Abstract: Methods, systems, and devices for wireless communications are described. An access node may schedule traffic with different levels of priority for communications with a user equipment. The access node may receive a time-sensitive networking time-aware schedule from a first interface via an Ethernet frame that defines a set of periodic time intervals reserved for transmitting traffic with a high-priority (e.g., hard-real time traffic). In some cases, one or more frequency resources may additionally be reserved for the high-priority traffic. Accordingly, during the reserved time intervals, if the high-priority traffic is present, the access node may transmit the high-priority traffic on the reserved frequency resource(s). Outside the reserved time intervals, the access node may schedule lower-priority traffic on the reserved frequency resource(s) in addition to the other resources. Alternatively, high-priority traffic may interrupt previously scheduled lower-priority traffic during the reserved time intervals if high-priority traffic is present.

Abstract: Methods, systems, and devices for wireless communications are described that provide time synchronization via wireless communications for devices that use strict timing synchronization. A user equipment (UE) may obtain time synchronization via a wireless connection between the UE and a timing source that may be associated with a base station (or another wireless device). In some cases, the timing source may be synchronized at the UE by determining, using periodic synchronization resources, a propagation delay between the UE and the base station that is based on a timing of a line-of-sight instance of a transmission between the base station and the UE. The propagation delay may be used to determine a timing advance value for use in timing synchronization. One or more devices may be coupled with the UE and the UE may provide commands to the one or more devices that are synchronized according to the synchronized timing source.

Abstract: Methods, systems, and devices for wireless communications are described. A first node (e.g., a user equipment (UE)) may receive a timing synchronization signal from a second node (e.g., a base station) over a cellular wireless communication link. In some aspects, the timing synchronization signal may indicate mapping information to synchronize the first node with the second node. The mapping information may be for synchronizing a first time of a first clock of the first node to a second time of a second clock of a second node. The first node may synchronize the first time of the first clock to the second time of the second clock based at least in part on the mapping information and the synchronization information. The first node may transmit a timing control based on a timing of the second clock to a device connected to the first node via a local wired interface.

Abstract: Some wireless communication systems may attempt to balance frequent transmission opportunities (e.g., where the frequency of the opportunities may refer to gaps in the time domain, frequency domain, etc.) with a desire for communication reliability and/or interference diversity. In accordance with the described techniques, some such systems may apportion communicating devices into groups, where resources are strategically assigned to each group so as to reduce latency without significantly compromising communication reliability or interference diversity (e.g., by allowing a membership of the groups to cycle through all possible combinations before repeating). Such techniques may support delay-sensitive communications, channel sounding procedures, or other similar types of transmissions. Resources may be allocated based on a scheduling parameter transmitted to a user equipment (UE), which may implicitly or explicitly indicate a plurality of resource offsets to the UE.

Abstract: A server initiating shut down of a transport control protocol (TCP) connection when a radio connection is terminated is problematic because a new radio connection must be established for the sole purpose of shutting down the TCP connection. Hence, network and terminal resources for establishing the radio connection are wasted. Accordingly, a method, an apparatus, and a computer program product for initiating a closing of a transport layer connection at a client are provided. The apparatus determines whether a functionality associated with the transport layer connection satisfies at least one criterion, and closes the transport layer connection when the functionality satisfies the at least one criterion while a radio layer connection is available. As a result, the TCP connection is shut down by the client before the server can activate a new radio connection for the sole purpose of terminating the TCP connection.

Abstract: Methods, systems, and apparatuses are described for managing interfaces for wireless communications. In one method, at least one active interface of a user equipment (UE) may be used for the wireless communications. While using the at least one active interface, a need for increased bandwidth for the wireless communications may be detected. Based at least in part upon detecting the need for increased bandwidth, at least one additional interface of the UE may be activated for use in the wireless communications. More than one of the active interfaces of the UE may be simultaneously used for the wireless communications, and may be used independent of network coordination of the active interfaces.

Abstract: Methods, systems, and devices for wireless communications are described. A system may support techniques for triggering user equipment (UE) assistance information (UAI) based on mobility, wake up signal (WUS) configuration, or both. In some cases, a UE may communicate with a network node (e.g., a base station) on a first channel according to a discontinuous reception (DRX) configuration. The UE may determine that a speed of the UE satisfies a mobility threshold and may transmit UAI requesting one or more updated DRX configuration parameters based on the speed of the UE satisfying the mobility threshold. Additionally or alternatively, the UE may receive signaling configuring the UE to monitor for WUSs and may transmit UAI requesting one or more updated DRX configuration parameters based on the WUS configuration. The UE may receive control signaling configuring the DRX configuration with the one or more requested parameters in response to the UAI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.
