Described herein are solutions for reducing packet loss for low latency, low loss, scalable throughput (LAS) traffic. A user equipment (UE) can determine whether a base station is capable of supporting LAS traffic and can implement rate adaptation in different ways based on the LAS capabilities of the base station and active queue management (AQM) policies of the base station. A base station can establish protocol data unit (PUD) sessions between the UE and different instances of a network slice based on whether the base station receives packets from applications capable of LS4 rate adaptation. These and many other features and examples are described in additional detail.

Systems, methods, and devices for packet drop prevention with L4S

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.

Systems, methods, and devices for optimizing radio access technology and resource selection

Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

Smart data mode for 5G wireless devices

An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for dynamic transmit power adjustment, the processing circuitry is to decode baseband configuration information received from a base station. The baseband configuration information including at least a modulation and coding scheme (MCS), resource block (RB) allocation, and carrier assignment for uplink (UL) transmission and downlink (DL) reception. A communication mode is selected based on the baseband configuration information. An additional maximum power reduction (A-MPR) is determined based on the baseband configuration information and the selected communication mode. UL data is encoded for transmission to the base station via the selected communication mode and using transmit power adjusted based on the determined A-MPR. New signaling enhancements between the UE and the network (on a Uu interface) and between two UEs (on a PC5 sidelink interface) are also disclosed.

Dynamic transmit power adjustment

This disclosure relates to techniques for providing a framework for supporting custom signaling between a wireless device and a cellular network. A wireless device and a cellular base station may establish a wireless link. The wireless device and the cellular base station may perform custom signaling in accordance with the custom signaling framework.

Framework for supporting custom signaling between a wireless device and a cellular network

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.

Identifying new radio coverage availability in non-standalone mode

Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.
