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. Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support methods for selection of antenna arrays and beamforming feedback. In some cases, a user equipment (UE) may monitor for an antenna blockage condition at the UE and may select a set of antenna arrays for the UE for communications between the UE and a network entity based at least in part on whether the antenna blockage condition is detected, the set of antenna arrays selected from a multiple predetermined sets of antenna arrays of the UE. Additionally, the UE may transmit, to the network entity, a message indicative of whether the antenna blockage condition is detected and may communicate with the network entity using the set of antenna arrays in accordance with whether the antenna blockage condition is detected.

Abstract: This disclosure provides systems, methods, apparatuses, and computer programs encoded on computer storage media, for wireless communication. Various aspects support beam switching and changing antenna array configurations for communicating in a near field range. In some examples, a user equipment (UE) may transmit a beam group indicator to a network entity, and the UE and the network entity may perform beam switching operations associated with switch communication beams in association with changes to a distance between the UE and the network entity. In some such examples, the beam switching may switch from using beam weights for communications in a far field range to beam weights for communications in a near field range. Additionally or alternatively, the network entity may change configurations of an antenna array used to communicate with the UE in association with changes to the distance. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may generate blockage transformation information associated with one or more blockage scenarios based on one or more adaptive beam weights used for blockage mitigation at the UE associated with respective positions of a body or hand relative to one or more antennas of the UE. The blockage transformation information may include an indication of a transformation matrix used for a transformation of a first electric field matrix associated with a non-blockage scenario to a second electric field matrix associated with a blockage scenario. The UE may transmit a message indication the blockage transformation information to a machine learning server, which may generate adaptive beam weights for hand or body blockage mitigation based on messages received from multiple UEs. The machine learning server may transmit the adaptive beam weights to a UE entering a network.
