Methods and apparatus for managing machine-type communications
The described aspects include methods and apparatus providing MTC in a wireless network. In an aspect, a narrow bandwidth within a wide system bandwidth is allocated for communicating data related to MTC. MTC control data generated for communicating over one or more MTC control channels for an MTC UE within the narrow bandwidth is transmitted over the one or more MTC control channels. The one or more MTC channels are multiplexed with one or more legacy channels over the wide system bandwidth. Other aspects are provided for transmission mode and content of the MTC control data or other MTC data.
