🔹New Frequency Bands in 5G R18 🔹3GPP introduced 7 new frequency bands in 5G Release 18. 🔹In FR1: 🔹1 TDD bands. 🔹6 FDD bands. 🔹FR1 FDD band n254 (2.5 GHz) was introduced for 5G Non Terrestrial Networks (NTN). #5G

3GPP Release 17 and 18: 5G NR Beam Sweeping, High Band (FR2-2) using SSB Pattern F (64 SSBs) ✅ Here I try to depict how using SSB pattern F in High band (FR2-2), a 5G base station can send 64 SSBs within a burst . #5G #5GNR #4G ✅For more information about Beam Sweeping, Please refer to my last post in YouTube which is about "5G Initial Access Process and SSB Beam Sweeping". Here is the link of video: https://lnkd.in/eyTVGiMT

Well elaborated materials by Rahim Navaei. However #NR #SSB_Beam_Sweeping is not necessarily a good solution/architecture despite it is standardised. There are some draw back of using SSB beam sweeping and using SSB narrow beam compared to well performing wide beam developed and used by #Ericsson. Listed a few bullet points below as a disadvantage of SSB beam sweeping: - May degrade initial access latency - Affect UE battery consumption - Higher overhead, can lead to reduce peak rate SSB beam sweeping will address downlink coverage limitation while in link budget normally limitation is in uplink. Needless to mention that the higher SSB #SINR gained by SSB beam sweeping can be achieved by other functions

🔹New Frequency Bands in 5G R17 🔹3GPP introduced 14 new frequency bands in Release 17. 🔹In FR1: 🔹3 TDD bands. 🔹6 FDD bands. 🔹1 SDL band. 🔹3 SUL bands. 🔹In FR2: 🔹1 TDD band. 🔹FR1 FDD bands n255 and n256 was introduced for 5G Non Terrestrial Networks (NTN). #5G

Final regulations published for a forthcoming mmWave spectrum auction. Ofcom, the UK communications regulator, has published final regulations for a #mmWave #spectrum #auction in the 26 GHz and 40 GHz bands. The approach balances competitive allocation in high density areas with first come, first served in low density areas. #5G #mobile https://lnkd.in/eMprDS7u

Mobile operators may face a spectrum deficit of up to 963 MHz, but adopting highly efficient technologies including #RFfilters, mMIMO, and unlicensed spectrum will help. https://bit.ly/3rEqcB2 #5G

#5G_Notes #Nokia_NSA_Notes There is a new concept in NSA Mode called UL Leg switching between 4G & 5G.. What is it? & How its working? - UE in NSA Mode can send in UL path over NR or 4G based on Radio Conditions. - So based on SINR value for UE will send in UL over LTE or NR path. Benefits: -NR cell edge performance is improved -NR UL coverage extension -NR DL service continuation
