Abstract

In an electronic device and/or an operating method of the electronic device, the electronic device may include: a communication circuit configured to perform short-range wireless communication through a first frequency band and/or a second frequency band lower than the first frequency band; and a processor, wherein the processor may be configured to identify whether a channel in the first frequency band is a non-preferred scanning channel (non-PSC), based on reduced neighbor report (RNR) information included in a signal received through the second frequency band from an external electronic device, determine a quality of a signal to be received through the first frequency band, based on transmit power control (TPC) information received from the external electronic device upon identifying that the channel in the first frequency band is the non-PSC, and determine whether to perform an operation of scanning the non-PSC, based on whether a quality of a signal to be transmitted through the first frequency band satisfies a specified condition. In addition, various embodiments are possible.

First claim

What is claimed is:

1 . An electronic device comprising:
communication circuitry configured to perform short-range wireless communication via a first frequency band and/or a second frequency band lower than the first frequency band; and at least one processor, memory storing instructions, and wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to: receive, via the second frequency band, a signal including reduced neighbor report (RNR) information and transmit power control (TPC) information from an external electronic device, identify whether the RNR information includes information on a non-preferred scanning channel (non-PSC) of the first frequency band; and in a case that the RNR information includes the information on the non-PSC of the first frequency band:
determine a quality of a signal to be received via the first frequency band, based on the TPC information and a quality of the signal received via the second frequency band; and
perform scanning the non-PSC of the first frequency band, based at least part on that the quality of the signal to be received via the first frequency band satisfying a specified condition.

2 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to determine the quality of the signal to be received via the first frequency band, based on an output strength of a signal in the first frequency band outputtable by the electronic device and a path loss of the signal in the first frequency band.

3 . The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to:
determine a path loss of the signal received via the second frequency band, based on an output strength of the signal via the second frequency and a quality of the signal received via the second frequency band, based on the TPC information; and determine the path loss of the signal in the first frequency band, based on the first frequency band, the second frequency band, and the determined path loss.

4 . The electronic device of claim 1 , wherein the specified condition comprises a condition that the quality of the signal is equal to or greater than a specified value.

5 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to refrain the communication circuitry from scanning the non-PSC of the first frequency band based at least part on that the quality of the signal to be received via the first frequency band does not satisfy the specified condition.

6 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to control a display to display an indicator indicating that an operation of scanning the channel is not performed, based on determining not to perform the operation of scanning the channel.

7 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device is configured to obtain the RNR information and/or the TPC information via an operation comprising scanning the channel via the second frequency band.

8 . The electronic device of claim 1 , wherein the first frequency band is a 6 GHZ band, and the second frequency band is a 5 GHz band or a 2.4 GHz band.

9 . An operating method of an electronic device for performing short-range wireless communication via a first frequency band and/or a second frequency band lower than the first frequency band, the method comprising:
receiving, via the second frequency band, a signal including reduced neighbor report (RNR) information and transmit power control (TPC) information from an external electronic device, identifying whether the RNR information includes information on a non-preferred scanning channel (non-PSC) of the first frequency band; and in a case that the RNR information includes the information on the non-PSC of the first frequency band:
determining a quality of a signal to be received via the first frequency band, based on the TPC information and a quality of the signal received via the second frequency band; and
performing scanning of the non-PSC of the first frequency band, based at least part on that the quality of the signal to be received via the first frequency band satisfying a specified condition.

10 . The method of claim 9 , wherein the determining of the quality of the signal to be received via the first frequency band comprises determining the quality of the signal to be received via the first frequency band, based on an output strength of a signal in the first frequency band maximally outputtable by the electronic device and a path loss of the signal in the first frequency band.

11 . The method of claim 10 , wherein the determining of the quality of the signal to be received via the first frequency band further comprises:
determining a path loss of the signal received via the second frequency band, based on an output strength of the signal via the second frequency and a quality of the signal received via the second frequency band, based on the TPC information; and determining the path loss of the signal in the first frequency band, based on the first frequency band, the second frequency band, and the determined path loss.

12 . The method of claim 9 , further comprising:
refraining a communication circuitry of the electronic device from scanning the non-PSC of the first frequency band based at least part on that the quality of the signal to be received via the first frequency band does not satisfy the specified condition.

13 . The method of claim 9 , further comprising:
displaying an indicator indicating that scanning of the channel is not performed, on a display, upon determining not to perform scanning of the channel.

14 . The method of claim 9 , further comprising:
obtaining the RNR information and/or the TPC information through an operation of scanning the channel via the second frequency band.

15 . The method of claim 9 , wherein the first frequency band is a 6 GHZ band, and the second frequency band is a 5 GHz band or a 2.4 GHz band.

16 . An electronic device comprising:
communication circuitry configured to perform short-range wireless communication via a first frequency band and/or a second frequency band lower than the first frequency band; and at least one processor; memory storing instructions, wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to: receive, via the second frequency band, a signal including reduced neighbor report (RNR) information and transmit power control (TPC) information from an external electronic device, identify whether the RNR information includes information on a non-preferred scanning channel (non-PSC) of the first frequency band; in a case that the RNR information includes the information on the non-PSC of the first frequency band:
