Signal transmission method, terminal device and network device

A signal transmission method, comprising:

• receiving, by a terminal device, beam indication information sent by a network device, wherein the beam indication information indicates whether or not a same beam is adopted for sending N Channel State Information-Reference Signals (CSI-RSs) on N CSI-RS resources from the network device, and N is an integer greater than 1;
• and
• receiving, by the terminal device, according to the beam indication information, the N CSI-RSs sent on the N CSI-RS resources from the network device;
• wherein the beam indication information indicates that the N CSI-RSs are sent to the terminal device using at least two different beams, and the method further comprises:
• sending, by the terminal device, first indication information to the network device, the first indication information indicating K signals out of the N CSI-RSs, wherein 1≤K<N, and K being an integer.
