Document Type and Number:
WIPO Patent Application WO/2013/134462
Kind Code:
A3
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.
