Abstract: This document describes methods and systems for common search space configuration and system information acquisition. As part of the methods and systems, a base station wirelessly communicating with a user equipment that is in an engaged mode determines to configure a common search space through which the user equipment can receive a system information block that is other than a system information block type 1 or a master information block. The base station transmits a first message that includes a set of common search space configuration parameters for the user equipment to receive the other system information block. The base station transmits, in accordance with the set of common search space configuration parameters, a second message that includes the other system information block.

Abstract: To manage configuration when a UE operates in multi-radio dual connectivity (MR-DC), the 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 (1102). The UE receives, by the processing hardware and from the RAN, an indication that the UE is to release the MR-DC (1104), and determines, by the processing hardware and prior to the UE transitioning from the MR-DC to a new connectivity mode, whether the UE is to release the conditional configuration (1106).

Abstract: A user equipment (UE) receives, from a radio access network (RAN), conditional configuration information including (i) a configuration related to a base station or a cell, and (ii) a condition to be satisfied before the UE applies the configuration (2102). The UE determines a procedure to which the conditional information pertains (2104). The UE applies, during the determined procedure, the configuration if the condition is satisfied (2106).

Abstract: A user device capable of receiving a full configuration related to a radio connection to a base station and a delta configuration which the user device can apply to a first configuration received previously (i) receives, from the base station while the user device is operating in a cell covered by the base station using the first configuration, the full configuration providing information for user device operation within a candidate cell (1404), (ii) determines whether a set of one or more conditions associated with the full configuration to the candidate cell is satisfied (1406), and (iii) connects to the candidate cell using the full configuration if the user device determines that the set of conditions is satisfied (1410).

Abstract: A source base station receives, from a candidate base station while a user device is operating in a source cell of the source base station, a first message that indicates a conditional handover configuration providing information for user device operation within a candidate target cell of the candidate base station, but does not indicate a corresponding condition for handing over to the candidate target cell. The source base station generates the corresponding condition for handing over to the candidate target cell, and sends, to the user device, a second message that indicates the conditional handover configuration and the corresponding condition.

Abstract: A base station security communicates with a UE operating as an SN in dual connectivity of the UE with a first MN and the SN. The base station communicates with the UE over a radio interface using a first security key (802). The base station then receives, from a second MN, a first message including data for obtaining a second security key for communicating with the UE (804) and suspends application of the second security key to downlink traffic to the UE until a second message is received (806). In response to receiving the second message, base station communicates with the UE over the radio interface using the second security key (808).

Abstract: A method, in a user device configured to communicate with a base station, for managing communication of a segmented radio resource control (RRC) message that includes N segments includes transmitting (222) a first M segments of the segmented RRC message to the base station, M being an integer greater than zero and less than N, detecting (230 or 330), by processing hardware of the user device and before transmitting an (M+1)-th segment of the segmented RRC message, an intervening event, that triggers an RRC procedure, and, after detecting the intervening event, transmitting (260) the (M+1)-th segment through an N-th segment of the segmented RRC message to the base station before the RRC procedure has completed.

Abstract: This document describes methods and systems for user equipment (UE) context transfer over radio access network (RAN) paging. A first base station receives from a second base station a first message that includes a context that is associated with a user equipment while the user equipment was in an engaged mode with the second base station. The first base station transmits a second message that is a paging message to the user equipment and in response receives, from the user equipment, a third message that includes a resume message authentication code identifier. After the first base station verifies the third message using the resume message authentication code identifier, the first base station transmits, to the user equipment, a fourth message that enables the user equipment to resume the engaged mode with the first base station in accordance with the context.

Abstract: A UE communicating in DC with an MN and an SN receives a configuration related to a C-SN and at least one condition for connecting to the C-SN, determines that a radio connection between the UE and the MN has failed, and transmits a first indication of the failed radio connection to the SN to initiate a recovery procedure. The UE also releases the configuration and/or the at least one condition, or suspending a procedure, for connecting to the C-SN\.

Abstract: This document describes methods and devices for preventing inadvertent idle mode for a UE in multi-node connectivity with a master node and at least one secondary node. In an implementation, the UE includes first and second Media Access Control (MAC) entities for respectively communicating with a master node and a secondary node. The UE starts or restarts at least one data inactivity timer responsive to detecting a communication of data on at least one of the MAC entities. Rather than inadvertently releasing resources of a node as part of the UE transitioning to an idle mode, thereby potentially ceasing connectivity of active communication with the node, the methods and devices described here prevent this release unless connections to both nodes are inactive. By so doing, degradation to a user's experience and the waste of power, computing, or bandwidth resources may be prevented.
