Abstract

The invention discloses a code block receiving and processing method and device. The method comprises the following steps that: a terminal receives a signal sent by a base station; the terminal performs symbol level code block division of the signal; the terminal performs same demodulation and descrambling treatments of a divided symbol in each code block; and the terminal performs bit-level treatments of a descrambled bit sequence of each code block, such that a received transmission block sequence is formed. According to the method disclosed by the invention, the demodulation and descrambling treatments based on the code block level are combined with treatments based on the code block, such as bit-level rate de-matching and channel decoding; therefore, the treatment capacity of a system is simplified and reduced; and the method is also suitable for parallel treatment design in a hardware environment.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a code block receiving and processing method and device. Background technique

[0002] In the current LTE system, a new transmission mode is introduced in the downlink. Based on the transmit antenna precoding of the dual codebook structure, it can support up to 8 layers of SU-MIMO, and the corresponding number of transmission block bits increases to a maximum of 299856 bits. The modulation method is also extended from QPSK, 16QAM, 64QAM to a higher order modulation method supporting 256QAM, and the corresponding number of transmission block bits is also increased to a maximum of 391656 bits.

[0003] The bit-level processing of the LTE system generally adopts Turbo coding, and the maximum input bit length of the Turbo code is limited to 6144 bits. Since there are cases where the number of transmission block bits is greater than 6144 bits, the code block segmentation technology ...
