Abstract: A method comprising configuring a narrowband internet of things carrier relative to one or more physical resource blocks of a radio carrier, the one or more physical resource blocks having a bandwidth that is greater than a bandwidth of the narrowband internet of things carrier; and configuring the narrowband internet of things carrier relative to the one or more physical resource blocks such that there is a first guard band between the narrowband internet of things carrier and a first adjacent physical resource block, and a second guard band between the narrowband internet of things carrier and a second adjacent physical resource block.

Abstract: This document discloses a solution for selecting a frequency channel for a service. According to an aspect, a method comprises: receiving, by a first access node of a first wireless network, a scanning message comprising at least one information element indicating a channel access limit for a frequency channel operated by a second access node of a second wireless network; selecting, by the first access node on the basis of the at least one information element, the frequency channel or another frequency channel for an ultra-reliable low-latency (URLLC) service provided by the apparatus; and upon selecting the frequency channel for the URLLC service, causing by the first access node transmission of frames of the service within channel access limits indicated by the at least one information element.

Abstract: A method and apparatus can be configured to attach to a first network. The first network may use a first radio-access technology. The method may also comprise connecting to a second network. The second network may use a second radio-access technology. The method may also comprise transmitting an identifier to the second network. The identifier may relate to a first network node of the first network to which the apparatus may be attached.

Abstract: There is provided a method comprising controlling receiving, at a user equipment, access information from a first network, said access information associated with a second network, the first and second network using different radio access technologies and using said access information in communication with the second network.
