    摘要: A method is provided for determining reference signal positions in a frequency-time domain in an Orthogonal Frequency Division Multiple Access (OFDMA) system. A plurality of sub-carriers are selected in one resource block according to a predetermined mother pattern for reference signal allocation. When a single resource block is assigned for transmission to a user, the reference signal positions are determined corresponding to the plurality of selected sub-carriers in the single resource block. When multiple resource blocks are assigned for transmission to a user, the reference signal positions are determined in the multiple resource blocks by reducing a number of the plurality of selected sub-carriers in the mother pattern for at least one of the multiple resource blocks.

    摘要: The present invention is directed to a coating composition comprising (i) a corrosion inhibitor and the (ii) reaction product of a calcium compound with an acid compound. The coating composition is deposited onto a substrate prior to the application of a pre-treatment coating composition (conversion coating) onto the substrate. The present invention is also directed to a substrate that comprises a coating system that comprises such a coating composition.
