Example Embodiment
[0049] The invention designs a physical downlink control channel specially used for MTC terminals, and allocates a dedicated physical downlink control channel for MTC on the original LTE carrier. The present invention will be described in detail below with reference to the drawings.
[0050] Such as figure 2 As shown, the embodiment of the machine terminal communication method of the present invention includes the following steps:
[0051] Step 102: The base station (eNB) generates an MIB containing physical downlink control channel configuration information;
[0052] The physical downlink control channel is a physical downlink control channel dedicated to machine type communication. For example, the physical downlink control channel occupies the kth to k+y symbols of the xth subframe in the time domain, and occupies z subcarriers in the frequency domain. , X, k, y, z and other information need to be transmitted through the MIB of the carrier. Add x, k, y, z and other information t...
