    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 REs 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 RBs such that mutually different sequences having mutually different sequence values can be mapped between RBs or between pairs of RBs. 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 transmitting packet in a mobile station is provided. The method includes determining whether a resource reserved for a special purpose is overlapped with a resource for transmitting a packet by the mobile station, on the basis of resource allocation information on the mobile station, and delaying the transmission of the packet if the reserved resource is overlapped with the resource for transmitting the packet. Accordingly, it is possible to increase uplink packet transmission efficiency without increasing downlink overhead, by avoiding or adjusting collision of an uplink packet transmission with a time-frequency resource reserved for another purpose.
