Abstract: A client device, a network node device, methods and computer programs are disclosed. A client device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the client device to receive a timing advance configuration message from a network node device, wherein the timing advance configuration message comprises a plurality of timing advance commands; perform a plurality of consecutive uplink transmissions to the network node device; and apply the plurality of timing advance commands between the plurality of consecutive uplink transmissions.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic cell-specific delay for timing scaling in a non-terrestrial network (NTN). For example, certain embodiments may utilize a cell-common delay composed of FL and part of SL (until a cell-specific reference surface). A network node (e.g., a gNB) may calculate the cell-common delay as a function of time (T_c(t)) and may provide this function to the UEs (the satellite path may beis deterministic). The function of time may be a combination of two functions representing the FL and SL. The function can may be broadcasted in a system information block (SIB) or transmitted directly to the UE through radio resource control (RRC) signaling when it becomes active, is handed over, and/or regularly updated.

Abstract: Systems, methods, apparatuses, and computer program products for mobility management in NR based non-terrestrial networks are provided. One method includes signaling geographical definitions of Geo-Areas (GAs) and/or an update to GA map to at least one user equipment (UE) in a network, and receiving a tracking area update (TAU) and/or radio access network (RAN)-based notification area update (RNAU) when the at least one UE detects a change in the at least one UE's GA location. The method may also include registering the change in the at least one UE's GA location, and configuring at least one of radio access network (RAN)-based notification area (RNA) or tracking area (TA) based on the registered change in the at least one UE's GA location.

Abstract: Aspects and embodiments relate to apparatus configured to delay execution of an action based on an execution delay and methods to delay execution of an action. In particular, the example embodiments provide apparatus and methods to delay execution of mobility related events, for example, handover. One aspect provides an apparatus, comprising: at least one processor; and at least one memory storing instructions that when executed by the at least one processor cause the apparatus at least to: obtain an indication of an execution delay to be applied by the apparatus in relation to an action to be executed by the apparatus, the execution delay being based upon one or more operational characteristic of the apparatus; determine that the action is to be executed by the apparatus; and delay execution of the action based on the execution delay. Arrangements and implementations provide a mechanism to mitigate RACH load congestion. Arrangements provide mechanisms to distribute a handover execution load (in the form, for example, of RACH attempts initiated by UE) across a restricted or limited time period.

Abstract: At a UE in wireless communication with a serving cell in a wireless network, the UE being configured with time-based conditional handover event trigger(s), receiving by the UE indication that the serving cell will be turning off. The UE determines relative timing of the time-based conditional handover event trigger(s) and timing based on the indication of the serving cell turning off. The UE determines whether the relative timing meets a criterion or criteria. The UE modifies, based on the relative timing meeting the criterion or criteria, mobility procedures for the UE that is in a connected state.

Abstract: Obtaining target cell ephemeris information for handover cases is provided. A method may be performed by a user equipment of acquiring, prior to initiating a handover, assistance information about each target neighboring cell in a list of candidate cells that is on the same satellite or a different satellite as a current cell to which the apparatus is currently connected. The handover may be performed from the current cell to one target neighboring cell from the generated list of candidate cells based on the assistance information.

Abstract: In a non-terrestrial network, the delay in reception time may prevent reception of a random access preamble. A combination of increasing transmit power and changing the timing with which the random access preamble is transmitted may enable reception of the random access preamble. One or more criteria may be used to determine whether the timing advance value with which the random access preamble is transmitted should be changed before retransmission is attempted.
