Test: Guillermo

Question 1

What carries DL/UL signaling information?

Answer 1

SIB1 [153]

Question 2

What PRACH Format extends cell range to 100 Km?

Answer 2

(long) Format 1 [363]

Question 3

Long vs. Short PUCCH benefits

Answer 3

4 dBm Coverage improvement and more RRC Connections PER CELL [525]

Question 4

Special Events increase capacity by

Answer 4

Disabling Carrier Aggregation. [575, 587]
CA enabled = 106 connections
CA disabled = 320 connections
PUCCH is limited by CA reporting Harq, Ack and CSI for each carrier.

More connections but less throughput.

Question 5

What tool includes type0CoresetConfigurationIndex?

Answer 5

Throughput and Capacity Planning tool [90]
Adaptive PDCCH Configuration Tool [90]

Question 6

NRDIM calculates

Answer 6

Expected Throughput [442]
* slot format
* number of beams
* sspbch period
* prach configuration index

Question 7

DSS Ph3 allows 5G to use up to how many resources

Answer 7

100% DL and 70% UL resources [1001]

Question 8

Nokia proprietary logical DSS Phase 1 Xp interface handles what?

Answer 8

Mgmt of resources’ split between LTE+NR carriers shared during DSS Phase 1 [997]
[998]
* LTE+NR schedulers discuss load information
* Single Shared carrier between LTE + NR [998]
* Same center frequency, bw and time for both

Question 9

DSS Phase 1 splits resources how?

Answer 9

DL uses TDD resources
UL uses FDD resources

Question 10

When planning RF what do you choose: microwave, transmission capacity or throughput KPIs?

Answer 10

KPIs for Throughput / Performance

Question 11

5G NR PCIs

Answer 11

1008 PCIs organized into 336 groups of 3 [340]

Question 12

NRBTS SA supports how many slices?

Answer 12

20 SNSSAIs [958]

Question 13

nrCellIdentity concatenates what fields

Answer 13

nrBtsId and lcrid [740]
gnbIdlength (22 to 32 bits) means lcrid is (36-gnbIdLength) bits
nrCellIdentity = nrBtsId x 2^(36-gnbIdLength) + lcrid

Question 14

What triggers Event A2?

Answer 14

Serving cell becomes poor (worse than threshold) [897]

Question 15

What does NRBTS.NRSYSINFO_PROFILE.NRIAFIM supports?

Answer 15

Cell reselection towards NR Intra-Frequency

Question 16

What does the Initial BWP include?

Answer 16

Coreset 0 and SS/PBCH are completely within Initial BWP [766]

‘Adaptive PDCCH Configuration Tool’ recommends

locationAndBandwidthDl: crbSizeDl = crbStartDl = coreset0

locationAndBandwidthUl: crbSizeDl = crbStartDl = sameAsDl

Question 17

5G to 4G Neighbor planning uses MOs

Answer 17

LTEENB (NSA)
NRADJECELL + NRRELE (HOs)
NRRELLTE (DSS, not recommended to configure)
[681]

Question 18

EdenNet helps with

Answer 18

Neighbor planning [33], e.g., rootSequenceIndex [605]

Example
zeroCorrelationZone = 10 means 64 preambles that can allocate these 13 indices: 168, 200, 232, 268, 324, 358, 390, 422, 454, 486, 518, 550, 600, 651

Note the indices are spaced unevenly

Question 19

MIND can be used for

Answer 19

Consistency checking
* type0CoresetConfigurationIndex [91]
* beam angles [183]
* prachConfigurationIndex [387]
* Admission Control Thresholds [562]
* Max Num PxschAllocationPerSlot (UE scheduled) [676]
* pagingTargetRate [774]
* VoNR drbinactivitytimersa5qi1 [923]
* permitted chBw [972]

Question 20

LTEPAT/EMIL/MUSA used for

Answer 20

Neighbor planning [33]
* Processing TTI logs to Indicate beam usage [279]
* DL TTI Traces include beam type information [282]
* Confirming DL SRS BF is working [284]

Quantify DL SRS Beam utilization [1019]

Question 21

MOCN vs. MORAN differences

Answer 21

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

Question 22

RADAR supports what technologies

Answer 22

GSM UMTS LTE 5G SRAN

Question 23

IDCM benefits

Answer 23

E2E solution with
Faster schedule
Improved quality
Lower risk

Question 24
