Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of signalling enabling Timing Advance (TA) exchange between User Equipment (UE) and Radio Access Network (RAN). The method comprises receiving, at a first device, a TA margin from a second device; transmitting, to the second device, information associated with a reference location of the first device at a first time point; determining a reference TA of the first device at least based on the reference location of the first device; determining an actual TA of the first device at least based on an actual location of the first device at a second time point; and determining, based on a comparison of a TA margin with a difference between the reference TA and the actual TA, whether to transmit an updated reference location of the first device to the second device. In this way, the control for uplink overhead from TA/location updates and probability of impacting downlink scheduling become flexible. Furthermore, the downlink delay can be optimised and meanwhile overhead in case of very few small packets transmitted can be minimized. As a result, the network can optimize its own performance and the battery savings of the users.

Abstract: Disclosed are methods for selecting a random access procedure type. An example method may include receiving configuration information including a threshold associated with a transmission quality factor via a non-terrestrial network downlink, obtaining a value of the transmission quality factor, and selecting a 2-step random access procedure or a 4-step random access procedure based on the threshold and the obtained value of the transmission quality factor. Related apparatuses and computer readable media are also disclosed.

Abstract: A base station serving UE(s) receives validity time information for cell(s) formed by other base station(s). The validity time information indicates at least a time period when corresponding cells are available for use by the UE(s). The base station determines action(s) to perform for the UE(s) based on the validity time information. A UE receives, from a base station, validity time for cell(s) formed by other base station(s). The UE performs action(s) based on the validity time of the cell(s).

The method further comprises transmitting, by the network node, a pre-configured measurement gap pattern, in response to the reported first level capability indicates that the user equipment needs a measurement gap. The method further comprises receiving, by the network node, status of the pre-configured measurement gap pattern is changed by the user equipment.

Abstract: The present disclosure relates to selecting a NTN device. In particular, a NTN device transmits information related to a set of NTN devices to a terminal device. The terminal device selects a NTN device from the set of NTN devices based on the information. The terminal device transmits data to the selected NTN device. In this way, it can avoid long latency.

Abstract: Example embodiments of the present disclosure relate to a terminal device, a network device, methods, apparatuses, and a computer readable storage medium for HARQ state for RRC configuration for multi-TB scheduling. In the solution, a terminal device may receive information which schedules multiple TBs and indicating multiple HARQ processes, the terminal device may further determine a same HARQ state for all of the multiple HARQ processes based on a configured HARQ state of a specific HARQ process in the multiple HARQ processes. As such, a same HARQ state may be applied for all scheduled TBs. Therefore, a flexibility on scheduling is provided, in addition, the DRX behavior for multi-TB scheduling is simplified.

Abstract: A plurality of DRBs may be configured for UDC. The DRBs configured for UDC may only be activated for UDC operation upon UE request. The UE may cause selected DRBs to be activated for UDC operation using an uplink RRC message, a user plane control PDU, or a PDCP/SDAP header in a data PDU. A base station may transmit, to a UE, a UDC configuration configuring one or more DRBs to support UDC for the UE without initial UDC operation activation; receive, from the UE, an indication to activate at least one DRB with UDC configured for UDC operation; and, in response to the indication, at least one of: perform, locally, a PDCP entity re-establishment procedure associated with the at least one DRB, or inform the UE to perform a PDCP entity re-establishment procedure associated with the at least one DRB.

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.
