1. An apparatus configured for wireless communication utilizing a time-division duplex (TDD) carrier comprising a plurality of TDD subframes, the apparatus comprising:a transceiver;
a memory; and
at least one processor communicatively coupled to the transceiver and the memory, wherein the at least one processor is configured to:
utilize the transceiver to receive signaling comprising information configured to indicate whether to adjust a structure of a TDD subframe; and
if the information indicates adjusting the structure of the TDD subframe, adjust the structure of the TDD subframe in response to receiving the signaling;
wherein adjusting the structure of the TDD subframe comprises adjusting a time or subcarrier allocated for one or more reference signals communicated in the TDD subframe;
wherein adjusting the structure of the TDD subframe further comprises adjusting a time at which the one or more reference signals are communicated to be aligned with a time at which a demodulation reference signal (DMRS) of another TDD subframe is communicated by another apparatus.
