SIGNAL TRANSMISSION METHOD, NETWORK DEVICE, AND TERMINAL DEVICE
First Claim
1. A signal transmission method, comprising:
- 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.

Abstract
The present disclosure relates to signal transmission methods, network devices, and terminal devices. One example method includes sending, by a network device, N first reference signals to a terminal device, where N is a positive integer greater than or equal to 1, sending, by the network device, physical layer control signaling to the terminal device, where the physical layer control signaling is used to trigger the terminal device to send a channel quality measurement result of the N first reference signals to the network device, and is used to instruct the terminal device to send M second reference signals to the network device, and M is a positive integer greater than or equal to 1, receiving, by the network device, the channel quality measurement result from the terminal device, and receiving, by the network device, the M second reference signals from the terminal device.
