Problems solved by technology

[0006] Since the existing descrambling and demodulation processing is based on the entire transmission block length, with the complexity of LTE system configuration, the amount of descrambling and demodulation processing gradually increases, which is not conducive to the real-time processing of the system, making the system The hardware implementation of the

Embodiment Construction

[0048] The specific embodiments of the invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0049] figure 2 It shows a schematic flowchart of a method for receiving and processing a code block provided by this embodiment, as shown in figure 2 As shown, the method includes the following steps:

[0050] 101. The terminal receives a signal sent by the base station, and performs symbol-level code block segmentation on the signal;

[0051] For example, the above step 101 may specifically be: if the number M of modulation symbols is not greater than the number Z of division symbols of the code block, then the division number C of the code block is 1;

[0052] If the number of modulation symbols M is greater than the number of division symbols Z of the code block, the...

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 ...
