Abstract
Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a second UE, and a processor communicatively coupled to the transceiver. The processor is configured to determine a set of subcarriers from two physical resource blocks (PRBs). The set of subcarriers includes only one subcarrier or more than two subcarriers. The processor is further configured to transmit, using the first set of antenna ports of the transceiver, channel state information reference signals (CSI-RSs) in a set of resource elements (REs) to the second UE. The set of REs occupies the set of subcarriers.
