Abstract
Certain aspects of the present disclosure relate to techniques and apparatus for enabling non-destaggered channel estimation. In aspects, a method for wireless communications is provided including determining a first channel impulse response (CIR) based on a first set of received reference signals staggered in time, determining a second CIR based on a second set of received reference signals from the same sub-frame time slot, wherein a reference signal is associated with one of a plurality of virtual transmit antenna ports, and aligning the first CIR and the second CIR based, at least in part, on a time tracking loop (TTL) timing offset.
