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: Embodiments of the present disclosure relate to devices, methods, apparatuses, and computer readable storage media of enhanced UL synchronization for improved system performance. The method comprises obtaining a configuration of a gap within which a radio resource control connected state of the first device is kept; receiving, within the gap, system broadcasted information used for deriving a compensation associated with a transmission between the first device and a second device; and performing a uplink synchronization between the first device to the second device within the gap. In this way, a process of the GNSS fix position refreshing and/or satellite ephemeris data reception and UL/DL re-synchronization can be achieved by the UE in RRC connected mode and therefore the resources and power consumption can be reduced.

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: Disclosed are methods for configuring measurement gap patterns. An example method may include: receiving configuration information associated with a plurality of pre-configured measurement gap patterns; receiving index information for configuring at least one measurement gap pattern of a bandwidth part; and configuring the at least one measurement gap pattern of the bandwidth part based on at least one of the configuration information and the index information. Related apparatuses and computer readable media are also disclosed.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for a handover to dual connectivity. According to embodiments of the present disclosure, a terminal device receives, from a source network device, a connection reconfiguration message comprising configurations about a target master network device and a target secondary network device to be connected with the terminal device. The terminal device performs parallel random access to the target master network device and the target secondary network device. If the terminal device successfully connects to the target secondary network device but fails to connect to the target master network device, the terminal device will reconnect to the target master network device. In addition, the target secondary network device will indicate to the target master network device a result of the random access. As such, the solution can increase the success rate of the handover to dual connectivity.

Abstract: Embodiments of the present disclosure relate to dynamic active time trigger in CFRA. A first device receives a random access request from a second device in a discontinuous reception mode. The first device transmits a random access response to the second device. The random access response comprises at least one of: an indicator of an offset between a reception of the random access response and a start of monitoring scheduling information from the first device, or a flag indicating whether the indicator is present in the random access response. The first device transmits the scheduling information to the second device based on the offset.
