Abstract
One embodiment of the present invention relates to a method whereby a second node transmits/receives signals in a full duplex radio (FDR) system, the method for transmitting/receiving signals in an FDR system comprising steps in which: the second node transmits a signal to a first node as the second node receives a signal from the first node; the second node transmits Tx/Rx capability information to a third node if the transmission of the signal to the first node is completed during the reception of the signal from the first node; and the second node receives a signal from the third node after transmitting the Tx/Rx capability information.
Claims12
A method of transmitting and receiving a signal, which is transmitted and received using a plurality of antennas including a first antenna and a second antenna by a second node in a FDR (full duplex radio) system, comprising:
- transmitting, by the second node, a first signal to a first node using the second antenna while receiving a second signal from the first node using the first antenna;
- when transmission of the first signal to the first node is completed before reception of the second signal from the first node is completed, transmitting, by the second node, Tx/Rx capability information to a third node;
- and
- receiving, by the second node, a third signal from the third node using the second antenna after the Tx/Rx capability information is transmitted,
- wherein the Tx/Rx capability information is information indicating that the second antenna is switchable to a receive mode for receiving the third signal from the third node.
A second node using a plurality of antennas including a first antenna and a second antenna in a FDR (full duplex radio) system, comprising:
- a transmitter and a receiver;
- and
- a processor,
- wherein the processor is configured to:
- transmit a first signal to a first node using the second antenna while receiving a second signal from a first node using the first antenna,
- when transmission of the first signal transmitted to the first node is completed before reception of the second signal from the first node is completed, transmit Tx/Rx capability information to a third node,
- receive a third signal from the third node using the second antenna after the Tx/Rx capability information is transmitted,
- wherein the Tx/Rx capability information is information indicating that the second antenna is switchable to a receive mode for receiving the third signal from the third node.
