Methods and apparatus for user equipment to differentiate human grip from protective covers

A method for wireless communications by a user equipment (UE), comprising:

• transmitting a first signal from the UE;
• receiving a plurality of signals at the UE based on the transmitted first signal;
• determining values for at least two different types of parameters based on the received plurality of signals;
• determining an environmental scenario for the UE based on the values for the at least two different types of parameters;
• and
• transmitting a second signal using a transmission power based on the determined environmental scenario, wherein determining the environmental scenario comprises:
• determining a boundary based on a relationship between the at least two types of parameters;
• and
• determining whether one of the at least two types of parameters is on a first side of the boundary or a second side of the boundary, wherein:
• the second signal is transmitted using a relatively lower transmission power if the one of the at least two types of parameters is on the first side of the boundary;
• and
• the second signal is transmitted using a relatively higher transmission power if the one of the at least two types of parameters is on the second side of the boundary.
