Claim of US Patent No. 10,462,779

1. A machine-type communication (MTC) device configured to:communicate data via a wireless access interface, wherein the wireless access interface includes at least 1200 subcarriers and the MTC device is only configured to communicate data over a bandwidth equal to or less than 72 subcarriers;
receive, in a reduced bandwidth carrier formed of a first subset of 72 or fewer subcarriers of the 1200 subcarriers in a first sub-frame, allocation information comprising an indication of a location of common information for the MTC device within a first carrier formed of a second subset of 72 or fewer subcarriers of the 1200 subcarriers that do not overlap a frequency range of the reduced bandwidth carrier in a second sub-frame that immediately follows the first sub-frame; and
access the common information in the first carrier of the second sub-frame based on the allocation information included in the reduced bandwidth carrier of the first sub-frame,
wherein the common information comprises a first portion including information that is accessible by devices using the first carrier and devices using the reduced bandwidth carrier, a second portion including information that is accessible only by one or more devices using only the first carrier, and a third portion including information that is accessible only by one or more devices using only the reduced bandwidth carrier, wherein a first set of resources allocated to the first portion is greater than a second set of resources allocated to the second portion, and the second set of resources is greater than a third set of resources allocated to the third portion, and wherein amounts of each one of the first, second, and third set of resources are dependent on one another.
