Transmitting system information change notifications to mtc devices

At least one machine readable storage medium having instructions embodied thereon for communicating system information change notifications from an eNodeB to a machine type communication (MTC) device, the instructions when executed perform the following:

• detecting, using at least one processor at the eNodeB, that a change has occurred in one or more system information blocks (SIBs) with respect to a previous version of the one or more SIBs;
• communicating, using the at least one processor at the eNodeB, a system information (SI) change notification to the MTC device that indicates a change has occurred in the one or more SIBs;
• communicating, using the at least one processor at the eNodeB, a bitmap that indicates which of the one or more SIBs includes a change with respect to the previous version of the SIB;
• and
• communicating, using the at least one processor at the eNodeB, a SIB1 to the MTC device that includes scheduling information for a plurality of SIBs, wherein the MTC device is configured to obtain scheduling information from the SIB1 for the one or more SIBs that include a change according to the bitmap when a value tag associated with the SIB1 does not equal to a value tag stored at the MTC device, wherein the MTC device is configured to retrieve the one or more SIBs that include a change using the scheduling information obtained from the SIB1.

An apparatus of a user equipment (UE) operable to receive system information change notifications from an eNodeB, the apparatus comprising one or more processors and memory configured to:

• receive, at the UE from the eNodeB, a system information (SI) change notification that indicates a change has occurred in one or more system information blocks (SIBs) with respect to a previous version of the one or more SIBs, wherein the SI change notification includes a bitmap that indicates which of the one or more SIBs includes a change with respect to the previous version of the SIB;
• receive, at the UE, a SIB1 that is broadcast from the eNodeB, wherein the SIB1 includes scheduling information for a plurality of SIBs;
• compare a value tag associated with the SIB1 with a value tag stored at the UE;
• obtain, from the SIB1, scheduling information for the one or more SIBs that include a change according to the bitmap when the value tag associated with the SIB1 does not equal to the value tag stored at the UE;
• and
• retrieve the one or more SIBs that include a change using the scheduling information obtained from the SIB1.
