Claim:
1. Data signal transmitting method performed by a transmitting device in a wireless communication system wherein a main communication device transmits and receives data signal comprising a header and a payload to and from a plurality of devices by periodically using a transmission frame comprising a beacon signal transmitting interval, data signal transmitting interval allocated to each of devices, and data signal transmission resting interval, the data signal transmitting method comprising: determining a signal transmission speed of the payload based on a received signal strength indicator (RSSI) from a receiving device after estimating the RSSI based on a signal received by a transmitting device to which the data signal transmitting interval is allocated, before the data signal transmitting interval starts; determining a payload size that maximizes data throughput by using the determined signal transmission speed and channel occupancy characteristics of an interference signal in a communication channel of the wireless communication system; updating the determined signal transmission speed and the determined payload size to increase the data throughput by exploiting the estimated signal transmission and reception characteristics in the data signal transmitting interval; and transmitting the data signal to the receiving device by using the updated signal transmission speed and the updated payload size.
