Abstract: Various example embodiments relate to uplink synchronization. An apparatus may receive, from a device, an alert of expected expiry of at least one validity period of uplink synchronization data. In response to receiving the alert, the apparatus may pause scheduling of data transmissions for the device, or transmit, to the device, an on-demand uplink synchronization assistance signal comprising updated uplink synchronization data.

Abstract: Aspects and embodiments relate to an apparatus and method for evaluating location of a terrestrial network node in a non-terrestrial network. In particular, one aspect provides an apparatus, comprising means for receiving an indication of propagation delay between a terrestrial network node and a non-terrestrial node in a non-terrestrial wireless communication network; means for receiving an indication of location of the non-terrestrial node; and means for evaluating location of the terrestrial network node in dependence upon the received indication of propagation delay between the terrestrial network node and the non-terrestrial node, and the indication of location of the non-terrestrial node. A further aspect provides a method of evaluating location of a terrestrial network node, and a computer program product operable, when executed on a computer, to perform that method. Aspects and embodiments recognise that having a knowledge of gNB and NTN-GW location in a non-terrestrial network can allow UE to simplify procedures in relation to the updating and tracking of forward link delay. Since it has been agreed that a network will not directly provide the gNB and/or NTN-GW location to UE, due to security and privacy reasons in some countries, apparatus can be configured to perform methods according to which a UE is operable to calculate or obtain information which can assist its ongoing operation and reduce an ongoing need to decode SIB in support of calculation of an appropriate Uplink timing advance (TA) to apply in relation to communications exchanged with a network.

Abstract: Devices, methods and computer programs for synchronization information determination with respect to neighboring cells in wireless communications are disclosed. A network node device determines enhanced synchronization information related to neighboring cell(s) of a current cell served by the network node device. The network node device transmits the determined enhanced synchronization information via downlink signaling to at least one client device located in the current cell. A client device receives the enhanced synchronization information via the downlink signaling. The client device determines synchronization status data of the neighboring cell(s) with respect to the current cell based on the received enhanced synchronization information. The client device may perform an accelerated search for at least one of the neighboring cell(s) based on the determined synchronization status data.

Abstract: Embodiments of the present disclosure propose a solution for reporting with channel status waving. According to embodiments of this present disclosure, a terminal device determines one or more time durations for reporting and preconfiguring with the channel status waving. The terminal device transmits parameters related to channel status and/or adjusts its power in accordance with the one or more time durations. In this way, it can improve the reporting of channel status information and configuration efficiency with reduced overhead.

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.

Abstract: Systems, methods, apparatuses, and computer program products for management of updates in scheduling offset via system information and soft indication of system information modification are provided. For example, a method can include identifying, by a user equipment, a time of application of a new non-terrestrial-network system information. The method may also include waiting to apply the new non-terrestrial-network system information until the time of application. The method may further include applying the new non-terrestrial-network system information at the time of application, conditioned on the new non-terrestrial-network system information being received before the time of application.
