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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network controller of a wireless communication system may receive a time-sensitive network (TSN) traffic configuration that indicates a duration of a gate open state for a TSN traffic flow and a periodicity with which the gate open state occurs; configure one or more quality of service (QoS) parameters, associated with the wireless communication system, for a QoS flow that is to carry the TSN traffic flow, wherein the one or more QoS parameters are configured based at least in part on one or more TSN capability parameters associated with the network controller and at least one of the duration of the gate open state or the periodicity; and transmit the one or more QoS parameters to a base station of the wireless communication system. Numerous other aspects are provided.

Abstract: A wireless communication system is provided allowing a base station to indicate RTT compensation for UEs to adjust their local time clocks to correct propagation delay timing errors and synchronize with the global clock of a base station. A base station sends a downlink transmission including timing information to a UE and receives an uplink transmission from the UE after the downlink transmission. The base station determines a RTT compensation associated with the timing information based on a RTT between the downlink transmission and the uplink transmission. The base station then transmits the RTT compensation to the UE. UEs are thus allowed to synchronize at a high precision with the time clock of the base station. UEs may be configured with different resolutions or granularities in timing correction so that certain UEs can achieve high precision timing correction while other UEs can adjust their time clocks with less precision.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and high availability within the Time-Sensitive Networking (TSN) framework. For example, the UE may be integrated as a sensor in a motion control system or similar applications. The UE and base stations are synchronized with the TSN clock, and are configured to perform positioning measurements at a specific time point within the TSN framework. The time point, for example, may be a global sampling point, at which all sensor nodes in the TSN framework perform position measurements. 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, such as a motion controller in a motion control system.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first set of parameters based at least in part on a first reference signal received from a first transmit receive point (TRP) and a second set of parameters based at least in part on a second reference signal received from a second TRP; determine a common parameter using the first set of parameters and the second set of parameters; and perform a tracking loop operation using the common parameter or the first set of parameters and the second set of parameters, wherein the tracking loop operation comprises at least one of a frequency tracking loop operation or a time tracking loop operation. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain a timing synchronization signal from a base station over a cellular wireless communication link. The UE may configure, based at least in part on the timing synchronization signal, a timer function of the UE as a precision time protocol (PTP) server. The UE may configure a PTP announce message based on the timer function and, in some examples, one or more metrics of the cellular wireless communication link. The UE may transmit the PTP announce message over a local communication network.

Abstract: Apparatus and methods of wireless communications include, at a receiving node, receiving timing information corresponding to a traffic class identifier. The timing information being associated with a time interval for communicating data of a traffic class corresponding to the traffic class identifier. Aspects include receiving traffic data pertaining to the traffic class, determining that the traffic data was transmitted or is received outside the time interval, and then buffering the traffic data. Additionally, aspects include forwarding the traffic data in response to a next occurrence of the time interval. A transmitting node may be configured with complimentary functions.

Abstract: Wireless communication in a heterogeneous network may be facilitated by establishing connections with femto nodes based on page notifications from macro nodes to user equipment (UE). A UE in idle mode may monitor paging resources provided by a macro node, discover presence of a femto node based on signals received from the femto node, and establish a communicative connection with the femto node based on a page notification received from the macro node over the paging resources.

Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.
