Question: In a Cellular Network using E-UTRA, when the q-QualMinRSRQ-CE parameter is absent from the CellSelectionInfoCE information element, what value does the User Equipment (UE) apply for Qqualmin by default?
Option 1: A predefined threshold of -80 dBm
Option 2: The minimum RSRQ value of the serving cell
Option 3: A value of 0 (zero) for all RSRQ measurements
Option 4: Negative infinity for Qqualmin
Explanation: According to the specifications, if the q-QualMinRSRQ-CE parameter is not present in the CellSelectionInfoCE, the UE defaults to applying a value of negative infinity for Qqualmin. This ensures that any received signal quality (RSRQ) will be considered better than the default threshold, allowing for cell selection based on other available parameters or criteria when q-QualMinRSRQ-CE is not provided.
