Abstract

Transmitting physical signals precoded at the physical layer, and transmitting via a physical channel precoded at the physical layer decoding information for use in physical layer decoding of said physical signals; wherein said decoding information is incorporated into one or more data units at a layer higher than the physical layer. Transmitting in a single sub-frame one or more physical reference signals for use in physical layer decoding of a physical channel in a plurality of sub-frames.
