    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.

    Abstract: Methods, systems, and devices are described for wireless communication using the mmW spectrum. In particular, an antenna structure may be designed to integrate with an external housing of a wireless communication device. For example, the external housing may include a cavity that facilitates reception and/or transmission of radio frequency communication signals by an antenna element of the antenna structure. Such an antenna structure may be designed to be relatively compact to deal with the limited real estate available on modern wireless communication devices (e.g., cellular telephones).

    Abstract: A wireless device with built-in self test (BIST) capability for testing/calibrating transmit and receive circuits is disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) includes a first circuit and a second circuit. The first circuit (e.g., a transmitter or a mixer) provides a test signal to at least one transmit path. The test signal is electro-magnetically coupled from the output of the at least one transmit path to a test signal line. For example, the test signal may be provided from the at least one transmit path via at least one antenna feed line to at least one antenna element and may be electro-magnetically coupled from the at least one antenna feed line to the test signal line. The second circuit (e.g., a buffer, a receiver, or a mixer) processes a received test signal from the test signal line.

    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.
