This document discloses a solution for addressing network slices in a radio interface between a station and an access node. According to an aspect, the station is granted access to a network slice and, when transmitting a data frame of the network slice, the network slice is identified in the data frame by a medium access control address of the data frame.

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.

Cooperative inter-network channel selection

According to an example aspect of the present invention, there is provided a method, comprising: transmitting, by a first transceiver of a first radio technology, wherein a first device comprises the first transceiver, a calibration start message to a second device, transmitting a calibration message by a second transceiver of a second radio technology, wherein the first device comprises the second transceiver, receiving channel state information, by the first transceiver from the second device, wherein the channel state information is based on reception of the calibration message, determining at least one coefficient for null steering towards the second device based on the channel state information, and transmitting a directional message to a third device, using the at least one coefficient.

Spatial reuse for wireless communications

A control-plane interface is established between a cellular radio access node and an anchor for at least first and second non-cellular radio access nodes (such as API and AP); and thereafter during mobility of a user equipment (UE) from API to AP, the anchor relocates a user-plane interface for a radio link allocated to the UE from API to APwhile maintaining the established control-plane interface for the radio link. When implemented for LTE-WLAN Aggregation (LWA), the control-plane interface is Xw-C with a corresponding control plane wireless termination (WT-C), the user-plane interface is Xw-U with a corresponding user plane wireless terminations (WT-U); the cellular radio access node is an eNB, the APs belong to the anchor and have BSSs that belong to a same mobility set that is configured for the UE by the eNB; the anchor is the WT-C, and the APs are WT-Us.

Various communication systems may benefit from traffic steering. For example, radio access network based traffic steering can be used to benefit of communications by steering traffic to Wi-Fi leveraging Hotspot 2.0. A method can include determining that an off-load condition exists in an area of a radio access network. The method can also include commanding a user equipment to off-load to non-cellular radio access based on the determining.

Radio access network based traffic steering to non-cellular access

A method, apparatus and computer program product are provided to facilitate the transition of user equipment between basic service sets within a WLAN or from a basic service set within a WLAN to a cellular data link of a cellular network. In the context of a method from the perspective of the user equipment, a message is received that identifies one or more basic service sets or cellular data links to which user equipment is potentially capable of transferring. For each basic set or cellular data link, the method includes determining from the message whether the respective basic service set or cellular data link is a candidate to permit an internet protocol (IP) address of the user equipment to be preserved following the transfer. The method includes an indication associated with each respective basic service set or cellular data link to identify whether the IP address of the user equipment is able to be preserved following the transfer thereto.

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.

There are provided measures for dynamic control of network selection. Such measures exemplarily comprise receiving a network list, said network list comprising at least one network discovery element, each of said at least one network discovery elements represents a particular network and comprises at least connection information for connecting to said network and a category assigned to said network, receiving a control signaling comprising at least one desired category, and selecting said network based on said at least one desired category and the category assigned to said network.

Dynamic control of network selection

An operator identity for an ANDSF management object is described. The operator identity identifies the server that originally provided the data concerned to the management object. In this way, it is possible to determine the operators that are responsible for different branches of an ANDSF management object. The operator identity may take the form of a PLMN identity.

Network selection mechanisms

Various embodiments are described relating to selecting anchor nodes among nodes in a wireless network. In an example embodiment, a topological arrangement of a first wireless node and one or more other wireless nodes neighboring to the first wireless node in a wireless network may be determined by the first wireless node. A second wireless node may be selected to perform anchor node operations for the first wireless node based on the determined topological arrangement. For example, the first wireless node may select itself to perform the anchor node operations based on the determined topological arrangement.

Anchor selection in distributed networks

A method comprising determining information for the performance of a channel and sending the determined information to a transmitter is disclosed. The determined information can be sent to the transmitter with acknowledgement data. The determined information can include, for example, data rate and/or transmit power. The acknowledgement data can be sent in an acknowledgement frame, such as a block acknowledgement frame or immediate acknowledgement frame. The determined information can be sent in the payload of the frame. The frame can, for example, be a kink feedback frame associated only with a particular transmitter and receiver. A characteristic of the channel, such as signal and interference to noise ratio, can also be determined.
