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 after receiving forward information commanding a reverse data rate change on a forward channel from a base station, comprising the steps of:
- increasing the reverse data rate to be equal to or lower than a maximum data rate if the forward information commands a reverse data rate increase; and
determining whether the increased data rate for a next frame is possible and transmitting the determination result to the base station.

Abstract
A reverse transmission controlling method in a mobile communication system. After receiving forward information commanding a reverse data rate change on a forward channel from a base station, a mobile station increases its reverse data rate to a data rate equal to or lower than a maximum data rate if the forward information commands a reverse data rate increase, determines whether the increased data rate can be further increased for the next frame, and transmits the determination result with information representing the increased data rate to the base station.

5. A method of controlling a reverse data rate in a mobile station after receiving forward information commanding a reverse data rate change on a forward channel from a base station, comprising the steps of:
-
increasing the reverse data rate to be equal to or lower than a maximum data rate based on information indicating whether a data rate increase is available that is determined at a previous frame transmission if the forward information commands a conditional reverse data rate increase; and
determining whether the increased data rate for a next frame is possible and transmitting the determination result to the base station. - View Dependent Claims (6, 7, 8)

9. A method of controlling a reverse data rate in a mobile station after receiving forward information commanding a reverse data rate change on a forward channel from a base station, comprising the steps of:
-
decreasing the reverse data rate to be equal to or higher than a minimum data rate based on information indicating whether a data rate increase is available that is determined at a previous frame transmission if the forward information commands a conditional data rate decrease; and
determining whether the decreased data rate for a next frame is possible and transmitting the determination result to the base station. - View Dependent Claims (10, 11, 12, 14, 15, 16, 17, 19)

13. A method of controlling a reverse data rate in a mobile station after receiving forward information commanding a reverse data rate change on a forward channel from a base station, comprising the steps of:
-
maintaining the reverse data rate if the forward information commands an unconditional data rate maintenance; and
determining whether the maintained reverse data rate for a next frame is possible and transmitting the determination result to the base station.

18. A method of controlling the data rate of a mobile station in a base station after receiving reverse information indicating whether a reverse data rate increase is available for a next reverse frame from the mobile station, comprising the steps of:
determining an extended reverse activity bit (RAB) based on the received reverse information and a current capacity of a reverse link and transmitting the extended RAB to the mobile station.

20. A mobile station device for controlling a reverse data rate after receiving forward information commanding a reverse data rate change on a forward channel from a base station, comprising:
-
a apparatus for increasing the reverse data rate to equal to or lower than a maximum data rate if the forward information commands a reverse data rate increase, increasing the reverse data rate to equal to or lower than the maximum data rate based on information determined at a previous frame transmission indicating whether a data rate increase is available if the forward information commands a conditional reverse data rate increase, decreasing the reverse data rate to equal to or higher than a minimum data rate based on the information determined at the previous frame transmission indicating whether a data rate increase is available if the forward information commands a conditional reverse data rate decrease, maintaining the reverse data rate if the forward information commands an unconditional data rate maintenance, and determining whether the changed or maintained reverse data rate can be increased for a next frame; and
a apparatus for transmitting the determination result to the base station.
