Abstract
Provided are a mobile communication system, a digital unit, and a method of establishing a joint transmission area in the system. When the digital unit determines that a terminal is located in a joint transmission area based on signal strength values received from two of radio units and transmission powers of the two radio units, the digital unit adjusts the joint transmission area depending on the load on the network including the two radio units belong in order to allow the two radio units to perform a joint transmission function to send at least one of the same signal and a spatiotemporally coded signal of the same data to the terminal.
