Abstrakt: 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.
Claim: 20. An apparatus of wireless communications, comprising: at least one processor configured to: select, 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; generate a codeword by encoding the information bits using the type of code selected as the inner code and an outer code; and transmit the codeword; and a memory coupled to the at least one processor.
Claim: 21. The apparatus of claim 20, 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: 28. The apparatus of claim 27, wherein the at least one processor is configured to select 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.
Claim: 29. A computer-readable medium for wireless communications, for storing instructions which when executed by at least one processor performs a method 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.
