Abstract: A source donor, for managing a connection between a user equipment (UE) and a radio access network (RAN) via an integrated access backhaul (IAB)-node, (i) determines (2002), when the IAB-node communicates with the RAN via the source donor, that the IAB-node is to migrate from the source donor to establish a new radio connection with the RAN, and (ii) subsequently to the determining and prior to the UE and the IAB-node establishing respective new connections with the RAN, facilitates (2004) exchange of data between the UE and a core network (CN) via the source donor and the target donor.

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 base station for configuring bandwidth parts (BWPs) in a certain cell, for access by UEs, configures (1502) an initial BWP within a bandwidth of a cell, configures (1504) a multicast and broadcast services (MBS) BWP within the bandwidth of the cell, wherein the MBS BWP is dedicated to conveying MBS information, and transmits (1506), in the cell, an indication of the initial BWP and the MBS BWP, to provide a UE with access to the initial BWP and the MBS BWP.

Abstract: To manage a preferred configuration indicative of a maximum allocation preferred by the UE for at least one resource, a UE transmits (802A) the preferred configuration to a RAN, transitions (804A) to a state in which a radio connection between the UE and the RAN is suspended, and releases (806A) the preferred configuration, prior to communicating data over the radio connection.

Abstract: A radio access network (RAN) for enabling execution of a dual active protocol stack (DAPS) procedure at a UE determines that the UE is to release at least one cell via which the UE communicates with the RAN, prior to executing the DAPS procedure (2402), causes the UE to release the at least one cell (2404), and transmits a command to the UE to execute the DAPS procedure (2406).

Abstract: A radio access network (RAN) for configuring a user equipment (UE) transmits, to the UE, (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 conditional configuration during a conditional procedure (1802), determines subsequently to the transmitting, that the UE is to perform an immediate procedure related to the RAN (1804), and provides, to the UE, an indication that the UE is to release the conditional configuration (1806).

Abstract: To support devices with different bandwidth capabilities, a base station configures a first initial bandwidth part (BWP) of a first width within a bandwidth of the first cell (1002) and configures a second initial BWP of a second width, within the bandwidth of the first cell (1004). The base station transmits an indication of the first BWP in the first cell and an indication of the second BWP in the first cell or a second cell, to cause a first user equipment UE having a first bandwidth capability to access the first BWP, and a second UE having a second bandwidth capability to access the second BWP (1006).

Abstract: This document describes methods and devices for a handover of a user equipment from source base station (a Fifth Generation (5G) New Radio (NR) base station) to a target base station (another 5G NR base station or an Evolved Packet Core (EPC) network base station). The source base station, which is in communication with the user equipment, determines to handover the user equipment to the target base station. The source base station, then determines whether to use a delta configuration or a full configuration for handing over the user equipment. For the full configuration, the source base station either excludes the delta configuration from, or indicates use of the full configuration in, handover preparation information. By so doing, the source base station enables handover of the user equipment to the target 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 obtain control channel information from a base station that communicates with the user device via a shared carrier, a user device monitors (1502) a control channel on the shared carrier according to a pre-transmission pattern of control channel occasions. While monitoring the control channel using the pre-transmission pattern, the user device receives (1504) from the base station, via the shared carrier, a signal indicating a transmission time during which the shared carrier is available to the base station. In response to receiving the signal, the base station monitors (1506), during the transmission time, the control channel on the shared carrier according to a transmission pattern of control channel occasions that is different than the pre-transmission pattern but includes at least one control channel occasion that overlaps a control channel occasion of the pre-transmission pattern.
