5G NR-Master Information Block (NR-MIB) Over all structure of MIB and SIB in NR is almost similar to LTE and other legacy technologies. However there is a major difference related to the periodical transmission of SIBs. In LTE and other legacy technologies the SIBs are broadcasted priodically regardless of whether UE wants it or not. … Read more
NR-Secondary Synchronization Signal (SSS) NR-Secondary Synchronization Signal: 5G-NR Secondary Synchronization Signal (SSS) is Physical Layer specific signal and help UE to get subframe boundary. It is similar to PSS, as it is also an m-Sequence. NR-SSS has following characteristics NR-SSS a m-Sequence made up of 127 Values SSS is mapped to 127 active sub carriers around … Read more
NR-Primary Synchronization Signal (PSS) 5G-NR Primary Synchronization Signal (PSS) is Physical Layer specific signal and help UE to get Radio Frame Boundary. It is type of an m-Sequence which is a special type of LFSR (Linear Feedback Shift Register) sequence provides the longest non-repeating sequence. NR-PSS has following characteristics NR-PSS a m-Sequence made up of … Read more
5G-NR Cell:Physical Cell ID Like LTE, 5G NR also has synchronization signal and known as Primary Synchronization signal (PSS) and Secondary Synchronization signal (SSS). These signals are specific to NR physical layer and provides following information required by UE for downlink synchronization. PSS provides Radio Frame Boundary ( Position of 1st Symbol in a Radio frame) SSS … Read more
5G NR Reference Signals (DMRS, PTRS,SRS and CSI-RS) To increase protocol efficiency, and to keep transmissions contained within a slot or beam without having to depend on other slots and beams, NR introduces the following four main reference signals. Demodulation Reference Signal (DMRS) Phase Tracking Reference Signal (PTRS) Sounding Reference Signal (SRS) Channel State Information … Read more

5G/NR Channel Codes Evolution Consideration and 3GPP Recommendation on Polar Codes. In order to meet higher data rates and more diverse requirements of typical NR scenarios including eMBB, mMTC, and URLLC, a powerful and flexible channel coding scheme is one of the fundamental components of the NR access technology. In the recent RAN1# discussion, various … Read more
5G Network Abbreviations and Terminologies Below is the list of a few 5G Network Abbreviations and Terminologies used in 5G NR. Our team is continuously updating it. Please do visit regularly to get in touch with new terminology and abbreviations related to 5G. New RAN: A Radio Access Network which can support either NR/E-UTRA or … Read more
5G Specification and Structure of the 3GPP. 3GPP starts its work on 5G with its first meetings in the US next month. The work item approved by RAN plenary (RP-170847) primarily targets eMBB and URLLC scenario and services requirements. Frequency ranges up to 52.6 GHz are considered for the 5G, while OTA RF requirements will … Read more
5G NR Deployment & Spectrum Scenarios is expected to be into different morphology namely Indoor hotspot, Dense Urban, Rural, Urban Macro, High-speed train, mMTC, and Urban grid with connected car. These all deployments is expected to in specific spectrum band or range of frequency to accommodate the High date rate, deep indoor coverage; mobility support … Read more
