Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Various communication systems may benefit from an improved signaling protocol. For example, communication systems may benefit from an improved network support for a narrowband internet of things in a hosting long term evolution carrier. A method, in certain embodiments, includes shifting a frequency of a downlink long term evolution channel by a pre-determined amount. The shift causes a duplex distance between the downlink long term evolution channel and an uplink long term evolution channel to change. The method includes blanking at least one overlapping radio resource in at least one of the uplink long term evolution channel or an uplink narrowband internet of things channel. The uplink narrowband internet of things channel and the uplink long term evolution channel at least partially overlap. In addition, the method includes receiving data on the uplink narrowband internet of things channel and an additional uplink narrowband internet of things channel at a network entity from a user equipment.

A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.
