Abstract: An operation method of an IAB node in a communication system may comprise: measuring a power difference between a first signal received from a first node and a second signal received from a second node; controlling a transmit power of each of the first node and the second node based on the power difference; generating scheduling information for allowing the first node and the second node to simultaneously transmit signals; transmitting the scheduling information to the first node and the second node; and receiving signals that the first node and the second node simultaneously transmit according to the scheduling information by using the transmit power.

Abstract: An operation method of a first terminal, performed in a communication system, may comprise receiving sidelink resource allocation information from a base station; receiving a first sidelink signal from a second terminal based on the sidelink resource allocation information; calculating a path loss experienced by the first sidelink signal based on the first sidelink signal; transmitting a second sidelink signal including information on the path loss experienced by the first sidelink signal to the second terminal; and receiving, from the second terminal, a third sidelink signal to which a sidelink transmit power determined based on the path loss is allocated.

Abstract: An operation method of a relay node may include: receiving, from a first communication node, first data composed of n bits; receiving, from a second communication node, second data composed of m bits; in response to determining that n is greater than m, generating first T-data of m bits excluding (n-m) bits from the n-bits of the first data and first R-data of (n-m) bits; generating third data by performing a network coding operation on the first T-data and the second data; transmitting the third data to the first communication node; and transmitting the third data and the first R-data to the second communication node.

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 herein relates to a method of transmitting uplink data to increase multiplex capacity. The method includes allocating, by each of a plurality of machine type communication user equipment (MTC UE), position information within a single resource block (RB), which is used when transmitting uplink data, to the single RB, generating information about a demodulation reference signal (DMRS) used when demodulating the data received from the plurality of MTC UE, and transmitting the position information within the RB and the information about the DMRS to each of the plurality of MTC UE.
