Abstract: A method of transmitting an acknowledgement (ACK) signal in a wireless communication system is provided. The method includes: establishing a first wireless connection between a first and second electronic devices; establishing a second wireless connection between the first electronic device and a source device; transmitting, by the first electronic device, communication parameter information to the second electronic device; transmitting, by the first electronic device, a data request to the source device; receiving, by the first electronic device, a data packet from the source device in response to the data request; receiving, by the second electronic device, the data packet from the source device based on the communication parameter information; transmitting, by the first electronic device, a first ACK signal to the second electronic device; and transmitting, by the second electronic device, a second ACK signal to the source device based on the first ACK signal.

Abstract: According to the disclosure, a method performed by a radio unit (RU) may comprise: receiving configuration information for a remote interference management (RIM)-reference signal (RS) from a distributed unit (DU); receiving a message containing bit data for the RIM-RS from the DU; generating a complex-valued symbol corresponding to the bit data for the RIM-RS; generating a RIM-RS signal by performing at least one of phase rotation or phase difference compensation for the complex-valued symbol on the basis of the configuration information; and generating a baseband signal corresponding to the RIM-RS signal based on an inverse fast fourier transform (IFFT) and cyclic prefix (CP) insertion of the RU.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A method for transmitting and receiving data comprises the steps of: receiving a first synchronization block over a first narrow band; identifying whether an indicator indicating that the first narrow band is not allocated to a terminal is included in the first synchronization block; and performing synchronization in the first narrow band if the indicator indicating that the first narrow band is not allocated to the terminal is not included in the first synchronization block.
