What is an SS block?
SS Block(SSB) stands for Synchronization Signal Block and in reality it refers to Synchronization/PBCH block because Synchnronization signal and PBCH channel are packed as a single block that always moves together.
What is SSB 5G NR?
Cell search is the procedure for a UE to acquire time and frequency synchronization with a cell and to detect Physical layer Cell ID (PCI) of the cell.
What defines the NR cell?
What is 5G New Radio? 5G is the fifth generation of wireless technology and NR stands for a new radio interface and radio access technology for cellular networks—a physical connection method for radio based communication. Other kinds of radio access technologies include Bluetooth, Wi-Fi and 4G LTE.
How do I check my SSB frequency?
SSB Frequency Position = DL- ARFCN – (6*SCS)/ΔFGlobal, ΔFGlobal = 15kHz. If the RB number is even the SSB Frequency Position is equivalent to dl-ARFCN. If the number is odd the SSB Frequency Position is lower than the DL-ARFCN: SSB Frequency Position = DL- ARFCN – (6*SCS)/ΔFGlobal, ΔFGlobal=15kHz.
What is PSS and SSS in LTE?
In LTE, there are two downlink synchronization signals which are used by the UE to obtain the cell identity and frame timing. Primary synchronization signal (PSS) Secondary synchronization signal (SSS)
What is TRS in 5G?
In 3GPP TSG RAN1 Meeting# 86bis, agreement is achieved that the reference signal for phase tracking is supported for both 5G downlink and uplink. The preliminary design of tracking reference signal (TRS) for orthogonal frequency division multiplexing (OFDM) waveform has been done.
What is PRB in 5G?
Physical Resource Blocks (PRBs) PRBs are the resource blocks which are used for actual transmission/reception. A set of PRBs belongs to and form a BWP. PRBs for a specific subcarrier configuration defined within a BWP are numbered from 0 to (size of BWP – 1). Each BWP has its own set of PRBs.
What does NR mean in LTE?
5G New Radio, or 5G NR, is a set of standards that replace the LTE network 4G wireless communications standard. An important goal of 5G NR is to support the growth of wireless communication by enhancing electromagnetic radiation spectrum efficiency for mobile broadband.
What is Voice over NR?
Voice over NR (VoNR) indicates a scenario where the NR network does support voice services and the 5GC offers a connection to IMS. The primary deployment focus of VoNR is standalone operation (SA) where 5GC connects to IMS supporting voice services.
What is SSB frequency?
A marine SSB system operates on marine radio spectrums called shortwave, medium frequency and high frequency — 2 MHz-26 MHz. This radio spectrum is shared with hundreds of other radio users including shortwave broadcasts, Ham radio, FEMA, the American Red Cross, and long-range aircraft.
What is absolute frequency SSB?
absoluteFrequencySSB: It represent the center frequency of SSB Block. A SSB block is 20 RBs results 20 * 12 =240 Subcarriers and from above logs snippet absoluteFrequencySSB= 643008 (NREF)
Why SSS is placed before PSS?
SSS helps to achieve radio frame synchronization and deduce a pointer towards 1 of 168 Physical layer Cell Identity (PCI) groups. Below diagram shows how PSS and SSS helps finding the Physical Layer Cell ID.
