Abstract: Example embodiments of the present disclosure generally relate to methods, devices, apparatuses and computer readable storage medium for cell reselection requirements with satellite prioritization. The method includes determining at least one first candidate satellite currently available for a neighbor cell measurement; determining at least one target satellite to be measured in the neighbor cell measurement at least based on the number of the at least one first candidate satellite and respective priorities of the at least one first candidate satellite, or at least one second candidate satellite that is becoming available within a first time interval; and performing the neighbor cell measurement on the at least one target satellite.

Abstract: Example embodiments of the present disclosure relate to apparatuses, methods, devices, and computer readable storage medium for a transmission of a channel state information reference signal (CSI-RS). In a method, a first apparatus receives, from a second apparatus, a configuration of discontinuous transmission (DTX) of the second apparatus. The first apparatus transmits, to the second apparatus, a request for a transmission of a CSI-RS during at least one non-active period of the DTX.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for conditional link synchronization in non-terrestrial networks. In example embodiments, a first device detects system broadcasted information, if there is data to be transmitted from the first device to the second device. Alternatively, the first device detects system broadcasted information if the first device receives a request for synchronization information from the second device. If the first device receives the system broadcasted information, it generates the synchronization information based on the system broadcasted information. Further, the first device transmits the synchronization information to the second device.

Abstract: Example embodiments generally relate to devices and methods for remapping of paging subgroups. A user equipment (UE) device may be configured to receive from a base station an explicit or implicit indication of remapping between one or more first scheme paging subgroups and one or more L1 paging subgroups, remap a first scheme paging subgroup of the UE device to a L1 paging subgroup based on the received indication of remapping, monitor for a paging early indication (PEI) from the base station including an indication of the remapped L1 paging subgroup, and receive a paging message from the base station based on the PEI.

Abstract: To increase accuracy of a reference clock based on which reception occurrences are monitored, a specific signal sequence for a wake up signal is used. The specific signal sequence comprises a blank symbol followed by a synchronization sequence for which a reference value is counted and a target value determined. At least frequency of the reference clock is adjusted based on the reference value and the target value.

Abstract: Embodiments of the present disclosure relate to conditional handover. A method comprises: upon a successful handover to a first target cell in an ordered list of target cells configured for a terminal device to initiate handover in order, determining, at the terminal device, information for assessing a validity of the ordered list; and transmitting, to a first network device providing the first target cell, a first message comprising the information for assessing the validity of the ordered list. In this way, a chain of target cells is capable of preparing for the future handover from the suitable time, which avoids reserving resources too early or too late and improves the resource efficiency. Moreover, the current serving cell can detect the deviation of the terminal device from the chain in time, thus a configuration of the ordered list can be appropriately adjusted or updated.

Abstract: Devices, methods and computer programs for avoiding unnecessary radio measurement gaps in a non-terrestrial network are disclosed. At least some example embodiments may allow replacing an unused radio measurement gap with an option of scheduling to improve network scheduling flexibility, user throughput and/or latency, and client device battery life.

Abstract: Apparatus and method for communication in non-terrestrial networks are provided. Downlink transmissions are received (400) from one or more non-terrestrial nodes. Signal strengths and/or signal quality of the transmissions are measured (402) from the one or more non-terrestrial nodes. Transitions between line-of-sight and non-line-of-sight states regarding the one or more non-terrestrial nodes are determined (404). Locations of the one or more non-terrestrial nodes and the apparatus are determined (406) and elevation and azimuth angles to the one or more non-terrestrial nodes from the apparatus are calculated (408). A database of the line-of-sight and non-line-of-sight states is generated (410) as a function of elevation and azimuth angles and apparatus location and utilised (412) to determine expected line-of-sight and non-line-of-sight states for non-terrestrial nodes.

Abstract: This document discloses a solution for performing a random access procedure. According to an aspect, a method for a terminal device comprises: receiving, from an access node, system information comprising a first random access configuration and at least a second random access configuration; determining, whether a link loss between the terminal device and the access node is increasing or decreasing; if the link loss is determined to decrease, selecting the first random access configuration and performing the random access with the access node by using the first random access configuration; and if the link loss is determined to increase, selecting the second random access configuration and performing random access with the access node by using the second random access configuration.
