Abstract: According to an example embodiment, a client device comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the client device to: receive a measurement configuration from a first network node device, receive a preconfigured condition for the measurement configuration from the first network node device, and in response to the preconfigured condition for the measurement configuration being fulfilled, use the measurement configuration. A client device, a network node device, methods, and computer programs are disclosed.

Abstract: Improved techniques of managing measurement gaps for MPUEs include identifying an idle time for the UE in a coordinated and network-controlled manner during which the UE is able to perform SSB/CSI-RS based measurements for a serving cell using non-serving panels. Such idle time is defined as an omitted operation time (i.e., an idle time of a certain pre-defined length) in which the network has to apply the scheduling restrictions in the SSBs' symbols to the UE. Note that currently as per the RAN4 requirements, the network must apply scheduling restrictions in all SSB symbols for all UEs in FR2 at any time (i.e., worst case scenario).

Abstract: 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.

Abstract: An apparatus suitable for at least to: receive, from a serving access node, a random access update precondition and a configuration with regard to a conditional handover, wherein the configuration indicates at least one handover candidate cell; carry out measurements according to the configuration, and if the random access update precondition is fulfilled, transmit a message to the serving access node, the message comprising information obtained by the measurements and indicating at least one beam of at least one handover candidate cell and/or at least one handover candidate cell that caused the random access update precondition being fulfilled for obtaining a random access resource configuration for carrying out the conditional handover.

Abstract: A source network apparatus (10) which provides access for a user equipment (30) to a communication network transmits (S102) a handover command to the user equipment (30), the handover command indicating a target network apparatus (20) for providing access for the user equipment (30) to the communication network, and a detach condition on when the user equipment (30) is to detach from the source network apparatus (10) after having accessed the target network apparatus (20) (S204) and received user plane data packets from the target network apparatus (20) (S205), wherein the source network apparatus (10) continues exchanging user plane data packets with the user equipment (30) (S101, S103) until the user equipment (30) detaches (S306) from the source network apparatus (10).

Abstract: An example embodiment relates to Random Access Channel, RACH, procedure, for example in the New Radio, NR. Random access procedures may be of two types, contention based CBRA and contention free, CFRA. A client device may only perform CBRA fallback when none of the reference signal received strengths, RSRPs, of the synchronization signal blocks, SSBs, which is associated with the CFRA resources is above a predefined threshold, T1. All SSBs and CSI-RS with associated CFRA resources may be below the threshold. Then, the client device may select an SSB or CSI-RS according to a predefined rule and perform CFRA when CFRA resources are associated. Devices, methods and computer programs are disclosed accordingly.

Abstract: Systems, methods, apparatuses, and computer program products for configuring Channel State Information-Reference Signal (CSI-RS) resources of neighboring cells for inter-cell mobility are provided. One method may include providing, by a network node, at least one reporting configuration to one or more user equipment. The reporting configuration is based on at least one of channel state information reference signals (CSI-RS) or synchronization signal/physical broadcast channel (SS/PBCH) blocks. The method may also include receiving at least one measurement report comprising measurement results when and as specified by the at least one reporting configuration.

Abstract: There is provided a method comprising: upon detecting that a first condition is met, causing a transmission of a measurement report to a wireless network; acquiring a conditional handover command from the wireless network; upon detecting that a second condition, associated with the conditional handover command, is met, starting a handover execution timer for triggering execution of a handover from a source cell to a target cell; detecting that a radio link failure condition is met before the execution of the handover is triggered; and on the basis of the detecting, signaling, to the wireless network, information indicative of a cause of a conditional handover failure to be either misconfigured first condition or misconfigured second condition.

Abstract: Various communication systems may benefit from improved handover. For example, it may be helpful to manage a list candidate cells to which a user equipment may be handed over. A method may include receiving at a user equipment a list of prepared candidate cells from a source cell. The method may also include transmitting the list of prepared candidate cells from the user equipment to a target cell after or during handover from the source cell to the target cell.
