Abstract: The present invention solves some of the problems of the prior art by providing a method, system and apparatus for readily refilling the reservoir of a smoking-substitute device with liquid from a dispenser. The method, system and apparatus of the present invention prevents liquid from being dispensed until the dispenser is securely and sealably engaged to the smoking-substitute device, provides independent liquid and gas pathways between the dispenser and reservoir, and substantially alleviates the problems of spillage and/or leakage when dispensing liquid from the dispenser into the reservoir of the smoking-substitute device.

Abstract: A wireless backhaul link is established via a low-band frequency division duplex (FDD) carrier between an integrated access and backhaul (IAB) node and an TAB donor node or between the TAB node and another TAB node that is linked to the TAB donor node, in which the TAB donor node provides a backhaul connection to a core network of a wireless carrier network. Further, one or more corresponding wireless backhaul links are established between the TAB node and one or more additional TAB nodes via one or more corresponding low-band FDD carriers. When a user device is determined to be in range of the TAB node for an establishment of a wireless access link via a mid-band FDD carrier or a time division duplex (TDD) carrier, the wireless access link is established between the TAB node and the user device via the mid-band FDD carrier or the TDD carrier.

One or more corresponding backhaul links are established between the IAB node and one or more additional IAB nodes via a one or more corresponding NB-IoT or FDD carriers. A wireless access link is established between the IAB node and an NB-IoT user device or between the IAB donor node and the NB-IoT user device via an NB-IoT carrier. Additional wireless access links may be established between a wireless user device and the IAB node via at least one of a TDD, FDD, or NB-IoT carrier.

Abstract: This disclosure is directed to allocation of one or more radio bands to a user equipment (UE) for establishing a radio link with a radio node (e.g., eNodeB or gNodeB). The radio bands may include a shared band, such as citizens band radio service (CBRS), a primary licensed band, such as the B66 band, and/or an unlicensed band, such as B46 band. A radio communications system may consider a variety of parameters associated with the distance of a UE from a radio node, signal strength of a signal from the UE, the services requested by the UE, and/or spectral availability of the each of the radio bands to determine which radio band(s) to allocate to the UE. In some cases, the radio band allocated to a UE may be dynamically changed by the radio communications system as conditions related to the UE and/or the mobile network change.
