摘要： A method for an electronic device includes determining, based on indicating information of an uplink pilot sequence allocated by a base station, an uplink pilot sequence, transmitting the uplink pilot sequence, and determining a change in a geographical location of the electronic device. In a case that the geographical locations of the electronic device before and after changing correspond to different cell partitions, the uplink pilot sequence is updated based on the indicating information allocated by the base station, and the updated uplink pilot sequence corresponds to the cell partition corresponding to the geographical location of the electronic device after changing. The uplink pilot sequence is for the base station estimating a channel between the base station and the electronic device, and filtering based on the geographical location of the electronic device during the channel estimation, to obtain a channel estimation result matching the electronic device.
