    Abstract: Embodiments of the present disclosure relate to device, method, apparatus and computer readable storage medium of serving cell change procedure utilizing the multiple candidate target cells. The method comprises receiving, from a second device, configuration information associated with a serving cell change procedure of the first device, the configuration information indicating at least a first candidate cell managed by a third device and a second candidate cell managed by a fourth device available for the serving cell change procedure; performing, during the serving cell change procedure, a first random access procedure to access the first candidate cell and a second random access procedure to access the second candidate cell; and accessing to a target cell determined from the first candidate cell and the second candidate cell after the serving cell change procedure is completed. In this way, the interruption time corresponding to CHO or CPC procedure when multiple candidates are available can be reduced.

    Abstract: A UE receives configuration from a source cell for conditional handover for target cell(s). At least one of the target cell(s) also supports DAPS handover. The UE determines that either a RLF or HOF has occurred. The UE selects one of the target cell(s) for a handover, and performs a process for handover to the selected target cell. A UE receives individual handover commands and corresponding configuration for conditional handover for target cell(s) and an indication to use DAPS handover if possible in response to a handover. The UE determined condition(s) for handover to one of the target cell(s) have triggered, wherein the one target cell supports DAPS handover. The UE performs, based on the indication to use DAPS handover if possible in response to a handover, handover by the user equipment to the one target cell without releasing the source cell while accessing the one target cell.

    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: 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: According to an example implementation, a method may include transmitting, by a user device to a base station in a wireless network, a system information request for on-demand system information during a random access procedure, where the system information request is a request for one or more parameters that enable the user device to communicate in the wireless network, receiving, by the user device from the base station, an indication of a wait period in which the user device waits before obtaining the on-demand system information, waiting, by the user device, a time duration during the wait period, and monitoring, by the user device after expiration of the wait period, a system information window in which a system information message having the on-demand system information is broadcasted by the base station.
