    Abstract: This application relates to the field of communication technologies, and discloses an encoding method, a decoding method, and an apparatus. The method includes: obtaining an information bit sequence; and encoding the information bit sequence based on a systematic polar code, to determine an encoded bit sequence, where the systematic polar code includes N first bit positions and N second bit positions that correspond to a polarization transformation matrix, the N second bit positions include a systematic bit position set A and a non-systematic bit position set MA, the N first bit positions include a frozen bit position set B and a non-frozen bit position set MB, and A is determined based on the information bit sequence.

    Abstract: A method includes: A transmit end obtains P QAM symbols; the transmit end performs IDWT or DWT on the P QAM symbols, to obtain a first signal matrix with N rows and M columns, and transposes the first signal matrix, to obtain a transposed first transpose matrix, where P, N, and M are all positive integers; and the transmit end outputs the transposed first transpose matrix. Correspondingly, a receive end obtains a second signal matrix with M rows and N columns; the receive end transposes the second signal matrix, to obtain a transposed second transpose matrix; and performs DWT or IDWT on the second transpose matrix, to obtain P QAM symbols.

    Abstract: A satellite communication method and an apparatus are provided, and the method may be applied to a communication apparatus supporting a satellite frequency band, a communication apparatus supporting the satellite frequency band and a terrestrial frequency band, or the like. The method includes: A first communication apparatus obtains a first signal threshold, and detects a signal strength of a second frequency band, where the second frequency band is used by a second communication apparatus (for example, a communication apparatus in a terrestrial cell) to receive a signal; and when the signal strength of the second frequency band is less than or equal to the first signal threshold, determines to send a signal on a first frequency band.

    Abstract: An encoding method and apparatus are provided, to propose a construction and encoding scheme of a BCH code. A code length and a code rate of an obtained BCH code are flexible, to satisfy a requirement of flexible channel encoding in wireless communication. The method includes determining a first encoding parameter based on a first BCH code, where the first BCH code is a to-be-coded BCH code, the first encoding parameter is a first code or a generator matrix of a first code, the first code has a code length of n and an information bit length of k, n is greater than 0, and k is greater than 0, and performing BCH encoding based on the first encoding parameter.

    Abstract: A first communication apparatus obtains first indication information in a first slot, where the first indication information indicates the first communication apparatus to switch from an uplink transmission bandwidth to a first transmission bandwidth; then, the first communication apparatus determines a second slot based on the first slot and a first switching delay, where the first switching delay is determined based on a first timing offset value, and the first timing offset value is determined based on a round-trip delay between a first location in an area covered by a second communication apparatus and the second communication apparatus; and the first communication apparatus sends uplink information to the second communication apparatus by using the first transmission bandwidth from the second slot.
