Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. Further, the apparatus may be configured to determine that content is available for reception based on broadcast context information. In an aspect, the apparatus may be in an idle or inactive mode and may be associated with a first base station that is associated with a first radio access technology (RAT) that does not support broadcasting of the content. The apparatus may be further configured to receive a release message from the first base station, the release message including redirection information indicating a second base station associated with a second RAT that supports broadcasting of the content, establish a connection with the second base station based on the redirection information, and receive the content from the second base station using the second RAT.

Abstract: A new radio (NR) user equipment (UE) registration procedure that may be executed by a UE and a network is disclosed, resulting in a UE registration that may be more efficient than existing UE registration procedures. For example, the UE registration procedure may utilize messaging between an extensible authentication protocol (EAP) component and a non-access stratum (NAS) component to abort the registration procedure when a non-recoverable EAP failure occurs, or suspend or re-start a NAS registration timer when a recoverable EAP failure occurs.

Abstract: Various aspects of the disclosure relate to handover of a user equipment (UE) between a standalone mode of operation and a non-standalone mode of operation. For example, a UE may be handed-over from standalone to non-standalone, or vice versa. Moreover, this handover may be an inter-system handover (e.g., between an LTE core network and an NR core network).

Abstract: In one instance, a user equipment (UE) determines, at an application layer, an application activity that triggers a service request before data arrives at a buffer of the UE. In response to the determining, the UE may send, from a NAS layer (non-access stratum layer), the service request to a base station requesting one or more radio bearers for one or more service contexts when no radio bearer is assigned for the one or more service contexts. Alternatively, the UE may send a schedule request from a lower layer than the NAS layer when the radio bearer is already assigned before data arrives at the buffer of the UE.

Abstract: In one instance, a base station configures a first set of UEs, served by a serving base station, with a first IRAT measurement reporting threshold (inter-radio access technology measurement reporting threshold). The base station also configures a second set of UEs, served at the serving base station, with a second IRAT measurement reporting threshold that differs from the first IRAT measurement reporting threshold when a number of UEs served by the serving base station exceeds a congestion threshold.

Abstract: A method at a user equipment (UE) includes measuring a signal quality of each cell detected from a plurality of frequencies included in a connection release message from a radio access technology (RAT) . The measuring may occur during a long-period SIB collection for a previously determined target cell. The method also includes determining a new target cell in place of a previously determined target cell based at least in part on a signal quality of each cell measured during the long-period SIB collection for the previously determined target cell.

Abstract: In a method and system for wireless communication, a user equipment (UE) determines a signal quality of a serving cell of the first RAT and a signal quality of neighbor cells of the first RAT are all below a first threshold. The UE selects a first target cell of the second RAT for a synchronization channel decoding procedure when the signal qualities are all below the first threshold. The UE prevents switching the synchronization channel decoding procedure from the first target cell of the second RAT to a second target cell of the second RAT, during a measurement procedure and after an inter-radio access technology (IRAT) measurement of the measurement procedure. The UE prevents the switching when a difference between a signal quality of the first target cell and a signal quality of the second target cell is below a second threshold.

Abstract: A method of wireless communication includes determining when a tune away from a serving RAT to a non-serving RAT occurs. The method also includes determining whether to suspend one or more periodic uplink transmission before the tune away based on a serving cell signal quality, a specified quality of service, and/or timing of an uplink transmission in relation to the tune away.

Abstract: A method of wireless communication at a user equipment (UE) includes initiating a procedure for a circuit switched fall back (CSFB) service in response to a mobile originated voice call or a mobile terminated voice call in a radio access technology (RAT) not supporting circuit switched voice calls. The method further includes determining whether a time to trigger (TTT) timer has expired for a measurement report configured to trigger a handover to a target cell. The method also includes determining whether the target cell is of a RAT supporting circuit-switched voice calls. If so, sending of the measurement report is delayed, i.e., when the RAT of the target cell does not support circuit-switched voice calls.

Abstract: A user equipment (UE) improves measurement procedures during a communication cycle, such as a connected mode discontinuous reception cycle (C-DRX cycle). In one instance, the UE enters a C-DRX off duration during a C-DRX cycle of an ongoing communication. The UE then stops background activity until a start of a C-DRX on duration of a next C-DRX cycle when a signal quality of a serving radio access technology (RAT) is below a predefined threshold.
