摘要

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A control method of a user equipment (UE) in a wireless communication system is provided. The method includes receiving packet data convergence protocol (PDCP) configuration information including information indicative of whether a PDCP layer supports out-of-sequence delivery; identifying whether the PDCP layer supports out-of-sequence delivery based on the PDCP configuration information; and processing a PDCP protocol data unit (PDU) based on a result of identifying whether the PDCP layer supports out-of-sequence delivery.

The RF processor 1j-10 may perform a function for transmitting/receiving a signal through a radio channel, such as band conversion and amplification of a signal. The RF processor 1j-10 may up-convert a baseband signal received from the baseband processor 1j-20 into an RF band signal, transmit the RF band signal through an antenna, and down-convert an RF band signal received through the antenna into a baseband signal. The RF processor 1j-10 may include a transmission filter, a reception filter, an amplifier, a mixer, an oscillator, a DAC, and an ADC. In FIG. 1J, only one antenna is shown, but the eNB may include multiple antennas. The RF processor 1j-10 may include multiple RF chains. The RF processor 1j-10 may perform beamforming.

For the beamforming, the RF processor 1j-10 may adjust the phase and size of each of signals transmitted/received multiple antennas or antenna elements. The RF processor may perform a downlink MIMO operation by transmitting one or more layers.
