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.

Abstract: In accordance with some embodiments, a method may include transmitting, by a source network entity, at least one handover prepare request comprising at least one extension indication to a target network entity. The method may further include receiving, by the source network entity, in response to the at least one handover prepare request, at least one handover request response from the target network entity. The method may further include transmitting, by the source network entity, at least one handover command acknowledgement to at least one user equipment based upon the at least one handover request response.

Abstract: In a system, apparatus, method, and non-transitory computer readable medium for implementing fallback to conditional handover using a SSB reference signal, a UE device may be caused to, receive RRC reconfiguration information from a source RAN node, the RRC reconfiguration information including a SSB RS based CHO execution condition associated with at least one target cell controlled by a target RAN node, and a CSI-RS based CHO execution condition associated with the target cell(s), perform signal measurements of at least one SSB RS and at least one CSI-RS associated with the target cell(s), the at least one CSI-RS associated with a contention-free random access resource, and perform the CHO with the target cell(s) based on the signal measurement results of the at least one SSB RS, the at least one CSI-RS, the SSB based CHO execution condition, and the CSI-RS based CHO execution condition.

Abstract: There is provided an apparatus comprising means for: receiving, from a network node, at least one conditional primary secondary cell change and addition reconfiguration and at least one execution condition associated with at least one candidate primary secondary cell, wherein the reconfiguration comprises at least a new configuration for a master cell group; evaluating the at least one execution condition; determining that an execution condition associated with one of the at least one candidate primary secondary cell is satisfied; selecting the one of the at least one candidate primary secondary cell as a selected candidate cell; transmitting information on the selected candidate cell to the network node using a current master cell group configuration; failing to apply the conditional primary secondary cell change and addition associated with the selected candidate cell and detecting a reconfiguration failure; transmitting a message to trigger a re-establishment procedure, wherein the message comprises an explicit or implicit indication about the conditional primary secondary cell change and addition reconfiguration failure.

Abstract: Systems, methods, apparatuses, and computer program products relating to the coexistence of a first mode and second mode of vehicle-to-vehicle (V2V) communications. One method includes allocating, to a user equipment (UE) operating in a first mode of V2V communication that is also configured to use resources from a shared transmit (Tx) pool of a second mode of V2V communication, a pair of resources. The first of the pair of resources may be allocated from an exclusive Tx pool for the first mode, and the second of the pair of resources may be allocated from the shared Tx pool of the second mode of V2V communication.
