1. A method for operating a base station comprising:
- transmitting physical reference signals precoded at a physical layer, andtransmitting via a physical channel semi-static decoding information for use in physical layer decoding of said physical reference signals;
wherein said decoding information is incorporated into one or more data units at a layer higher than the physical layer;
wherein one or more physical reference signals are transmitted in a single sub-frame for use in physical layer decoding of a physical channel in a plurality of sub-frames, andwherein the decoding information uses a bitmap to indicate an identity of a sub-frame in which said one or more physical reference signals can be found.
