Abstract

A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities and available transport frame combinations (TFCs) is disclosed. A mobile station has applications that produce separate data streams. Example applications include voice, signaling E-mail and web applications. The data streams are combined by a multiplexer module into one data stream called the transport stream. The transport stream is sent over the reverse link to base station transceivers (BTS). The multiplexer module multiplexes the data streams onto the transport stream according to their priorities and the available TFCs.

Claims

1. A method for use with a multiplexor, comprising:

receiving a set of transport format combinations (TFCs); and

removing a TFC from the received set based on whether at least one TFC in the received set requires padding blocks;

selecting from the received set, after the removal step, a TFC that allows the transmission of higher priority data streams from a plurality of data streams; and

multiplexing some of the plurality of data streams into the selected TFC.

2. The method of claim 1, further comprising filling the selected TFC with the high priority blocks from some of the plurality of data streams.

3. The method of claim 2, further comprising allocating the TFC to a single transport stream.

4. The method of claim 1, wherein the selected TFC includes more blocks from the highest priority data stream than other TFCs in the set of TFCs.

5. The apparatus of claim 1, wherein the selected TFC includes more blocks from the highest priority data stream than other TFCs in the set of TFCs.

6. An apparatus, comprising:

a multiplexer for receiving a set of transport format combinations (TFCs);

removing a TFC from the received set based on whether at least one TFC in the received set requires padding blocks; and

selecting from the received set, after the removal step, a TFC that allows the transmission of higher priority data streams from a plurality of data streams, wherein the apparatus comprises a subscriber unit.

7. The apparatus of claim 6, wherein the multiplexer is configured to fill the selected TEC with high priority blocks from some of the plurality of data streams.

8. The apparatus of claim 7, wherein the multiplexer is configured to allocate the TFC to a single transport stream.

9. A non-transitory computer-readable medium comprising:

code for causing a computer to receive a set of transport format combinations (TFCs); and

code for causing a computer to remove a TFC from the received set based on whether at least one TFC in the received set requires padding blocks;

code for causing a computer to select from the received set, after the removal step, a TFC that allows the transmission of higher priority data streams from a plurality of data streams.

10. The non-transitory computer-readable medium of claim 9, further comprising code for causing a computer high priority blocks from some of the plurality of data streams.

11. The computer program product of claim 10, further comprising code for causing a computer to allocate the TFC to a single transport stream.

12. The non-transitory computer-readable medium of claim 9, wherein the selected TFC includes more blocks from the highest priority data stream than other TFCs in the set of TFCs.

13. An apparatus comprising:

means for receiving a set of transport format combinations (TFCs); and

means for removing a TFC from the received set based on whether at least one TFC in the received set requires padding blocks;

means for selecting from the received set, after the removal, a TFC that allows the transmission of higher priority data streams from a plurality of data streams.

14. The apparatus of claim 13, further comprising means for filling the selected TFC with high priority blocks from some of the plurality of data streams.

15. The apparatus of claim 14, further comprising means for allocating the TFC to a single transport stream.

16. The apparatus of claim 13, wherein the selected TFC includes more blocks from the highest priority data stream than other TFCs in the set of TFCs.
