    Abstract: When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.

    Abstract translation: 当给定用户设备(UE)具有当前服务于其的多个K个小区时,在各种实施例中,存在用于触发UE无线发送小区测量报告的算法。 该算法利用其值取决于当前在UE的活动集中的小区的数量K的参数。 UE随时添加一个新的小区,或从UE的活动集中删除一个服务小区。 在各种示例中,参数是一个偏移量,这样一个偏移量使得为了增加一个新的单元格增加K的值,使得更难以满足该算法。 一个例子是使用由网络提供的斜率值和默认偏移值计算偏移值; 另一个具有使用由网络提供的K和偏移的最大和最小允许值计算的偏移值。

    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.

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.
