    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a digital simulation to determine a precoding matrix indicator (PMI) associated with a digital reception beam. A base station may send, to the UE, a reference signal. The UE may perform a coarse beam search on the reference signal using non-oversampled digital reception beams. The UE may measure the signal strength of the reference signal for each of the non-oversampled digital reception beams and select the non-oversampled digital reception beam with the strongest signal. The UE may perform a refined beam search procedure on the selected beam by using a set of oversampled digital reception beams which correspond to the selected non-oversampled digital reception beam. The UE may determine the PMI associated with the strongest oversampled digital reception beam and send the PMI in a report to the base station.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may utilize synchronization signal block (SSB) and channel state information reference signal (CSI-RS) based beam management to select beams for communicating with a base station. For example, a UE may receive, from a base station, control signaling that configures the UE to monitor a set of SSBs and a set of reference signals. The UE may select a subset of the set of SSBs based on measuring a first signal metric for each SSB of the set of SSBs. In some examples, the UE may select a reference signal subset of the set of reference signals that correspond to the subset of the set SSBs, and may communicate a data transmission with the base station using a first beam selected based on measuring a second signal metric for each reference signal in the reference signal subset.

    Abstract: Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.

    Abstract: Certain aspects of the present disclosure provide techniques for reducing inter-vehicle interference. In certain aspects, a method performed by a first vehicle may include detecting a second vehicle is in proximity of the first vehicle, determining that the second vehicle includes an intra-vehicle, obtaining resource allocation information associated with the intra-vehicle network of the second vehicle, the resource allocation information indicating a first set of resources allocated to one or more first sensors of the second vehicle located at least in a first portion of the second vehicle, determining that the first set of resources conflict with a second set of resources allocated to one or more first sensors of the first vehicle located in at least a first portion of the first vehicle, and performing one or more actions to resolve the determined conflict between the first set of resources and the second set of resources.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for channel-bandwidth-attributed per-band user equipment capability reporting. A user equipment (UE) may determine a first and second set of physical layer capabilities associated with a first and second channel bandwidth, respectively. The UE may transmit a first and second UE capability report to the base station, where the capability reports may indicate the corresponding channel bandwidth and may include the UE physical layer capabilities. The UE may receive control information indicating a channel bandwidth from the base station and the UE may communicate with the base station according to the received control information.

    Abstract: In some wireless systems (e.g., 5G new radio (NR) systems), a user equipment (UE) may experience coexistence interference when using collocated radio transceivers to simultaneously communicate using different radio access technologies (RATs). To mitigate the coexistence interference, the UE may transmit a configuration request to a base station, where the configuration request may identify that the UE is operating on multiple RATs, identify that the UE is experiencing coexistence interference, or request specific reference signal settings or resources. The base station may modify reference signal transmissions and settings based on the configuration request. For example, the base station may transmit more frequent channel state information reference signals (CSIRS) to the UE, and the UE may report channel state information (CSI) more frequently in response. In other cases, the base station may modify a demodulation reference signal (DMRS) pattern, CSIRS resources, or CSI reporting settings based on the configuration request.

    Abstract: The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network with Hammerstein structure by dividing an aggressor signal into real and imaginary components, augmenting the components by weight factors, executing a linear combination of the augmented components, and executing a nonlinear sigmoid function for the combined components at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce real and imaginary components of an estimated jammer signal. A linear filter function may be executed for the components of the jammer signal, and to produce a nonlinear interference estimate used to cancel the nonlinear interference of a victim signal.
