Question: Upon receiving SystemInformationBlockType2, what action does a UE (User Equipment) take if it is in RRC_CONNECTED mode and has received `rlf-TimersAndConstants`, but the timer T311 is not running, and the UE supports multi-band cells?
Option 1: Update all values of timers and constants in `ue-TimersAndConstants`.
Option 2: Disregard `additionalSpectrumEmission` and `ul-CarrierFreq` only if received for a different PLMN.
Option 3: Forward `rlf-TimersAndConstants` to upper layers for further processing.
Option 4: Disregard `additionalSpectrumEmission` and `ul-CarrierFreq`, if received, while in RRC_CONNECTED.
Explanation: According to the specifications, if a UE is in RRC_CONNECTED mode, T311 is not running, and the UE supports multi-band cells, it shall disregard `additionalSpectrumEmission` and `ul-CarrierFreq`, if received, while in RRC_CONNECTED. This action ensures the UE correctly configures itself based on its capabilities and the current connection state.
