    Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may include a first set of antenna arrays disposed in a first shape and a receiving device may include a second set of antenna arrays disposed in a second shape. A first axis that intersects an antenna array of the first set of antenna arrays and a centroid of the first shape may be offset from a vertical direction by a first angular offset. A second axis that intersects an antenna array of the second set of antenna arrays and a centroid of the second shape may be offset from the vertical direction by a second angular offset that is different than the first angular offset. The transmitting device may transmit signaling to the receiving device using the first and second sets of antenna arrays, respectively based on difference between the first and second angular offsets.

    Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

    Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may receive a first signal from a second wireless device and may identify a first bundle size for a precoding resource group (PRG) based on a characteristic of the first signal and, in some examples, based on performing channel estimation on the first signal. The first wireless device may transmit a feedback message to the second wireless device indicating a second bundle size for the PRG and associated with a second signal based on identifying the first bundle size. In some examples, the first wireless device may receive the second signal on a set of resources in accordance with the second bundle size. The first signal may be an example of a channel state information reference signal (CSI-RS), and the second signal may be an example of a precoded CSI-RS or a demodulation reference signal (DMRS).

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for processing a data block into an unencoded uplink signal. The UE may determine pre-equalization parameters corresponding to the unencoded uplink signal based on the indication of the configuration. The UE may apply analog modulation and the pre-equalization parameters to the data block to form the unencoded uplink signal and transmit the unencoded uplink signal on overlapping time-frequency resources with one or more other UEs according to an over the air computation operation. The UE may determine a plurality of channel inversion coefficients based on the indication of the configuration for processing the data block into the unencoded uplink signal, measuring one or more reference signals, receiving an indication of an inversion granularity, receiving an inversion coefficient power threshold, or any combination thereof.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station over a first bandwidth part (BWP) of a carrier. The UE may receive a beam failure recovery (BFR) configuration signal configuring a set of periodic channel state information reference signals (CSI-RSs) in the first BWP and a set of synchronization signals in a second BWP. The UE may measure the set of periodic CSI-RSs in the first BWP. The UE may set a beam for communicating with the base station over the first BWP based at least in part on the measuring. The UE may be a reduced bandwidth capability and support communicating with the base station using only one BWP.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives a first control message indicating a codeblock group (CBG) scheduling configuration for scheduling CBG-based uplink communications, where the CBG scheduling configuration includes a first mapping configuration associated with uplink communications including a single codeword and a second mapping configuration associated with uplink communications including multiple codewords. The UE receives a second control message scheduling an uplink message including a set of CBGs, where the uplink message is associated with a first codeword, a second codeword, or both. The UE then transmits the uplink message in accordance with the CBG scheduling configuration, where the set of CBGs are mapped to one of the first or second codeword in accordance with the first mapping configuration, or where the set of CBGs are mapped to the first and second codewords in accordance with the second mapping configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform an operation to obtain one or more channel state information (CSI) resources (e.g., new resources) from a set of resources indicated by a CSI report configuration. For example, the UE may aggregate or separate respective resources of the set of resources to obtain one or more CSI resources. The operation may be performed based on a first number of antenna ports associated with each resource of the set of resources and a second number of antenna ports associated with a codebook configuration. Thus, performing the operation may result in the UE forming one or more CSI resources for measuring CSI on the one or more CSI resources. The UE may transmit a CSI report based on measuring the CSI for a set of reference signals received on the one or more CSI resources.
