Abstract: This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

Abstract: This disclosure relates to techniques for UEs (including link budget limited UEs) to improve communications performance with a cellular network. A UE may be configured to provide a request (for a first process executed by the UE) for a high-bandwidth connection to a base station of a cellular network during a first RRC connection. In some embodiments, the RRC connection is established by another process. In some embodiments, the UE is configured to receive signaling from the base station indicating that the base station cannot satisfy the high-bandwidth connection request and the UE is configured not to send or receive data for the high-bandwidth connection during the first RRC connection in response to the signaling. In some embodiments, the UE is configured to re-send the request on a second, subsequent RRC connection that is not established by the first process. In some embodiments, the UE is configured to opportunistically re-send the request on subsequent RRC connections established by one or more other processes until the base station is able to grant the request.

Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to more efficiently scan frequency bands for potential base stations may include a UE configured to store information regarding results of prior cellular scan operations for a cell and to perform a new cellular scan operation while camped in the first cell. The new cellular scan operation may be partially based on the stored information. The prior cellular scan operations may have been performed to identify frequencies of available cellular base stations. The UE may update the information regarding results of prior cellular scan operations with information regarding success or failure of the new cellular scan operation. The UE may maintain lists of cells for which a cellular scan has been successful or unsuccessful and adjust the new cellular scan operation based at least partially on contents of at least one of these lists.

Abstract: Throttling of transition attempts to connected mode based on user context. A wireless device may camp on a serving cell. A motion state of the wireless device may be monitored. One or more connected mode transition procedures on the serving cell may be attempted. If at least a threshold number of connected mode transition procedures fail on the serving cell while the wireless device is stationary, further connected mode transition attempts may be throttled for up to a certain amount of time. Alternatively, or in addition, the wireless device may bar itself from camping on that cell for up to a certain amount of time. Either or both of throttling connected mode transition attempts or barring cells may also be based on other aspects of user context, such as display state.

Abstract: This disclosure relates to techniques for dynamic selection of connection attempt throttling algorithms based on user context. According to some embodiments, a wireless device may monitor certain current conditions of the UE, such as battery level, user activity level, motion level, and/or other conditions. Depending at least in part on the current conditions of the UE, cellular connection attempt parameters may be selected. In some conditions the cellular connection attempt parameters may be selected such as to allow more aggressive pursuit of cellular connectivity, while in other conditions the cellular connection attempt parameters may be selected such as to allow less aggressive pursuit of cellular connectivity.
