1. A method of millimeter wave wireless communication comprising:
performing a training procedure with a software application comprising:
prompting a user to hold a user equipment (UE) in a hand grip state from a set of hand grip states pre-defined by the software application;
obtaining a first set of information associated with objects surrounding the UE, wherein the first set of information is indicative of the hand grip state; and
obtaining a set of field strength measurements across polarizations and across at least one antenna element of a set of antenna elements associated with the UE and corresponding to the hand grip state;
obtaining, after the training procedure with the software application, a second set of information associated with objects surrounding the UE; and
performing a mitigating action based on a comparison between the first set of information and the second set of information, and a correlation between the first set of information and the set of field strength measurements,
wherein the mitigating action includes:
transmitting an indication to a network entity based on the comparison,
receiving channel state information reference signals (CSI-RSs) from the network entity at an increased periodicity in response to the indication, and
performing a beam training procedure based on the CSI-RSs.
