Abstract
Deploying cellular networks in millimeter wave (mmWave) frequencies require coping with rapid channel variations and severe free-space pathloss and atmospheric absorption. In order to make use of the large portions of novel spectrum available at mmWave frequencies, highly-directional antennas generating radio beams (beamforming) are used at base station and mobile terminal side. This presentation presents the novel mechanisms introduced with 5G New Radio (NR) air interface for allowing the use of beamforming both for control and data channels, including (a) synchronization and initial access, and (b) beam management procedures.
