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.

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: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.
Abstract translation: 描述用于执行数据服务请求延迟的用户设备（UE）设备的设备，系统和方法。 UE可以在小区重选期间检测数据服务请求失败，并且基于小区重新选择的状态推迟数据业务请求的重发。 该状态可以表示UE尝试驻留在小区上，或者UE正在监视与小区重选相关联的一个或多个度量。 为了推迟数据服务请求，UE可以延迟数据服务请求一段指定的时间，或者直到小区重选完成。 可以在协议栈的第一层上监视状态，并且数据服务请求可以由协议栈的第二层生成。 推迟可能是固定的或可变的时间段。

Abstract: Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Abstract: The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.

Abstract: Systems and methods performed by user equipment (UE) for communicating over a wireless communication network include receiving data representing one or more communication quality metrics for communication on a New Radio (NR) communication link of the wireless communication network. The method includes determining, based on the data representing the one or more communication quality metrics, a data throughput for the NR communication link of the wireless communication network. The method includes estimating a theoretical throughput for using a Long Term Evolution (LTE) communications link of the wireless network. The method includes comparing the data throughput using the NR communication link to the theoretical throughput for using the LTE communication link. The method includes causing a switch, based on the comparison, from the NR communication link to the LTE communication link.
