Abstract: According to an example embodiment, a client device comprises 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 ne processor, cause the client device to: detect need for random access, random access, in a non-terrestrial network to a target cell of the non-terrestrial network; identify whether the needed random access is intra-satellite or inter-satellite; in response to the needed random access being intra-satellite, perform a first random access procedure, wherein, in the first random access procedure, the client device transmits a random access preamble and a payload data in a single message; and in response to the needed random access being inter-satellite, perform a second random access procedure wherein, in the second random access procedure, the client device transmits a random access preamble and a payload data in separate messages. A client device, a network node device, methods and computer program products are disclosed.

Abstract: A method comprising, at a user device, comprising obtaining a target parameter representative of a handover rate from a base station, comparing said target parameter representative of a handover rate with a measured parameter representative of a handover rate, adjusting at least one measurement trigger event parameter as a result of said comparison in a direction tending to reduce the difference between said two rates, sending a measurement report to said base station if a trigger condition using said at least one adjusted trigger event parameter is met.

Abstract: Certain embodiments may relate to wireless communication systems. For example, some embodiments may relate to non-terrestrial networks (NTN). A method, in certain embodiments, may include receiving, by a user equipment (UE), at least one resynchronization message from at least one first network entity (NE). The method may also include resynchronizing, by the UE, with at least one second NE after at least one time period with at least one parameter based upon the at least one resynchronization message.

Abstract: Certain embodiments may relate to communication systems, and, for example, some embodiments may relate to multi-QoS level uplink grants. According to a first embodiment, a method may include transmitting, by a first network entity, one or more grants of one or more uplink resources to a second network entity. The one or more grants of one or more uplink resources includes one or more physical resource allocation parameters containing one or more logical channel groups. The method may further include receiving, by the first network entity, data from the second network entity allocated according to the one or more logical channel groups.
