Abstract

Claims (46)

1. A method of communicating data in a wireless communications network, comprising:

communicating, between a mobile station and base station, an indicator of an autonomous data rate supportable over a reverse wireless link between the mobile station and the base station, wherein the mobile station is involved in plural sessions corresponding to plural services;

communicating, between the mobile station and the base station, a first flag indicating whether autonomous mode is enabled for a first one of the services:

in response to the first flag indicating that autonomous mode is enabled, communicating, over the reverse wireless link, data at a data rate less than or equal to the autonomous data rate without the base station having to first schedule the mobile station; and

communicating at least a second flag indicating whether autonomous mode is enabled for at least a second one of the services.

2. The method of claim 1 , further comprising:

the mobile station autonomously sending data associated with the first service in response to detecting that the first flag indicates that autonomous mode is enabled for the first service; and

the mobile station autonomously sending data associated with the second service in response to detecting that the second flag indicates that autonomous mode is enabled for the second service.

3. The method of claim 2 , wherein the mobile station autonomously sends data associated with the first service at a data rate that is less than or equal to the autonomous data rate, and

wherein the mobile station autonomously sends data associated with the second service at a data rate that is less than or equal to the autonomous data rate.

4. The method of claim 1 , wherein communicating the first flag comprises communicating the first flag having a state to indicate that autonomous mode is disabled for the first service, and

wherein communicating the second flag comprises communicating the second flag having a state to indicate that autonomous mode is enabled for the second service.

5. The method of claim 1 , wherein communicating the data comprises communicating packet data over a reverse packet data channel (R-PDCH in a code-division multiple access (CDMA) wireless communications network.

6. The method of claim 5 , wherein communicating the indicator comprises communicating a REV_PDCH_MAX_AUTO_TPR s parameter.

7. The method of claim 6 , wherein communicating the flag comprises communicating a REV_PDCH_AUTO_ALLOWED s [i] parameter.

8. A method of communicating data in a wireless communications network, comprising:

communicating, between a mobile station and base station, an indicator of an autonomous data rate supportable over a reverse wireless link between the mobile station and base station;

communicating, between the mobile station and base station, a flag indicating whether autonomous mode is enabled for the mobile station;

in response to the flag indicating that autonomous mode is enabled, communicating, over the reverse wireless link, data at a data rate less than or equal to the autonomous data rate without the base station having to first schedule the mobile station, wherein communicating the data comprises communicating packet data over a reverse packet data channel (R-PDCH) in a code-division multiple access (CDMA) wireless communications network, wherein communicating the indicator comprises communicating a REV_PDCH_MAX_AUTO_TPR s parameter;

communicating, between the mobile station and the base station, data according to plural services over the reverse wireless link;

communicating REV_PDCH_AUTO_ALLOWED s [i] parameters where i is equal to a range of values corresponding to the plural services, wherein the flag is one of the REV_PDCH_AUTO_ALLOWED s [i] parameters, and wherein the REV_PDCH_AUTO_ALLOWED s [i] parameters indicate whether autonomous mode is enabled for respective ones of the plural services.

9. The method of claim 1 , further comprising communicating, in the reverse wireless link, a message indicating a maximum supportable data rate of the mobile station a predetermined time offset prior to communicating data corresponding to the message.

10. The method of claim 9 , further comprising scheduling communications for other mobile stations based at least in part on the message indicating the maximum supportable data rate.

11. The method of claim 1 , wherein communicating the indicator and flag comprises communicating the indicator and flag in at least one of an Extended Channel Assignment Message. a Service Connect Message, and a Universal Handoff Direction Message.

12. An article comprising at least one computer-readable storage medium encoded with computer-executable instructions that when executed cause a base station in a wireless communications network to:

communicate, in a forward wireless link, an indicator of an autonomous data rate supportable over a reverse wireless link between a mobile station and the base station, wherein the mobile station is involved in plural sessions corresponding to plural services;

communicate, in the forward wireless link, a first flag indicating whether autonomous mode is enabled for a first one of the services;

in response to the first flag indicating that autonomous mode is enabled, perform autonomous communication over the reverse wireless link between the mobile station and the base station at a data rate less than or equal to the autonomous data rate without the base station having to first schedule the mobile station; and

communicate at least a second flag indicating whether autonomous mode is enabled for at least a second one of the services.

13. The article of claim 12 , wherein the instructions when executed cause the base station to communicate packet data in autonomous mode over a reverse packet data channel (R-PDCH) in a code-division multiple access (CDMA) wireless communications network.

14. The article of claim 13 , wherein the indicator comprises a REV_PDCH_MAX_AUTO_TPR s parameter.

15. The article of claim 14 , wherein the first flag comprises a REV_PDCH_AUTO_ALLOWED s [i] parameter.

16. A base station for use in a wireless communications network, comprising:

an interface to transmit to a first mobile station an indicator of an autonomous data rate supportable over a reverse wireless link between the first mobile station and base station, wherein the first mobile station is involved in plural sessions corresponding to plural services,

the interface to further transmit to the first mobile station a first flag indicating whether autonomous mode is enabled for a first one of the services, the first flag being separate from the indicator, and the interface to further transmit at least a second flag indicating whether autonomous mode is enabled for at least a second one of the services;

a scheduler to schedule transmission of data by mobile stations; and

a controller to receive data transmitted by the first mobile station in autonomous mode in response to the first flag being enabled without the scheduler having to schedule transmission by the first mobile station, the received data communicated over the reverse wireless link at a data rate less than or equal to the autonomous data rate.

17. A mobile station for use in a wireless communications network, comprising:

an interface to receive an indicator of an autonomous data rate supportable over a reverse wireless link between the mobile station and a base station, wherein the mobile station is involved in plural sessions corresponding to plural services,

the interface to further receive a first flag indicating whether autonomous mode is enabled for a first one of the services, and to receive at least a second flag indicating whether autonomous mode is enabled for a second one of the services; and
