Abstract: A base station can implement a method for managing transmission of multicast and/or broadcast services (MBS) using semi-persistent scheduling (SPS). The method includes: transmitting (1702), to a user equipment (UE), a configuration for receiving MBS data on SPS radio resources; providing (1704), to the UE, an indication to activate receiving the MBS data in accordance with the configuration; and transmitting (1706), to the UE, the MBS data in accordance with the configuration.

Abstract: A user equipment (UE) in communication with a radio access network (RAN) in accordance with a first configuration (i) receives (1102) from the RAN, a conditional configuration for application in a conditional procedure when a corresponding condition is satisfied; (ii) subsequently to receiving the conditional configuration, applies (1104) a second configuration received from the RAN; (iii) detects (1106), after applying the second configuration, a failure to execute the conditional procedure; and (iv) in response to the detecting, continues (1108) to apply the second configuration or notifies the RAN of the UE reverting back to the first configuration.

Abstract: A network node, operating as a secondary node (SN) for a user equipment (UE) communicating in dual connectivity (DC) with a master node (MN) and the SN, can implement a method for managing deactivation and activation of a secondary cell group (SCG). The method includes detecting (2302) a first indication that an activation status of the SCG is to change, and changing (2304) the activation status at the SN in response to the detecting. Further, the method includes reactivating or releasing (2306) the SCG in response to detecting a second indication related to the SCG.

Abstract: A user equipment (UE), for managing information related to sidelink communications, when the UE has a radio connection with a radio access network (RAN), (i) transmits (1802), to the RAN, sidelink information for generating, at the RAN, a sidelink configuration for the UE, (ii) determines (1804), subsequently to the transmitting, that the radio connection with the RAN is to be modified, and (iii) processes (1806) the sidelink information in response to the determination. A RAN, for managing information related to sidelink communications, when a UE has a radio connection with the RAN, (i) receives (1902), from the UE, sidelink information, (ii) generates (1904), using the sidelink information, a sidelink configuration for the UE, (iii) determines (1906) that the radio connection with the UE is to be modified, and processes (1908) the sidelink information in response to the determination.

Abstract: A method in a base station for managing communication of multicast and/or broadcast services (MBS) includes causing (1402) establishment of a session for transmitting MBS data packets from a core network (CN) to a user equipment (UE). The method also includes transmitting (1404) configuration parameters associated with the session to the UE. Further, the method includes transmitting (1406) MBS data packets to the UE in accordance with the configuration parameters.

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: This document describes techniques and devices for efficient handling of a resource control state change and multi-node connectivity. Instead of performing multiple radio resource control (RRC) procedures to change a resource control state of a user equipment (UE) and establish, modify, or release a connection with multi-node connectivity, the techniques described herein combine the multiple RRC procedures into a single RRC procedure that supports both a resource control state change and multi-node connectivity. In particular, a master node sends a resource control state and multi-node connectivity message that includes both state change information and multi-node connectivity information. With this single message, timing and power resources of the UE can be conserved and failures resulting from asynchronous communication of the state change information and the multi-node connectivity information can be avoided.

Abstract: This document describes methods, devices, systems, and means for the transfer of radio bearer (RB) configurations from a Fifth Generation (5G) New Radio (NR) base station (121) to an Evolved Universal Terrestrial Radio Access (E-UTRA) base station (122). The 5G NR base station (121) configures an RB configuration to configure an RB for communication of Protocol Data Units between the 5G NR base station (121) and a user equipment (111). The 5G NR base station (121) determines to hand over the user equipment (111) to an Evolved Universal Terrestrial Radio Access (E-UTRA) base station and sends a Handover Request message for the user equipment (111) to the E-UTRA base station (122). The 5G NR base station (121) receives a Handover Request Acknowledge message from the E-UTRA base station (122) and transmits a 5G NR Radio Resource Control (RRC) message including an E-UTRA RRC message to the user equipment (111).

Abstract: To communicate data in an inactive state associated with a protocol for controlling radio resources, a UE determines, when the UE is in the inactive state, that data is available for transmission to a RAN (1602). The UE applies a security function to the data to generate a secured packet (1604) and transmits the secured packet to the RAN while the UE is in the inactive state (1606). In response to determining that the RAN has not received the secured packet, performing at least one of (i) re-transmitting the secured packet in an uplink message associated with a second random access procedure, or (ii) transmitting, to the RAN, a request to resume or set up a radio connection.
