MTC DEVICE OPERATING IN ONLY PARTIAL BAND OF SYSTEM BAND OF CELL AND DOWNLINK CONTROL CHANNEL RECEPTION

Title:

MTC DEVICE OPERATING IN ONLY PARTIAL BAND OF SYSTEM BAND OF CELL AND DOWNLINK CONTROL CHANNEL RECEPTION

Document Type and Number:

WIPO Patent Application WO/2016/080772

Kind Code:

A1

Abstract:

The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is larger than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.
