1. A method for operating a wireless communication device, the method comprising:
receiving capability information relating to a further wireless communication device, the capability information indicating that the further communication device is restricted to non-coherent transmissions,
receiving, from the further wireless communication device, a plurality of reference signals at an antenna port of the wireless communication device,
determining a channel estimate based on the received plurality of reference signals,
selecting a precoder from a second set of precoders based on the determined channel estimate, wherein the second set of precoders comprises at least one precoder in addition to precoders of a first set of precoders assigned for use by the further wireless communication device in sending the plurality of reference signals, and
sending an indication relating to the selected precoder to a further wireless communication device from which the reference signals were received.
