    Abstract: Techniques and apparatus for achieving multi-cell synchronization for dual connectivity and carrier aggregation are described. In one technique, a timing difference between a first base station (BS) and a second BS is determined, where the first BS is in an asynchronous timing configuration with respect to the second BS. A measurement configuration for measuring signal(s) from the second BS is determined, based on the timing difference. The measurement configuration is signaled to a user equipment (UE) served by the first BS. The UE performs a measurement procedure for the signal(s) in accordance with the measurement configuration. In another technique, the second BS receives a synchronization request, which includes a first time stamp, from the first BS via a network interface between the first BS and the second BS. The second BS sends a synchronization response, which includes a second time stamp, to the first BS.

    Abstract: Certain aspects of the present disclosure provide techniques for uplink scheduling for communication on an uplink from a user equipment (UE) to a base station (BS). The uplink scheduling is based on uplink transmission (UL Tx) switching time and/or uplink data preparation time of the UE. The uplink data preparation time is calculated based on the UL Tx switching time. For example, a UE can report to a BS at least one of an indication of a UL Tx switching time and an uplink data preparation time of the UE. In return, the UE can receive an indication of uplink scheduling from the BS, which the UE can use to communicate with the BS.

    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may communicate with multiple beacon devices (e.g., road side beacons), where messages from the road side beacons may be transmitted over a sidelink communications link and may be used to determine a speed and/or location of the wireless device. In some examples, the messages may carry public safety information, location information, navigation information, or other types of information, which may be used, for example, to notify the wireless device of a nearby event, to enable navigation, or the like. When receiving messages from the road side beacons, the wireless device may report a status to a base station, which may determine a relationship between transmissions from the wireless device and predict future transmissions based on the relationship. As a result, the base station may modify communications parameters in accordance with the status of the wireless device.

    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

    Abstract: Methods, systems, and devices for wireless communications are described which provide for efficient backhaul communications and identification of resources for cross-link interference (CLI) measurements and reporting. A common resource pool may be configured in which CLI measurements for resources within the resource pool have a common configuration. When providing information indicating resources that are to be measured for CLI, a bitmap that indicates resources within the common resource pool may be provided with CLI measurement configurations corresponding to the common resource pool configuration. Such a bitmap may be communicated via backhaul connections between neighboring base stations when initiating a CLI measurement. Various described techniques also provide for common configuration for CLI measurements, provide for efficient reporting of CLI measurements, and provide for accurate representation of CLI based on measurements at a victim UE.

    Abstract: Aspects for enabling Multiple-Input-Multiple-Output (MIMO) communications using a plurality of transmitters across at least two supported frequency bands are disclosed. The apparatus may be a user equipment (UE) that includes, for each UE-supported frequency band, a plurality of transmitters capable when configured of coherently transmitting the received information over the frequency band with information to be transmitted to a base station. The apparatus can identify MIMO coherence capability information for the supported frequency bands on a per-band and a per-band combination basis. The apparatus may determine a proposed transmission configuration based on the MIMO capability information and may report, to the base station, the proposed transmission configuration.
