Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) or relay node may transmit a beam report indicating a polarization layer mismatch (achievable rates are different for the first and second polarizations, or positioning estimation accuracy is different for the first and second polarizations). The report may include an indication of an imbalance in signal strength, an estimation error for the two polarizations, one or more beam pairs that are not supported across the two polarizations, a preferred polarization, or a combination thereof. In response to the beam report, the network entity may adjust one or more parameters, and may transmit accordingly. A relay node may indicate non-co-located polarization array construction via capability information. The UE may then transmit feedback indicating a direction of steered beams at the UE. The relay node performs relay operations based on transmission characteristics selected from the beam direction information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an insufficient calibration message based at least in part on a trigger condition that indicates that a calibration of the wireless communication device is insufficient. The wireless communication device may receive a set of signals associated with calibration assistance in response to the insufficient calibration message. Numerous other aspects are described.

Abstract: Method and apparatus for sharing dynamic capability levels of calibration to other devices in a network. The apparatus transmits, to a second UE, a first calibration capability message indicating a first set of one or more levels of calibration capabilities. The apparatus performs an online calibration procedure with the second UE based at least on the first calibration capability message indicating the first set of one or more levels of the calibration capabilities. The apparatus may receive, from the second UE, a second calibration capability message associated with the second UE indicating a second set of one or more levels of the calibration capabilities for the second UE. The apparatus may transmit a beamforming loss indication indicating a loss in beamforming array gain with use of an uncalibrated amplitude or phase settings corresponding to at least one of an operating frequency, a temperature level, or a gain stage level.

Abstract: A first wireless device and a second device may negotiate a configuration of an RF chain calibration process with each other. The configuration of the RF chain calibration process may include a number of calibration rounds. The second wireless device may exchange, in each calibration round in the number of calibration rounds, at least one RS and at least one feedback message with the first wireless device. The second wireless device may identify one or more calibration adjustment parameters for the second wireless device based on the RF chain calibration process. The second wireless device may communicate with another wireless device based on the one or more calibration adjustment parameters.

Abstract: Aspects are provided which allow AGC symbols to be applied for identifying or indicating target Rx UEs of sidelink communications from Tx UEs. A Tx UE transmits an AGC signal to a Rx UE in a RB associated with the Rx UE. The Rx UE receives the AGC signal from the Tx UE. The Tx UE transmits sidelink data to the Rx UE after the AGC signal. The Rx UE decodes sidelink data from the Tx UE in response to the AGC signal being received in a RB associated with the Rx UE. The Rx UE refrains from decoding the sidelink data from the Tx UE in response to the AGC signal being received in a different RB than the RB associated with the Rx UE. In this way, Rx UEs may save monitoring and processing power and time in receiving and decoding sidelink communications.
