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 wireless communication apparatus comprising:

a device configured to produce data for a plurality of channels, wherein each of the plurality of channels is associated with a priority and a dynamically adjusted parameter to prevent monopolization of a shared channel by one of the plurality of channels;

the device configured to multiplex the data of the plurality of channels based on the priority for transmission over the shared channel, wherein hybrid automatic repeat request (H-ARQ) control information is multiplexed onto the shared channel.

2. The apparatus of claim 1 wherein the dynamically adjusted parameter indicates a size limit of an amount of data for multiplexing for that channel.

3. The apparatus of claim 2 wherein the size limit is based on requirements of the channel and the requirements of the plurality of channels differ.

4. The apparatus of claim 1 wherein the H-ARQ control information is multiplexed regardless of the priority of the plurality of channels.

5. The apparatus of claim 1 wherein the multiplexing of the plurality of channels is performed by a medium access controller (MAC).

6. The apparatus of claim 1 wherein the priority is based on whether the data is best effort or not best effort.

7. The apparatus of claim 1 wherein each channel is associated with a dedicated traffic channel (DTCH).

8. The apparatus of claim 1 wherein the plurality of channels include at least one common control channel (CCCH), at least one dedicated control channel (DCCH), and at least one dedicated traffic channel (DTCH).

9. A method for use in a wireless communication device comprising:

producing data for a plurality of channels, wherein each of the plurality of channels is associated with a priority and a dynamically adjusted parameter to prevent monopolization of a shared channel by one of the plurality of channels; and

multiplexing the data of the plurality of channels based on the priority for transmission over the shared channel, wherein hybrid automatic repeat request (H-ARQ) control information is multiplexed onto the shared channel.

10. The method of claim 9 wherein the dynamically adjusted parameter indicates a size limit of an amount of data for multiplexing for that channel.

11. The method of claim 10 wherein the size limit is based on requirements of the channel and the requirements of the plurality of channels differ.

12. The method of claim 9 wherein the H-ARQ control information is multiplexed regardless of the priority of the plurality of channels.

13. The method of claim 9 wherein the multiplexing of the plurality of channels is performed by a medium access controller (MAC).

14. The method of claim 9 wherein the priority is based on whether the data is best effort or not best effort.

15. The method of claim 9 wherein each channel is associated with a dedicated traffic channel (DTCH).

16. The method of claim 9 wherein the plurality of channels include at least one common control channel (CCCH), at least one dedicated control channel (DCCH), and at least one dedicated traffic channel (DTCH).
