5G Beam Sweeping & SSB Beams

In 5G, SSB is the broadcast channel used by the UE to estimate RSRP and thus, it is used for all access related and mobility related decisions. Some implementations have single SSB while others have multiple SSBs and in case of multiple SSBs, the concept of Beam Sweeping comes into play. This session explains that concept and how it works.

GREAT !! Can't wait for the next video !!

[filthykid]

The end was really important :) questions in my mind are :
- how the angle of this SSB beam sweeping is defined? Is it defined by high lever parameter or 3gpp standard etc?
- difference between SSB beams and pdsch/massive mino beams... In a bit of detail as much as possible...

[mysterious_miracle]

Very good one, thanks for the upload.

[anuragchakra]

Thanks sir understood clearly❤.. please make more ...

[navas]

Thanks for nice explanation..How is Beam sweeping differ from beam forming ? Waiting for next vedio...

[Sarbatriks]

Thank you very much for all your videos . Can you plz make a video on how Single Carriers OFDMs are made in the uplink of both LTE and NR . I understand that CP-OFDM has higher PAPR and hence we have SC-OFDMA in uplink of 4G and DFTs-OFDM in uplink of 5G, which are OFDMs disguised as a single carrier wave and thus eliminates PAPR . But i cannot visualise this . Can you explain this phenomenon and also how IDFT/IFFT and FFT/DFT works in OFDM ?

Thanks..

Can you please do a session on UL Time alignment procedure

[akhileshnigam]

Sir, I am unable to understand that how gNB able to know the location of UE using RSRP without knowing PMI value from UE ...

[indramani]

how UE will initimate gNB about the best suited SSB beam from ssb burst, post beem sweeping ?

[m.karthikeyan]

Any video available for 5G cell search?

[coolmunzir]

Cons of having more SSB Beams per burst apart from increased overlapping and interference
