Abstract

Provided is a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate only in a part of a band among system bands of a cell. A method for receiving a downlink control channel can comprise the steps of: determining a precoding matrix index (PMI) applied to a downlink control channel receivable only in a part of a band; receiving from a cell the downlink control channel in the part of the band in a data area of a subframe; and decoding the downlink control channel, which has been received from the cell, on the basis of the determined PMI.

Claims4

Dependent claims

A method for receiving a downlink control channel, the method performed by a wireless device and comprising:

monitoring the downlink control channel,
wherein the downlink control channel is repeated on a plurality of subframes for a coverage enhancement,
wherein one or more resource elements (REs), on which cell-specific reference signals (CRSs) are transmitted, are not used for a transmission of the downlink control channel,
wherein one or more resource elements (REs), on which synchronization signals are transmitted, are not used for the transmission of the downlink control channel,
wherein the downlink control channel is monitored in a common search space (CSS) within a narrowband,
wherein the narrowband for receiving the downlink control channel includes six maximum physical resource blocks (PRBs),
wherein the downlink control channel is transmitted based on a localized transmission mode or a distributed transmission mode,
wherein, within the localized transmission mode, the one or more enhanced resource element groups (EREGs) are transmitted in one physical resource block (PRB) pair to form an enhanced control channel element (ECCE) for the downlink control channel,
wherein, within the distributed transmission mode, the one or more enhanced resource element groups (EREGs) are transmitted in a plurality of PRB pairs to form the ECCE for the downlink control channel,
wherein the downlink control channel is an MTC physical downlink control channel (MPDCCH), and
wherein the distributed transmission mode is used for the CSS.
