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 queue and a device;

wherein the device produces data for a plurality of channels including at least one common control channel (CCCH), at least one dedicated control channel (DCCH) and at least one dedicated traffic channel (DTCH);

wherein each of the plurality of channels is associated with a priority and a dynamically adjusted parameter which indicates a size limit of an amount of data for multiplexing for that channel;

wherein the size limit is based on requirements of the channel and the requirements of the plurality of channels differ;

wherein the device multiplexes the data of the plurality of channels based on the priority for transmission over a shared channel;

wherein hybrid automatic repeat request (H-ARQ) control information is transmitted on the shared channel and the H-ARQ control information is transmitted on the shared channel regardless of the priority of the plurality of channels.

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

3. The wireless communication apparatus of claim 1 wherein the size limits prevents monopolization of the shared channel by one of the plurality of channels.

4. The wireless communication apparatus of claim 1 wherein the wireless communication apparatus is a user equipment.

5. A method comprising:

producing, by a wireless communication apparatus comprising a queue and a device, data for a plurality of channels including at least one common control channel (CCCH), at least one dedicated control channel (DCCH) and at least one dedicated traffic channel (DTCH);

wherein each of the plurality of channels is associated with a priority and a dynamically adjusted parameter which indicates a size limit of an amount of data for multiplexing for that channel;

wherein the size limit is based on requirements of the channel and the requirements of the plurality of channels differ; and

multiplexing based on the priority, by the wireless communication apparatus, the data of the plurality of channels for transmission over a shared channel;

wherein hybrid automatic repeat request (H-ARQ) control information is transmitted on the shared channel and the H-ARQ control information is transmitted on the shared channel regardless of the priority of the plurality of channels.

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

7. The method of claim 5 wherein the size limits prevents monopolization of the shared channel by one of the plurality of channels.
