    Abstract: Methods, systems, and devices for wireless communications are described. An assistive node may include circuitry for operating in an amplifying mode and operating in a reflecting mode. The assistive node may transmit a message to a network entity indicating that the assistive node is capable of operating in an amplifying mode or a reflecting mode. The network entity may transmit scheduling information to the assistive node for a packet transmission to be reflected or amplified by the assistive node to a wireless device, for example, because a direct path between the network entity and the wireless device is blocked. The network entity may transmit control signaling to the assistive node configuring the assistive node to either reflect or amplify the packet transmission to the wireless device. The assistive node may reflect or amplify the packet transmission to the wireless device based on the control signaling.

    Abstract: Methods, systems, and devices for wireless communications are described for mitigation of blockages in wireless signals between wireless devices. A UE may detect that a blockage is present (e.g., a hand blockage), such as by detecting that a received signal strength from a transmitting device (e.g., a base station or access network entity) has dropped by greater than a threshold value. Based on the blockage detection, the UE may measure an amplitude of one or more reference signals at one or more antenna elements of multiple antenna elements. The UE may also measure one or more reference signals for one or more phase shifter values that are applied to the multiple antenna elements. The UE may determine a set of amplitude weightings, and a set of phase weightings, for the multiple antenna elements based on the measuring, and apply the sets of weightings for communications with the transmitting device.

    Abstract: Methods, systems, and devices for wireless communications are described. One method may inlcude a base station or other device estimating an intended coverage area of all possible communication devices that are to be serviced by the base station or other device. The base station or other device may dynamically optimize at least one transmission metric such as a codebook, in response to a change in the coverage area. Another method may include a base station estimating a dynamic coverage area of a set of all possible user equipments or devices to be serviced, and dynamically optimizing a codebook structure in response to a change in the coverage area. Another method may include the base station determining a use-case of the set of all possible user equipments to be serviced by the base station, and hard-coding a metric corresponding to the use case.

    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: 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.
