Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a vehicle may identify a set of zones of the vehicle, each zone including a number of components connected to a wireless in-vehicle network of the vehicle. A scheduler of the vehicle may associate a different set of frequency resources to each zone of the vehicle and may allocate frequency resources to each component of the vehicle from the set of frequency resources associated with the zone in which the component is located. The scheduler may associate the different sets of frequency resources with the different zones of the vehicle such that two zones that are located at opposite sides or ends of the vehicle may be associated with sets of frequency resources that are spaced in frequency from each other by a maximum frequency spacing.

Abstract: A user equipment (UE) may utilize frequency domain (FD) compression for reporting channel state information (CSI) including a precoding matrix indicator (PMI). The UE may receive a CSI configuration specifying a first set of configured FD units to be reported. The UE may determine a first number of FD units based on the first set of configured FD units. The UE may select a second number of FD units that is greater than or equal to the first number of FD units. The UE may calculate, for one or more layers, a PMI for a second set of FD units including a number of FD units equal to the second number of FD units. The UE may allocate, according to a mapping rule, a number of PMIs for the first set of FD units to a subset of the PMIs for the second set of FD units.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a first device to perform data validation with one or more other devices. For example, a device may generate data at components associated with the device. To validate at least a portion of the data, the device may establish a connection with other devices. In some examples, the device may determine a portion of the data to validate based on a capability of the other devices to generate data that corresponds to the portion of data. The device may exchange data with the other devices and determine a validity of data generated at the device in response.

Abstract: Techniques for implicitly configuring resources for radio link monitoring or beam failure detection. An example method generally includes identifying that RLM resources or BFD resources are configured implicitly by at least in part: obtaining TCI states, for PDDCH CORESETs, obtaining an indication that at least one of the TCI states is activated to become an active TCI state of the PDCCH CORESETs, identifying one or more CSI-RS resources configured in the at least one of active TCI states of the PDCCH CORESETs, and if the UE does not support RLM or BFD based on the CSI-RS or the one or more CSI-RS resources are AP or SP, determining a SS block for RLM or BFD that has a QCL relationship with the one or more CSI-RS resources of the at least one of active TCI states; and performing RLM or BFD based on the SS block.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information configuring one or more occasions of a periodic channel state information reference signal (P-CSI-RS) without associated quasi co-location (QCL) information for the one or more occasions of the P-CSI-RS. The UE may receive an occasion of the P-CSI-RS, of the one or more occasions of the P-CSI-RS, using a QCL relation determined based at least in part on whether a physical downlink shared channel (PDSCH) is scheduled for a same set of symbols as the occasion of the P-CSI-RS. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, via a first component carrier, control information that triggers transmission of an aperiodic reference signal in a second component carrier. The UE may identify a quasi co-location (QCL) assumption for reception of the aperiodic reference signal in the second component carrier based at least in part on a control resource set not being configured for the second component carrier. The UE may then monitor for the aperiodic reference signal of the second component carrier based on the QCL assumption. In some cases, the UE may transmit a measurement report to a base station based on a measurement of the reference signal.

Abstract: Apparatus, methods, and computer-readable media for facilitating adaptive precoder updating for channel state feedback are disclosed herein. An example method of wireless communication at a UE includes selecting a second wideband component W1 of a second PMI, the second PMI including the second wideband component W1 and a second subband component W2, and the selecting of the second wideband component W1 being based at least on a determining of whether to reuse for the second wideband component W1 a first wideband component W1 of a first PMI previously determined based on received first CSI-RS, the first PMI including a first wideband component W1 and a first subband component W2. The example method also includes determining the second PMI based on a received second CSI-RS, the second wideband component W1, and the second subband component W2. The example method also includes reporting the determined second PMI to a base station.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for dynamic updates to beam failure detection (BFD) reference signals (RSs) and path loss RS using medium access control-control element (MAC-CE) or downlink control information (DCI). For example, the quasi co-location (QCL) of periodic CSI-RS may be dynamically updated by the MAC-CE or DCI when the periodic CSI-RS is for BFD RS. Also, a semi-persistent CSI-RS or aperiodic CSI-RS may act as a BFD RS. An enhanced update procedure may be used to update the path loss RS dynamically using MAC-CE or DCI. In some cases, the path loss RS parameters updated via MAC-CE or DCI may overwrite the previously RRC configured path loss RS parameters. In another example, if the path loss RS is not configured, then the path loss RS by default may be the spatial relation reference signal of the corresponding uplink beam.

Abstract: Methods, systems, and devices for wireless communications are described. An exemplary method includes receiving a signal corresponding to a frequency band, scanning for communications activity within the frequency band, wherein scanning for communications activity within the frequency band comprises performing a correlation calculation on samples of the signal, and determining whether to attempt a connection establishment within the frequency band based at least in part on the correlation calculation on samples of the signal. When the scanning identifies an indication of activity, a scanning device may attempt to establish a connection with a base station within the frequency band. When the scanning identifies an indication of no activity, a scanning device may refrain from attempting to establish a connection with a base station within the frequency band, and may perform the correlation-enhanced frequency scanning on a different frequency band.
