Abstract: A secondary node (SN) for requesting a master node (MN) to page a user equipment (UE) operating in dual connectivity (DC) with the MN and the SN receives, from a core network (CN), downlink traffic for the UE in an inactive state of a protocol for controlling radio resources, the inactive state being associated with a suspended radio connection between the UE and a radio access network (RAN) (802), and transmits, to the MN, a message that causes the MN to initiate RAN paging of the UE (804).

Abstract: To resume a connection with a base station, a user equipment (UE) communicates messages with the base station in accordance with a format that corresponds to a first radio access technology (RAT), using a radio connection over a radio interface that conforms to a second RAT (702). The UE suspends the radio connection (704) and, subsequently to the suspending, transmits to the base station an indication that the radio connection has been resumed, in accordance with the format that corresponds to the first RAT (708).

Abstract: A method, in a user device configured to communicate with a first base station via a radio link, for managing communication of a segmented radio resource control (RRC) message that includes N segments includes transmitting (212) a first M segments of the segmented RRC message to the first base station, M being an integer greater than zero and less than N, detecting (220), by processing hardware of the user device and before transmitting an (M+1)-th segment of the segmented RRC message, a failure of the radio link, and, after detecting the failure of the radio link, transmitting (264) at least a last N−M+1 segments of the segmented RRC message to either the first base station or a second base station.

Abstract: Techniques and apparatuses are described for managing inter-radio access technology capabilities of a user equipment. A base station (gNB base station 121) receives a New Radio capability information element (information element 500) that indicates one or more core networks supported by the user equipment (UE 110). Based on the New Radio capability information element, the base station generates a measurement configuration and sends measurement configuration to the user equipment (at 1010). Afterwards, the base station receives one or more measurement results based on the measurement configuration (at 1030). The base station then determines a handover type for the user equipment (at 1105, at 1205, at 1305), and initiates the handover based on the determined handover type (at 1110, at 1210, at 1310).

Abstract: This document describes methods and devices for a handover of a user equipment (110) from source base station (a Fifth Generation (5G) New Radio (NR) base station (121)) to a target base station (another 5G NR base station (123) or an Evolved Packet Core (EPC) network base station (122)). The source base station (121), which is in communication with the user equipment (110), determines to handover the user equipment (110) to the target base station (123,122). The source base station (121), then determines whether to use a delta configuration or a full configuration for handing over the user equipment (110). For the full configuration, the source base station (121) either excludes the delta configuration from, or indicates use of the full configuration in, handover preparation information. By so doing, the source base station (121) enables handover of the user equipment (110) to the target base station (123,122).

Abstract: A method of managing synchronization with a UE can be implemented by a DU of a distributed base station. The method includes transmitting, to the UE of the distributed base station, a CG-SDT configuration for use by the UE when the UE is in an inactive state. The method also includes, after transmitting the CG-SDT configuration to the UE, starting or restarting a time alignment timer that indicates validity of the CG-SDT configuration and, while the time alignment timer is running, receiving or attempting to receive transmissions from the CE in accordance with the CG-SDT configuration.

Abstract: To manage configuration, a UE receives, by processing hardware and from a radio access network (RAN), conditional configuration information including (i) a conditional configuration related to a base station operating in the RAN, and (ii) a condition to be satisfied before the UE applies the configuration (702). The UE receives, by the processing hardware and from the RAN, a message including an indication that the UE is to add, modify, or release a radio bearer (RB) (704), and determines, by the processing hardware, to ignore the conditional configuration in response to receiving the message (706).

Abstract: Allocating resources to user devices in a base station includes transmitting, to a user device, indications of a first time-frequency resource including a first frequency sub-band within a bandwidth part allocated in an unlicensed spectrum and a second time-frequency resource including a second frequency sub-band within the bandwidth part, performing a channel access procedure on the first channel corresponding to the first frequency sub-band, and a second channel corresponding to the second frequency sub-band, to obtain channel occupancy time on at least one of the first channel or the second channel; and transmitting, within the obtained channel occupancy time on at least one of the first channel or the second channel, downlink control information to a user device over a first time-frequency resource that includes the first frequency sub-band or a second time-frequency resource that includes the second frequency sub-band.

Abstract: A master node (MN) can implement a method for managing a conditional procedure that involves a user equipment (UE), a candidate secondary node (C-SN), and the MN. The method may include transmitting, to the C-SN, a request to perform the conditional procedure related to the C-SN and the UE, the conditional procedure associated with a condition and a conditional configuration according to which the UE connects to the C-SN when the condition is satisfied; receiving, from the C-SN, a response to the request, the response including an SN-to-MN container; and retrieving the conditional configuration from the SN-to-MN container.

Abstract: Base stations perform methods for supporting a conditional procedure for a user equipment (UE). A method performed by a first base station may include receiving (1202), by the first base station from a second base station, an indication of one or more candidate secondary cells to which the UE can connect, subject to a condition, to communicate in dual connectivity (DC); receiving (1204), by the first base station, subsequently to the UE connecting to a secondary cell among the one or more candidate secondary cells for which the condition is satisfied, coordination information for the secondary cell, the coordinating information being usable for coordinating usage of radio resources with the second base station while the UE communicates in DC; and applying (1206), by the first base station, the coordination information to coordinate the usage of radio resources with the second base station.
