Allocation of bandwidth among communication links in distributed antenna system

A telecommunications system comprising:

• a plurality of remote units configured to transmit downlink signals using multiple transmission modes to terminal devices;
• and
• at least one processor configured to:
• identify a first group of terminal devices, wherein the first group of terminal devices receives first downlink signals using a first transmission mode;
• identify a second group of terminal devices, wherein the second group of terminal devices receives second downlink signals using a second transmission mode;
• assign a first percentage of frequency resources to the first group of terminal devices based on the first transmission mode;
• assign a second percentage of frequency resources to the second group of terminal devices based on the second transmission mode;
• configure the first downlink signals provided to each remote unit associated with the first group of terminal devices using a first signal power that is associated with the first percentage of frequency resources for the first group of terminal devices associated with the respective remote unit, wherein the first signal power corresponds to a level that compensates for a power level of the first downlink signals being divided by a splitter prior to providing the first downlink signals to the remote units;
• and
• configure the second downlink signals provided to each remote unit associated with the second group of terminal devices using a second signal power that is associated with the second percentage of frequency resources for the second group of terminal devices associated with the respective remote unit, wherein the second signal power corresponds to a level that compensates for a power level of the second downlink signals being combined by a splitter prior to providing the second downlink signals to the remote units.

A telecommunications system comprising:

• a plurality of remote units for transmitting downlink signals using a transmission mode to terminal devices;

• wherein the base station comprises at least one processor configured to:
• identify a first group of terminal devices, wherein the first group of terminal devices receives first downlink signals transmitted by the base station using a first transmission mode,
• identify a second group of terminal devices, wherein the second group of terminal devices receives second downlink signals transmitted by the base station using a second transmission mode;
• assign a first percentage of frequency resources to the first group of terminal devices based on the first transmission mode,
• assign a second percentage of frequency resources to the second group of terminal devices based on the second transmission mode,
• configure the first downlink signals transmitted by the base station to the first group of terminal devices using a first signal power that is associated with the first percentage of frequency resources for the first group of terminal devices, and
• configure the second downlink signals transmitted by the base station to the second group of terminal devices using a second signal power that is associated with the second percentage of frequency resources for the second group of terminal devices;
• and
• a splitter in a signal path between the head-end unit and the remote units, the splitter configured to:
• receive the first downlink signals intended for the first terminal devices and the second downlink signals intended for the second terminal devices,
• divide a power level of the first downlink signals to generate modified first downlink signals,
• combine a power level of the second downlink signals to generate modified second downlink signals,
