Abstract: A user equipment (UE) 102 receives, from a radio access network (RAN) 105 and in a first cell 124, a resource for an uplink transmission to the RAN 105 when a radio connection between the UE 102 and the RAN 105 is suspended (e.g., event 1102); initiates, in a second cell 126 and the radio connection is suspended, a procedure to resume the radio connection with the RAN 105 (e.g., event 1106); and in response to the initiating, release the resource (e.g., event 1108).

Abstract: A method of managing configuration information for SDT operation is performed by a RAN node. The method includes transmitting to a UE, while the UE is in an RRC connected state, a first message, the first message including an SDT configuration for use by the UE when the UE operates in an RRC inactive state. The method also includes, after transmitting the first message, determining to release the SDT configuration. The method also includes, in response to the determining and while the UE is in the RRC inactive state, transmitting to the UE an RRC release message including a release indication for indicating that the UE is to release the SDT configuration.

Abstract: In a method of managing a configured grant small data transmission (CG-SDT) time alignment timer that indicates validity of a CG-SDT configuration, a user equipment (UE) receives a radio resource control (RRC) release message from a radio access network (RAN). In response to the RRC release message, the UE resets a medium access control (MAC) entity of the UE and, after resetting the MAC entity, starts the CG-SDT time alignment timer.

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: A base station can implement a method for configuring a multicast radio bearer (MRB) for a multicast and/or broadcast services (MBS) session. The method may include determining (1502) that the MBS session or the MRB requires uplink resources. The method may also include, based on the determining, selecting (1504) a configuration for the MRB, the configuration including configuration parameters for a user equipment (UE) to receive the MBS session. The method may further include transmitting (1506) the selected configuration to the UE.

Abstract: A user equipment (UE) performs a method of obtaining system information. The method includes disabling (328) a system information request function of the UE while the UE is in an inactive state and, while the system information request function is disabled and the UE is in the inactive state, communicating (316) with a radio access network (RAN) using small data transmission (SDT). The method also includes enabling (330) the system information request function of the UE when the UE is no longer communicating with the RAN using SDT.

Abstract: A user device (UE) for managing radio bearers communicates, with a first base station over a first radio bearer associated with a dedicated control channel and configured to carry at least application-layer measurement reporting information, the radio bearer associated with a logical channel identity (2502); receives, from a radio access network (RAN) including the first base station and a second base station, a message related to (i) the first radio bearer or (ii) a second radio bearer having the logical channel identity and terminated at the second base station (2504); and release or reconfigure the first radio bearer in response to the message (2506).

Abstract: Managing paging for Multicast and/or Broadcast Services (MBSs) of interested UEs that do not have an active radio connection with the RAN can include providing, in MBS service paging instructions, indications of respective radio capabilities of interested UEs in conjunction with the identifications of the interested UEs, e.g., so that DUs can have necessary UE radio capability information in-line with the paging instructions. Another technique can include a base station providing an indication of UE radio capability information of interested UEs to another base station. Still another technique includes storing, at a DU or at a CU, an indication of UE radio capabilities and/or a default or predetermined set of UE radio capabilities for use in paging interested UEs.

Abstract: In a method for configuring a radio bearer, a distributed unit (DU) of a distributed base station receives, from a central unit (CU) of the distributed base station, a request to configure radio resources for a radio bearer and, based on one or more factors associated with the radio bearer, either includes or refrains from including in a response one or more configuration parameters for the radio bearer. The DU also transmits the response to the CU.

Abstract: A user device (UE) capable of operating in dual-mode connectivity (DC) with a master node (MN) and a secondary node (SN) detects a low-power condition of a battery of the UE. In response, the user device prevents the UE from operating in DC with the SN, so that the UE and the MN are configured to operate in single connectivity.
