Method and device for transmitting and receiving aperiodic reference signal

摘要

Disclosed are a method and a device for transmitting and receiving an aperiodic reference signal. The method for receiving an aperiodic reference signal comprises: allowing a reference signal receiving device to determine a radio resource area that can be calculated by environmental information from a first reference signal transmission device, and to transmit an aperiodic reference signal to the first reference signal transmission device by including first instruction information which instructs the aperiodic reference signal to be transmitted in the radio resource area; transmitting the aperiodic reference signal by including second instruction information which instructs a second reference signal transmission device, to which a periodic reference signal is to be transmitted in said radio resource area; and receiving the aperiodic reference signal from the first reference signal transmission device in the radio resource area.

1. A method of receiving a sounding reference signal (SRS) by a base station, the method comprising:
transmitting, to User Equipment (UE), at least one parameter set comprising an antenna configuration and a transmission bandwidth configured to transmit an aperiodic sounding reference signal (A-SRS) by Radio Resource Control (RRC) signaling; generating a radio control signal for a Downlink Control Signal (DCI) Format 4 comprising 2-bits or 3-bits of information instructing the UE to transmit the A-SRS in a radio resource area and indicating one of the at least one parameter set; transmitting, to the UE, the radio control signal; and receiving the A-SRS in the radio resource area by the indicated parameter set including the antenna configuration and the transmission bandwidth, wherein the 2-bits or 3-bits of information indicate A-SRS activation state or no activation state, and state ‘0’ of the 2-bits or 3-bits of information indicates the no A-SRS activation state, state ‘1’ of the 2-bits or 3-bits of information indicates a first parameter set of the A-SRS activation state, state ‘2’ of the 2-bits or 3-bits of information indicate a second parameter set of the A-SRS activation state, and state ‘3’ of the 2-bits or 3-bits of information indicates a third parameter set of the A-SRS activation state.
