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: 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.

Abstract: A method may include sending, by a user equipment, a random access preamble message to a network element. The method may also include receiving an uplink grant in a random access response message in response to the random access preamble message. The method may further include adding an implicit timing advance offset to an uplink time domain resource allocation of the uplink grant to establish synchronization of radio transmissions between the user equipment and the network element. The method may also include transmitting a scheduled transmission message including the implicit timing advance offset to the network element. Further, the implicit timing advance offset may be added to the uplink time domain resource before the scheduled transmission message is transmitted.
