Question: What is implied if a UE's ue-PowerClass-N-r13 or ue-PowerClass-5-r13 field is absent for a specific E-UTRA band in its radio access capabilities definition?
Option 1: The UE does not support any power class for that band.
Option 2: The UE supports the default UE Power Class for that band, as specified in E-UTRA transmission and reception standards.
Option 3: The UE automatically adjusts to the highest supported power class for the band.
Option 4: The UE is incapable of transmitting on that specific E-UTRA band.
Explanation: According to E-UTRA standards, the absence of ue-PowerClass-N-r13 or ue-PowerClass-5-r13 fields for a particular band implies that the User Equipment (UE) supports the default power class configuration for that band, as outlined in relevant technical specifications for E-UTRA transmission and reception.
