Introduction In a wireless communication system, transmitted signals experience distortion and attenuation as they propagate through the environment. This effect is usually modelled as a linear time-invariant system...
In 5G, during initial network access, a UE does a completes a band scan for SSB decodes the PBCH. The...
The RSRQ (Referece Signal RecivedQuality) is a measurement performed by the UE to know the Quality of recieved Reference Signals....
5G PDCCH Channel Overview The physical downlink control channel (PDCCH) in NR carries Downlink Control Information (DCI). In this post...
UE does measurement of SS-RSRP and use it for cell selection, cell reselection, power control, mobility procedures and beam management...
Released 3GPP standards on MIMO are shown in below image. As you know, Coordinated Multipoint (CoMP) is a type of Cooperative...
A 5G UE picks a random preamble for RACH procedure to get the uplink synchronisation. The preamble is referenced with...
In 5G NR, RSRP measurement is performed and reported at Layer 1 (Physical Layer) and Layer 3 (RRC Layer). For...
Multi-path propagation in a radio signal transmission causes time delays, signal distortions, and so on. Let us discuss basic theories...
