Abstract
Disclosed are a method, device and system for signalling transmission in a virtual multi-antenna system. The method includes N terminals receive CSI-RSs from a Node B, N being a positive integer larger than or equal to 2; and one terminal in M terminal(s) calculates channel related information from the Node B to the terminal according to the received CSI-RS, and sends the channel related information to L terminal(s), wherein the M terminal(s) form(s) a subset of the N terminals, M is smaller than or equal to N and larger than or equal to 1, and L is smaller than or equal to N and larger than or equal to 1. A first sending unit in the device is configured to calculate channel related information from a Node B to one terminal in M terminal(s) according to a CSI-RS received by the terminal, and send the channel related information to L terminal(s).
