1. A baseband processor configured to cause a user equipment (UE) to:
determine:
a first number of reference signal resources that the UE supports during an amount of time for one or more of new beam identification or path loss measurement;
whether the UE supports 2 port channel state information reference signal (CSI-RS) for the new beam identification with the first number of reference signal resources; and
whether the UE supports multi-port CSI-RS processing for the path loss measurement with the first number of reference signal resources;
transmit, to a base station:
an indication of the first number of reference signal resources;
an indication of the support of 2 port CSI-RS for the new beam identification; and
an indication of the support of multi-port CSI-RS for the path loss measurement;
receive, from the base station, a 2 port CSI-RS; and
perform one or more of the new beam identification or path loss measurement based on the 2 port CSI-RS.
