Abstract: Methods, systems, and devices for wireless communications are described. To support communications across a wideband, a base station and user equipment (UE) may communicate across the wideband using a set of sub-bands that span the carrier bandwidth (e.g., the wideband). In some cases, the UE may transmit, to the base station, an indication of a capability of the UE to communicate a wideband communication with the base station via the set of sub-band based communications with the base station. The UE may receive, from the base station (and, in some cases based on the capability of the UE), a configuration for communicating with the base station in the carrier bandwidth using the set of sub-bands. Then, the UE may communicate with the base station in the carrier bandwidth using one or more of the set of sub-bands in accordance with the configuration.

Abstract: Methods, systems, and devices for wireless communications are described. To support a reliable array response for wideband communications, a base station may configure a set of transmission instances for a set of signals distributed across a wideband carrier bandwidth. At least one transmission instance of the set of transmission instances may be configured in each sub-band of the carrier bandwidth. The base station may transmit the set of signals in the configured transmission instances to a user equipment (UE). The UE may receive the set of signals distributed across the carrier bandwidth and may measure, for the signals, a set of signal measurements corresponding to the set of sub-bands. Based on the signal measurements, the UE may determine a set of communication beams for the set of sub-bands. Using one or more of the determined communication beams, the UE may communicate with the base station in the carrier bandwidth.
