Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a master information block (MIB) that includes an indication that there is no cell-defining synchronization signal block (SSB) on a frequency on which the UE is camped; and deprioritize a reselection procedure for one or more cells on the frequency based at least in part on the indication that there is no cell-defining SSB on the frequency. Numerous other aspects are provided.

Abstract: Methods, systems, and apparatuses for wireless communication are described. A user equipment (UE) may receive information from a network node. The system information may include inter-frequency configuration and measurement reporting configuration. The UE may perform a measurement of a frequency or multiple frequencies that are associated with the inter-frequency configuration. Subsequent to the measurement, the UE may transmit a report of the measurement of the frequency or multiple frequencies to the network node during a radio resource control (RRC) connection procedure based on the measurement reporting configuration.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.

Abstract: In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode.

Abstract: Methods implemented on mobile devices and stored on non-transitory process-readable storage media enable selectively blocking tune-ways to functionalities of a Dual-subscription, Dual-standby (DSDS) mobile device to avoid impairing high-priority calls. An embodiment method implemented in a call manager executing on a processor of the DSDS mobile device may include determining whether a tune-away is blocked based on whether a high-priority call (e.g., VoLTE call) is active on a first functionality, and blocking the tune-away to a second functionality in response to determining that the high-priority call is active on the first functionality. The method may further include allowing the tune-away to the second functionality in response to determining that the high-priority call is not active on the first functionality. In some embodiments, the first functionality may be a packet-switching subscription (e.g., a LTE subscription) and the second functionality may be a circuit-switching subscription (e.g., a GSM subscription).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may establish a communication connection with a serving cell associated with a first discontinuous reception (DRX) cycle configuration, determine, based at least in part on at least one of a first on duration of a first DRX cycle indicated by the first DRX cycle configuration or a type of traffic of one or more communications received during the first DRX cycle, an autonomous measurement gap associated with a neighboring cell, and perform a measurement of the neighboring cell during the autonomous measurement gap. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, while operating in an out-of-service (OOS) mode associated with a first network, that a second network satisfies one or more switching criteria. The UE may increase a time duration associated with a periodic network acquisition scan associated with the first network based at least in part on detecting that the second network satisfies the one or more switching criteria. The UE may switch, while operating in the OOS mode, from using the first network for connectivity to using the second network for connectivity based at least in part on detecting that the second network satisfies the one or more switching criteria. Numerous other aspects are described.

Abstract: Various aspects include methods for supporting handover of a Voice over Internet Protocol (IP) (VoIP) call, such as a Voice over Wi-Fi (VoWi-Fi) call, with a user equipment (UE). Various aspects may enable VoWi-Fi call handover from support via an evolved Packet Data Gateway (ePDG) to support via Long Term Evolution (LTE) when Voice over New Radio (NR) (VoNR) is not supported by a User Equipment (UE) computing device and/or a fifth generation (5G) standalone (SA) (5G SA) network in which the UE is located.
