Abstract: A method for operating an access node includes sending a configuration of one or more first channel state information reference signal (CSI-RS) resources and a configuration of one or more sounding reference signal (SRS) resources, generating first control information including an identifier of a SRS resource set that includes the one or more SRS resources precoded by one or more precoders, generating second control information including an identifier of the one or more first CSI-RS resources, wherein the one or more first CSI-RS resources are associated with the identified SRS resource set, wherein the one or more first CSI-RS resources convey a downlink reference signal (RS) used for making measurements, and wherein the one or more precoders are determined in accordance with measurements of the downlink RS, sending the first control information and the second control information, and sending the downlink RS.
