Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a plurality of beams, from a base station, wherein the plurality of beams are associated with a corresponding plurality of monitoring occasions for a first subscription of the UE. The UE may determine whether a monitoring occasion for a second subscription of the UE collides with one or more of the plurality of monitoring occasions, for the first subscription of the UE, corresponding with the plurality of beams. The UE may transmit, to the base station, an indication of a selected beam, from the plurality of beams, based at least in part on the measuring and the determining. Numerous other aspects are provided.

Certain aspects of the present disclosure provide techniques for channel quality indicator (CQI)-based downlink buffer management as well as mitigating throughput loss in dual connectivity with multi-SIM. A method that may be performed by a user equipment (UE) includes communicating with a first network on a first channel using a first technology, determining whether a tune-away associated with the first technology will occur, and outputting, for transmission to the first network on a second channel using a second technology, a channel quality indicator (CQI) report corresponding to the second channel if the tune-away will occur, wherein the CQI report indicates a lower CQI for the second channel than a current CQI for the second channel.

CQI-based downlink buffer management

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that it is a multi-subscriber identity module (SIM) device that supports communications with at least a first subscription corresponding to a first SIM and a second subscription corresponding to a second SIM, where the communications are transmitted or received via a single transceiver of the UE. Accordingly, the UE may simultaneously perform packet-based voice traffic using the first subscription and data communications using the second subscription, where the data communications occur during one or more durations of time in which the packet-based voice traffic is absent. For example, the UE may transmit or receive messages using the first subscription and then transmit or receive messages using the second subscription by tuning the single transceiver away from the communications for the first subscription when the packet-based voice traffic is absent.

In an embodiment, a user equipment (UE) determines an emergency health condition for a user that is defined based on a set of health-related parameters crossing a corresponding set of thresholds. The UE receives health data from a set of health monitoring sensors that are each configured to monitor one or more health-related parameters of the user. The UE detects, while a restricted mode restricting access to a set of communicative functions of the UE is active, that the emergency health condition for the user exists based on the received health data indicating that the set of health-related parameters have crossed the corresponding set of thresholds. The UE disables the restricted mode in response to the detecting. The UE conveys, using one or more communicative functions from the set of communicative functions that are made available by the disabling of the restricted mode, an alarm related to the detected emergency health condition for the user.

Power control performance for user equipment

Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.

Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.
