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.

說明書

The RF processor 20-10 may perform a function, such as signal band change, amplification, etc., for transmitting or receiving a signal through a wireless channel. That is, the RF processor 20-10 upconverts a baseband signal provided from the baseband processor 20-20, into an RF band signal, and then transmits the RF band signal through an antenna, and downconverts an RF band signal received through the antenna, into a baseband signal. For example, the RF processor 20-10 may include a transmission filter, a reception filter, an amplifier, a mixer, an oscillator, a digital-to-analog converter (DAC), an analog-to-digital converter (ADC), and the like. In FIG. 20, only one antenna is illustrated, but the RF processor 20-10 may include a plurality of antennas. Furthermore, the RF processor 20-10 may include a plurality of RF chains. Moreover, the RF processor 20-10 may perform beamforming. To perform beamforming, the RF processor 20-10 may adjust the phase and size of each of signals transmitted or received through a plurality of antennas or antenna elements. The RF processor 20-10 may perform a downlink MIMO operation by transmitting at least one layer.
