Abstract: Embodiments of the application provide a method for transmitting data in a wireless communication network. A device of the network receives a bit sequence of K information bits. The device polar codes the bit sequence to obtain a first encoded sequence, wherein a length of the first encoded sequence is N, and N is greater than or equal to K. The device block interleaves the first encoded sequence to obtain an interleaved bit sequence. The device determines a transmission code rate R. When the transmission code rate R is less than the code rate threshold, the device outputs a second bit sequence. The length of the second bit sequence is M, M is smaller than N. The second bit sequence is punctured from the interleaved bit sequence by removing (N−M) bits from beginning of the interleaved bit sequence.

Abstract: Embodiments of the application provide a method for rate matching in a wireless communication network. A device obtains K information bits and a target code length M of a polar code, determines, according to a minimum value of a set of values, a mother code length N1, polar encodes the K information bits to obtain an encoded sequence of N1 bits, obtains a target sequence of M bits from the N1 bit encoded sequence, and outputs the M-bit target sequence. When the mother code length N1 is larger than the target code length M, (N1−M) bits of the encoded sequence are punctured or shortened from the N1 bit encoded sequence.

Abstract: This application provides a TA determining method and apparatus for a terminal device. After receiving a TA adjustment parameter sent by an access network device and determining that a TA of the terminal device needs to be adjusted, the terminal device determines a TA scaling factor, a subcarrier spacing parameter, and a first TA, to jointly adjust the first TA to obtain a second TA. ATA adjustment parameter k is added when the terminal device determines the second TA, so that an adjustable range of the TA is larger. Therefore, the TA may be applied to determining the TA of the terminal device when the terminal device communicates with a satellite base station. In this way, the terminal device can adjust the TA when movement of a device is caused by both the terminal device and the satellite base station.

Abstract: A network verification system obtains configuration data of a plurality of network devices, where a data model of the configuration data is described by using a general data modeling language independent of the network devices; and the network verification system verifies data links between the plurality of network devices based on the configuration data of the plurality of network devices and a topology structure between the plurality of network devices. The network verification system verifies the data links between the plurality of network devices based on the topology structure between the plurality of network devices and the configuration data described by using the general data modeling language independent of the network devices. This helps improve scalability of the network verification system and avoids relatively poor scalability of network simulation software that occurs when conventional network simulation software provides a template for configuration data of each type of network device.
