5G NR BFR – Beam Failure Recovery
The 5G communication specially at higher frequencies or mmWave is using Massive MIMO with Beamforming. Beamforming is a signal processing technique that allows gNB send targeted beams of data to […]
5G NR SS-RSRP Value Measurement Mapping
UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management procedures. RSRP measurement generated and reported at both Layer 1 […]
5G mmWave 28 GHz Band Link Budget – n257
The combination of 5G NR technology and millimeter wave bands pioneer a new level of mobile performance with ultra-high speeds and low latencies. Momentum behind 28 GHz is growing, with […]
5G NR Antenna Port – Logical and Physical Antenna Mapping
Downlink multi-antenna transmission is a key technology of 5G NR. Signals transmitted from different antennas ports will experience different “radio channels” even if the set of antennas are located at […]
Smart Antennas and Beam-forming, Understanding with GNU : Part 3
Recap from part-2 of this article Smart antenna systems or sometimes known as adaptive antenna array systems are composed of two major blocks; An adaptive antenna array block and a […]
Smart Antennas and Beamforming, Understanding with GNU : Part 1
Introduction and Definitions: LTE transmission mode 7,8 and 9 defines fixed precoder based beamforming and adaptive precoder based beamforming. Main advantage of beamforming and smart antenna system is that by […]
