    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.

    摘要： Multiple Transport Blocks (TBs) or data streams are provided in Multi-Input-Multi-Output (MIMO) wireless communication systems herein. The base station (eNB) controls and schedules all downlink and uplink transmission to and from User Equipments, which need to receive an uplink grant from BS/eNB before they transmit. The uplink grant is carried as one of the control indication message in the downlink. The BS/eNB also transmits ACK/NACK information in the HARQ indication channel to the UE for each of the transport blocks. The UE detects the control indication to determine the actual uplink scheduling, as well as the HARQ indication. A method of transmitting a control indication message, which contains a detailed transmit format for one of the TBs to be transmitted, while allowing simultaneous communications on the other TBs is also enclosed.
