Abstract: 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.

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.
