METHOD AND APPARATUS FOR TRANSMITTING UPLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

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 first virtual cell ID for a physical uplink control channel and a second virtual cell ID for a physical uplink shared channel can be provided as separate parameters.

1. A method for transmitting an uplink signal at a user equipment (UE) in a wireless communication system, the method comprising:
when a first virtual cell ID (VCI) for a first reference signal for demodulation of a physical uplink control channel (PUCCH) is provided, generating a sequence of the first reference signal on the basis of the first VCI; and transmitting the generated first reference signal to an eNB, wherein the first VCI is provided as a parameter separated from a second VCI for a second reference signal for demodulation of a physical uplink shared channel (PUSCH).
