Abstract: 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.

Abstract: A method may include determining, by a base station, a switching occasion during which at least one connected user equipment will be in a connected off cycle and at least one idle user equipment will be in an idle off cycle, instructing the at least one connected user equipment and at least one idle user equipment to switch, during the switching occasion, from communicating with the base station via a source carrier frequency to communicating with the base station via a target carrier frequency, and switching, during the switching occasion, from communicating with the at least one connected user equipment and the at least one idle user equipment via the source carrier frequency to communicating with the at least one connected user equipment and the at least one idle user equipment via the target carrier frequency.

Abstract: Network nodes and methods for performing carrier aggregation in a wireless telecommunications network are disclosed. The method is for allocating resource blocks to support carrier aggregation communication between network nodes of a wireless telecommunications network and comprises: allocating first uplink resource blocks within at least one uplink band for use by an N uplink primary component carrier; and allocating second uplink resource blocks within at least one uplink band for use by at least one uplink secondary component carrier, the first uplink resource blocks allocated for use by the uplink primary component carrier being allocated from resource blocks within the at least one uplink band which are closer to resource blocks within at least one downlink band than the second uplink resource blocks allocated for use by the at least one uplink secondary component carrier.

Abstract: A method is provided of call setup between a calling terminal and a called mobile terminal. The calling terminal is in a first telecommunications network. The called mobile terminal has a home telecommunications network and roams in a second telecommunications network that is not its home network. The second network is for wireless telecommunications. The second network forwards information as to the location of the called terminal to the first network. The calling terminal receives information as to the location of the called terminal before call setup is completed.
