Abstract

An ordered number sequence may be determined based on an ordered sub-channel sequence specifying an order of N sub-channels that are defined by a code and that have associated reliabilities for input bits at N input bit positions. The ordered number sequence represents the ordered sub-channel sequence as a sequence of fewer than N numbers. The numbers in the ordered number sequence indicate the sub-channels, by representing numbers of the sub-channels for example, from different subsets of the N sub-channels, that appear in the order specified by the ordered sub-channel sequence. Using ordered number sequences, longer ordered sub-channel sequences could be constructed from smaller ordered sub-channel sequences, and/or sub-channels that to be selected from a longer ordered sub-channel sequence could be divided into two or more parts, with each part to be selected from shorter ordered sub-channel sequences.

First claim

The invention claimed is:

1. A method comprising:
selecting, by circuitry, from coding sub-channels that are defined by a code and that have associated reliabilities for input bits at input bit positions, sub-channels to carry bits that are to be encoded; the selecting being based on an ordered number sequence and an ordered sequence of the coding sub-channels in order of the reliabilities; the ordered number sequence comprising a sequence of numbers indicating sub-channels from subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

2. The method of claim 1 , wherein the sequence of numbers indicates numbers of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

3. The method of claim 1 , wherein the sequence of numbers indicates positions of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

4. The method of claim 1 , wherein the sequence of numbers indicates the subsets of the coding sub-channels.

5. The method of claim 1 , wherein the sequence of numbers alternates between numbers associated with respective subsets of the coding sub-channels.

6. The method of claim 5 , wherein the sequence of numbers transitions only once between numbers associated with any two of the subsets of the coding sub-channels.

7. The method of claim 1 , wherein the selecting is further based on one or more additional ordered number sequences.

8. The method of claim 7 , wherein the one or more additional ordered number sequences comprise an additional ordered number sequence that includes a sequence of numbers indicating sub-channels from additional subsets of the coding sub-channels that are smaller than the subsets of the coding sub-channels.

9. The method of claim 7 , wherein the one or more additional ordered number sequences comprise a plurality of additional ordered number sequences that respectively include numbers indicating sub-channels from different sizes of subsets of the coding sub-channels.

10. The method of claim 7 , wherein the sequence of numbers indicates numbers of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels, wherein the one or more additional ordered number sequences comprise an additional ordered number sequence that indicates the subset with which each number in the sequence of numbers is associated.

11. The method of claim 1 , wherein the selecting comprises selecting the sub-channels on-the-fly as needed to carry the bits that are to be encoded.

12. The method of claim 1 , further comprising:
encoding the bits that are to be encoded onto the selected sub-channels to generate a codeword.

13. The method of claim 12 , further comprising:
transmitting the codeword.

14. A non-transitory processor-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform the method of claim 1 .

15. An apparatus comprising:
circuitry implementing a sub-channel processing module to select, from coding sub-channels that are defined by a code and that have associated reliabilities for input bits at input bit positions, sub-channels to carry bits that are to be encoded; the sub-channel processing module being configured to select the sub-channels based on an ordered number sequence and an ordered sequence of the coding sub-channels in order of the reliabilities; the ordered number sequence comprising a sequence of numbers indicating sub-channels from subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

16. The apparatus of claim 15 , wherein the sequence of numbers indicates numbers of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

17. The apparatus of claim 15 , wherein the sequence of numbers indicates positions of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels.

18. The apparatus of claim 15 , wherein the sequence of numbers indicates the subsets of the coding sub-channels.

19. The apparatus of claim 15 , wherein the sequence of numbers alternates between numbers associated with respective subsets of the coding sub-channels.

20. The apparatus of claim 19 , wherein the sequence of numbers transitions only once between numbers associated with any two of the subsets of the coding sub-channels.

21. The apparatus of claim 15 , wherein the sub-channel processing module is configured to select the sub-channels further based on one or more additional ordered number sequences.

22. The apparatus of claim 21 , wherein the one or more additional ordered number sequences comprise an additional ordered number sequence that includes a sequence of numbers indicating sub-channels from additional subsets of the coding sub-channels that are smaller than the subsets of the coding sub-channels.

23. The apparatus of claim 21 , wherein the one or more additional ordered number sequences comprise a plurality of additional ordered number sequences that respectively include numbers indicating sub-channels from different sizes of subsets of the coding sub-channels.

24. The apparatus of claim 21 , wherein the sequence of numbers indicates numbers of the sub-channels from the subsets of the coding sub-channels in the ordered sequence of the coding sub-channels, wherein the one or more additional ordered number sequences comprise an additional ordered number sequence that indicates the subset with which each number in the sequence of numbers is associated.

25. The apparatus of claim 15 , wherein the sub-channel processing module is configured to select the sub-channels on-the-fly as needed to carry the bits that are to be encoded.

26. The apparatus of claim 15 , further comprising:
an encoder, coupled to the sub-channel processing module, to encode the bits that are to be encoded onto the selected sub-channels to generate a codeword.

27. The apparatus of claim 26 , further comprising:
a transmitter, coupled to the encoder, to transmit the codeword.

28. User equipment comprising the apparatus of claim 15 .

29. Communication network equipment comprising the apparatus of claim 15 .
