METHOD AND APPARATUS FOR TRANSMITTING UPLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for transmitting an uplink signal. The method for transmitting an uplink signal from a terminal in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving configuration information about candidates in a parameter set for a reference signal for physical uplink shared channel (PUSCH) modulation; receiving information indicating a specific set among the candidates in the parameter set; and generating a sequence of the reference signal using the specific set and transmitting the generated reference signal to a base station, wherein the information indicating the specific set may have a maximum value of the minimum distance between a circular shift index of the reference signal generated by a terminal using the specific set and a circular shift index of a reference signal generated by another terminal using the specific set.

1. A method of transmitting, by a user equipment (UE), an uplink signal in a wireless access system, the method comprising:
receiving configuration information regarding one or more parameter set candidates related to a reference signal for demodulation of a physical uplink shared channel (PUSCH); receiving information indicating a specific parameter set from among the parameter set candidates; generating a sequence of the reference signal using the specific parameter set and transmitting the generated reference signal sequence to a base station (BS), wherein the information indicating the specific parameter set further indicates one of a plurality of cyclic shift (CS) indices, and the CS indices have values maximizing a minimum distance between maximum CS indices.
