Described embodiments provide controlling signal transmission in a plurality of radio units. The plurality of radio units may be coupled to a digital unit. The digital unit may be spatially separated from the plurality of radio units. Signal quality measurements may be received from multiple radio units when a user equipment is located within an overlapping service area of the multiple radio units. Determination may be made as to whether to simultaneously use at least two of the multiple radio units to transmit a data signal to the user equipment based on the received signal quality measurements. At least two of the multiple radio units may be controlled to transmit a same data signal to the user equipment using a same channel based on the determination result. |
