1. A method in a controller node for selecting for a user equipment, UE, at least one network node in a heterogeneous network comprising a plurality of network nodes each network node transmitting a primary pilot channel and a secondary pilot channel, the method comprising:
receiving from the UE, channel quality indicator, CQI, values, each CQI value corresponding to a channel estimate estimated by the UE on individual secondary pilot channel transmitted by a network node; processing the received CQI values; and deciding based on the processed CQI values which network node(s) in the heterogeneous network to select for serving the UE.
