Abstract: In an aspect, an apparatus, e.g., a base station of a first network, maybe configured to receive UE capability information from each UE of a plurality of UEs, the UE capability information indicating a number of different carrier synchronization timings that the UE can track within a plurality of carriers. The carriers maybe associated with multiple different networks including the first network. The apparatus maybe configured to determine, based on the received UE capability information, a set of synchronization-timing priorities indicating a priority for timing synchronization types for use within each carrier of a set of carriers of the plurality of carriers, and broadcast the set to the UEs. In an aspect, a UE may determine and send the UE capability to a base station. The UE may receive the set of synchronization-timing priorities and perform timing synchronization based on the received set of synchronization-timing priorities.

Abstract: An apparatus, such as a user equipment or a vehicle, may receive a signal associated with vehicle-to-everything (V2X) communication. The apparatus may determine a total energy that corresponds to the received signal, such as by measuring the energy on one or more resources. The apparatus may determine a fractional energy associated with a first technology of the total energy, such as by detecting a sequence associated with a first technology included in the received signal and determining the energy with which the detected sequence is received. The apparatus may determine presence of a second technology based on the determined fractional energy.

Abstract: An effective way for the cellular device-to-device communication and the short range communication to share a set of channels for communication is desired. The apparatus may be a user equipment (UE). The apparatus determines a priority level of each channel of a plurality of channels. The apparatus determines whether a first channel of the plurality of channels, the first channel having a highest priority level, is occupied by short range wireless communication. If the first channel is occupied by the short range wireless communication, the apparatus determines availability of one or more remaining channels of the plurality of channels for a cellular device-to-device (D2D) communication, where the one or more remaining channels are different from the first channel.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus receives a D2D resource message based on a change in an uplink-downlink subframe configuration of at least one frame. The D2D resource message enables the apparatus to determine D2D resources allocated for D2D transmissions after the change in the uplink-downlink subframe configuration. The apparatus determines a subset of the D2D resources to be used for performing D2D transmissions based on the received D2D resource message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include a radar which is used for object detection, such as a vehicle UE detecting other vehicle UEs in a vehicle-to-everything (V2X) communications system. The UE may be configured for coordinated interference, where radars transmit a common waveform while applying different delays to prevent negative co-channel interference effects, such as false or ghost targets. The techniques described herein support configuring a common configuration for network-assisted coordinated interference by considering capabilities of UEs and radars within a geographic area controlled by a network entity. The network entity may identify and indicate a waveform configuration which is used by radars within the geographic control area of the network entity.

Abstract: Certain aspects of the present disclosure provide techniques for coordinating waveform parameters and frame delays for multi-radar coexistence. An example method performed by an apparatus comprising a radar device includes transmitting, based on a transmission configuration, one or more first signals of a plurality of signals in an environment via the radar device in a first frame of a plurality of frames according to a first delay value occurring after a frame prior to the first frame and transmitting one or more second signals via the radar device in at least a second frame of the plurality of frames according to a second delay value occurring after the first frame based on the transmission configuration. In some cases, the transmission configuration comprises a common transmission configuration for use in the environment. Additionally, in some cases, the second delay value is different from the first delay value.
