    Abstract: A base station apparatus for transmitting a reference signal in a wireless communication system is provided in which a processor generates the same sequence for resource elements (REs) allocated to each layer for reference signal transmission and spreads or covers Walsh codes for a user equipment—specific reference signal sequence such that sequences generated for the resource elements can be orthogonal to each other on a time axis. The Walsh code spreading or covering by the processor is applied on a frequency axis based on a plurality of resource blocks (RBs) or based on 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 generated reference signal sequence is applied to user equipment via each layer.

    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.
