摘要：
A method in a network node for estimating a channel from a user node to the network node is provided. The network node receives first pilots. The network node receives (502) additional pilots from the user node. The network node estimates (503) the channel based on the additional pilots. The additional pilots are any one out of: pilots in an existing channel, modified to create space for the additional pilots, and an existing mechanism modified to be used as the additional pilots.
