Abstract
Methods and apparatus for distinguishing between an antenna of a user equipment (UE) being blocked by a cover or by human tissue. The transmission power of uplink signals may be adjusted accordingly, with higher transmission power for open space (OS) or a cover and lower transmission power for tissue. One example method for wireless communications by a UE generally includes receiving a plurality of cross-polarization captures from multiple antenna arrays of the UE; detecting that the cross-polarization captures correspond to a first OS circle in an in-phase/quadrature (IQ) plane out of a set of possible OS circles for the UE; based on the detection, assigning the first OS circle as an active OS circle for the UE and deactivating other possible OS circles in the set; determining an environmental scenario corresponding to the active OS circle; and transmitting a signal using a transmission power based on the determined scenario.
