1. A method of performing communications, the method comprising:

  • providing, by a network element, a first reference signal configuration corresponding to one or more first user equipments (UEs), wherein the first reference signal configuration comprises a first Channel Status Indication-Reference Signal (CSI-RS) configuration;

    providing, by the network element, a second reference signal configuration corresponding to the one or more first UEs, wherein the second reference signal configuration comprises a second CSI-RS configuration different from the first CSI-RS configuration,wherein the first reference signal configuration comprises an indication of a first scrambling code and an indication of a first time-frequency resource to the one or more first UEs, wherein the second reference signal configuration comprises an indication of a second scrambling code and an indication of a second time-frequency resource to the one or more first UEs, wherein the first scrambling code is different than the second scrambling code, and wherein the first time-frequency resource is different than the second time-frequency resource;

    transmitting, by an antenna of the network element using dedicated signaling, the first reference signal configuration to the one or more first UEs; and

    transmitting, by the antenna of the network element using dedicated signaling, the second reference signal configuration to the one or more first UEs, wherein the first CSI-RS configuration and the second CSI-RS configuration are different from another CSI-RS configuration transmitted by the antenna of the network element to another UE.
