Claim of US Patent No. 10,993,233

1. An electronic device comprising:circuitry configured to
locate, within a wireless access interface provided by a base station, a narrowband carrier that includes a first plurality of resource elements across a first range of system resource blocks which is within and smaller than a second range of system resource blocks that span a system frequency bandwidth;
decode a narrowband carrier control portion within the narrowband carrier, the narrowband carrier control portion identifying resource elements within the narrowband carrier that are allocated to the electronic device;
locate the allocated resource elements within the narrowband carrier based on the decoded control portion; and
receive data transmitted by the base station by decoding the allocated resource elements within the narrowband carrier, wherein data transmitted on the narrowband carrier is logically distinct from data transmitted in remaining parts of the second range of system resource blocks.
