An operating method of a wireless communication device configured to perform wireless communication with a cell. The method involves identifying, from a downlink signal received from the cell, an electromagnetic field state associated with an antenna of the wireless communication device. A power compensation mode for compensating transmission power of a sounding reference signal is selected based on the identified electromagnetic field state. The transmission power of the sounding reference signal is compensated based on the selected power compensation mode. The sounding reference signal is transmitted with the compensated transmission power through the antenna to the cell.

A method of picking up a die may include classifying a pickup region of a diced wafer, in which targeted pickup dies are placed, into first to n-th regions and performing a pickup step on dies in the first to n-th regions. The first region may include first dies, which are outermost dies of the targeted pickup dies. An (x+1)-th region may include regions, occupied by dies adjacent to at least one of x-th dies in an x-th region and proximate to a center of the pickup region in relation to the x-th region, n may be a natural number, and x may be an arbitrary natural number that is smaller than the n. The n-th region may have a rectangular shape, and a quantity of n-th dies in the n-th region in contact with a short side of the n-th region may be one or two.
