  • receiving, by a terminal device and from a network device, an indication information, wherein the indication information is used to indicate an association between transmitting M second reference signals and a resource index of a first reference signal, wherein the first reference signal is sent by the network device to the terminal device, wherein M is a positive integer greater than or equal to 1, and wherein according to the association, a formed transmit beam for the M second reference signals is the same as a formed receive beam for the first reference signal;

    receiving, by the terminal device, physical layer control signaling and from the network device, wherein the physical layer control signaling is used to indicate the terminal device transmitting one or more second reference signal to the network device; and

    transmitting, by the terminal device, one or more second reference signal to the network device.
