Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.

Abstract: This disclosure relates to techniques for a wireless device to perform low latency communication using historical beam information. The wireless device may establish a radio resource control connection, and may subsequently release the resource control connection. The wireless device may store antenna element and beam information for the resource control connection. The wireless device may determine whether to use the stored antenna element and beam information when establishing another radio resource control connection. If the wireless device determines to do so, the wireless device may use the stored antenna element and beam information when establishing that radio resource control connection.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to determine whether or not a mobile alert message is in effect. Such a determination may be based on a cancellation message (or other message(s) received from the network, possibly in response to a query from the UE. Alternatively or additionally, such a determination may be based on monitoring rebroadcasts of the alert and/or determining that no rebroadcast has been received for a period of time.

Abstract: A device, system, and method select a frequency band during an attenuation activity state. The method is performed at a device that is configured to establish a network connection to a network having a first priority of available frequency bands set by the network. The method includes identifying an attenuation activity state. The method includes generating a second priority of the available frequency bands based on the attenuation activity state. The method includes selecting one of the available frequency bands based on the second priority to establish the network connection.

Abstract: Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for mitigating HTTP transaction errors for a data connection. The wireless device may establish a data connection over a first network interface of the wireless device at an HTTP layer of the wireless device. A transport connection may support the data connections and may support multiple HTTP transactions. An advisory signal may be received at the HTTP layer and, responsive to the advisory signal including first information, the HTTP layer may determine that at least a portion of the HTTP transactions can be (safely) retried. The HTTP layer may terminate, without notifying the application layer, the portion of HTTP transactions and may initiate, via a second transport connection established over a second network interface, retries of the first portion of HTTP transactions.
