Abstract
Provided are a method and an apparatus for transmitting an uplink (UL) reference signal (RS) in a wireless communication system. A first user equipment (UE) served through a macro eNodeB (eNB) generates a first UL RS on the basis of a first indicator and transmits the generated first UL RS. A second UE served through a pico eNB having the same cell identifier (ID) as the macro eNB generates a second UL RS on the basis of a second indicator and transmits the generated second UL RS. The bandwidth to which the first UL RS is transmitted is overlapped with the bandwidth to which the second UL RS is transmitted.

16. A method for transmitting, by a user equipment (UE), a reference signal in a wireless communication system, the method comprising:
-
configuring a virtual cell identity (ID) which is different from a physical cell ID; obtaining a sequence group number of a base sequence by using the virtual cell ID; generating the base sequence by using the sequence group number; and transmitting a reference signal, which is generated by using the base sequence, to an eNodeB (eNB). - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A user equipment (UE) in a wireless communication system, the UE comprising:
-
a radio frequency (RF) unit for transmitting or receiving a radio signal; and a processor coupled to the RF unit, and configured to; configure a virtual cell identity (ID) which is different from a physical cell ID; obtain a sequence group number of a base sequence by using the virtual cell ID; generate the base sequence by using the sequence group number; and transmit a reference signal, which is generated by using the base sequence, to an eNodeB (eNB).
