Abstract: The present invention relates to a distributed radio base station, and provides a distributed radio base station, including: one or more base units (BUs) configured to process digital signals; and one or more radio units (RUs) installed in one or more target service areas, and configured to wirelessly communicate with pieces of user equipment; wherein each of the BUs is coupled to a cell group, composed of a set of RU groups each formed by grouping one or more of the RUs, over a transport network.

Abstract: A method of driving a display panel includes adjusting a level of a data sustaining voltage or an on bias voltage during an on bias compensating period, applying the on bias voltage to pixels through data lines during an on bias period, which is subsequent to the on bias compensating period, to adjust a voltage level of control electrodes of driving transistors of the pixels, initiating a voltage of anode electrodes of organic light emitting elements of the pixels during an initiating period, applying data voltages to the pixels through the data lines during a scanning period, and turning on the organic light emitting elements of the pixels during an emission period.

Abstract: The present invention provides a method of HARQ processing for uplink transmission in a distributed radio base station including at least one base unit (BU) configured to process digital signals and one or more radio units (RUs) installed in one or more target service areas and configured to wirelessly communicate with one or more pieces of user equipment (UEs), wherein the BU is coupled to each cell group over a transport network, the method including: a first step of forming, by the BU, radio unit groups by grouping the RUs for the individual pieces of UE; a second step of selecting, by the BU, any one of RUs, belonging a radio unit group for each of the pieces of UE, as an HARQ manager; and a third step of transmitting, by the BU, an HARQ response to the UE via the RU, which is the selected HARQ manager.
