PROCESSING DIGITAL SIGNAL

摘要

Described embodiments provide a digital unit for controlling a plurality of radio units to transmit a signal to user equipment. The digital unit may determine whether user equipment is located at an overlapping service area of a first radio unit and a second radio unit and control the first radio unit to transmit a signal to the user equipment using the first antenna and control the second radio unit to transmit the same signal to the user equipment using the second antenna when the user equipment is located in the overlapping service area. A transmission pattern of the first antenna of the first radio unit may be different from a transmission pattern of the second antenna of the second radio unit.
