    CPC classification number: H04W36/362

    Abstract: The present invention relates to survival time aware mobility and presents handover procedures when considering survival time (ST) requirements. It proposes a mechanism and embodiments to allow a target cell to have the information relating to a joining UE's Survival Time requirements as well as the ST status during the handover procedure. In particular, the invention is aimed at being introduced into the mobility procedures: Baseline Handover (BHO), Conditional HO (CHO), and Dual Active Protocol Stack (DAPS) HO. In addition to the aggregated RAN architecture, the mobility procedures can be applicable to disaggregated RAN architecture, e.g., CU-DU split.

    Abstract: Where a UE moves between primary and/or secondary cells, the repeated reconfiguration of a UE at the network requires repeated signalling. Where non terrestrial networks nodes provide cells it may be possible to predict which cells a UE is likely to visit and when, based on the satellite movement. Embodiments make use of this ability to predict multiple future cells by transferring configuration information for a series of target cells in a single message, in some cases along with condition information indicating when the cell is likely to be providing radio coverage for that UE. Furthermore, to reduce signalling overhead some of the information is provided as a delta information, that is as an indication of how a previous configuration will change to provide the new configuration. A UE can apply the configuration information as the conditions become fulfilled.

    IPC: H04W36/28

    CPC classification number: H04W36/28

    Abstract: An apparatus performs evaluating, with a user equipment of a communication network, before detaching from a source cell a conditional handover execution condition fulfillment for a conditional handover with the user equipment from the source cell to at least one target cell of the communication network; and based on the evaluating, detaching from the source cell for performing the conditional handover to a target cell of the at least one target cell. Further, an apparatus performs sending toward user equipment information comprising a configuration of a conditional handover, wherein the information causes the user equipment to evaluate a conditional handover execution condition fulfillment before detaching from the source cell for at least one target cell based on an indication of the conditional handover execution condition fulfillment to a first target cell of the at least one target cell that does not support a dual active protocol stack configuration.
