Various communication systems may benefit from joint precoder and receiver designs for multi-user multiple-input and multiple-output. For example, machine-type communication in long term evolution communication systems may benefit from such designs. A method can include determining channel status information of a current connection. The method can also include indicating the channel status information to a transmitter. The method can further include receiving weight values for a first receiver filter, in response to the channel status information. The method can also include defining the first receiver filter based on the weight values. The method can further include determining effective channel status information of a current connection, and interference from other transmitters. The method can also include defining a second receiver filter based on the weight values, the effective channel status information of the current connection, and the interference.
