Abstract:
Methods, systems, and devices are described for facilitating Machine Type Communication in a wireless communications system. Link budget-limited MTC devices, may be supported. An MTC physical broadcast channel may be utilized for the Machine Type Communication. The MTC physical broadcast channel may be transmitted over one or more subframes different from a regular physical broadcast channel. The payload for the MTC physical broadcast channel may be reduced. The MTC physical broadcast channel may also be utilized to indicate the presence of paging and/or to indicate a change in system information. Some embodiments utilize one or more MTC-specific system information blocks. The MTC-specific system information blocks may combine and/or simplify multiple system information blocks. The location of the MTC system information blocks may be predetermined or information about their location may be transmitted over the MTC physical broadcast channel. An enhanced paging channel may be used to indicate system information updates.
