Method and MTC device for receiving downlink channel

A machine type communication (MTC) apparatus for monitoring downlink control channels, comprising:

• a transceiver;
• and
• a processor for controlling the transceiver, wherein the processor is configured to perform:
• receiving a first configuration information indicating a first sub-band within a system band of a cell,
• wherein the first sub-band is used to monitor a first downlink control channel in a first search space (SS) and to receive a first downlink data channel scheduled by the first downlink control channel in the first SS,
• switching from the first sub-band indicated by the first configuration information to a second sub-band;
• not receiving a signal on at least one or more front orthogonal frequency-division multiplexing (OFDM) symbols among a plurality of OFDM symbols in a subframe, during the switching;
• and
• monitoring a second downlink control channel in a second SS within the second sub-band.
