Methods and apparatus are provided for selecting a code type. A type of code is selected from a set of code types to use as an inner code for a concatenated encoding scheme for encoding information bits of a channel, wherein the selection is based on one or more channel coding parameters including a false alarm detection objective for the channel. A codeword is generated by encoding the information bits using the type of codes selected as the inner code and an outer code. The generated codeword is transmitted. |
| Claim: |
1. A method of wireless communications, comprising: selecting, from a set of code types, a type of code to use as an inner code for a concatenated coding scheme for encoding information bits of a channel, wherein the selection is based on a false alarm detection objective for the channel; generating a codeword by encoding the information bits using the type of code selected as the inner code and an outer code; and transmitting the codeword. |
| Claim: |
2. The method of claim 1, wherein the outer code comprises a cyclic redundancy check (CRC), wherein a number of bits for the CRC is based on the false alarm detection objective for the channel. |
| Claim: |
3. The method of claim 1, wherein the false alarm detection objective depends on a type of the physical channel. |
| Claim: |
4. The method of claim 1, wherein the false alarm detection objective depends on a number of retransmissions of the channel. |
| Claim: |
5. The method of claim 1, wherein information regarding the false alarm detection objective is signaled via radio resource control (RRC) signaling. |
| Claim: |
6. The method of claim 1, wherein the set of code types comprises at least a Reed-Muller code type and a polar code type. |
| Claim: |
7. The method of claim 1, wherein selecting comprises selecting further based on at least one of a number of information bits of the channel to be encoded, or a list decoding size. |
| Claim: |
8. The method of claim 7, further comprising: generating a metric as a function of the number of information bits, the false alarm detection objective, and the list decoding size; and selecting the type of code based on the metric. |
| Claim: |
9. The method of claim 8, wherein the selecting comprises: selecting a polar code type if the metric is equal to or exceeds a threshold value: or selecting a Reed-Muller code type if the metric is below the threshold value. |
| Claim: |
10. The method of claim 1, further comprising determining a number of assistant parity bits to use for the inner code in the concatenated coding scheme based, at least in part, on a code parity bit length of the outer code. |
| Claim: |
11. An apparatus for wireless communications, comprising: means for selecting, from a set of code types, a type of code to use as an inner code for a concatenated coding scheme for encoding information bits of a channel, wherein the selection is based on a false alarm detection objective for the channel; means for generating a codeword by encoding the information bits using the type of code selected as the inner code and an outer code; and means for transmitting the codeword. |
| Claim: |
12. The apparatus of claim 11, wherein the outer code comprises a cyclic redundancy check (CRC), wherein a number of bits for the CRC is based on the false alarm detection objective for the channel. |
| Claim: |
13. The apparatus of claim 11, wherein the false alarm detection objective depends on a type of the physical channel. |
| Claim: |
14. The apparatus of claim 11, wherein the false alarm detection objective depends on a number of retransmissions of the channel. |
| Claim: |
15. The apparatus of claim 11, wherein information regarding the false alarm detection objective is signaled via radio resource control (RRC) signaling. |
| Claim: |
16. The apparatus of claim 11, wherein the set of code types comprises at least a Reed-Muller code type and a polar code type. |
| Claim: |
17. The apparatus of claim 11, wherein the wherein the means for selecting selects further based on at least one of a number of information bits of the channel to be encoded, or a list decoding size. |
| Claim: |
18. The apparatus of claim 17, further comprising: means for generating a metric as a function of the number of information bits, the false alarm detection objective, and the list decoding size; and means for selecting the type of code based on the metric. |
| Claim: |
19. The apparatus of claim 18, wherein the means for selecting selects the type of code by: selecting a polar code type if the metric is equal to or exceeds a threshold value; or selecting a Reed-Muller code type if the metric is below the threshold value. |
