A method and apparatus is provided, where a respective reference signal associated with each of one or more downlink transmit antenna ports in a wireless communication network is received. A value is determined for each of one or more measurable characteristics relative to each of the received reference signals. One or more parameters are received, the parameters including one or more adjustments, where each adjustment is specific to one of the downlink transmit antenna ports and include adjustments in the form of one or more respective offset values to be applied to at least some of the one or more determined values of the measurable characteristics of the received reference signals. At least one downlink transmit antenna port is then to function as a serving downlink transmit antenna port for the user equipment, based upon a comparison of the resulting values of the measurable characteristics of the received reference signals after the received one or more adjustments have been applied to the corresponding determined values.
