Abstract: Systems, methods, apparatuses, and computer program products for security handling in, for example, cells that support multiple frequency band indication are provided. One method includes receiving, for example by a source evolved node B (eNB) configured to communicate with a user equipment, a multiple frequency band indicator (MFBI) list, the multiple frequency band indicator (MFBI) list comprising at least one frequency band number listed in the same order of priority as broadcast by a target eNB. The method may further include selecting one of the at least one frequency band number for use by the source eNB, calculating a security key (KeNB*) using the DL EARFCN belonging to the selected frequency band number with the highest priority that is also supported by the user equipment, and signaling the calculated security key to the target eNB.

Abstract: Systems, methods, apparatuses, and computer program products for obtaining additional supported bands of neighbor cell(s) are provided. One method includes reading, by a user equipment, a frequency band list broadcast by at least one neighbor cell, and reporting the frequency band list to a cell serving the user equipment.
