Apparatuses and methods for controlling measurements are disclosed. A message is received from a network element, the message including instructions to perform measurements of given carriers during given measurement gap pattern during next connection setup with the network. Connection setup is started with the network and the measurements of given carriers are performed during the given measurement gap pattern and measurement result reported to the network.

Controlling network measurements

Examples of the disclosure relate to an apparatus comprising means for: receiving configuration information to enable communication with a first node apparatus and with a second node apparatus, wherein the configuration information relates to split bearer communication; using the configuration information relating to the first node apparatus to communicate with the first node apparatus; storing the configuration information relating to the second node apparatus; and using the stored configuration information to switch from communicating with the first node apparatus to communicating with the second node apparatus if communicating with the first node apparatus has failed.

Fast master cell group (MCG) failure recovery

A method comprising, during multi-connectivity: sending a re-configuration message for execution by a user equipment; and sending a flag indicating an action to be taken by the user equipment during or after execution by the user equipment of an existing reconfiguration message, wherein the flag is configured to distinguish between at least two of the following actions: discarding the reconfiguration message; executing the reconfiguration message after executing an existing reconfiguration message; or prioritizing execution of the reconfiguration message over execution of an existing reconfiguration message.

Reconfiguration messages during multi-connectivity in wireless communication

A method including using master cell group resources for a downlink data transmission to a user equipment, wherein the user equipment is configured with at least one secondary cell group terminated split bearer and a secondary cell group is deactivated; determining, at a centralized central unit user plane, when secondary cell group resources of the deactivated secondary cell group are needed, wherein the determining is based, at least partially, on a data volume threshold for a data radio bearer as configured by a central unit control plane; and based upon the determining that the secondary cell group resources are needed, sending a notification to the central unit control plane to trigger activation of the secondary cell group resources.

Information exchange between the CU-CP and the CU-UP for flexible SCG (DE) activation

Systems, methods, apparatuses, and computer program products for beam tracking to reduce latency. A method may include receiving from a network node, a radio resource control reconfiguration message. The method may also include sending a radio resource control reconfiguration complete message in response to the radio resource control reconfiguration message. The method may further include performing radio resource management measurements according to information contained in the radio resource control reconfiguration message. In addition, the method may include preparing a measurement report based on the radio resource management measurements. Further, the method may include sending the measurement report to the network node. The method may also include maintaining a spatial relation with a cell or a carrier that is identified in the measurement report, as indicated in the radio resource control reconfiguration message.

Beam tracking for reduced latency

Inter-alia, a method is disclosed comprising: obtaining measurement configuration information indicative of a measurement configuration for a measurement on at least one target secondary cell of a mobile communication network, executing a handover to a target cell, and, before and/or during executing the handover, starting a measurement on at least one target secondary cell based, at least in part, on the measurement configuration information. Further, a method is disclosed comprising: receiving, from a target node, target secondary cell information indicative of at least one target secondary cell, upon reception of the target secondary cell information, transmitting a measurement configuration information indicative of a measurement configuration for a measurement on at least one target secondary cell based, at least in part, on the target secondary cell information. It is further disclosed an according apparatus, a computer program and a system.

Early measurements for PSCell addition after handover

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

Various example embodiments relate to signaling and execution of a handover based on an enhanced measurement report. A measurement report comprising an additional information element may be used by a network to make better and urgent decisions concerning handover procedures. Apparatuses, methods, and computer programs are disclosed.

Enhanced measurement report for conditional handover procedure

In accordance with some example embodiments, a method may include transmitting, by a network entity, at least one positioning measurement configuration associated with at least one radio access network notification area to a user equipment. The method may further include receiving, by the network entity, at least one location message. The method may further include transmitting, by the network entity, at least one location message response The at least one location message response comprises at least one last known location of the user equipment transmitted to the location management entity or at least one last location-associated measurement by the user equipment transmitted to the location management entity.

UE location tracking in an inactive state

According to a first embodiment, a method may include receiving, by a user equipment, at least one search threshold configuration. The method may further include determining, by the user equipment, at least one carrier measurement to perform according to the at least one received search threshold configuration. The method may further performing, by the user equipment, perform the at least one determined carrier measurement.

Carrier specific search thresholds

A UE in a wireless network determines whether it has been configured with carrier(s) to be used for secondary serving cell carriers in the wireless network. The UE performs, using a selected one of the carrier(s) as a selected secondary serving cell carrier, a request for a cell on the selected secondary serving cell carrier to become a secondary serving cell for the user equipment. The UE receives a response from the cell that the request to have the cell become the secondary serving cell for the user equipment was successful. The request is received on the carrier at a cell in the wireless network to have the cell become the secondary cell for the user equipment. The cell indicates to the UE that the request to have the cell become a secondary cell for the user equipment was successful.
