    摘要: A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.

    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: A resource allocation method of a base station in a wireless communication system based on a radio frame including a plurality of subframes including at least one first-type subframe and at least one second-type subframe is provided. The method includes generating first-type downlink control information including resource allocation information on the first-type subframe, generating second-type downlink control information including resource allocation information on the second-type subframe, and transmitting the first-type subframe including the first-type downlink control information and the second-type downlink control information, wherein the second-type subframe is transmitted with a lower transmit power than the transmit power of the first-type subframe.
