METHOD FOR TRANSMITTING SIGNAL AND APPARATUS FOR SAME

摘要

The present invention relates to a method for enabling a terminal to transmit an uplink signal in a wireless communication system for supporting carrier aggregation of a plurality of cells by including a first cell set to have a first type cyclic prefix and a second cell set to have a second type cyclic prefix, and an apparatus for the same, the method comprising the steps of: transmitting an uplink physical channel signal through the first cell in a specific sub-frame; and transmitting a sounding reference signal through the second cell in the specific sub-frame, wherein the second type cyclic prefix length is greater than the first type cyclic prefix length, a transmission interval of the sounding reference signal is overlapped with a transmission interval of the uplink physical channel signal during a specific interval, and the transmission of the sounding reference signal is omitted during at least the specific interval when the transmission power of the terminal does not exceed a specific value.

1. A method for transmitting an uplink signal by a user equipment in a wireless communication system for supporting carrier aggregation of a plurality of cells comprising a first cell configured to have a first type cyclic prefix and a second cell configured to have a second type cyclic prefix, the method comprising:
transmitting an uplink physical channel signal in a specific subframe through the first cell; and transmitting a sounding reference signal in the specific subframe through the second cell, wherein a length of the second type cyclic prefix is greater than a length of the first type cyclic prefix, and wherein when a transmission period of the sounding reference signal and a transmission period of the uplink physical channel signal are overlapped with each other during a specific period and a transmission power of the user equipment does not exceed a specific value, a transmission of the sounding reference signal is skipped during at least the specific period.
