Abstract

A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

Claims

1. A code division multiple access (CDMA) subscriber unit device comprising:

a controller configured to establish a communication session, including at least a network layer session to transfer packet data;

a receiver and the controller configured to receive data over a physical layer comprising sixteen CDMA channels;

wherein each of the sixteen CDMA channels has a different Walsh code; and

the controller further configured to maintain at least the network layer session when the physical layer, including the sixteen CDMA channels has been released.

2. The CDMA subscriber unit of claim 1 wherein the received data is a burst of data.

3. The CDMA subscriber unit of claim 1 wherein the received data is webpage data.

4. The CDMA subscriber unit of claim 1 wherein the received data includes voice data.

5. The CDMA subscriber unit of claim 1 wherein the controller is further configured to enter a dormant state when no data is received and the network layer session is maintained.

6. The CDMA subscriber unit of claim 1 wherein the receiver and the controller are further configured to receive control information which was based on a data rate associated with the received data.

7. The CDMA subscriber unit of claim 1 wherein the received data is received over the sixteen channels within a 1.25 MHz bandwidth.

8. The CDMA subscriber unit of claim 1 wherein the sixteen CDMA channels are received as a burst.

9. A code division multiple access (CDMA) base station comprising:

a controller configured to establish a communication session, including at least a network layer to transfer packet data;

a transmitter and the controller configured to transmit data over a physical layer comprising sixteen CDMA channels to a CDMA subscriber unit, wherein each of the sixteen CDMA channels has a different Walsh code; and

the controller further configured to maintain at least the network layer session when the physical layer, including the CDMA sixteen CDMA channels has been released.

10. The CDMA base station of claim 9 wherein the transmitted data is a burst of data.

11. The CDMA base station of claim 9 wherein the transmitted data is webpage data.

12. The CDMA base station of claim 9 wherein the transmitted data includes voice data.

13. The CDMA base station of claim 9 wherein the controller is further configured to allocate the sixteen CDMA channels to the CDMA subscriber unit based on a priority associated with the transmitted data.

14. The CDMA base station of claim 9 wherein the transmitter and the controller are further configured to transmit control information which was based on a data rate associated with the transmitted data.

15. The CDMA base station of claim 9 wherein the transmitted data is transmitted over the sixteen channels within a 1.25 MHz bandwidth.

16. The CDMA base station of claim 9 wherein the sixteen CDMA channels are transmitted as a burst.

17. The CDMA base station of claim 9 wherein the controller is further configured to determine a data rate associated with the sixteen CDMA channels transmission based on a priority associated with the transmitted data.

18. The CDMA base station of claim 17 wherein the data rate is based on a short term data rate.
