摘要： 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.

摘要： An operating method of a communication device for providing a beamformed transmission signal to a plurality of terminals may include determining a target transmission vector based on an area restriction condition for each of the plurality of terminals, generating a beam selection matrix for selecting some of a plurality of antennas based on the target transmission vector and a beam selection condition, generating a precoding matrix based on the target transmission vector and the beam selection matrix, and generating a transmission signal based on the beam selection matrix and the precoding matrix.
