example 11

[0071] Example 1.1: According to the reliability of the Polar code from low to high, the arrangement order of the above four types of bits can be as follows:

[0072] First type bits, second type bits, third type bits, fourth type bits, CRC bits;

[0073] According to the examples of each type of bit, according to the above order, for example: the first type of bit including Reserved bit, the second type of bit including bandwidth information and general control channel configuration information; the third type of bit including timing information Class bits, including the fourth class bits indicated by the SIB, and CRC bits.

[0074] According to the above arrangement order, it is mapped to the low reliability position of the Polar code from low reliability to high reliability.

[0075] Example 1.2: According to the reliability of the Polar code from low to high, the arrangement order of the above four types of bits can be as follows:

[0076] First type bits, second type bits, third type bits, fourth type bits, CRC bits;

[0077] According to the examples of each type of bit, according to the above order, for example: the first type of bit including Reserved bit, the second type of bit including general control channel configuration information and bandwidth information; the third type of bit including timing information Class bits, including the fourth class bits indicated by the SIB, and CRC bits.

[0078] The internal order of the second type of bits in the first 1.2 example is sorted, and the order of the same type can be exchanged

[0079] According to the above arrangement order, it is mapped to the low reliability position of the Polar code from low reliability to high reliability.

[0080] Example 1.3: According to the reliability of the Polar code from low to high, the arrangement order of the above four types of bits can be as follows:

[0081] The first type of bits, the second type of bits and the third type of bits, the fourth type of bits, CRC bits;

[0082] According to the examples of each type of bits, according to the above order, examples are: the first type of bits including Reserved bits, the second type of bits including general control channel configuration information, timing information, and bandwidth information; including timing The second type of bits and the third type of bits of the information, including the fourth type of bits indicated by the SIB, and the CRC bits.

[0083] The difference between this example and the above example is that the second type of bits can be combined with the third type of bits, that is, in the divided bit set, the second type of bits and the third type of bits are divided into one type, and this type c...

Abstract

The invention discloses a polar code encoding method and an encoding device. The method comprises the following steps of: determining the payload of the broadcast signaling payload comprises D cyclicredundancy check CRC bits and M predictable information bits; mapping the M predictable information bits to the less reliable M information bits of the K information bits of the polar code, and mapping D cyclic redundancy check CRC bits to the D information bits with high reliability among the remaining information bits of the K information bits to obtain mapped bits, wherein M(K, and D, M and K are positive integers; polar code encoding the mapped bits to obtain encoded coded bits. The polar code encoding method and encoding device can improve the reliability of broadcast signaling transmission.

Description

technical field [0001] Embodiments of the present invention relate to the field of encoding and decoding, and more specifically, relate to an encoding method and an encoding device of a polar code. Background technique [0002] Communication systems usually use channel coding to improve the reliability of data transmission and ensure the quality of communication. Polar codes (Polar codes) are encoding methods that can achieve Shannon capacity and have low encoding and decoding complexity. Polar code is a linear block code, including information bits and frozen bits. The generator matrix of the Polar code is G N. , whose encoding process is here, is a binary row vector of length N. [0003] However, when using Polar codes for physical broadcast channel (Physical Broadcast Channel, PBCH) channel coding, there is still room for further improvement in the transmission reliability of the broadcast channel. Contents of the invention [0004] The application provides a c...
