Abstract: An apparatus for use by a UE configured to conduct a communication in a communication network. The apparatus is configured to receive and process signals from the communication network via signal receiving portions, wherein one of the signal receiving portions is a serving cell signal receiving portion used for connecting to the communication network via a serving cell, and another of the signal receiving portions is a non-serving cell signal receiving portion being not used for connecting to the communication network. A signal receiving portion specific offset value is obtained for each of the signal receiving portions. Signal quality values for signals received by the signal receiving portions from the communication network are measured, wherein the cells include the serving cell. A measurement report is sent to the communication network on the basis of the results of the signal quality measurements and the offset values for the signal receiving portions.

Abstract: 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.

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: Systems, methods, apparatuses, and computer program products for conditional proactive discontinuous reception (DRX) measurement are provided. For example, a user equipment (UE) may be in a DRX active state (e.g., where the DRX is used) and configured to proactively measure for radio problems. Another example may relate to a network-controlled implementation where the serving network node (e.g., a base station (BS)) may signal the UE a condition and a configuration for the proactive DRX measurement. Another example may relate to a UE-controlled implementation for improving service unavailability using DRX operation. For example, the serving BS may signal, to the UE, proactive DRX measurement assistance information.

Abstract: Improved techniques of beam management in a HO situation include receiving, at a source node from a candidate target node after receiving a measurement report from a UE prior to completion of a HO, a repetition configuration of a channel state information reference signal (CSI-RS) resource index to be used by the UE for random access. When beam refinement occurs during HO, a candidate target cell for HO provides the UE with a repetition configuration of CSI-RS resource index that will be selected and used by the UE for random access to the target cell. When beam refinement occurs before HO, the candidate target cell of handover provides the UE (e.g. during the handover preparation phase in case of conditional HO (CHO)) with the repetition configuration of CSI-RS resource index (or indices) whose transmission(s) is repeated while the UE is served by the source cell and before executing a handover.
