Abstract: To manage a power coordination configuration when performing a dual active protocol stack (DAPS) procedure, a UE receives (702A), from a radio access network (RAN), a power coordination configuration for application by the UE to constrain uplink power when communicating with a source cell and a target cell of the RAN, initiates (704A) the DAPS procedure in accordance with the power coordination configuration, and in response to detecting a trigger condition, releases (706A) the power coordination configuration.

Abstract: To configure a connection with a UE, a central unit (CU) of a distributed base station provides, by processing hardware to the UE, a conditional configuration for a cell of a distributed unit (DU) of the base station (1002). The CU receiving, by the processing hardware, an identifier of the cell of the DU (1004). Additionally, the CU determines, by the processing hardware, that the UE connects to the cell based on the identifier of the cell (1006), and communicates with the UE in accordance with the conditional configuration for the cell (1008).

Abstract: A technique for managing mobility configuration in a UE includes obtaining conditional configuration information including (i) a conditional configuration related to a candidate cell in the RAN, and (ii) a condition to be satisfied before the UE applies the configuration (1202). The technique further includes detecting that a non-conditional procedure related to the UE and the RAN has been initiated, when the UE is connected to the RAN via at least one cell (1204); determining, subsequently to the detecting and when the non-conditional procedure has not been completed, that the condition is satisfied (1206); and completing, by the processing hardware, (i) the conditional procedure in accordance with the conditional configuration and (ii) the non-conditional procedure (1208).

Abstract: A method in a first base station for managing a conditional operation related to a user equipment UE includes sending, by processing hardware to the UE, a conditional connection information including at least one of a (i) configuration data related to a second base station in order for the UE to operate in dual connectivity with the first base station and the second base station, or (ii) one or more conditions connecting to the second base station (2202). The method also includes, in response to determining, by the processing hardware, that the UE is to suspend a radio connection with the first base station (2204): causing the UE to suspend a radio connection with the first base station (2206), and causing the second base station to release the conditional connection information (2208).

Abstract: A security key management method can be implemented a user equipment (UE) capable of concurrent communication with a master node (MN) and a secondary node (SN). The method includes transitioning (504) from a connected state in which the UE communicates with the MN using a first security key and with the SN using a second security key (502), to an inactive state in which a radio connection between the UE and a radio access network (RAN) is suspended. The method further includes performing a procedure for transitioning from the inactive state to the connected state, including generating a new RAN key KSN corresponding to the SN (506) and generating a new security key for communicating with the SN based on at least the new RAN key KSN (508).

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: A UE that is connected to a wireless communication system via a first base station utilizing a first RAT enters into an inactive state of a first protocol corresponding to the first RAT. The UE (re)selects a second base station utilizing a second RAT for resuming its connection with the system, transitions into an inactive state of a second protocol corresponding to the second RAT, and requests the second base station to resume the UE's system connection. The second base station obtains UE context information from the first base station, and transmits associated context/configuration information to the UE. Based on the received context/configuration information, the UE configures, enters into a connected state of the second protocol, and begins transmitting/receiving data to/from the system via the second base station. The second base station informs the first base station of the UE's resumed connection with the system via the second base station.

Abstract: One or more processors, operating in a source base station and/or a target base station, determines a change in the termination point from the source base station to the target base station for a radio bearer with a current count value according to data unit sequencing. The one or more processors determine (1806) whether a user equipment (UE) changes the data unit sequencing as a result of the change in the termination point. In a first instance, the one or more processors cause the target base station to apply (1810) the current count value to the radio bearer, in response to determining that the data unit sequencing does not change. In a second instance, the one or more processors cause the target base station to apply (1820) a new count value different from the current count value to the radio bearer, in response to determining that the data unit sequencing changes.

Abstract: To efficiently support location services, abase station receives an uplink (UL) message from a user equipment (UE) (2002). The base station determines whether the UL message includes a positioning protocol message associated with a positioning protocol for exchanging information related to a location service (2004). In a first instance, in response to determining that the UL message includes the positioning protocol message, the base station sends the positioning protocol message to a local entity that implements a location service (2010). In a second instance, in response to determining that the message does not include any positioning protocol messages, the base station sends at least some of the data included in the UL message to a remote node (2012).
