1. A method of wireless communication operable at a subordinate entity, the method comprising:
communicating with a scheduling entity utilizing a plurality of subframes comprising a first subframe and a second subframe, each of the subframes comprising an uplink (UL) portion and a downlink (DL) portion;
receiving DL control information (DCI) from the scheduling entity in the DL portion of the first subframe; and
transmitting, to the scheduling entity, a first UL transmission comprising a burst structure including a plurality of reference signal bursts distributed in time in the UL portion of the first subframe based on the DCI, each of the plurality of reference signal bursts being transmitted using different precoding in a different time slot of the UL portion of the first subframe,
the plurality of reference signal bursts being transmitted using a different subset of antennas of the subordinate entity for each of the plurality of reference signal bursts, one or more of the plurality of reference signal bursts being transmitted using a first subset of the antennas, one or more of the reference signal bursts being transmitted using a second subset of the antennas,
wherein the burst structure comprises a greater number of reference signal bursts than a nominal number of reference signal bursts transmitted in the second subframe.
