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: 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: Systems and methods for cross layer optimization for selection of a best or most preferred cell from conditional special cell (SpCell) change candidate cells are disclosed. The conditional SpCell change may be, for example, a conditional handover (CHO) or a conditional primary cell of a secondary cell group (PSCell) change (CPC). Conditions for a conditional SpCell change may be provided to a user equipment (UE). It may be that measurements on multiple cells meet the condition(s) for a conditional SpCell change by the UE. Preferences/criteria for selecting a cell from these multiple compliant candidate cells meeting the conditional SpCell change conditions are discussed herein. These criteria may include, but are not limited to, for example, a cell quality, an inter-versus intra-frequency handover, bandwidth, component carrier (CC) use, band, carrier type, needs/criticality of the application, congestion, frequency range, multiple subscriber identity module (MSIM) considerations, etc.

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: A wireless network may include a PCELL base station, an SCELL base station, and user equipment (UE) that communicate using standalone carrier aggregation. The UE may receive PCELL signals during first measurement periods, may perform first measurements on the PCELL signals, may receive SCELL signals during second measurement periods, and may perform second measurements on the SCELL signals. When a scheduled reporting time approaches, the UE may compare a duration between a most recent of the second measurement periods and the reporting time to a threshold. If the duration is less than the threshold, the UE may include the most recent second measurement in a measurement report transmitted at the scheduled reporting time. When the duration exceeds the threshold, the receiver may perform a third measurement on the SCELL signals during an unscheduled period prior to the reporting time and may include the third measurement in the measurement report.

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.
