Title:

A method and a device for channel estimation

Document Type and Number:

Japanese Patent JP6204926

Kind Code:

B2

Abstract:

Some embodiments provide a method in a network node. The network node obtains (1110) an indication that a set of antenna ports or reference signal ports share at least one channel property; transmits (1120) signals corresponding to at least two of the antenna ports or reference signal ports in the set; and transmits (1130) an indication of the set of antenna ports or reference signal ports to at least one wireless device served by the network node.
