Abstract: Wireless communications systems and methods related to channel congestion estimations based on virtual collision metrics are provided. A user equipment (UE) may select a plurality of resources from a sidelink resource pool. The UE may request an evaluation of an availability of the plurality of resources and may receive an indication of the availability of the plurality of resources. The UE may further transmit, based on a virtual collision metric associated with the indication of the availability of the plurality of resources, a first sidelink transmission.

Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device. The packet delivery window configuration may indicate a periodicity, offset, start time, end time, and/or duration of the delivery windows, among other information. Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.

Abstract: Methods, systems, and devices for wireless communications are described that provide for timing synchronization among one or more time sensitive network (TSN) endpoints via a wireless communications network. A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.

Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.

Abstract: Techniques for clock synchronization over a wireless connection are provided. A first wireless node determines an offset between a first clock used by the first wireless node for a wired connection between the first wireless node and at least one upstream node and a second clock used by the first wireless node for a wireless connection between the first wireless node and a second wireless node on the downstream. The first wireless node transmits an indication of the determined offset to the second wireless node for use by the second wireless node to calibrate a third clock corresponding to the first clock to synchronize the third clock with the first clock, wherein the third clock is used by the second wireless node for a second wired connection with at least one downstream node.

Abstract: Techniques for mobility-aware contention procedures on a shared communication medium are disclosed. A connection failure associated with mobility between a source access point and a target access point sharing a communication medium may be detected. Based on the detected connection failure, a backoff threshold associated with contention-based access to the communication medium may be adapted. Contention for access to the communication medium may then proceed in accordance with the adapted backoff threshold.

Abstract: The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.
