Claim:
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 the secondary pilot channel transmitted by a network node; processing the received CQI values, including storing the received CQI values; and deciding based on the stored CQI values which network node(s) in the heterogeneous network to select for serving the UE, wherein the deciding comprises comparing the received and stored CQI values with a CQI threshold and selecting the network node(s) associated with the CQI value having a value higher than the CQI threshold.
