Title:
METHOD FOR POLAR CODING AND APPARATUS
Document Type and Number:
Japanese Patent JP2022031789
Kind Code:
A
Abstract:
To provide a coding method and apparatus and a decoding method and apparatus in a wireless communication network.SOLUTION: A method for polar coding includes interleaving a first bit sequence to obtain a first interleaved sequence having sequence numbers starting with a sequence number of 0. The first bit sequence comprises a set of bits for indicating synchronization signal block index (SSBI). The set of bits for indicating SSBI is placed in positions indicated by sequence numbers of 2, 3 and 5 in the first interleaved sequence. The method further includes adding D first CRC bits on the first interleaved sequence to obtain a second bit sequence, interleaving the second bit sequence according to an interleave pattern to obtain a second interleaved sequence, and finally polar encoding the second interleaved sequence.SELECTED DRAWING: Figure 3
