Methods and apparatus for processing control and/or shared channels in long term evolution (LTE)
First Claim
1. A method for wireless communications, comprising:
- receiving a control channel and a shared channel within a subframe;
determining that one or more channel properties of the control channel and the shared channel in the received subframe are substantially the same,wherein the one or more channel properties comprise at least one of a delay spread, a receive power, a frequency shift, a Doppler spread, or a receiver timing, andwherein the determining is based on a radio resource control (RRC)-configured resource set associated with the control channel;
determining that the control channel and the shared channel are quasi co-located based on the determination that one or more channel properties of the control channel and the shared channel are substantially the same; and
processing the control channel and the shared channel based on the determination that the control channel and the shared channel are quasi co-located.

Abstract
Certain aspects provide methods and apparatus for processing a control channel and/or a shared channel in a subframe based on a determination that one or more channel properties of the two channels are substantially the same. One example method generally includes receiving a control channel and a shared channel within a subframe; determining that one or more channel properties of the control channel and the shared channel in the subframe are substantially the same; and processing the control channel and the shared channel based on the determination. In this manner, estimations determined for a first channel may be assumed for a second channel whose channel properties are substantially the same as the first channel, rather than by separately determining the estimations for the second channel, thereby saving processing time.
