Abstract

A heterogeneous wireless communication network includes a macrocell base station that one or more low power nodes. The location of a wireless device is estimated based on feedback reports received from the wireless device in response to downlink transmissions of a reference signal. Based on the estimated location, a schedule for future transmissions of the reference signal to the wireless device are determined. The schedule specifies a frequency of transmission of the reference signals. The schedule specifies downlink transmission antenna configuration to be used for the reference signal transmissions.
