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 extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to a Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.

Abstract: Systems and processes are for measuring link metrics for a plurality of reference signals associated with a plurality of beams from a base station. The systems and methods are for determining that a link metric value is less than or equal to a predetermined threshold. The systems and process include detecting beam failure, classifying beam recovery as high priority, opportunistic beam failure recovery and performing an optimal random access channel (RACH) process through intelligent selection of beams and modules.

Abstract: A wireless communication device (UE) may conduct wireless communications using one or more antennas according to multiple radio access technologies (RAT) associated with corresponding operating frequency bands. The UE may perform adaptive antenna tuning, for example, application-based antenna tuning for increasing the operating efficiency of the UE, which may improve user experience. The UE may periodically identify one or more applications running on the UE, the respective RATs that support the (running) applications, and which of the corresponding frequency bands are used by the (running) applications. The UE may determine the tuner device settings for tuning the one or more antenna(s) based on the (running) applications or the type and/or priority of the (running) applications, which RATs support the running applications, which of the corresponding frequency bands are used by the (running) applications, and operating conditions associated with the frequency bands used by the (running) applications.
