Abstract: The present invention discloses a signal output apparatus, a board, and a signal output method. UE signals to be output are grouped, and UE signals having similar powers are combined and are then output by using one same antenna. This resolves a problem that a low-power UE signal is distorted when a large quantity of UE signals are output from an air interface.
