Abstract: Various communication systems may benefit from efficient communication of system information. For example, certain wireless communication systems may benefit from system information block enhancement for low complexity user equipment and/or user equipment in coverage enhancement mode. A method can include decoding a transport block size (TBS) index in a compact downlink control information. The method can also include monitoring for SIB based on the decoded TBS index. The method may optionally include monitoring for the SIB based on a predefined transmission pattern of physical downlink control channel for machine type communication. The method may also optionally include decoding of M-SI messages from a subframe according to a pattern indicated by an information element in M-SIB1.

Abstract: Systems, methods, apparatuses, and computer program products for paging of low complexity UE and/or UE in coverage enhancement mode are provided. One method includes producing a machine type communication (MTC) physical downlink control channel (M-PDCCH) configuration by configuring separate M-PDCCH subsets for paging. One of the subsets may be for low complexity user equipment, and another one of the subsets may be for user equipment operating in coverage enhancement mode.

Abstract: Systems, methods, apparatuses, and computer program products for random access procedure are provided. One method includes selecting, by a user equipment, a subframe for a first transmission of a preamble based on a configuration broadcast by an evolved node B (eNB). The method may also include repeating the preamble within a preamble repetition period based on a configuration broadcast by the eNB.
