METHOD FOR TRANSMITTING AND RECEIVING APERIODIC SOUNDING REFERENCE SIGNAL, TERMINAL AND BASE STATION THEREOF

摘要

The present invention provides a method for transmitting and receiving an aperiodic sounding reference signal, a terminal and a base station thereof which include: a step of receiving at least two parameters to determine a time-frequency resource on which an aperiodic sounding reference signal is transmitted through upper-layer signaling; a step of receiving a parameter set having a part of parameters through at least one between PDCCH or EPDCCH; a step of receiving a signal for triggering an aperiodic sounding reference signal through at least one between the PDCCH or EPDCCH; and a step of transmitting an aperiodic sounding reference signal by frequency-hopping a time-frequency resource according to the parameter received through the upper-layer signaling and the parameter included in the parameter set received through at least one between the PDCCH or EPDCCH.;COPYRIGHT KIPO 2014;[Reference numerals] (AA) Aperiodic SRS which does not frequency-hop; (BB) Frequency; (CC) Time; (DD,GG) Subframe; (EE,HH) Entire frequency range of interest; (FF) Frequency hopping aperiodic SRS
