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. After that, 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 relates to communicating information between communication devices. A channel coding method is disclosed. A communication device obtains an input sequence of K bits. The communication device encodes the input sequence using a low density parity check (LDPC) matrix H, to obtain an encoded sequence. The LDPC matrix H is determined according to a base matrix and a lifting factor Z. The base matrix includes m rows and n columns, m is greater than or equal to 5, and n is greater than or equal to 27. The lifting factor Z satisfies a relationship of 22*Z≥K. According to the encoding method provided in the embodiments, information bit sequences of a plurality of lengths can be encoded for transmission between the communication devices.
