Method of controlling reverse transmission in a mobile communication system
First Claim
1. A method of controlling a reverse data rate in a mobile station receiving a forward information commanding an increase or decrease of the reverse data rate received on a forward channel from a base station, comprising the steps of:
- determining whether a previous rate increase available information transmitted to the base station on a reverse channel before reception of the forward information indicates that the reverse data rate increase is available, if the forward information commands the reverse data rate increase; and
increasing the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmitting reverse data at the increased reverse data rate.

Abstract
A reverse transmission controlling method in a mobile communication system, after receiving forward information, commanding the increase or decrease of the reverse data rate received on a forward control channel from a base station, a mobile station determines whether the previous rate increase available information transmitted to the base station on a reverse control channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase. The mobile station increases the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmits reverse data at the increased reverse data rate.

14. A method of controlling a reverse data rate in a base station after receiving rate increase available information from a mobile station, comprising the steps of:
-
checking a reverse data rate increase available information received from the mobile station and a capacity of a reverse link; and determining a forward information commanding increase or decrease of the reverse data rate based on the checked result and transmitting the determined forward information to the mobile station. - View Dependent Claims (15, 16, 17, 18)

19. An apparatus for controlling a reverse data rate in a mobile station receiving forward information commanding an increase or decrease of the reverse data rate received on a forward channel from a base station, comprising:
-
a determining device for determining whether a previous rate increase available information transmitted to the base station on a reverse channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase; and an increasing device for increasing the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmitting reverse data at the increased reverse data rate.

-
a checking device for checking a reverse data rate increase available information received from the mobile station and a capacity of a reverse link; and a determining device for determining the forward information representing increase or decrease of the reverse data rate of the mobile station based on the determined result and transmitting the determined forward information to the mobile station.
