1. A communication method, comprising:
receiving a deactivation indication from an access network device, wherein the deactivation indication indicates that a primary secondary cell in a secondary cell group is in a deactivated state, wherein the access network device comprises a master node or a secondary node of a terminal, wherein in response to the access network device comprising the master node, the master node manages a master cell group used in data communication between the terminal and the master node, wherein in response to the access network device comprising the secondary node, the secondary node manages the secondary cell group used in data communication between the terminal and the secondary node, and wherein each of the master node and the secondary node is configured to determine to deactivate the primary secondary cell in the secondary cell group, and in response to the master node determining to deactivate the primary secondary cell, the master node is configured to send the deactivation indication to the terminal, or in response to the secondary node determining to deactivate the primary secondary cell, the secondary node is configured to send the deactivation indication to the terminal;
performing a deactivation operation on the secondary cell group according to the deactivation indication, wherein the deactivation operation on the secondary cell group according to the deactivation indication comprises retaining a configuration of the secondary cell group; and
performing radio resource measurement on the primary secondary cell by using the primary secondary cell in the deactivated state as a serving cell or a neighbor cell of a serving cell.
