Problems solved by technology

Therefore, for the above two cases, different types of decoders need to be set up for decoding (one type of decoder is embedded with a CB_CRC verification module, and the other type of decoder is embedded with a TB_CRC verification module), and the decoder is generally Realized by complex hardware circuits, therefore, setting two different types of decoders at the decoding end and switching between different types of decoders will increase the complexity of hardware implementation at the decoding end

Abstract

The present application provides an encoding method, a decoding method, an encoding device and a decoding device. The encoding method includes: obtaining a transmission block TB; adding TB_CRC to the TB, and the TB_CRC is used to perform a CRC check on the TB; determining the length corresponding to the TB after adding the TB_CRC; the length corresponding to the TB after adding the TB_CRC is less than or equal to a preset length In the case of TB_CRC, the TB after adding TB_CRC is determined as the coding block CB; CB_CRC is added to CB, and CB_CRC is used to perform CRC check on CB; and the CB after adding CB_CRC is encoded. The present application can reduce the complexity of hardware implementation at the decoding end.

Description

technical field [0001] The present application relates to the field of communication technologies, and more specifically, to an encoding method, a decoding method, an encoding device, and a decoding device. Background technique [0002] In the LTE system, when encoding the transport block (Transport Block, TB), the encoder generally first adds a CRC check digit (TB_CRC) to the TB, and then determines the length corresponding to the TB after adding the TB_CRC check digit. Then determine the subsequent encoding method according to the relationship between the length corresponding to the TB after adding the TB_CRC and the preset length. If the length corresponding to the TB after adding TB_CRC is less than or equal to the preset length, then the encoder will no longer divide the TB (at this time, the TB corresponds to a CB), but directly encode the TB; if the TB after adding TB_CRC If the length corresponding to the TB is greater than the preset length, then it is necessary to...
