摘要

The present disclosure relates to a communication technique for merging IoT technology with a 5G communication system for supporting higher data transmission rates than 4G systems, and a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. In addition, the present disclosure relates to a method for adding or changing a cell, and a device for performing same.

The baseband processor 6-20 performs a function of conversion between a baseband signal and a bitstream according to a physical layer protocol of a first wireless access technology. For example, when data is transmitted, the baseband processor 6-20 generates complex symbols by encoding and modulating a transmission bitstream. In addition, when data is received, the baseband processor 6-20 reconstructs a reception bitstream by demodulating and decoding a baseband signal provided from the RF processor 6-10. For example, in a case where an OFDM scheme is applied, when data is transmitted, the baseband processor 6-20 generates complex symbols by encoding and modulating a transmission bitstream, maps the complex symbols to subcarriers, and then configures OFDM symbols through IFFT calculation and CP insertion. In addition, when data is received, the baseband processor 6-20 divides a baseband signal provided from the RF processor 6-10, by the units of OFDM symbols, reconstructs signals mapped to subcarriers, through FFT calculation, and then reconstructs a reception bitstream through demodulation and decoding. The baseband processor 6-20 and the RF processor 6-10 transmit and receive a signal as described above. Accordingly, the baseband processor 6-20 and the RF processor 6-10 may be called a transmitter, a receiver, a transceiver, a transceiving unit, a communication unit, or a wireless communication unit.
