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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select information indicating a request or a notification that is independent of a request for an uplink grant. The UE may transmit the information in a message associated with a scheduling request. Numerous other aspects are described.

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, apparatuses, and computer-readable medium are provided for rate matching. An example method may include receiving a rate matching pattern configuration indicating at least a first control resource set (CORESET) in a first bandwidth part (BWP) and a second CORESET in a second BWP. The example method may also include receiving a physical downlink shared channel (PDSCH) in the first BWP. The example method may include processing the PDSCH transmission based on the rate matching pattern configuration, where the processing may include rate matching around resources of the first CORESET and first associated search space (SS) sets and the second CORESET and second associated SS sets.

Abstract: Apparatus, methods, and computer-readable media for facilitating power savings while monitoring for paging messages and wakeup signals are disclosed herein. An example method for wireless communication at a UE includes receiving an indication of an active BWP associated with an ON duration of a DRX cycle. The example method also includes monitoring a first bandwidth for a WUS at a WUS occasion of the DRX cycle, the first bandwidth corresponding to a subset of the active BWP. The example method also includes transitioning to an awake state for the ON duration when the WUS is received at the WUS occasion.

Abstract: Certain aspects of the present disclosure provide techniques for merging pages in communications systems using carrier aggregation (CA) or secondary component carriers (SCCs). An example method that may be performed by a user equipment (UE) includes: operating in a connected mode using a default data subscription (DDS) associated with a primary cell (PCell); detecting one or more secondary cells (SCells) associated with the DDS are configured for operating in the connected mode; and decoding one or more paging messages using at least a secondary component carrier (SCC) associated with a first SCell of the one or more SCells.

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: A dual subscriber identity module (SIM) dual standby (DSDS) device may determine that the DSDS device is to communicate in a first communication session of the DSDS device instead of a second communication session of the DSDS device when the first communication session of the DSDS device and the second communication session of the DSDS device are contemporaneously active. The DSDS device may generate a session initiation protocol (SIP) message to pause the second communication session with another device based on the determination that the DSDS device is to communicate in the first communication session instead of the second communication session associated with the DSDS device. The DSDS device may transmit the generated SIP message to the other device associated with second communication session to pause the second communication session associated with the other device.

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: A multi-subscriber identification module (SIM) wireless communication device with a first SIM and a second SIM associated with a shared radio frequency (RF) resource may determine that timing collisions are predicted between an active period of a discontinuous reception (DRX) cycle associated with the first SIM and an active period of a DRX cycle associated with the second SIM. In response, the wireless communication device may determine whether the first SIM is registered with an IP Multimedia Subsystem (IMS) to use Voice-over-wireless local area network (VoWLAN) service over a wireless local area network (WLAN). If the first SIM is registered with the IMS to use VoWLAN service over the WLAN, the wireless communication device may shift the conflicting DRX cycle associated with the first SIM by a time margin, and receive paging messages for mobile terminating calls on the modem stack associated with the first SIM over the WLAN.

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.
