Abstract: An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.

Abstract: Methods related to an inactive state of a user equipment (UE). In one example, when an amount of data in an uplink buffer is less than a threshold, the data is sent to the network while remaining in the inactive state. In another example, when reselecting to a different cell, the UE attempts to reselect to the different cell and remain in the inactive state. When transitioning to a connected state at the reselected cell, the UE sends a resume request including an identification of the first cell. In another example, when a high priority or a background PLMN search is performed in the inactive state, the results are cached and implemented the earlier of when a timer expires or the UE enters an idle state. In another example, a cell reselection criteria is altered in the inactive state to make it less likely that a cell reselection will occur.

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: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: A user equipment (UE) is configured to connect to a primary cell serving a primary component carrier (PCC) in the licensed spectrum and a secondary cell serving a secondary component carrier (SCC) in an unlicensed spectrum. The UE is configured with a Connected Discontinuous Reception (C-DRX) functionality including an onDuration. The UE determines a first duration based on an amount of time between when a first operation related to an exchange of data over the SCC is to be performed and when the exchange of data over the SCC is likely to occur, determines whether the exchange of data over the SCC is likely to occur during the onDuration based on the first duration and when the exchange of data is unlikely to occur during the onDuration, delays when the first operation is to be performed to cause the exchange of data over the SCC to occur during the onDuration.

Abstract: This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.
