摘要： A base station in a mobile communication system determines the number of slots that are to be used to transmit a synchronization signal in a period of the synchronization signal depending on the number of neighbor cells, allocates a synchronization signal region in which the synchronization signal is to be transmitted to a first slot of the determined number of slots depending on a cell identifier of a serving cell, and allocates a reserved region in which no signal is transmitted to slots other than the first slot among the determined number of slots so as to correspond to a position of the synchronization signal region.

摘要： Disclosed herein relates to a resource allocation method for a machine type communication (MTC) device. The resource allocation method for the MTC device includes allocating a control channel with respect to a user terminal to a first time domain of a sub frame, and mixing at least one of a control channel with respect to the at least one MTC device, a data channel with respect to the user terminal, and a data channel with respect to the MTC device in a second time domain of the sub frame, and allocating the mixed channel to the second time domain of the sub frame. Accordingly, in a wireless communication system, control information and data may be transmitted and received to and from the MTC device while maintaining compatibility with the user terminal.

摘要： A method of and an apparatus therefor searching a cell in a mobile station of a communication system in which a plurality of cells are grouped into a plurality of cell groups, and each cell group includes at least two cells. The method includes detecting a primary synchronization signal and a secondary synchronization signal from a received signal, and identifying a cell based on a combination of the primary synchronization signal and the secondary synchronization signal. The secondary synchronization signal is related to the cell group to which the mobile station belongs and the primary synchronization signal is related to the cell to which the mobile station belongs within the cell group.

摘要： Disclosed are a method for generating a random access signal of a machine type communication (MTC) device using a narrow bandwidth, and an MTC device. The method generates a random access signal by allocating a position in a frequency domain of a random access signal dedicated to the MTC device, that is, a position of a frequency for transmission of a random access preamble, to a center position of a base station system bandwidth, or by shifting a center frequency of the MTC device to a position of a random access frequency allocated for a legacy LTE terminal by a base station.
