Abstract

Disclosed in the present specification is a method for performing channel encoding. The method can comprise the steps of: interleaving information bits; and encoding the interleaved information bits by using a polar code. The information bits can be interleaved according to an interleaving pattern.

Claims

1. A method of performing channel encoding, the method comprising:

interleaving information bits; and

encoding the interleaved information bits into a polar code,

wherein the information bits are interleaved according to an interleaving pattern.

2. The method according to claim 1,

wherein the interleaving pattern is determined according to a value of N, and

wherein N indicates a size of the information bits.

3. The method according to claim 1, wherein the interleaving pattern is predefined in the form of a table.

4. The method according to claim 1, wherein the information bits are reordered in ascending order of reliability.

5. The method according to claim 1, wherein, when the information bits have a size of K, bits output after encoding have a size of N.

6. The method according to claim 1, wherein the information bits include uplink control information (UCI) of a physical uplink control channel (PUCCH).

7. The method according to claim 1, wherein the information bits include uplink control information (UCI) of a physical uplink shared channel (PUSCH).

8. The method according to claim 1, wherein the information bits include downlink control information (DCI) of a downlink control channel or data of a downlink data channel.

14. The UE according to claim 6, wherein the information bits include uplink control information (UCI) of a physical uplink control channel (PUCCH).

9. A user equipment (UE) for performing channel encoding, the UE comprising:

a transceiver; and

a processor for controlling the transceiver,

wherein the processor performs a process of interleaving information bits and a process of encoding the interleaved information bits into a polar code,

wherein the information bits are interleaved according to an interleaving pattern.

10. The UE according to claim 9,

wherein the interleaving pattern is determined according to a value of N, and

wherein N indicates a size of the information bits.

11. The UE according to claim 9, wherein the interleaving pattern is predefined in the form of a table.

12. The UE according to claim 9, wherein the information bits are reordered in ascending order of reliability.

13. The UE according to claim 9, wherein, when the information bits have a size of K, bits output after encoding have a size of N.

15. The UE according to claim 9, wherein the information bits include uplink control information (UCI) of a physical uplink shared channel (PUSCH).
