Abstract: A wireless network may include a device that communicates with base stations. The device may include a set of antennas. The network may transmit a message identifying a subset of frequency resources of a frequency band for the device. The subset can include a bandwidth part configuration, a component carrier configuration, and/or a physical resource block configuration. The device may generate wireless performance metric data with the set of antennas using the subset of frequency resources rather than averaging wireless performance metric data across the entire band. The device may identify a best performing antenna based on the performance metric data and may use that antenna to transmit signals. The best performing antenna may be different than when averaged across the entire frequency band, serving to optimize wireless performance particularly when the frequency band has a wide bandwidth.

Abstract: This disclosure relates to techniques for performing wireless communications using a split bearer. A user equipment device may perform a recovery operation for a lost uplink packet. The recovery operation may be in response to an indication from the network or may be initiated autonomously by the device.

Abstract: This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.

Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: An electronic device includes a transceiver and processing circuitry that is operatively coupled to the transceiver. The processing circuitry is configured to transmit, via the transceiver and to a second electronic device, a request for a wireless communication session with the second electronic device. The processing circuitry is also configured to communicate, via the transceiver, one or more first wireless signals during the wireless communication session with the second electronic device. Additionally, the processing circuitry is configured, after communicating the one or more first wireless signals, to extend the wireless communication session by transmitting, via the transceiver and to the second electronic device, one or more second wireless signals based on no wireless signals being communicated via the wireless communication session for a duration of time.

Abstract: Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.

Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.
