The present disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of 5G communications technologies and IoT-related technologies. The purpose of the present invention is to solve the problem of discharged electrical power in a band caused by a D2D signal transmission adding noise to cellular signal transmission. The present invention may comprise: transmitting downlink data to a terminal from a base station; receiving positive reception acknowledgement (ACK) or negative reception acknowledgement (NACK) information on a physical uplink control channel (PUCCH) according to the results of receiving the downlink data; determining whether an uplink resource where the ACK or NACK information is received is included in a first resource or a second resource; and interpreting, in particular by the base station, the ACK or NACK information as ACK if the uplink resource where the ACK or NACK information is received is included in the first resource.

A stable modulation-index Bluetooth (BT) transmitter circuit includes a baseband modulator circuit to generate a baseband BT signal. An intermediate frequency (IF) circuit adds a frequency offset to the baseband BT signal with a low IF and generates a modulated signal. A digital-to-analog converter (DAC) converts the modulated signal to an analog signal that is upconverted using a voltage controlled oscillator (VCO). The baseband frequency offset is subtracted from the corresponding radio-frequency (RF) signal by reducing the local oscillator (LO) frequency by the same amount. This has the effect of modulating the carrier leakage away from the center frequency of the transmitted BT signal. The resulting RF signal is transmitted to a receiver.

Aspects of the subject disclosure may include, for example, determining that a number of interferers in a portion of a number of spectral segments exceeds a number of filters of a number of filters. Use of the number of filters to filter interference is prioritized responsive to the number of interferers exceeding the number of filters. Interference is filtered in the portion of the number of spectral segments for suppressing at least a portion of the detected interference.
