Abstract
The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transmitting an uplink signal. A method for transmitting an uplink signal at a UE in a wireless communication system includes, when a virtual cell ID for a reference signal for demodulation of a physical uplink channel is provided, generating a sequence of the reference signal on the basis of the virtual cell ID, and transmitting the generated reference signal to an eNB. A sequence shift pattern of the reference signal can be determined on the basis of the virtual cell ID.
Claims11
A method for transmitting an uplink signal at a user equipment (UE) in a wireless communication system, the method comprising:
- when a virtual cell ID nIDPUSCH for a reference signal for demodulation of a physical uplink shared channel (PUSCH) is provided, generating a sequence of the reference signal on the basis of nIDPUSCH;
- and
- transmitting the generated reference signal to an eNB,
- wherein a sequence shift pattern fssPUSCH of the reference signal is determined according to fssPUSCH=nIDPUSCH mod 30,
- wherein mod denotes a modulo operation.
A UE device for transmitting an uplink signal, comprising:
- a receiver;
- a transmitter;
- and
- a processor,
- wherein, when a virtual cell ID nIDPUSCH for a reference signal for demodulation of a PUSCH is provided, the processor is configured to generate a sequence of the reference signal on the basis of nIDPUSCH and to transmit the generated reference signal to an eNB through the transmitter,
- wherein a sequence shift pattern fssPUSCH of the reference signal is determined according to fssPUSCH=nIDPUSCH mod 30,
- wherein mod denotes a modulo operation.
