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: A cellular communications system may include a user equipment (UE) that executes a target and non-target applications. The UE may convey a first stream of non-quality-of-service (QoS) wireless data with a first external device over a first Transmission Control Protocol (TCP) session and may receive a second stream of non-QoS wireless data from a second external device over a second TCP session. Responsive to a drop in data rate of the first stream, the UE may perform mitigation operations that adjust receipt of the second stream to boost the data rate of the first stream. The mitigation operations may include transmission of a triple duplicate acknowledgement (TDA), delayed transmission of an acknowledgment (ACK) to the second stream, and/or terminating the second TCP session. This may prevent disruptions to user experience with the first software application even when the network has downlink data to transmit to the UE.
