    摘要: A control information transmission and reception method based on a spatial-multiplexing gain, are provided. The control information may be transmitted by obtaining the spatial-multiplexing gain using an E-PDCCH region, and thus, a transmission efficiency of the control information may be improved. The common control information used for decoding the E-PDCCH may be transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information. Information associated with an indicator indicating whether the E-PDCCH is to be used during a subsequent resource allocation period may be transmitted, and thus, whether decoding with respect to the E-PDCCH is to be performed during the subsequent allocation period may be determined

    摘要: A method and apparatus for allocating resource between uplink ACK/NACK channel and downlink control channel supporting spatial multiplexing in an OFDM-based wireless communication system which configures uplink ACK/NAK channel implicitly using reference signals for discriminating among resource allocation spaces and physical channel resource. The method is capable of multiplexing the uplink ACK/NACK channel associated with the control channel extended by spatial multiplexing into the uplink ACK/NACK channel resource which does not support spatial multiplexing.

    摘要: A transmission scheme newly adds a Demodulation Reference Signal (DM-RS) to estimate a channel response for demodulation. When a transmission scheme based on Long Term Evolution Common Reference Signal (LTE CRS) is set in a user, a corresponding user cannot receive data in a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) sub-frame. To solve this problem, the present scheme separates and sets a transmission mode for sub-frame and a transmission mode for MBSFN.

    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 method and apparatus for transmitting/receiving reference signals in Long Term Evolution (LTE) and LTE-Advanced (LTE-A) systems includes determining whether a dedicated reference signal is detected in a current subframe; estimating, if a dedicated reference signal is detected in the current subframe, a data channel using the dedicated reference signal to receive data; and estimating, if no dedicated reference signal is detected in the current subframe, a data channel using a common reference signal detected in the current subframe to receive data. The transmission scheme uses a DeModulation Reference Signal (DM-RS) for channel response estimation. To secure backward compatibility of the LTE-A system, a Common Reference Signal is transmitted in normal subframes.
