Precoding diversity in time domain

Abstract

Systems and methods for enabling precoding diversity in the time domain are provided. In some embodiments, a User Equipment (UE) includes circuitry including a processing module and a memory module configured to receive an indication that a physical channel is repeated over a set of subframes and receive an indication that the UE can assume that a first subset of the repetitions of the physical channel and a reference signal will use a first precoder. In this way, in some embodiments, the UE can coherently combine the repetitions, including the reference signals used by the physical channel. The ability to coherently combine repetitions of the physical channel may improve both the estimates of the physical channel as well as channel estimates derived from the repeated reference signals.

What is claimed is: 
     
         1 . A User Equipment, UE, comprising:
 circuitry comprising a processing module and a memory module configured to:
 receive an indication that a physical channel is repeated over a set of subframes; and 
 receive an indication that the UE can assume that a first subset of the repetitions of the physical channel and a reference signal will use a first precoder.
