Abstract: This application describes methods, systems, and techniques for performing communication based on a beam group. In a method, for example, a terminal device groups transmit beams of a network device based on a receive beam of the terminal device. The method may also include the terminal device determining spatial direction information of each beam group. Furthermore, the method may include the terminal device sending, to the network device, the spatial direction information of each beam group or information about a correlation between beam groups determined based on the spatial direction information.

Abstract: An embodiment of this application provides a power control method. The method includes: receiving, by a first node from a second node, first power control information associated with a first resource pair link; and sending, by the first node, a first signal to the second node by using a first transmission resource corresponding to the first resource pair link, where transmit power of the first signal is obtained based on the first power control information. An association relationship is established between power control and a resource pair link, so that power control on a resource pair link granularity can be implemented, different power control can be performed based on different channel features, and more accurate transmit power is obtained. In addition, various signals are transmitted on resources corresponding to different resource pair links, so that different power control values can be set for the various signals. In this way, interference can be reduced while correct reception is performed, and a significant gain may be made on network communication quality.
