Abstract: Apparatuses and methods for a wireless communication device having multiple Subscriber Identity Modules (SIMs) in which a first SIM is associated with an Internet Protocol (IP) Multimedia Subsystem (IMS) subscription used for IMS services. The method includes but not limited to, attaching the IMS subscription to a first cell of a packet-switched cellular network, determining a cause of IMS voice service being not currently available at the IMS subscription, determining availability of a wireless local area network (WLAN) connection at the IMS subscription, and providing voice service at the IMS subscription based on the cause of IMS voice service being not currently available and the availability of the WLAN connection at the IMS subscription.

Abstract: Embodiments described herein relate to systems and methods of managing communications for a wireless communication device having a first Subscriber Identity Module (SIM) associated with a first subscription and a second SIM associated with a second subscription. The method may include attempting a first activity by the first SIM with respect to a first network. The method may further include detecting a failure event of the first activity with respect to the first network. The method may further include identifying a time duration until performance of a reattempt of the first activity. The method may further include determining whether the identified time duration is greater than a threshold value. The method may further include, upon determining that the identified time duration is greater than the threshold value, performing a second activity by the second SIM with respect to a second network.

Abstract: An apparatus may communicate with at least two networks. The apparatus may be configured to opportunistically decode a channel from a first network and a channel from a second network in order to receive data from both networks. The apparatus may determine whether first data carried on a paging channel (PCH) is decodable from a subset of slots that carry the PCH. The subset of slots may be included in a set of slots that carry the PCH. When the PCH collides with a physical multicast channel (PMCH), the apparatus may decode second data carried on the PMCH instead of the first data when the first data is determined to be decodable from the subset of slots that carry the PCH, and decode the first data instead of the second data when the first data is not determined to be decodable from the subset of slots that carry the PCH.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may identify a completion of Internet Protocol multimedia subsystem (IMS) activity associated with an IMS only subscription of the wireless communication device. In some aspects, the wireless communication device may trigger a transfer from a connected mode to an idle mode based on identifying the completion of the IMS activity. Numerous other aspects are provided.

Abstract: The present disclosure presents a method and an apparatus for searching for service when a multi-mode UE goes out of service (OOS). For example, the disclosure presents a method for receiving a request to scan frequencies of a RPLMN of a first RAT and scanning the frequencies of the first RAT based on an acquisition database (ACQ DB). In addition, such an example method, may include sending an available PLMN list to the NAS layer, switching to a second RAT based on a request from the NAS layer, scanning frequencies of the second RAT based on the ACQ DB, and camping on a frequency of the second RAT found during the scanning of the frequencies of the second RAT based on the ACQ DB. As such, a method and an apparatus for searching for service when a multi-mode UE goes OOS may be achieved.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a user equipment (UE) with a first-active bandwidth part (BWP). The first-active BWP may correspond to a subset of a channel bandwidth. Retuning one or more components (e.g., radio frequency (RF) components) to the first-active BWP at the UE may involve a relatively significant delay. To avoid missing communications while tuning to the first-active BWP, the UE may initially tune to the channel bandwidth. The UE may identify a next-available time resource for retuning to the first-active BWP, where the next-available time resource may be a portion of an off-duration of a discontinuous reception (DRX) cycle or a portion of a measurement gap. The UE may use the time resource to retune to the first-active BWP while the UE is configured to reduce communications with a serving base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) may be configured with multiple bandwidth parts (BWPs) and may support multiple subscriber identification modules (SIMs) (e.g., may operate in a multi-SIM (MSIM) mode). The UE may tune away from a default data SIM (DDS) subscription for a tune away gap and may miss any downlink signaling, such as an indication of a BWP switch, for a duration of the tune away. To avoid latency resulting from such missed downlink signaling, the UE may support a mechanism according to which the UE may autonomously switch to a different BWP despite a missed command from a network entity. Such a mechanism may include transmission of a scheduling request (SR) on each of multiple BWPs configured for the UE and monitoring each of the multiple BWPs for signaling responsive to the SR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may switch the set of antennas that the UE uses to transmit sounding reference signal (SRS) transmissions. For example, the UE may switch from transmitting first SRSs that conflict with a scheduled communication from a first set of antennas to a second set of antennas (e.g., that is, the conflict may be at the first set of antennas). The UE may be transmitting second SRSs using the second set of antennas, and the switching may cause the UE to transmit the second SRSs using the first set of antennas instead. The second SRSs may not conflict with the scheduled communication (e.g., due to using different resources than the first SRSs), which may enable the UE to transmit the second SRSs and the scheduled communication using the same first set of antennas.

Abstract: Disclosed are methods and apparatuses for providing notifications in a communication network of a plurality of Internet of Things (IoT) devices. In an aspect, a supervisor device in the communication network detects a notification directed to a wireless mobile device in the communication network and sends at least one instruction to at least a first IoT device of the plurality of IoT devices to reduce an operating volume or suspend operation of the first IoT device. The first IoT device receives the at least one instruction from the supervisor device and reduces the operating volume of the IoT device or suspends the operation of the IoT device in response to the at least one instruction.

Abstract: Embodiments described herein relate to extending an awake period (on duration) or an inactivity timer duration in a Connected Discontinuous Reception (CDRX) mode for a first subscription based on activities of a second subscription. A method according to some embodiments includes determining that the awake period of the CDRX cycle associated with the first subscription collides with the activities of the second subscription, and extending the awake period by an extended awake period in response to determining that the awake period collides with the activities of the second subscription. In addition, a method according to some embodiments includes determining that the inactivity timer duration collides with the activities of the second subscription, and extending the inactivity timer duration for an extended inactivity timer duration in response to determining that the inactivity timer duration collides with the activities of the second subscription.
