    摘要： A method for efficiently transmitting and receiving control information through a Physical Downlink Control Channel (PDCCH) is provided. When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces. Here, the UE monitors a UE-specific search space, among the search spaces. The UE-specific search space is given based on a modulus operation using the variable of Yk for the subframe k and a variable C for the subframe k, wherein Yk is defined by: Yk=(A*Yk−1+B) mod D, the variable C is determined based on the number of CCEs (NCCE) divided by the aggregation level (L), and A, B and D are predetermined constant values predetermined regardless of the aggregation levels (L).

    摘要： Disclosed are a method and apparatus for transmitting a reference signal. In a base station apparatus for transmitting a reference signal in a wireless communication system, a processor generates the same scrambling sequence for resource elements (REs) allocated to each layer for reference signal transmission, and spreads or covers Walsh codes such that scrambling sequences generated for the resource elements can be orthogonal to each other on a time axis, in order to generate a reference signal sequence. Here, the Walsh code spreading or covering by the processor is applied on a frequency axis on the basis of a plurality of resource blocks (RBs) or on the basis of a pair of resource blocks, such that mutually different sequences having mutually different sequence values can be mapped between resource blocks or between pairs of resource blocks. A transmission module transmits the reference signal, to which the thus-generated reference signal sequence is applied, to user equipment via each layer.
