Abstract  Abstract

Techniques for promoting machine type communication method in a wireless communication system a system and a device. can support limited link budget of the MTC device. can be used for machine type communication MTC physical broadcast channel. may be on one or more subframes of physical broadcast channel different from the conventional sending the MTC physical broadcast channel. it can reduce the payload for the MTC physical broadcast channel. also can use MTC physical broadcast channel to indicate a change in presence and/or indicating that the system information of the paging. Some embodiments use one or more MTC-specific system information block. These MTC-specific system information block can be used for combining and/or simplify the plurality of system information blocks. position of the MTC system information block can be predetermined or the information about the position of them can by MTC physical broadcast channel to send. can use enhancement type paging channel to indicate the updated system information.

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.
