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.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a control message indicating a set of sampling beams defined for the UE. The UE may measure a set of received signal strengths for communications from a wireless node associated with a set of linear combinations of sampling beams from the set of sampling beams defined at the UE. The UE may calculate a set of entries of a channel covariance matrix based on the set of received signal strengths of the set of linear combinations of the sampling beams from the set of sampling beams defined for the UE. As such, the UE may communicate with the wireless node based on applying a set of beam weights to an antenna array of the UE. In some examples, the set of beam weights may be based on the channel covariance matrix.
