Abstract: A method for communication includes obtaining a timing signal from a timing synchronization reference source, computing a system frame number (SFN)—direct frame number (DFN) offset, creating a timing fingerprint using the timing signal and the SFN-DFN offset, the timing fingerprint also comprising additional timing information, entering the timing fingerprint into a database, continually updating the timing fingerprint, determining whether the timing signal remains within a threshold, if the timing signal exceeds the threshold, iterating the timing fingerprint, verifying the timing fingerprint to determine whether there is a timing inconsistency between a most recent timing fingerprint and current time, if the timing fingerprint is verified, using the SFN-DFN offset to derive current DFN timing to decode a sidelink control information (SCI) communication, and if the SCI communication is decoded, using the timing signal for communicating over a sidelink communication channel.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may prevent rejected attachment requests when connecting to a trusted wireless local area network (WLAN) and from a wireless wide area network (WWAN). For example, an attachment packet data network (PDN) connection may be maintained with the WWAN while connected to the trusted WLAN. In some cases, the connection used to maintain the attachment may be an internet protocol (IP) multimedia subsystem (IMS) connection. Alternatively, the UE may determine that the WLAN connection is a trusted connection and deactivate the WWAN connection. Should the WLAN become unavailable the UE may reactivate the connection with the WWAN.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine that a number of access stratum (AS) operations or communications have failed while attempting to communicate with a cell. Based on the AS failures, the UE may deprioritize the cell. For example, based on the deprioritization, the UE may bar certain cells from selection or reselection procedures. The UE may thus attempt to select or reselect a different cell even if the cell is ranked lower based on a selection criteria or reselection criteria. In some cases, UEs may store and share historical AS failure information that may also be used to determine when to deprioritize a cell. In some cases, a group of cells may be deprioritized (e.g., a group based on frequency, network, or tracking area).

Abstract: The disclosure generally relates to network-initiated and client-initiated mechanisms to enable quality of service (QoS) for web-based client applications that may high efficiency, high performance, or otherwise guaranteed service levels. For example, to enable QoS for calls or other sessions associated a web-based application, one or more signaling messages may be exchanged between a server and a first user equipment (UE) to establish a call between the first UE and a second UE and to establish a peer connection between the server and at least the first UE. As such, QoS may be activated for at least the peer connection between the first UE and the server, wherein the server may route data associated with the web-based application between the first UE and the second UE over the established peer connection to implement the activated QoS.

Abstract: Methods, systems, and devices for improved acquisition of wireless communication systems or networks are described. A wireless communication device may be connected to a first network that uses a first radio access technology (RAT). When a failure occurs (e.g., lost connection), the device may attempt to acquire a cell or channel of another network that uses a second RAT. The time consumed for acquiring the channel of the second RAT may be reduced by providing a suitably prioritized list of channels. In some examples, the device may identify a channel for initial access or following a call failure based on prior successful access on that channel, or based on information provided by a server, or both.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a user equipment (UE) to predict a gain state for an initial acquisition procedure. For example, the UE may use a machine learning (ML) model to predict an initial gain state which is likely to result in a successful initial acquisition procedure (e.g., without adjusting the gain state and reattempting the initial acquisition procedure). The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.
