The system transmits data between terminals of a wireless network. In the system, a base station/central controller ("BS/CC") controls transmission of data from a transmitting terminal to plural receiving terminals, where the data is ordered in slots of a control data frame ("CDF"), and where each slot is reserved for a data transmission between the transmitting terminal and a specific receiving terminal. Specifically, the BS/CC divides the plural receiving terminals into a set of power-saving terminals and a set of non-power-saving terminals, and then reserves a set of slots in the CDF for data transmission between the transmitting terminal and the power-saving terminals, and another set of slots in the CDF for data transmission between the transmitting terminal and the non-power-saving terminals. The BS/CC then issues a message over the wireless network instructing the power-saving terminals when to switch between a low-power mode and a data-receiving mode based on a location of the set of slots in the frame reserved for data transmission between the transmitter and the power-saving terminals.
