What PRACH Format extends cell range to 100 Km?
(long) Format 1
LNADJGNB defines
4G to 5G BTS level relationship
PRACH planning What parameter limits the cell range below the max range allowed by the PRACH preamble format?
Zero Correlation zone
4G coordinates power and sends the information to 5G. Which message 4G uses to transfer this information?

5GC001086 incompatible with
short PUCCH
Proactive Scheduling reduces
UL Latency
by proactively allocating resources to the UE
5GC001070 Semistatic 3/7 1 frame is 10ms and 20slots. How many SS/PBCH?

LNCEL - what object is configured to support LTE to 5G idle mode cell reselection?
NRFIM
NCC
EIRP antenna activa split into 2 physical antenas eg. Horizontal split
6dB
LTE5411 describes
ANR for EN-DC: Fast Neighbor Relation Addition
5G BTS selects an AMF using either NSSAI or RRC Setup from UE that have parameters
SST and SD or
GUAMI or 5G-S-STMSI
5G SA uses what object to configure Connected Mode Mobility
NRREL
5G SA uses what object to support Intra Freq Idle Mode Mobility
NRIAFIM
Subcarrier spacing (scs / ssbScs) is
FDD FR1 is 15 / 15
TDD FR1 is 30 / 30
TDD FR2 is 120 / 240
PRBs PRACH msg 1 occupies for FDD FR1 SCS 15 and Preamble Format 0
6 per PRACH occasion
DSS Ph1 manages shared resources using what eNB to gNB interface
Xp
5GC001464 Transport separation configures what IP addresses
S1-U X2-U and X2-C
EdenNet benefits
Integrates CM resources and applications
Real-time changes
Optimizes Coverage Mobility and Capacity
IDCM benefits
E2E solution with
Faster schedule
Improved quality
Lower risk
RADAR supports what technologies
GSM UMTS LTE 5G SRAN
MOCN vs. MORAN differences
MOCN has multiple PLMNs per cell and shares all settings (nor lists resources) among the PLMNs
MORAN dedicates a cell to a single PLMN though multiple cells can mean multiple PLMNs
What parameter is in the Code Domain Planning
Root Sequence Index
provides isolation in Code Domain
SS/PBCH ssBurstSetPeriod value impacts
20ms reduces overhead
10ms reduces latency
DFT-S-OFDM waveform is generated by Transform Precoding and
CP-OFDM
NR supports how many PCIs?
1008 PCIs organized into 336 groups of 3 [340]
Where is the 5G Contention Free (CF) preamble

LNRELGNBCELL
What 5G TDD Modes have poor 14km support
TDD Modes 2 (1/4) and 3 (3/7) have fewer Guard Slots
TDD Mode 1 (4/6) has more Guard Slots for better coverage
UE Power Savingmeans placing BWP where
BWP is always positioned at the bottom of the channel bandwidth
Long vs. Short PUCCH benefits
4 dBm Coverage improvement and more RRC Connections PER CELL
PCI planning goals are
To prevent collision and confusion conflicts
