User class provisioning for R-PDCH via a single common rate control sub-channel
First Claim
1. A method of user class provisioning for a reverse traffic channel in a wireless communication system including a plurality of mobile stations, comprising:
- defining at least two classes of users;
assigning a first user to a first class by transmitting a first predetermined value to the first user'"'"'s mobile station;
assigning a second user to a second class by transmitting a second, different predetermined value to the second user'"'"'s mobile station; and
managing reverse link traffic by issuing per-sector common rate control (CRC) commands, the first user'"'"'s mobile station responding differently to said CRC commands than the second user'"'"'s mobile station in response to said predetermined values.

Abstract
Users in a wireless communication system are provisioned into QoS-based classes and rate controlled using a single, per-sector common rate control (CRC) sub-channel. In one or more embodiments, different mobile stations are configured to respond differently to the same CRC commands by provisioning them with different Traffic-to-Pilot Ratio (TPR) tables and/or with different TPR step size adjustment tables. That is, the network can define different classes or groups of mobile stations by sending class or group-specific TPR-related values to the mobile stations belonging to a specific class or group. With this method, the mobile stations in one group can achieve different reverse link data rates, or make more aggressive data rate changes, than those in another group, even though both groups receive the same rate control commands.

7. A method of selective group rate control for a reverse traffic channel in a wireless communication system including a plurality of mobile stations, comprising:
-
transmitting to a select subset of said plurality of mobile stations a predetermined value; and
issuing per-sector common rate control (CRC) commands operative to alter the data rate of said subset of mobile stations differently than the data rate of others of said plurality of mobile stations in response to said predetermined value. - View Dependent Claims (8, 9)

10. A wireless communication system, comprising:
-
a plurality of mobile stations, each including a TPR table and a TPR step size table, and each operative to transmit packet data on a reverse packet data channel (R-PDCH) at a rate dynamically determined by a reverse pilot channel (R-PICH) power and values in said TPR and TPR step size tables; and
at least one base station issuing per-sector common rate control (CRC) commands in at least one sector to control the the R-PDCH data rate of one or more of the mobile stations; and
said base station configured to effect different reverse link rate control command response behaviors between different ones of the mobile stations responding to the CRC commands by altering at least one of said TPR table and TPR step size table values. - View Dependent Claims (11)

12. A method of determining a data rate for transmitting data on a reverse traffic channel of a mobile station assigned to a user class, comprising:
-
receiving values for at least one of a TPR step size table and TPR table, said values configured to the user class to which the mobile station is provisioned;
receiving per-sector common rate control (CRC) commands from at least one sector in the active set;
calculating a combined CRC command;
in response to the combined CRC command;
accessing a value in said TPR step size table and calculating a maximum TPR;
in response to the calculated maximum TPR, accessing a value in said TPR table to obtain a maximum data rate, said data rate dependent on said user class configured values; and
transmitting on said reverse traffic channel at said maximum data rate. - View Dependent Claims (13)
