摘要： A terminal device obtains first indication information, where the first indication information indicates an ephemeris parameter of a first satellite at a first moment. The terminal device determines a position and a velocity of the first satellite at a second moment based on the ephemeris parameter of the first satellite at the first moment, where the second moment is after the first moment. In response to determining that an error of the position of the first satellite at the second moment is less than a first threshold and an error of the velocity of the first satellite at the second moment is less than a second threshold, the terminal device obtains second indication information, where the second indication information indicates an ephemeris parameter of the first satellite at a third moment, and the third moment is before the second moment.

摘要： A power module is provided. The power module includes a substrate, and the substrate is used to carry components and pins of the power module. A circuit layer is disposed on the substrate, to complete an electrical connection between the carried components. The components and the pins are disposed on a same surface of the substrate, and the components and the pins are electrically connected by using the substrate. The power module further includes a sealing layer. The sealing layer is sleeved on the pins, the pins are partially exposed on a surface that is of the sealing layer and that faces away from a plastic packaging layer, and a space for accommodating the plastic packaging layer is formed between the sealing layer and the substrate.

The method includes: obtaining A to-be-encoded information bits; mapping the A to-be-encoded information bits and L CRC bits to a first bit sequence based on an interleaving sequence, where the L CRC bits are obtained based on the A to-be-encoded information bits and a CRC polynomial, the interleaving sequence is obtained from a prestored interleaving sequence table or is obtained based on a maximum-length interleaving sequence, A+L is less than or equal to Kmax, and Kmax is a length of the maximum-length interleaving sequence; and encoding the first bit sequence. In this way, not only an encoding delay can be reduced, but also decoding has an early stop capability, so that decoding can end in advance, thereby reducing a decoding delay.

The method includes: A terminal receives indication information from an access network device, where the indication information is used to determine whether HARQ feedback is needed for a transmit block transmitted in a plurality of downlink transmission units. The terminal determines HARQ bitmap information based on the indication information, where the HARQ bitmap information includes HARQ feedback information of at least one target transmission unit, and the target transmission unit indicates a downlink transmission unit that needs HARQ feedback in the plurality of downlink transmission units. The terminal sends the HARQ bitmap information to the access network device. Some embodiments of the present disclosure can reduce feedback resource overheads in an NTN scenario, reduce a communication delay, and improve a communication throughput rate.
