Measurement of nodes in coordinated multipoint (CoMP) systems
Abstract:
Technology for enabling radio resource management (RRM) measurements in coordinated multi-point (CoMP) transmission and reception is disclosed. One method comprises sending, from an evolved node B (eNB) to a user equipment (UE), an information element (IE) containing a list of measurement objects that define configurations of channel state information reference signal (CSI-RS) based RRM measurements. The eNB can analyze the CSI-RS based RRM measurements in a CoMP Resource Management (CRM) Set, wherein each CSI-RS based RRM measurement corresponds to a transmission point in a set of transmission points which may be used for downlink transmissions to the UE. The eNB can select a CoMP Measurement Set based on the CSI-RS based RRM measurements reported by the UE, comprising at least one of the set of transmission points for which fast channel state information (CSI) feedback will be reported to the eNB from the UE.
