A method comprising: configuring a user equipment in a low activity state to operate according to a grant-free uplink transmission scheme; and in response to detecting at least one condition, scheduling a discontinuous reception state at the user equipment, during which the user equipment is configured to monitor for one or more messages intended for the user equipment.

Reception scheme

A method for positioning in a sidelink communication. The method includes detecting, by an anchor component, a presence of at least one user equipment; and activating, by the anchor component, a transmission of a positioning reference signal to the user equipment responsive to the detected presence of the at least one user equipment.

Transmission of positioning reference signals for sidelink communications

Disclosed is a method comprising providing a primary cell capable of serving a terminal device; determining a candidate secondary cell group, comprising one or more cells that have coverage area within the coverage are of the primary cell; determining, from the candidate secondary cell group, a cell that, based on information obtained before or during a connection setup signalling, has the highest probability of being successfully configured as a secondary cell for an inter-site carrier aggregation for the terminal device; and configuring the cell as the secondary cell for the inter-site carrier aggregation.

Enhanced blind configuration of a cell

It is provided a method, including providing location information indicating a location of a terminal to a radio-independent localization and tracking system; evaluating at least one of environmental information and tracking information received from the radio-independent localization and tracking system with respect to the terminal in response to providing the location information; managing a resource for serving the terminal based on the at least one of the environmental information and the tracking information, wherein the environmental information includes information about an environment of the terminal, and the tracking information includes information about a track of the terminal.

Optimizing resource of a terminal allocation by computer vision

For example, a communication link between a first relay node and a second relay node, which are in synchronous movement, is established. Beam management assistance information from the first relay node is received at the second relay node upon an occurrence of beam failure at the first relay node (S). At the second relay node it is decided about a timing at which the received beam management assistance information is to be transmitted to a serving network node (S), and the received beam management assistance information is transmitted from the second relay node to the serving network node at the decided timing (S).

Enhanced beam management for high speed networks

An apparatus comprising means configured to: manage at least one location request for at least one user equipment based on an indicator indicating whether a node associated with the location determination for the at least one user equipment is tracking the location for the at least one user equipment.

Apparatus and method to indicate whether a node is tracking the location of a user equipment

An apparatus comprising means for performing: receiving, while connected to a first cell, preparation information for preparing the apparatus for a conditional handover of the apparatus to at least one other cell; receiving, from the first cell, a message, wherein the message causes the apparatus to transition from a connected state to an inactive state; receiving, from the first cell, information of a release condition; when it is determined that the release condition is met, sending a release indication and releasing the preparation information from the apparatus.

Signalling improvement in conditional handover

A PCell for a UE participates in a first phase to add a PSCell to a set of cells including the PCell to be used by the UE for a MCHO, comprising determining that the UE is to participate in the MCHO, and sending indications of at least resources for selected ones of multiple candidate cells toward the UE for use for the MCHO. The PCell participates in a second phase to add the PSCell to the set, comprising determining by the PCell which of the selected multiple cells has been accessed by the UE as the PSCell. The PCell participates in a swap from being the PSCell for the UE to becoming a current PSCell for the UE, wherein the PSCell is swapped from the PSCell to being a current PCell for the UE. The current PSCell participates in a release of a connection to the UE.

Two-step addition of a primary-secondary cell, PSCell, in a multi-connected handover

In accordance with some embodiments, a method may include receiving, by a first network entity, at least one user equipment context modification request from a second network entity. The method may further include configuring, by the first network entity, at least one of one or more unicast channels and one or more multicast channels. The method may further include receiving, by the first network entity, multicast data. The method may further include selecting, by the first network entity, at least one of one or more multicast channels and one or more unicast channels to transmit multicast data.

Method of multicast data delivery in 5G supporting cloud architecture

There is provided a solution for proactively transferring downlink data addressed to a terminal device from a data routing network element of a cellular communication system. According to an embodiment, a location of the terminal device is determined and an identifier associated with the determined location is delivered to the data routing network element. Then, the data routing network element may forward the downlink data towards the terminal device even before one or more services for the delivery of the downlink data to the terminal device have been completed.

Data routing in cellular communication system

A technique includes transmitting a request for the delivery of multicast data; receiving the multicast data via a unicast data radio bearer or a multicast data radio bearer, wherein the user device is located in a first cell; receiving, by the user device from the base station, a connection suspend message, wherein the connection suspend message includes: information describing a radio access network (RAN) multicast area (RMA) for the delivery of the multicast data via a multicast data radio bearer, and a group identifier associated with the multicast data, wherein the RMA includes a list of one or more cells that has been updated by the base station to include the first cell where the user device is located; entering, by the user device, a low activity state in response to the connection suspend message; and, receiving, by the user device, the multicast data via the multicast data radio bearer.

Multicast traffic area management and mobility for wireless network

According to an example aspect of the present invention, there is provided a method, comprising: storing a security context comprising a first key for wireless data transmission, and applying a timer for defining validity of the security context for the data transmission during an inactive state.
