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: A method, apparatus, and computer-program product are provided. In the context of a method, the method receives, from a first network node via a source satellite, a system information block, wherein the system information block indicates a random access channel opportunity window in which the user equipment should access the first network node or a second network node. The method includes determining, based on the system information block, an access time within the random access channel opportunity window. The method includes transmitting, to the first network node or the second network node via a target satellite, a random access channel preamble at the access time.

Abstract: A UE, connected using a current cell served by a first satellite to a BS, receives information from the BS including assistance information for a cell switch from the current cell to a cell served by a second satellite. The information is received before a stop time indicating when the current cell will stop serving the UE. The UE performs the cell switch from the current cell to the cell served by the second satellite using at least the assistance information to find cell synchronization block(s) for the served by the second satellite. The BS sends the information from the BS including the assistance information for a cell switch from the current cell to a cell served by a second satellite. The BS shuts down the current cell at a stop time.

Abstract: The present disclosure relates to on transition to another cell without handover in non-terrestrial network (NTN). In particular, a NTN device transmits information related to a set of NTN devices to a terminal a first device receives assistance information of a NTN device from a second device. The assistance information at least indicated a type of a cell switching. The first device skips buffer flushing and security key updating regardless of the type of cell switching. In this way, it can achieve cell switching without handover.

Abstract: An apparatus for a terminal device, the apparatus comprising at least one processor, and at least one memory storing instructions that, when executed by the at least one processor, cause the terminal device to: determine first information characterizing a difference between a first timing advance value associated with a first radio cell that is at least temporarily provided to the terminal device by a first device and a second timing advance value associated with a second radio cell that is at least temporarily provided to the terminal device by a second device, and to transmit the first information to a network device associated at least with the first radio cell.

Abstract: There is provided a method performed by a user equipment configured to operate in a non-terrestrial network, the method comprising: acquiring a scheduling offset value for communication between the apparatus and a first network node; determining a time difference between a reception of a downlink message and transmission of an uplink message, wherein the uplink message is transmitted in response to the downlink message; determining a time domain value based on the determined time difference and the acquired scheduling offset; and reporting the time domain value to a second network entity.

Abstract: An approach is provided for network-based positioning in non-terrestrial networks. The approach, for example, involves receiving a downlink position reference signal from a network node of a non-terrestrial network. The approach also involves determining whether the user device is in either line-of-sight or non-line-of-sight with respect to a network node of a non-terrestrial network. The approach further involves performing at least one of: (a) based on determining that the user device is in line-of-sight, transmitting a sounding reference signal for positioning to the network node; and (b) based on determining that the user device is in non-line-of-sight, transmitting the sounding reference signal for positioning to the network node for a number of repetitions.
