Method, device and system for signalling transmission of virtual multi-antenna system

摘要

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).

1. A method for signalling transmission in a virtual multi-antenna system, comprising:
receiving, by L terminal(s), channel related information from one terminal in M terminal(s), and calculating comprehensive Channel State Information (CSI) according to the channel related information; and feeding back, by the L terminal(s), the comprehensive CSI to a Node B, or forwarding, by the L terminal(s), the comprehensive CSI to one terminal in N terminals, and feeding back, by the one terminal in the N terminals, the comprehensive CSI to the Node B; wherein L is smaller than or equal to N and larger than or equal to 1, M is smaller than or equal to N and larger than or equal to 1, the M terminal(s) form(s) a subset of the N terminals, the N terminals are configured to receive Channel State Information Reference Signals (CSI-RSs) from the Node B, and N is a positive integer larger than or equal to 2; wherein when the L terminal(s) are/is terminal(s) except the N terminals and L is equal to 1, the one terminal except the N terminals receives the channel related information from the M terminal(s); wherein the one terminal except in the N terminals is a centralized processing device not connected to a current mobile communication network.
