1. A communication method performed by a terminal device or a chip system of the terminal device, wherein the method comprises:
when detecting a link problem occurs in a master cell group (MCG) or a signal quality of the MCG is less than a signal quality threshold,
resuming a secondary cell group (SCG) that is suspended before detecting the link problem occurs in the MCG or the signal quality of the MCG is less than the signal quality threshold, wherein the resuming comprises: determining that a maximum transmit power used by the terminal device to send a signal to the SCG is a first maximum transmit power, wherein the first maximum transmit power is greater than a second maximum transmit power that is a maximum transmit power used by the terminal device to send a signal to the SCG before the SCG is suspended;
the MCG being managed by a master node, and the SCG being managed by a secondary node.
