    Abstract: Embodiments of this application provide a method and an apparatus for constructing a coding sequence. The method includes: storing a reliability sequence corresponding to a basic sequence, where a length of the reliability sequence corresponding to the basic sequence is less than or equal to a length of a reliability sequence corresponding to a mother code sequence; storing a reliability reference sequence, where the reliability reference sequence includes at least one element remaining after the reliability sequence corresponding to the basic sequence is excluded from the reliability sequence corresponding to the mother code sequence; and constructing a coding sequence by using the reliability sequence corresponding to the basic sequence and an element in the reliability reference sequence. During implementation of this application, during storage, only the reliability sequence corresponding to the basic sequence and the reliability reference sequence are stored. Because a sum of the length of the reliability sequence corresponding to the basic sequence and a length of the reliability reference sequence is far less than the length of the original reliability sequence, storage overheads can be reduced.

    Abstract: Embodiments provide a Polar code transmission method and apparatus. A bit sequence is encoded into a code sequence using Polar code by a network device. The bit sequence contains a control signaling and a Cyclic Redundancy Code (CRC) sequence. The code sequence is transformed into M copies such that an ith information copy of the M copies multiples by a first matrix of the power of (i−1). M is an integer and M>0. M copies of codeword was encoded by Polar code, the M copies implicitly conveys different time stamp information, which is suitable for the transmission of PBCH in 5G communication system, signaling overhead is also reduced.

    Abstract: This application provides a resource configuration method and a related apparatus. The method includes: A first terminal device receives first configuration information used to configure a first time division duplex frame structure. Because an interval between adjacent uplink time domain resources in the first time division duplex frame structure is determined based on a largest timing advance and a smallest timing advance in a terminal device that uses the first time division duplex frame structure, and the terminal device that uses the first time division duplex frame structure includes the first terminal device, after the first terminal device sends uplink data on a first uplink time domain resource in the first time division duplex frame structure by using a first timing advance, when the uplink data arrives at a network device, a time domain resource that can be used by the network device is an uplink time domain resource.

    Abstract: A communication method and apparatus are provided to reduce interference between different types of satellites. The method is: A terminal device determines a satellite type corresponding to a first area, and the terminal device determines, based on the satellite type, whether to access a network device covering the first area. The terminal device determines, based on the determined satellite type corresponding to the first area, whether the network device can be accessed, so that a type of the network device accessed by the terminal device is consistent with the satellite type of the first area, and the terminal device can access only one type of satellite. When a plurality of types of satellites reuse a same frequency, the terminal device may receive signals of the plurality of types of satellites in the first area.
