1. User Equipment (UE) comprising processing circuitry to:
- operate, using a narrow bandwidth, in a wide bandwidth broadband network;
retrieve, from a downlink subframe, channels within a primary narrow bandwidth device region (NBDR), the primary NBDR being a subset of frequency resources within a wide bandwidth subframe, the primary NBDR being allocated within a central part of a signal spectrum in which primary synchronization signals (PSS) and secondary synchronization signals (SSS) are received, and the channels including a control channel;
process control channels in the primary NBDR, wherein the primary NBDR is received in a new carrier type (NCT) implemented in accordance with a standard of the 3GPP family of standards, retrieve, from the primary NBDR, configuration information for at least one secondary NBDR allocated in a different part of the signal spectrum separate from the central part of the signal spectrum, and wherein the PSS and SSS are not received in the secondary NBDR.

Abstract
Apparatuses and methods for supporting operation of narrow bandwidth devices within a broadband network are described herein. A user equipment (UE) may retrieve control channels within a narrow bandwidth device region of a downlink subframe. The control channels may be received in a subcarrier of a new carrier type (NCT) implemented in accordance with a standard of the 3GPP family of standards. Cell-specific reference signals may be excluded on the NCT subcarrier.

8. An evolved Node B (eNodeB) to communicate with a narrow bandwidth device in a wide bandwidth broadband network, the eNodeB comprising:
-
a configuration module arranged to configure a primary narrow bandwidth device region (NBDR) of a downlink subframe, and allocate a downlink control channel within the primary NBDR; and a transceiver module arranged to transmit the downlink subframe to the narrow bandwidth device on subcarriers of a first carrier type, wherein the first carrier type is a new carrier type (NCT) implemented in accordance with a standard of the 3GPP family of standards; transmit at least one secondary NBDR in a region separate from the primary NBDR; and transmit primary synchronization signals (PSS) and secondary synchronization signals (SSS) in the primary NBDR and refrain from transmitting PSS and SSS in the secondary NBDR. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for communicating with a narrow bandwidth device in a wide bandwidth broadband network, the method comprising:
-
configuring, at an evolved Node B (eNodeB), a primary narrow bandwidth device region (NBDR) of a downlink subframe, the primary NBDR being located in a central portion of a signal bandwidth spectrum in which primary synchronization signals (PSS) and secondary synchronization signals (SSS) are transmitted; configuring, at the eNodeB, a secondary NBDR in a different part of the signal bandwidth spectrum separate from the central portion and in which PSS and SSS are not transmitted; allocating, within the primary NBDR, an enhanced physical downlink control channel (ePDCCH); transmitting the downlink subframe to the narrow bandwidth device using subcarriers of a first carrier type, wherein the first carrier type is a new carrier type (NCT) implemented in accordance with a standard of the 3GPP family of standards; avoiding transmission of cell-specific reference signals (CRSs) on subcarriers of the first carrier type. - View Dependent Claims (16, 17, 18, 19, 20)
