Abstract: Proposed is an apparatus and method for increasing the reach area of a random access preamble and uplink data signals in a wireless communication system. An operation method of a transmitter in a wireless communication system may include a process of generating sequences for generating a physical random preamble channel (PRACH) signal, a process of converting the sequences in a frequency domain, a process of dividing the converted sequences into frequency source blocks (RB), a process of allocating the frequency resource blocks to different spatial layers, and a process of transmitting the PRACH signal on the basis of the frequency resource blocks allocated to the spatial layers.

Abstract: Provided is a method for transmitting, by a transmitter, a first data having periodicity through a channel of an unlicensed band:
The transmitter adjusts at least one of transmission timing of the first data and clear channel assessment (CCA) timing for the channel to occupy the channel. The transmitter determines whether the channel may be occupied by performing a CCA on the channel at the CCA timing. The transmitter transmits the first data through the channel at the transmission timing of the first data, when it is determined that the channel may be occupied.-

Abstract: There is provided a method for transmitting, by a transmitter, a signal through an unlicensed band channel. The transmitter transmits an initial signal through the unlicensed band channel to preoccupy the unlicensed band channel when the unlicensed band channel is in an idle status. The transmitter includes a first partial subframe transmitted after the initial signal in a frame burst depending to transmission timing of the initial signal. Further, the transmitter transmits the frame burst through the unlicensed band channel.
