Abstract: A communication method and apparatus is provided. The method includes: camping on a first cell by a terminal device. The method further includes: determining, by the terminal device, to access a second cell in response to: receiving a paging message from the first cell, determining that there is to-be-transmitted uplink information, or determining that there is a to-be-transmitted non-multicast service. A frequency of the first cell is different from a frequency of the second cell. The terminal device may not perform uplink transmission or may receive only a multicast service in the first cell so that energy consumption of cell measurement and beam selection is reduced.
