摘要： A method for performing reverse link power control by determining the state of a reverse link data rate control bit in a mobile station according to variable thresholds that are set according to the size of a data packet to be transmitted. By considering the size of the data packet to be transmitted when setting the thresholds used to determine the state of the rate control bit, the increased sensitivity at higher data packet sizes of system stability to an incorrect determination of the state of the rate control bit may be accommodated. Furthermore, when a mobile station is located within a soft handoff area, the number of base stations transmitting rate control bits to the mobile station is considered when setting the variable thresholds.

摘要： 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.
