Abstract

A code division multiple access (CDMA) communication device comprises a medium access controller (MAC) configured to receive data from a plurality of channels. Each channel is associated with a priority and an identifier. The MAC is further configured to multiplex the data of the plurality of channels for transmission over a CDMA channel based on the priority.

Claims

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

a medium access controller (MAC) configured to receive data from a plurality of channels;

wherein each channel is associated with a priority and an identifier;

wherein the MAC is further configured to multiplex the data of the plurality of channels for transmission over a CDMA channel based on the priority;

wherein the multiplexed data includes the identifier associated with the plurality of channels of the multiplexed data.

2. The communication device of claim 1 wherein the priority is based on whether the data is best effort or not best effort.

3. The communication device of claim 1 wherein the MAC is configured to receive H-ARQ signaling.

4. The communication device of claim 1 wherein each channel is associated with a DTCH data flow.

5. The communication device of claim 1 wherein the communication device is a radio network controller.

6. The communication device of claim 1 wherein the MAC is configured to receive data for the plurality of channels from a MAC-d.

7. The communication device of claim 1 wherein the MAC is a MAC-c or a MAC-sh.

8. A code division multiple access (CDMA) communication device comprising:

at least one component configured to implement a medium access control (MAC) function;

wherein the MAC function receives data from a plurality of channels;

wherein each channel is associated with a priority and an identifier;

wherein the MAC function multiplexes the data of the plurality of channels for transmission over a CDMA channel based on the priority;

wherein the multiplexed data includes the identifier associated with the plurality of channels of the multiplexed data.

9. The communication device of claim 8 wherein the priority is based on whether the data is best effort or not best effort.

10. The communication device of claim 8 wherein the MAC function receives H-ARQ signaling.

11. The communication device of claim 8 wherein each channel is associated with a DTCH data flow.

12. The communication device of claim 8 wherein the MAC function receives data for the plurality of channels from a MAC-d function.

13. The communication device of claim 8 wherein the MAC function is a MAC-c function or a MAC-sh function.

14. The communication device of claim 8 wherein the communication device is a radio network controller.

15. A code division multiple access (CDMA) communication device comprising:

receiving data from a plurality of channels by a medium access controller (MAC) of the communication device;

wherein each channel is associated with a priority and an identifier; and

multiplexing the data of the plurality of channels by the MAC for transmission over a CDMA channel based on the priority;

wherein the multiplexed data includes the identifier associated with the plurality of channels of the multiplexed data.

16. The communication device of claim 15 wherein the priority is based on whether the data is best effort or not best effort.

17. The communication device of claim 15 wherein the MAC is configured to receive H-ARQ signaling.

18. The communication device of claim 15 wherein each channel is associated with a DTCH data flow.

19. The communication device of claim 15 wherein the communication device is a radio network controller.

20. The communication device of claim 15 wherein the MAC is configured to receive data for the plurality of channels from a MAC-d.

21. The communication device of claim 15 wherein the MAC is a MAC-c or a MAC-sh.
