Abstract

Provided is a method of outputting a synchronization signal in a communication node comprising: receiving communication connection information from a terminal, identifying detectable position information of a synchronization signal block (SS block) included in the communication connection information, setting a position of the SS block based on the identified detectable position information, and outputting the SS block based on the set position.

First claim

What is claimed is:

1. A method of outputting to a terminal a synchronization signal by a communication node, the method comprising:
receiving communication connection information from the terminal, the communication connection information comprising position information of a synchronization signal (SS) block for the terminal;
identifying the position information of the SS block included in the communication connection information;
setting a position of the SS block for the terminal based on the identified position information; and
outputting the SS block based on the set position,
wherein the setting of the position of the SS block for the terminal comprises, when a plurality of frequency bands for the SS block corresponding to the position information are identified, selecting a frequency band based on whether each of the plurality of frequency bands is occupied by another terminal.

2. The method of claim 1 , wherein the setting of the position of the SS block comprises setting an orthogonal frequency division multiplexing (OFDM) symbol position and a subcarrier position of the SS block so that the SS block is output at a frequency included in a frequency band corresponding to the position information.

3. The method of claim 1 , wherein the communication connection information comprises at least one of frequency-in-use information and available bandwidth information of the terminal.

4. The method of claim 3 , further comprising: allocating a communication resource for communication with the terminal based on at least one of the frequency-in-use information and the available bandwidth information included in the communication connection information.

5. The method of claim 1 , wherein the communication node comprises a base station or a repeater.

6. A communication node comprising:
a terminal information receiver configured to receive communication connection information from a terminal, the communication connection information comprising position information of a synchronization signal (SS) block for the terminal;
a terminal information processor configured to identify the position information of the SS block by processing the received communication connection information; and
an SS block output adjuster configured to set a position of the SS block for the terminal based on the position information, and output the SS block based on the set position,
wherein when a plurality of frequency bands corresponding to the position information are identified, the SS block output adjuster is further configured to select a frequency band based on whether each frequency band is occupied by another terminal.

7. The communication node of claim 6 , wherein the SS block output adjuster is configured to set an orthogonal frequency division multiplexing (OFDM) symbol position and a subcarrier position of the SS block so that the SS block is output at a frequency included in a frequency band corresponding to the position information.

8. The communication node of claim 6 , wherein the communication connection information comprises at least one of frequency-in-use information and available bandwidth information of the terminal.

9. The communication node of claim 8 , wherein a communication resource for communication with the terminal is allocated based on at least one of the frequency-in-use information and the available bandwidth information included in the communication connection information.

10. The communication node of claim 6 , wherein the communication node comprises a base station or a repeater.
