Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.

Abstract: Provided is a method for feeding back a channel quality indicator (CQI) by a terminal. The terminal receives, from a base station, at least one reference signal through at least one of multiple beams of the base station. The terminal measures a signal-to-interference plus noise ratio (SINR) for the at least one reference signal. The terminal determines a first level corresponding to the measured SINR among levels of a first CQI. In addition, the terminal feeds back the first CQI having the first level to the base station.
