Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may identify a burst periodicity for communication bursts over one or more cells, such as secondary cells (SCells) in accordance with a multi-carrier communication scheme. The UE and the base station may determine a cell dormancy pattern for switching the SCells between an active state and a dormant state based on the burst periodicity. The base station and the UE may use one or more bandwidth parts (BWPs) for communications and may configure the UE to perform BWP switching over the SCell during the dormancy state switching operation. The base station and the UE may communicate the bursts while the SCells are in the active state and may switch the SCells between the active state and the dormant state based on the cell dormancy pattern.

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: 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: Certain aspects of the present disclosure provide techniques for user equipment (UE)-centric clustering and efficient scheduling for coordinated multipoint (CoMP). A method for UE-centric clustering and central scheduling includes determining a UE conflict graph. Vertices in the UE conflict graph are UEs for which there is a transmission and edges between vertices are UEs that have a scheduling conflict. The method includes transmitting signaling to schedule the UEs with resources for the transmission based on the UE conflict graph. A method for UE-centric clustering and cluster scheduling includes determining a cluster graph. Vertices in the cluster graph are CoMP clusters for one or more UEs for which there is a transmission and edges between vertices are CoMP clusters that have a scheduling conflict. The method includes transmitting signaling to assign resources to the CoMP clusters based on the cluster graph.

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: 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: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for enhancing a device provisioning protocol (DPP) to support multiple configurators. In one aspect, a first configurator device can export a configurator key package. In one aspect, the configurator key package may be used for backup and restore of the configurator keys. The configurator key package may include a configurator private signing key and, optionally, a configurator public verification key. A second configurator device may obtain the configurator key package and also may obtain decryption information which can be used to decrypt the configurator key package. Thus, in another aspect, both the first configurator device and the second configurator device can use the same configurator keys with the device provisioning protocol to configure enrollees to a network.
