Patent Images
1. A method for processing an uplink signal, the method comprising:
- receiving a first uplink signal directly from user equipment;
delaying the received first uplink signal by using uplink delay information;
receiving a second uplink signal indirectly from user equipment through at least one repeater connected to a radio unit;
combining the delayed first uplink signal and the second uplink signal; and
transmitting the combined signal to a digital unit.

Abstract
Described embodiments provide a method for processing an uplink signal in a radio unit. A first uplink signal may be received directly from user equipment. The received uplink signal may be delayed using uplink delay information. A second uplink signal may be received indirectly from user equipment through at least one repeater connected to the radio unit. The delayed first uplink signal and the second uplink signal may be combined and transmitted to a digital unit.

12. A radio unit located in a base station of a virtual radio network and connected to at least one repeater, the radio unit comprising:
-
a receiver configured to receive first uplink signals from user equipment, to receive second uplink signal from the at least one repeater, and to receive downlink signals from a digital unit; a delay unit configured to receive uplink delay information and downlink delay information, to delay the first uplink signal using the uplink delay information, and to delay first downlink signals of the received downlink signals using the downlink delay information; a combiner configured to combine the delayed first uplink signal with the second uplink signal; a transmitter configured to transmit the combined uplink signal to the digital unit, to transmit the delayed first downlink signal directly to the user equipment, and to transmit a second downlink signal of the received downlink signals to the at least one repeater. - View Dependent Claims (13, 14, 15, 16)
