摘要： A method in a network node for sending a pilot power value in a heterogeneous mobile communications network. The heterogeneous mobile communications network comprises a second set of base station nodes selected to operate in a Multiple Input Multiple Output, MIMO, -mode. The second set of base station nodes share a cell identity and are deployed within a coverage area. The network node computes (802) a pilot power value to be applicable when one or more mobile devices in the coverage area evaluates receipt of one or more Secondary Common Pilot Channels, S-CPICH, from a transmitter in said second set of base station nodes, wherein the computing is based on a measure indicative of a transmission power of the second set of base stations. The network node sends a signal to a radio network controller. The signal comprises the computed pilot power value, and enables the one or more mobile devices to be configured for MIMO operation.
