Abstract
A method of determining a packet data rate in a mobile communication system is provided. The method includes steps of estimating a channel reception status value after a predetermined time corresponding to a predetermined window size, by assigning a different weight factor to at least one channel reception status of an earlier time and to a channel reception status of a present time; determining a remainder value for adjusting a channel reception sensitivity value according to a decoding status of received packet data, by incrementing the remainder value when the received data packet is successfully decoded and otherwise decrementing the remainder value, i.e., when decoding is unsuccessful; calculating a threshold value for determining a packet data rate by applying the remainder value to the estimated channel reception status value; and determining a highest packet data rate among a set of values falling below a rate corresponding to the calculated threshold value. The threshold value is applied to the channel reception status value estimated for each predetermined window size.
