Abstract: Various communication systems may benefit from improved network access. For example, communication systems may benefit from deriving a radio network temporary identification at both a user equipment and a base station, without requiring additional uplink signaling. A method, in certain embodiments, may include sending a short identification from a user equipment to a base station during a contention based access instance. The short identification is generated based on an initial cell radio network temporary identification. The method may also include receiving at the user equipment a user equipment radio network temporary identification from the base station. The user equipment radio network temporary identification is based on the short identification. In addition, the method may include generating at the user equipment a subsequent cell radio network temporary identification based at least on the short identification and the received user equipment radio network temporary identification.

Abstract: Devices, methods and computer programs for switching from a terrestrial cell to a non-terrestrial cell are disclosed. At least some example embodiments may allow switching a client device from a terrestrial cell to a non-terrestrial cell in such a way that the client device has time to prepare for the switch, and optionally perform tests related to a coverage of the non-terrestrial cell and inform a network node proposing the switch if the coverage is not sufficient. As a result, significant energy savings may be achieved on the network side, for example.

CPC classification number: H04W56/0045 , H04W84/06
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.

Abstract: Systems, methods, apparatuses, and computer program products for utilizing user equipment (UE) detection of radio state conditions. For example, certain embodiments may detect and utilize knowledge of periodic line-of-sight (LOS)/non-LOS (NLOS) radio state changes to improve a network's handling of such radio states. In particular, a UE may be configured to observe LOS/NLOS radio state transitions over time. The UE may generate an estimate of when periodic radio state changes have occurred. The UE may report a prediction of a future LOS/NLOS radio state change based on the estimates of when the previous radio state changes have occurred. The predictions may be reported to the network as a measurement report.

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.
