Abstract: Example beam hopping methods and apparatus are described. In one example method, a first satellite sends a communication signal to a first area by using a first beam, where the communication signal is used by the first satellite to communicate with a terminal device in the first area, and the first area belongs to an area covered by the first satellite. The first satellite sends a positioning signal to a second area by using a second beam, where the positioning signal is used by a terminal device in the second area for positioning measurement.

Abstract: This application provides an uplink timing method. A half-duplex terminal device determines, based on a maximum timing advance of an area in which the terminal device is located and a set of time units used by the terminal device to receive a system message, a set of time units unavailable for uplink transmission, and in a process of calculating a time unit for sending an uplink signal, skips, based on a scheduling offset of the uplink signal, a time unit in the set of time units unavailable for uplink transmission, to avoid a problem that the half-duplex device needs to simultaneously perform receiving and sending in a large transmission latency scenario.

Abstract: The present disclosure relates to access methods and apparatuses. In one example method, a terminal device determines, based on whether a first frequency offset parameter is in a frequency offset parameter range, whether to access a first cell. If the first frequency offset parameter is in the frequency offset parameter range, a current location of the terminal device is not at an edge of the cell. Otherwise, the current location of the terminal device may be at the edge of the cell.
