    摘要： A method for efficiently acquiring precoding information and transmitting an uplink signal using the precoding information in a User Equipment (UE) in a Multiple Input Multiple Output (MIMO) scheme is disclosed. The UE receives from a Base Station (BS) a scheduling grant signal including precoding matrix information to be used for an uplink signal transmission from the UE, precodes an uplink signal using the precoding matrix information included in the received scheduling grant signal, and transmits the precoded uplink signal initially to the BS. When retransmitting the uplink signal, if a scheduling grant signal is not received for the retransmission from the BS, the uplink signal is precoded and retransmitted using precoding matrix information included in a latest scheduling grant signal received for transmission of an uplink signal having a Hybrid Automatic Repeat reQuest (HARQ) process number equal to an HARQ process number of the uplink signal to be retransmitted.

    摘要： A scheme of error decoupling for carrier aggregation techniques to support a communication system is provided. The communication system operates with up to 2 codewords for up to 5 carriers, each codeword of each carrier having one acknowledgement/negative acknowledgement (ACK/NACK) or discontinuous transmission (DTX) to enable Hybrid Automatic Repeat reQuest (HARQ) to operate in each carrier. The scheme involves the steps of: performing separation of bits related to ACK, NACK, DTX for each carrier using up to 2 codewords; determining a maximum number of bits related to ACK, NACK, DTX when decoupling is not performed after a maximum number of carriers are used; and grouping the carriers such that separation between ACK, NACK, DTX of each carrier is optimized as long as the maximum number of bits is not exceeded.

    摘要： According to the present invention, one or more PDCCH-SFs are set from among subframes in a predetermined duration so as to force user equipment (UE) to perform a PDCCH blind decoding (BD). Information indicating said set PDCCH-SF is provided to the UE from a base station (BS). The UE performs the PDCCH BD only in the PDCCH-SF which is set to the UE itself, and not to all subframes, and performs HARQ process(es) according to the PDCCH BD. The present invention exhibits the advantages of reducing the number of BDs which the UE has to perform and of reducing the implementation complexity of the UE.
