In cell selection, RSRP is used as the default quantity measurement.
-
True
-
False
Correct Answer
A. FalseExplanation
In cell selection, RSRP is not used as the default quantity measurement. RSRP stands for Reference Signal Received Power and it is a measurement used to determine the signal strength in a cellular network. However, in cell selection, the default quantity measurement used is RSRQ (Reference Signal Received Quality), which takes into account both the signal strength and interference levels. Therefore, the statement is false.Rate this question:

When an UE tried to camp on a cell, UE also measures cells from other PLMN rather than PLMN in its sim card.
-
True
-
False
Correct Answer
A. TrueExplanation
When a user equipment (UE) attempts to connect to a cell, it also performs measurements on cells belonging to other public land mobile networks (PLMN) in addition to the PLMN associated with its SIM card. This is done to gather information about neighboring cells and their signal strengths, which can help the UE make an informed decision about which cell to camp on. Therefore, the statement is true.Rate this question:

In cell selection, PMaximum allowed power in Pcompensation is set based on the current highest UE power in the network.
-
True
-
False
Correct Answer
A. FalseExplanation
In cell selection, the maximum allowed power in Pcompensation is not set based on the current highest UE power in the network. The maximum allowed power in Pcompensation is typically determined by various factors such as network capacity, interference levels, and power control algorithms.Rate this question:

In cell reselection, UE measures neighbor cells based on neighbor cell information sending in SIB4, SIB5, SIB6 and SIB7.
-
True
-
False
Correct Answer
A. FalseExplanation
In cell reselection, UE measures neighbor cells based on neighbor cell information sending in SIB4, SIB5, SIB6, and SIB7. This statement is false because in cell reselection, UE measures neighbor cells based on neighbor cell information sent in SIB3, not SIB4, SIB5, SIB6, and SIB7.Rate this question:

In intra-freq cell reselection, there are 2 main steps, i.e. measurement trigger criteria and cell reselection criteria. The measurement quantity to be used should be the same.
-
True
-
False
Correct Answer
A. FalseExplanation
The explanation for the given correct answer, which is False, is that in intra-freq cell reselection, the measurement quantity to be used does not necessarily have to be the same. The measurement trigger criteria and cell reselection criteria can be based on different measurement quantities.Rate this question:

When deploying LTE, operator usually preferred to let UE to stay more in LTE. In cell reselection in order to lead UE to stay more in LTE, which of the following is incorrect?
-
In Low priority cell reselection, increase ThrshServLow
-
In Low priority cell reselection, decrease ThreshXLow
-
In High priority cell reselection, decrease ThreshXHigh
-
In cell reselection measurement trigger criteria, increase SnonIntraSearch
Correct Answer
A. In High priority cell reselection, decrease ThreshXHighExplanation
In order to lead UE to stay more in LTE during cell reselection, operators usually increase the threshold values for low priority cell reselection. This means that the UE will be less likely to reselect to a lower priority cell. Therefore, the statement "In High priority cell reselection, decrease ThreshXHigh" is incorrect because decreasing the threshold for high priority cell reselection would make the UE more likely to reselect to a higher priority cell, which is contrary to the operator's preference.Rate this question:

If a cell is barred, none of UE access class can use or enter to the cell anymore
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because if a cell is barred, it means that certain UE access classes are restricted from using or entering the cell. However, there may still be other UE access classes that are allowed to access the cell. So, the statement that none of the UE access classes can use or enter the cell anymore is incorrect.Rate this question:

If there are a lot of users in a cell, in order to increase paging capacity Nb should be set to a higher value.
-
True
-
False
Correct Answer
A. TrueExplanation
In a cellular network, paging is the process of locating a mobile device when there is an incoming call or message. The parameter Nb represents the maximum number of users that can be paged simultaneously in a cell. If there are a lot of users in a cell, setting Nb to a higher value increases the paging capacity. This means that more users can be paged simultaneously, reducing the chances of paging failures and improving the overall efficiency of the network. Therefore, the statement is true.Rate this question:

UE battery will be consumed more when Nb is set to a high value.
-
True
-
False
Correct Answer
A. FalseExplanation
When Nb is set to a high value, it means that the number of users in the system is high. In this case, the UE (User Equipment) battery will not be consumed more. Instead, the battery consumption will be higher when Nb is set to a low value, indicating a lower number of users in the system. Therefore, the given answer "False" is correct.Rate this question:
