Beam procedure information for channel state information reference signals (csi-rs)

A method for wireless communication by a base station, comprising:

• deciding which transmit beams to use for transmitting reference signal (RS) resources to a user equipment (UE) as part of a beam refinement procedure;
• providing information to the UE indicating which RS resources are to be transmitted by the base station using a same transmit beam or a same set of transmit beams;
• and
• transmitting the RS resources in accordance with the decision.

An apparatus for wireless communication by a user equipment (UE), comprising:

• means for obtaining information regarding a beam refinement procedure that involves a set of reference signal (RS) resources for transmitting RS, the information indicating which RS resources are to be transmitted by a base station using a same transmit beam or a same set of transmit beams;
• means for deciding, based on the information, which receive beam or set of receive beams to use for reception of the RS resources transmitted by the base station;
• and
• means for receiving the RS resources in accordance with the decision.
