摘要： A method comprising transmitting a configuration of a default time period, wherein the default time period is for allowing a terminal device to consider a request for leaving an active network connection to a first network as accepted by the first network if the first network does not send a response within that the default period, to the terminal device, receiving a first message, from the terminal device, indicating a request to leave the active network connection, determining an overriding condition that overrides the default time period for leaving the active network condition and transmitting, to the terminal device, a second message comprising the overriding condition.

摘要： Systems, methods, apparatuses, and computer program products for data transmission with stateless routing are provided. Certain embodiments may include a radio resource control (RRC)-less or RRC-based mechanism for short data transmission (SDT) in an RRC inactive state, where the mechanism may be performed without storing or establishing a UE context in a distributed unit (DU), for a UE served by a single CU-user plane (UP). Certain embodiments may include a RRC-less mechanism for SDT in an RRC inactive state, where the authentication of the user equipment (UE) may be performed at the UP using UP integrity protection (IP) in a CU-UP. Certain embodiments may include a RRC-based mechanism for SDT in an RRC inactive state, where the authentication of the UE may be performed at the UP using UP IP in a CU-UP and/or at the CP using CP IP in a CU-CP.

摘要： There are provided measures for enabling/realizing an early evaluation for conditional reconfiguration in a mobile/wireless communication system. Such measures exemplarily include that a communication entity obtains an evaluation measurement configuration and an evaluation candidate cell set, performs an evaluation measurement in accordance with the evaluation measurement configuration on the evaluation candidate cell set, and performs or starts evaluating an execution condition for conditional reconfiguration for the evaluation candidate cell set on the basis of a result of the evaluation measurement, in the absence of and/or prior to availability of an actual configuration for conditional reconfiguration.

摘要： The present invention relates to survival time aware mobility and presents handover procedures when considering survival time (ST) requirements. It proposes a mechanism and embodiments to allow a target cell to have the information relating to a joining UE's Survival Time requirements as well as the ST status during the handover procedure. In particular, the invention is aimed at being introduced into the mobility procedures: Baseline Handover (BHO), Conditional HO (CHO), and Dual Active Protocol Stack (DAPS) HO. In addition to the aggregated RAN architecture, the mobility procedures can be applicable to disaggregated RAN architecture, e.g., CU-DU split.

摘要： A methods and apparatuses for communication are disclosed. The method comprises maintaining (600) a connected state with a first network with a first subscription identity used by the apparatus; maintaining (602) an inactive or idle state with a second network with a second subscription identity used by the apparatus, communicating (604) with the first network regarding the start, length and periodicity parameters of one or more communication gaps related to activities on the second network, receiving (606) from the first network one or more configurations of communication gaps and transmitting (608) to the first network information on a gap configuration or a change of one or more parameters in a gap configuration.

摘要： Where a UE moves between primary and/or secondary cells, the repeated reconfiguration of a UE at the network requires repeated signalling. Where non terrestrial networks nodes provide cells it may be possible to predict which cells a UE is likely to visit and when, based on the satellite movement. Embodiments make use of this ability to predict multiple future cells by transferring configuration information for a series of target cells in a single message, in some cases along with condition information indicating when the cell is likely to be providing radio coverage for that UE. Furthermore, to reduce signalling overhead some of the information is provided as a delta information, that is as an indication of how a previous configuration will change to provide the new configuration. A UE can apply the configuration information as the conditions become fulfilled.

摘要： Embodiments of the present disclosure propose a solution for availability of system broadcasted information such as GNSS information which can be used for deriving time and/or frequency domain compensation. According to embodiments of this present disclosure, a validity timer for system broadcasted information is introduced in both UE and network to guarantee the system broadcasted information availability status is synchronized in two nodes, and the system broadcasted information is valid to pre-compensate in time and/or frequency domain when the timer is running. In this way, the UE can be scheduled with correct timing and frequency estimation in UL transmission.
