Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform a method for supporting a periodical radio access network (RAN) notification area (RNA) mechanism when small data transmission (SDT) is enabled for a user equipment device (UE). The method may include the UE receiving, from a base station, an indication enabling an SDT procedure along with an indication of an RNA timer configuration, transitioning, to a radio resource control (RRC) inactive state, and initiating an RNA timer based on the RNA timer configuration. The UE may, upon initiation of the SDT procedure, stop the RNA timer and, upon termination of the SDT procedure, start the RNA timer. During the SDT procedure, the UE may receive any of an SDT termination indication, an SDT subsequent transmission indication, or an SDT subsequent transmission termination indication that may include an updated RNA timer configuration (and/or RNA timer reconfiguration).

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE transmits a connection request message to a base station over a first network using the first SIM, where the connection request message includes one or more capability indications of the UE. The UE receives a connection accept message from the base station, where the connection accept message includes one or more network capability indications corresponding to respective UE capability indications of the one or more UE capability indications. The UE performs communications with the base station according to the one or more network capability indications.

Abstract: An example method for wireless communication includes: transmitting by a base station, to a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); transmitting the CSI-RS and TRS based on the transmitted resource information to the user device, wherein the user device has exited the reduced power state; determining whether there is paging information to transmit in a first physical downlink shared channel (PDSCH) transmission for the user device; transmitting a downlink control information message, wherein the downlink control information message is based on the determination that there is paging information for the user device, and wherein the user device has synchronized with the base station; and transmitting the first PDSCH transmission, based on the determination that there is paging information for the user device.

Abstract: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

Abstract: Systems and methods for the use of measurement object having multiple synchronization signal block (SSB)-based measurement timing configurations (SMTCs) indicating a same periodicity and different offsets are disclosed herein. In some of these cases, a wireless communications network can provide a user equipment (UE) with a measurement object (MO) having up to a total number of total SMTCs. or having SMTC sets each of up to a predetermined number of SMTCs. UE determinations regarding a number of the SMTCs to use to perform one or more corresponding SSB measurements during a period of a periodicity indicated by one or more SMTCs of an MO are also discussed. The use of scheduling restrictions by the UE based on non-terrestrial network (NTN) characteristics of one or more of a serving cell and a neighbor cell to be measured are also discussed.

Abstract: This disclosure relates to techniques for handling timing alignment for configured grant based small data transmissions in inactive mode in a wireless communication system. A wireless device may establish a radio resource control connection with a cellular base station. The wireless device may receive an indication to release the radio resource control connection. The indication to release the radio resource control connection may configure resources for performing uplink transmissions while in the radio resource control inactive mode. A timing advance may be maintained while in the radio resource control inactive mode. An uplink transmission may be performed using resources configured for performing uplink transmissions while in the radio resource control inactive mode. The uplink transmission may be performed using the timing advance.
