Abstract: In this invention, when a serving distributed unit informs target distributed unit via a central unit about a target reference, it is proposed to use, signal index X/indices X1 . . . Xn for PDCCH transmissions or PUSCH receptions or a RACH-less handover:
Send by a distributed unit of the serving cell towards a distributed unit of a target cell one of before, upon, or after transmission of a layer 1 serving cell change command to a user equipment, signaling comprising configuration information associated with the user equipment to perform a random access channel less handover of the user equipment to the target cell, wherein the configuration information informs the target cell about at least one target reference signal index that shall be used for at least one of at least one physical downlink control channel transmission or at least one physical uplink shared channel reception.-

Abstract: There is herein disclosed a method for receiving, from a radio access network node, a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of the UE for a plurality of target cells. The method further comprises receiving, from the radio access network node, an indication that the UE is allowed to select and connect to a preferred target cell from the plurality of target cells. The method further comprises selecting the preferred target cell from the plurality of target cells based on network slice area of service availability information for each target cell configured at the UE and the radio condition and transmitting, a request to connect to the preferred target cell.

Abstract: A user equipment (UE) includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the UE to obtain a conditional handover command, the conditional handover command indicating a multiple cell target for handover from a source cell and at least one performance margin, each of the at least one performance margin associated with a cell neighboring a first cell in the multiple cell target, determine whether to initiate a handover to the first cell based on the at least one performance margin, and transmit data to the first cell based on the determination of whether to initiate the handover.

Abstract: A method is disclosed, e.g. performed by a user equipment, the method comprising: establishing a connection to a first master node, receiving a first reconfiguration message including configuration information for a secondary node addition including a first key, performing a random access to the secondary node, transmitting and/or receiving data towards/from the secondary node on one or more secondary cell group bearers using the first key, receiving a second reconfiguration message relating to an inter-master node handover from the first master node to a second master node, the reconfiguration message comprising configuration information relating to a dual active protocol stack (DAPS) for one or more secondary cell group bearers associated with the secondary node and a second key; establishing the dual active protocol stack for the one or more secondary cell group bearers of the secondary node based on the configuration information; transmitting and/or receiving data towards/from the secondary node on the one or more secondary cell group bearers using the first key hosted by the dual active protocol stack for the one or more secondary cell group bearers; performing a random access to the second master node; transmitting a reconfiguration complete message to the second master node; and transmitting and/or receiving data towards/from the secondary node for the one or more secondary cell group bearers using the second key hosted by the dual active protocol stack for the one or more secondary cell group bearers. Related methods that may be performed by network nodes are disclosed. Further, a corresponding system and corresponding apparatuses, computer programs, and computer-readable storage media are disclosed.

Abstract: Techniques of cell change in a SCO DEACTIVATED state includes a master node configuring a user equipment with a partial Conditional PSCell Addition Change (CPAC) which only contain the configurations relevant for common channel access without any dedicated configurations. The improved technique proposes a modified CPAC configuration procedure to reduce the overall signalling messages and frequency of network communication, involved in UE switching between SCGs in SCG-DEACTIVATED state.

Abstract: Techniques for coordination between nodes for measurement configuration in a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure in cellular wireless communication networks are provided. For example, a method for a Primary Secondary Cell Group (SCG) Cell (PSCell) change procedure is provided. The method comprises: sending, from a master node (MN) to a target secondary node (T-SN), a first message (e.g., an SN Addition Request message) including configuration information based on which the T-SN determines whether to provide a full configuration or a delta configuration for measurement-related information for one or more candidate target PSCells acknowledged by the T-SN; and receiving, at the MN from the T-SN in accordance with the configuration information, a second message (e.g., an SN Addition Request Acknowledge message) including the full configuration or the delta configuration for measurement-related information for the one or more candidate target PSCells acknowledged by the T-SN.

Abstract: There are provided measures for enabling/realizing an early evaluation for conditional reconfiguration in a mobile/wireless communication system. Such measures exemplarily include that a communication entity obtains an evaluation measurement configuration and an evaluation candidate cell set, performs an evaluation measurement in accordance with the evaluation measurement configuration on the evaluation candidate cell set, and performs or starts evaluating an execution condition for conditional reconfiguration for the evaluation candidate cell set on the basis of a result of the evaluation measurement, in the absence of and/or prior to availability of an actual configuration for conditional reconfiguration.

Abstract: Systems, methods, apparatuses, and computer program products for reducing handover interruption time using sidelink communication are provided. For example, the handed-over (remote) user equipment may exchange uplink and downlink data with the target cell via the additional or assisting link to another relay user equipment while the remote user equipment performs the random access procedure (random access channel procedure) and may establish its own direct radio link to the target cell.
