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: 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. 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a grant indicating a modulation and coding scheme (MCS) that indicates that the grant is for a retransmission of an initial communication. The UE may decode, based at least in part on the grant indicating the MCS that indicates that the grant is for the retransmission and using a transport block size (TBS) of a prior communication, a communication scheduled by the grant, wherein the prior communication is prior to the initial communication. Numerous other aspects are described.

Abstract: A method of wireless communication performed by a user equipment (UE) includes receiving one or more configuration messages indicating configuration of the UE with a first component carrier (CC) and at least a second CC for a first subscription corresponding to a first subscriber identity module (SIM) of the UE. The method further includes performing one or more operations associated with a second subscription corresponding to a second SIM of the UE during a time interval. During the time interval, communication by the first subscription using the second CC is avoided based on a first throughput associated with the first CC exceeding a second throughput associated with the second CC.

Abstract: Various embodiments provide methods implemented by a processor executing on a mobile communication device (e.g., a multi-SIM-multi-active communication device) to opportunistically schedule a victim subscription's power monitoring activities to occur during periods in which the aggressor subscription is already scheduled not to transmit, thereby reducing the amount of time the aggressor subscription must perform Tx blanking to accommodate the victim subscription's idle-standby-mode operations. Specifically, the victim subscription's monitoring activities may be scheduled to occur while the aggressor subscription is operating in a compressed mode. As a result, the overall throughput/performance of an aggressor subscription is improved as the aggressor experiences relatively fewer blanked transmissions without affecting the victim subscription's ability to perform power-monitoring operations.

Abstract translation: 各种实施例提供了通过在移动通信设备（例如，多SIM多活动通信设备）上执行的处理器实现的方法来机会地调度受害者订阅的电力监视活动，以在攻击者订阅已经被调度的时段期间发生 从而减少攻击者订阅必须执行Tx消隐的时间，以适应受害者订阅的空闲待机模式操作。 具体来说，受害者订阅的监视活动可能被安排在攻击者订阅以压缩模式运行时发生。 因此，攻击者订阅的总体吞吐量/性能得到改善，因为侵略者经历相对较少的空白传输，而不影响受害者订阅执行电源监控操作的能力。
