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 drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0049] figure 2 Shows a schematic flow chart of a code block receiving and processing method provided by this embodiment, such as figure 2 As shown, the method includes the following steps:

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

[0051] For example, the foregoing step 101 may specifically be: if the number of modulation symbols M is not greater than the number of division symbols Z of the code block, the number of division 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, then the number of divisions o...

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 field of communications, in particular to a method and device for receiving and processing code blocks. Background technique [0002] In the current LTE system, a new transmission mode is introduced in the downlink. The transmission antenna precoding based on the dual codebook structure can support up to 8 layers of SU-MIMO, and the corresponding transmission block bit number is increased to a maximum of 299856 bits. Modulation methods have also been extended from QPSK, 16QAM, and 64QAM to higher-order modulation methods supporting 256QAM, and the number of corresponding transmission block bits has also increased to a maximum of 391656 bits. [0003] The bit-level processing of the LTE system generally uses Turbo coding, and the maximum input bit length of the Turbo code is limited to 6144 bits. Due to the fact that the number of transmission block bits is greater than 6144 bits, the LTE system adopts the code block segme...
