1. A method for power control, comprising:
sending, by a second node, a reference signal to a first node;
determining, by the first node, a transmit power dynamic range of the second node based on the reference signal; the transmit power dynamic range is used for spatial multiplexing transmission; and;
sending, by the first node, the transmit power dynamic range of the second node to the second node; and;
determining, by the second node, a transmit power according to the transmit power dynamic range; wherein: the second node is an upper-level node of the first node.
