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: Aspects of the present invention pertain to a method, comprising receiving a preparatory handover request pertaining to at least one or more physical resources, respectively associated to a particular communication service, preliminarily deciding on the feasibility of such preparatory handover request for each of said at least one or more physical resources associated to the particular communication service dependent on at least one feasibility criterion, and validating the preliminary decision on the feasibility of the preparatory handover request dependent on at least one validation criterion. Likewise, corresponding apparatus and computer program products are addressed, both from network entity perspective such as a gNB, as well as from a terminal's perspective, e.g. from a UE perspective.

Abstract: A UE, in response to a beam failure being detected for a serving cell that serves the user equipment, determines whether a timer is running. One of the following is performed by the UE: in response to the timer running, a beam failure recovery procedure with a target non-serving cell; or in response to the timer not running, a beam failure recovery procedure with the serving cell. Methods, apparatus, computer programs, and computer program products are disclosed.

Abstract: There are provided measures for enabling/realizing load balancing between neighboring cells in a system with beamformed radio access. Such measures exemplarily include determining a load balancing condition, including at least one beam as a candidate beam and at least one target radio access entity for offloading terminal entities being currently served by the candidate beam, specifying a load balancing hypothesis for a hypothetical case of deactivation of the candidate beam, including information on an impact of the hypothetical beam deactivation, inquiring non-/acceptance of deactivation of the candidate beam from the at least one target radio access entity on the basis of the load balancing hypothesis, and deactivating the candidate beam if acceptance of deactivation of the candidate beam is inquired from the at least one target radio access entity.

Abstract: Systems, methods, apparatuses, and computer program products for source cell to provide a service/slice indication to the target cell in the handover preparation. The source cell provides to a target cell a list of one or more service/slice specific indications for individual ones of one or more network slices in a request for enhanced handover from the source cell to the target cell in a handover preparation phase. The source cell receives from the target cell, indications in a handover request acknowledgement of one or more selected network slices to be handed over from the source cell to the target cell using enhanced handovers. Performs make-before-break handovers to hand over these selected network slices from the source cell to the target cell and performs normal handovers for the one or more other network slices.

Abstract: Certain example embodiments provide systems, methods, apparatuses, and computer program products for a handover of a coordinated multi-point connection. For example, certain embodiment may transfer a first coordinated multi-point connection (e.g., a further enhanced multiple input multiple output (FeMIMO) connection) to a second coordinated multi-point connection where the network may instruct the UE to not perform at least one random access procedure. The first coordinated multi-point connection may be controlled by a first cell (the serving cell) where the UE is ready to receive from and transmit to a first set of cells that comprises the serving cell and one or more non-serving cells. After handover, the second coordinated multi-point connection may be controlled by a previous non-serving cell, and the UE may be ready to receive from and transmit to a second set of cells that comprises the previous non-serving cell.
