1. A method of determining a downlink transmit power from a base station at a wireless terminal, the base station and the wireless terminal having a plurality of orthogonal frequency division multiplexing (OFDM) symbols for transmission, the method comprising:

  • receiving a signaling parameter from the base station; and

    determining a ratio of a first ratio of traffic data to pilot, T2P, for first OFDM symbols to a second ratio of T2P for second OFDM symbols based on the signaling parameter and a number of cell-specific antenna ports configured in the base station,wherein the ratio of the first ratio to the second ratio for one cell-specific antenna port for the signal parameter 0, 1, 2, or 3 is respectively 1, 4/5, 3/5 or 2/5.
