Embodiment Construction

[0022] As mentioned above, in a New Radio (NR) system, an LDPC decoder is usually used to decode input log-likelihood ratio (Log-Likelihood Ratio, LLR) information. After research, it is found that the length of the verification information remains unchanged. When the proportion of system information is smaller, the decoding performance of the system is worse. When the length of the system information is lower than a certain threshold, the system decoding always fails. When the length of the effective information actually received in the LLR information is short, even if the LDPC decoder is configured with a large number of iterations, it still cannot be decoded to obtain the correct information, the decoding result is wrong, and the system consumes a lot of power.

[0023] In order to solve the above problems, in the embodiment of the present invention, according to the ratio of the actually received effective system information length to the preset system information length i...

Abstract

A decoding control method and device, a terminal and a storage medium are disclosed, the decoding control method comprising: obtaining to-be-decoded LLR information, the to-be-decoded LLR informationcomprising system information and check information; calculating the ratio of the length of actually received effective system information in the to-be-decoded LLR information to the preset system information length of the to-be-decoded LLR information; and when the ratio is smaller than a set threshold value, controlling a decoder to be in a non-starting state. According to the scheme, the systempower consumption during decoding can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a decoding control method and device, a terminal, and a storage medium. Background technique [0002] Low Density Parity Check Code (Low Density Parity Check Code, LDPC) is a kind of linear block code with sparse parity check matrix, which has the characteristics of flexible structure and low decoding complexity. In a New Radio (NR) system, an LDPC decoder is usually used to decode input log-likelihood ratio (Log-Likelihood Ratio, LLR) information. [0003] However, in some scenarios, especially when the decoding result is wrong, there is a problem of high system power consumption. Contents of the invention [0004] The technical problem solved by the embodiments of the present invention is that in some scenarios, the power consumption of the system is relatively large. [0005] In order to solve the above technical problems, an embodiment of the prese...
