1. A method for cell measurement, comprising:
obtaining, by a terminal device, a target start time of a Synchronization signal Block Measurement Timing Configuration (SMTC) and/or a target start time of a measurement gap for a cell list; and
measuring, by the terminal device, at least one cell in the cell list based on the target start time of the SMTC and/or the target start time of the measurement gap,
wherein the obtaining, by the terminal device, the target start time of the SMTC and/or the target start time of the measurement gap for the cell list, comprises:
determining, by the terminal device, the cell list; and
determining, by the terminal device, the target start time of the SMTC and/or the target start time of the measurement gap,
wherein the determining, by the terminal device, the target start time of the SMTC and/or the target start time of the measurement gap, comprises:
determining, by the terminal device, a first difference, wherein the first difference is a difference between a signal transmission delay between the terminal device and a base station of a first cell and a signal transmission delay between the terminal device and a base station of a serving cell; and
determining, by the terminal device, the target start time of the SMTC and/or the target start time of the measurement gap for measuring the first cell according to the first difference, wherein the cell list comprises the first cell,
wherein the determining, by the terminal device, the target start time of the SMTC and/or the target start time of the measurement gap for measuring the first cell according to the first difference, comprises:
determining, by the terminal device, an offset according to the first difference; and
determining, by the terminal device, the target start time of the measurement gap for measuring the first cell according to a basic start time of the measurement gap and the offset, and/or determining, by the terminal device, the target start time of the SMTC for measuring the first cell according to a basic start time of the SMTC and the offset, wherein one or more of the following:
the target start time of the measurement gap is a sum of the basic start time of the measurement gap and the offset;
the target start time of the SMTC is a sum of the basic start time of the SMTC and the offset.
