    Abstract: An antenna is described. The antenna includes a first plurality of first elements. Each of the first elements is dual polarized and configured to support a first set of bands and a second set of bands that is mutually exclusive from the first set of bands. The antenna also includes a second plurality of second elements. Each of the second elements is dual polarized and configured to support the second set of bands. The second plurality of second elements is interleaved with the first plurality of first elements.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to report feedback to a base station to address polarization impairments in multiple-input multiple-output (MIMO) communications. The UE and the base station may establish a communications link using a pair of orthogonally polarized beams, where the pair of polarized beams may be selected based on a beam sweep procedure. The UE may transmit a report to the base station indicating one or more polarization parameters associated with beam pairs identified in the beam sweep procedure, such as one or more orthogonality parameters, one or more polarization parameters relating to one or more beam pairs, or one or more angular spread parameters. Based on the report, the base station may transmit a beam configuration to the UE for polarization MIMO communications.

    Abstract: An apparatus is disclosed for an antenna with a conductive cage. In an example aspect, the apparatus includes a ground plane with at least one opening. The apparatus also includes at least one antenna assembly with at least one radiating element, at least one feed via, and a conductive cage. The radiating element is implemented on a first plane that is substantially parallel to the ground plane. The feed via is connected to the at least one radiating element and is configured to connect to at least one transmission line through the opening. The conductive cage includes at least three ground vias, which are connected to the ground plane at positions that are distributed around the opening. Lengths of the at least three ground vias extend a portion of a distance between the ground plane and the radiating element.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use transmissions causing power density exposure (PDE) to nearby users. To reduce the PDE of an antenna module (e.g., below a maximum PDE threshold), the UE may implement a shielding strip around the antenna module. For example, the antenna module may include a substrate having a first surface and a set of antenna elements on the first surface. The shielding strip may enclose the set of antenna elements of the antenna module and extend away from the first surface above the antenna elements. The shielding strip may reduce PDE outside a field of view of the antenna module. Additionally, in some cases, the placement of the antenna module in the UE and the materials used for constructing the UE may further reduce PDE.

    Abstract: Methods, systems, and devices for wireless communications are described that support beam correlation across frequency bands for beam selection in the event of a frequency switch. For example, a base station may determine a configuration indicating a mapping between a set of beam identifiers (IDs) and a set of angle coverage ranges for a set of frequency ranges which corresponds to a user equipment's (UE) operating frequencies. In some examples, the UE may undergo a frequency switch and switch from a first operating frequency to a second operating frequency. The UE may select a beam ID based on the mapping and communicate with the base station via the second operating frequency using a beam associated with the selected beam ID.

    Abstract: Wireless communications systems and methods related to mitigation of calibration errors are provided. A base station (BS) transmits, via an antenna array including a plurality of antenna elements, a first communication signal using a first number of the plurality of antenna elements and a first transmission power level to a user equipment (UE). The BS receives from at least one UE, a measurement report based on the first communication signal. The BS transmitting a second communication signal using a second number of the plurality of antenna elements and a second transmission power level based on the one or more measurement reports. At least one of the first number of the plurality of antenna elements is different from the second number of the plurality of antenna elements, or the first transmission power level is different from the second transmission power level. Other aspects and features are also claimed and described.
