Technology for a user equipment (UE) to communicate in a multiple radio access technology (multi-RAT) heterogeneous network (HetNet) is described. A radio-link-selection hysteresis threshold can be determined at the UE for a radio link between the UE and a node in the multi-RAT HetNet. A reliability value of a throughput estimate can be measured for the radio link in the multi-RAT HetNet. The radio-link-selection hysteresis threshold can be adjusted at the UE based on the reliability value to increase network stability in the multi-RAT HetNet.
