Abstract: The provided is a method for transmtting HARQ-ACK in a LTE system, which is applicable to a situation that an upink subframe is occupied in an FDD or TDD sytem. The method is implemented as follows. A UE receives information from an eNB, and determines the assignment of uplink subframes in a cell. The UE determines the transmission of HARQ-ACK according to the assignment of uplink subframes in the cell. By the provided method, the transmission of HARQ-ACK of PDSCH is less influenced when an uplink subframe in the FDD or TDD system is occupied.

Abstract: An apparatus and a method for feeding back data receiving status, applied to a system, are provided. The method includes sequencing, by a User Equipment (UE), downlink subframes for transmitting data with respect to each Component Carrier (CC), generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing, where X≦M, wherein M is the number of downlink subframes on each CC, and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly, the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission, saves the uplink overheads occupied by the receiving status feedback information, and increases the uplink coverage area.

Abstract: A base station includes a reference signal allocator that allocates a first layer of dedicated reference signals and a second layer of reference signals to the same resource elements in a first resource block. The reference signals are allocated to two adjacent resource elements corresponding to a first OFDM symbol and a second OFDM symbol on a first, second, and third subcarriers of the first resource block. The base station also includes a reference signal multiplexer that multiplexes the first layer with the second layer. A first cover code W1 is applied to the first layer. A second cover code W2, different from the first cover code, is applied to the second layer in a first and third subcarriers, and a variation of the second cover code W2′ is applied to the second layer in a second subcarrier.
