Abstract  Abstract

Disclosed in some examples are methods, systems, devices, and machine readable mediums which reduce the amount of bandwidth consumed by the reference signals. In some examples, this is achieved by finding the optimal subspace containing all the active UEs in the cell and transmitting reference signals to that subspace. In some examples, second order statistics may be utilized to calculate a projected channel to the optimal subspace at the UE and then feeding this back to the eNodeB. The projected channel to optimal subspace may be utilized at the UE and the eNodeB to transform the codebook and align the codewords with the channel direction.
