Title:
OPERATIONAL METHOD FOR MTC DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/208940
Kind Code:
A1
Abstract:
Provided is an operational method for a machine-type communication (MTC) device. The operational method may comprise the steps of: if a bandwidth of a data channel has a reduced size in comparison to a bandwidth of a cell system, then determining the size of a precoding resource block group (PRG) with respect to the reduced bandwidth size of the data channel, instead of the bandwidth size of the system; and, if a bandwidth of a data channel has a reduced size in comparison to a bandwidth of a cell system, then determining the size of a sub-band for a channel quality indicator (CQI) feedback with respect to the reduced bandwidth size of the data channel, instead of the bandwidth size of the system.
