (RTT) for the TCP control using minimum RTTs estimated at the predetermined times; and updating at least one of a congestion window (CWND) and a receive window (RWND) in an RTT time slot, using the maximum target transmission rate and the minimum target RTT.
