Abstract
A method for sending configuration information is performed by a base station and includes sending the configuration information to a terminal. The configuration information indicates a configuration of a plurality of beams, and the plurality of beams are used for a satellite to communicate with the terminal. A method for receiving configuration information is performed by a terminal and includes receiving the configuration information sent by a base station. The method also includes determining a configuration of a plurality of beams based on the configuration information.
Claims18
A method for sending configuration information, performed by a base station communicating with a terminal over a non-terrestrial network, comprising:
- sending the configuration information to the terminal, wherein the configuration information indicates a configuration of a plurality of beams used for a satellite to communicate with the terminal;
- wherein the configuration information comprises timing offset information between a reference beam and a non-reference beam in the plurality of beams, the timing offset information represents a duration between a moment when the terminal receives a signal through the reference beam and a moment when the terminal receives a signal through the non-reference beam, and the timing offset information and a time delay of the satellite transmitting the signal through the reference beam are used to determine a time delay of the satellite transmitting the signal through the non-reference beam;
- wherein the method further comprises:
- receiving request information sent by the terminal, wherein the terminal is configured to send the request information to the base station in response to determining that a relationship between transmission durations corresponding to the reference beam and the non-reference beam in a process of transmitting the signal from the satellite to the terminal satisfies a preset relationship;
- and
- sending update information for updating the timing offset information to the terminal.

- wherein the method further comprises:
- measuring transmission durations corresponding to the reference beam and the non-reference beam in a process of transmitting the signal from the satellite to the terminal in response to determining that the satellite communicates with the terminal via the reference beam and the non-reference beam;
- sending request information to the base station in response to determining that a relationship between the transmission durations corresponding to the reference beam and the non-reference beam satisfies a preset relationship;
- and
- receiving update information for updating the timing offset information sent by the base station based on the request information.
