Method for communicating in a network

A secondary station comprising:

• a receiver configured to receive, from the primary station, coefficients used in post processing,
• a controller configured to select a first communication scheme from a plurality of communication schemes,
• the controller being configured to derive post-processing coefficients based on the characteristics of the first communication scheme and the observed channel between the transmit antennas and the receive antennas,
• the controller being configured to estimate a combined channel based on an observed channel between the plurality of transmit antennas and the plurality of receive antennas, and the results of the post-processing using said post processing coefficients
• the controller being configured to assemble a CSI (Channel State Information) report assuming characteristics of a second communication scheme and according to the estimated combined channel and,
• a transmitter configured to transmit the CSI report to the primary station.

A method for operating a secondary station in a network comprising a primary station and at least one secondary station, the primary station comprising a plurality of transmit antennas and the secondary station comprising a plurality of receive antennas, the method comprising:

• selecting by a controller of the secondary station, a first communication scheme from among a plurality of communication schemes,
• using a controller to derive post-processing coefficients based on the characteristics of the first communication scheme and the observed channel between the transmit antennas and the receive antennas,
• using the controller to estimate a combined channel based on an observed channel between the plurality of transmit antennas and the plurality of receive antennas, and the results of the post-processing using said post processing coefficients
• using the controller to assemble a CSI (Channel State Information) report assuming characteristics of a second communication scheme and according to the estimated combined channel and
• transmitting via a transmitter of the secondary station, the CSI report to the primary station.
