Abstract: A method is provided that comprises providing a radio network service to at least one user equipment by a serving radio access node having context information in association with the at least one user equipment. The method comprises determining to shut down the radio network service. The context information is forwarded by the serving radio access node to a plurality of radio access nodes within reach, via a signaling procedure defined as a non-acknowledgement message procedure, for the plurality of radio access nodes to store the context information for enabling a continued radio network service to the at least one user equipment. And a mobility management function is informed of the determined shut down along with an indication of the plurality of radio access nodes for the mobility management function informing at least one candidate node for providing the continued radio network service of the plurality of radio access nodes.

Abstract: This disclosure presents processes for improving the quality of NR PDCCH reception at a UE when transmitted in a same orthogonal frequency-division multiplexing (OFDM) symbol and a same frequency domain resource element as an LTE CRS. Using a capability parameter of the UE, a network node can transmit an LTE CRS and NR PDCCH in the same OFDM symbol and the same frequency domain resource elements using various encoding schemes. The encoding schemes can be one or more of puncture signalling, superposition signalling, relative power levels, UE type, adjusting the AL of the LTE CRS, or various combinations thereof. The UE can decode the PDDCH using the encoding scheme. Legacy UEs can be supported with this disclosure by the network node selecting supported UE capabilities for the encoding. The network node can balance transmission reliability with available resources.

Abstract: Systems, methods, apparatuses, and computer program products for efficient registration for partially supported service areas are provided. One method may include providing, to at least one user equipment registered to a network within a registration area, information comprising one or more lists of single network slice selection assistance information (S-NSSAIs) and one or more lists of tracking area identities (TAIs). The one or more single network slice selection assistance information (S-NSSAIs) is included in a list of rejected single network slice selection assistance information (S-NSSAIs) or in a list of extended rejected single network slice selection assistance information (S-NSSAIs), and is associated with a cause value indicating that the one or more single network slice selection assistance information (S-NSSAIs) is not supported uniformly in the registration area and is not supported in a current tracking area.

Abstract: Embodiments of the present disclosure relate to a terminal device, a method and a medium for modifying or adapting a measurement configuration for a terminal device. In an aspect, a terminal device determines at least one of at least one scheduling restriction or at least one measurement configuration based on one or more conditions including an energy state of the terminal device. The terminal device transmits, to a network device, a request for modifying a configuration for performing measurements. The request comprises at least one of the at least one scheduling restriction or the at least one measurement configuration. With the embodiments in the present disclosure, the preferred measurement configuration and scheduling restrictions can be dynamically provided based on the priority and the energy state of the UE, and thus the energy consumption of energy harvesting devices can be reduced.

Abstract: Systems, methods, apparatuses, and computer program products for simultaneous registration to multiple networks are provided. A user equipment (UE) may perform dual registration to multiple networks, e.g., a 5G system (5GS) of equivalent public land mobile networks (PLMNs), equivalent stand-alone non-public networks (SNPNs), or a combination of PLMNs and SNPNs. When a UE is registered to the first network, the UE may select the second network for a second registration based on one or more criteria.
