Abstract

A turbo-coded data block is processed for transmission on a wireless communication link by scheduling a plurality of portions of the block for transmission during respectively corresponding transmit intervals that are temporally separated from one another. The block portions are transmitted during the respectively corresponding transmit intervals according to the scheduling.

Claims

1. A method of processing a turbo-coded data block for transmission on a wireless communication link, comprising:

scheduling a plurality of portions of the turbo-coded data block for transmission during respectively corresponding transmit intervals that are temporally separated from one another; and

transmitting said portions during the respectively corresponding transmit intervals according to said scheduling.

2. The method of claim 1, wherein said transmit intervals are equal in length.

3. The method of claim 2, wherein said transmit intervals are equally separated from one another temporally.

4. The method of claim 1, wherein said transmit intervals are equally separated from one another temporally.

5. The method of claim 1, wherein each of said portions contains a plurality of bits.

6. The method of claim 1, wherein each of said portions consists of a single bit.

7. The method of claim 6, including re-ordering bits of said turbo-coded block before said scheduling.

8. The method of claim 1, including re-ordering bits of said turbo-coded block before said scheduling.

9. An apparatus for processing a turbo-coded data block for transmission on a wireless communication link, comprising:

a scheduler configured for scheduling a plurality of portions of the turbo-coded data block for transmission during respectively corresponding transmit intervals that are temporally separated from one another; and

a transmitter coupled to said scheduler and configured to transmit said portions during the respectively corresponding transmit intervals according to said scheduling.

10. An apparatus for processing a turbo-coded data block for transmission on a wireless communication link, comprising

means for scheduling a plurality of portions of the turbo-coded data block for transmission during respectively corresponding transmit intervals that are temporally separated from one another;

and

means for transmitting said portions during the respectively corresponding transmit intervals according to said scheduling.

11. A computer program product, comprising:

a computer-readable medium comprising;

code for causing at least one data processor to schedule a plurality of portions of the turbo-coded data block for transmission during respectively corresponding transmit intervals that are temporally separated from one another; and

code for causing the at least one data processor to effectuate transmission of said portions during the respectively corresponding transmit intervals according to said scheduling.
