Abstract
According to one discourse of the present specification, a method for receiving information by a machine type communication (MTC) device is provided. The method of receiving the information may comprise the steps of: monitoring cell-specific control information within a common search space; and monitoring MTC device-specific control information within a UE-specific search space. Here, a resource region in which the common search space (CSS) is located and a resource region in which the UE-specific search space (USS) is located may be configured not to overlap each other.
Claims16
A method for receiving a downlink control channel, the method performed by a device and comprising:
- monitoring the downlink control channel within a common search space (CSS) or a machine type communication (MTC) specific search space;
- receiving downlink control information (DC), which is repeated over a first plurality of downlink subframes, via the downlink control channel;
- receiving a system information block (SIB) with a periodicity of 80 ms,
- wherein the SIB includes information dedicated for the device and is repeatedly received over a second plurality of downlink subframes within the 80 ms;
- based on that at least one first downlink subframe, among the first plurality of downlink subframes, is used to receive the SIB, determining that the DCI via the downlink control channel is not transmitted on the at least one downlink subframe,
- wherein the CSS includes a first CSS and a second CSS, based on a coverage enhancement (CE) mode;
- and
- decoding the DCI across the first plurality of downlink subframes between the SIB intervals within the search spaces of the second CSS and the MTC specific search space, based on the CE mode.
A device for receiving a downlink control channel, the device comprising:
- a transceiver;
- and
- a processor operatively connected to the transceiver and configured to:
- control the transceiver to monitor the downlink control channel within a common search space (CSS) or a machine type communication (MTC) specific search space,
- control the transceiver to receive downlink control information (DCI), which is repeated over a first plurality of downlink subframes, via the downlink control channel,
- and
- control the transceiver to receive a system information block (SIB) with a periodicity of 80 ms,
- wherein the SIB includes information dedicated for the device and is repeatedly received over a second plurality of downlink subframes within the 80 ms,
- wherein based on at least one first downlink subframe, among the first plurality of downlink subframes, is used to receive the SIB, the processor is configured to determine that the DCI via the downlink control channel is not transmitted on the at least one downlink subframe, and
- wherein the CSS includes a first CSS and a second CSS, based on a coverage enhancement (CE) mode, and
- control the transceiver to decode the DCI across the first plurality of downlink subframes between the SIB intervals within the search spaces of the second CSS and the MTC specific search space, based on the CE mode.
