ave bands, it may be necessary to exploit high antenna gains even during initial access and in general for improving the control channel coverage. However, directionality can significantly delay the access procedures and make the performance more sensitive to the beam alignment. The Rel-15 NR is designed to support analog beamforming in addition to digital precoding/ beamforming. In high frequencies, analog beamforming may be beneficial from an imple- mentation viewpoint despite the fact that analog beamforming may constrain the transmit/ receive beam to be formed in one direction at a given time and further requires beam sweeping, where the same signal is repeated in multiple OFDM symbols but on different transmit beams. Beam sweeping would ensure that the signal can be transmitted with high directionality in order to cover the entire cell area. The NR has specified control/signaling schemes to support beam management procedures including an indication to the device to assist the selection of an appropriate receive beam. For large number of antennas, beams are narrow and beam tracking may fail; therefore, beam-recovery procedures have been defined where a device can trigger the beam-recovery procedure. A cell may have multiple transmission points each with beams and the beam-management procedures to allow UE-transparent mobility for seamless handover between the beams of different transmission points. In addition, uplink-centric and reciprocity-based beam management is also possible by utilizing uplink signals [14]. In some cases, a suitable transmit/receive beam pair for the downlink transmission will also be a suitable beam pair for the uplink transmission direction and vice versa. The NR refers to this as downlink/uplink beam correspondence, where it is sufficient to determine a suitable beam pair in one direction and use the same beam pair in the opposite direction. Since beam management is not intended to track fast-varying and frequency-selective channels, beam correspondence does not require that downlink
