    Abstract: A method of mapping symbols of a physical control format indicator channel (PCFICH) is described. A start position of a resource element to map the symbols for the PCFICH is determined by flooring a value, obtained by multiplying the number of resource blocks by a variable proportional to a symbol index for the PCFICH and then dividing the multiplied result by 2, wherein the resource blocks are transmitted in downlink. The symbols are mapped in the start position. Therefore, a problem of wasting resource elements or not being able to implement mapping can be solved by applying a simple mapping rule while mapping symbols of the PCFICH.

    Abstract: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.

    Abstract: A method of controlling an uplink transmission in a wireless communications system, and a user equipment therefore are discussed. The method according to one embodiment includes configuring the user equipment with multiple component carriers; receiving first configuration information for allocating one or more component carrier sets; receiving second configuration information for periodically transmitting an uplink signal; receiving control information for configuring states of component carriers, by which a downlink component carrier and an uplink component carrier are controlled to be in a same state; and performing a procedure for periodically transmitting the uplink signal on an uplink component carrier in use of the first configuration information, the second configuration information and the control information. When the uplink component carrier is in the active state, a transmission of the uplink signal is performed. When the uplink component carrier is in the non-active state, the transmission of the uplink signal is skipped.

    Abstract: A method for transmitting acknowledgement/negative acknowledgement (ACK/NACK) signals by an apparatus in a wireless communication system is discussed. The method includes spreading ACK/NACKs using spreading codes of a spreading factor, the spreading factor being one of a spreading factor 2 and a spreading factor 4; and transmitting each of the one or more physical hybrid ARQ indicator channel (PHICH) groups through a plurality of units of four resource elements, each PHICH group carrying one or more spread ACK/NACKs, wherein the number of PHICH groups for she spreading factor 2 is determined as twice of the number of PHICH groups for the spreading factor 4.
