Question: How does a User Equipment (UE) handle a received value in Radio Resource Control (RRC) protocol that is set to an extended value not defined in its supported transfer syntax version?
Option 1: The UE ignores the entire message and waits for a retransmission.
Option 2: The UE applies default behavior as specified in the RRC protocol for undefined values.
Option 3: The UE sends an error indication to the base station (eNB/gNB) and continues with the existing configuration.
Option 4: The UE considers the value as not comprehended and follows generic error handling procedures unless procedure-specific handling is defined.
Explanation: According to the principles of generic error handling in RRC protocol, if a UE encounters an extended value that is not defined in its supported transfer syntax version, it should treat this value as not comprehended. In such cases, the UE would typically follow the defined generic error handling procedures, unless there are specific instructions provided within the context of a particular procedure that override these general rules.
