Abstract: Embodiments of this application provide a terminal configuration method and an apparatus. When determining that a SIM card in a terminal is powered on, a wireless communications module reads SIM card information such as some or all of an international mobile subscriber identity IMSI, a service provider name SPN, or a global identifier ID GID in the SIM card from the SIM card. Then, the SIM card information obtained by the wireless communications module is sent to an application processor. The application processor obtains an operator parameter based on the SIM card information reported by the wireless communications module, and configures the terminal. Therefore, at a moment at which the SIM card is powered on, the wireless communications module obtains the SIM card information from the SIM card, so that a timing for the UE to obtain the IMSI is advanced.

Abstract: This application discloses an information processing method and apparatus, a communications device, and a communications system. The method includes: encoding an input sequence by using a low-density parity-check (LDPC) matrix, to obtain a bit sequence D, where a base matrix of the LDPC matrix is represented as a matrix of m rows and n columns, each column corresponds to a group of Z consecutive bits in the bit sequence D, and n and Z are both integers greater than 0; and obtaining an output bit sequence based on a bit sequence V, where the bit sequence V is obtained by permuting two groups of bits corresponding to at least two parity check columns in the bit sequence D.

Abstract: This application discloses a data transmission method, a sending device, a receiving device, and a communications system. The sending device is configured to send a first transport block. The sending device obtains a coded bit segment from a first encoded code block. The first encoded code block is obtained after LDPC encoding is performed on a first code block in the first transport block based on a processing capability of the receiving device. The sending device sends the coded bit segment to the receiving device. Because the processing capability of the receiving device is considered, storage overheads of the sending device or the receiving device can be reduced, encoding or decoding complexity can be reduced, and a decoding success rate can be improved.
