Abstract

An electronic device comprises: a communication circuit configured to transmit and/or receive data to and/or from a first external electronic device connected through short-range wireless communication; and a processor. The processor may be configured to: receive, from the first external electronic device, target wake time (TWT) parameters of the first external electronic device; transmit a request signal for information related to TWT parameters of a second external electronic device belonging to a basic service set (BSS) different from a BSS including the electronic device and the first external electronic device; determine whether to configure TWT parameters of the first external electronic device based on whether a response signal corresponding to the request signal is received; and configure the TWT parameters of the first external electronic device based on TWT parameters.

First claim

The invention claimed is:

1 . An electronic device comprising:
a communication circuit configured to transmit and/or receive data to and/or from a first external electronic device connected through short-range wireless communication; and at least one processor, comprising processing circuitry, operably connected to the communication circuit, wherein the at least one processor is configured, individually and/or collectively, to:
receive, from the first external electronic device connected to the electronic device, target wake time (TWT) parameters of the first external electronic device;
identify a channel utilization of a channel established between the electronic device and the first external electronic device while performing the short-range wireless communication with the first external electronic device; and
based on the identification that the channel utilization is greater than or equal to a specified value, control the communication circuit to transmit, to a second external electronic device, a request signal for information related to TWT parameters of the second external electronic device, wherein the second external electronic device belongs to a basic service set (BSS) different from a BSS including the electronic device and the first external electronic device;
receive, from the second external electronic device, a response signal including TWT parameters of the second external electronic device; and
configure TWT duration included in TWT parameters of the first external electronic device based on the TWT parameters of the second external electronic device.

2 . The electronic device of claim 1 , wherein the at least one processor is configured individually and/or collectively to control the communication circuit to transmit the request signal for information related to TWT parameters including information for the second external electronic device to determine whether to transmit the response signal.

3 . The electronic device of claim 2 , wherein a signal for determining whether to transmit the response signal includes information for calculating a maximum value of a TWT interval and/or information for calculating a minimum value of a TWT duration.

4 . The electronic device of claim 3 , wherein the at least one processor is configured individually and/or collectively to determine to configure the TWT parameters of the first external electronic device based on a response signal received from the second external electronic device performing a TWT operation using a TWT interval smaller than the maximum value and/or a TWT duration greater than the minimum value.

5 . The electronic device of claim 1 , wherein the configured TWT parameters of the first external electronic device enables a length of a duration in which a TWT duration of the first external electronic device and a TWT duration of the second external electronic device is overlapped to be less than a specified value.

6 . The electronic device of claim 1 , wherein the at least one processor is configured individually and/or collectively to change a channel between the electronic device and the first external electronic device in response to determining that changing TWT parameters of the first external electronic device is not enabled.

7 . The electronic device of claim 1 , wherein a frequency band of a channel established between the electronic device and the first external electronic device is identical to a frequency band of a channel used by the second external electronic device.

8 . The electronic device of claim 1 , wherein:
the at least one processor is configured individually and/or collectively to control the communication circuit to transmit a request signal for information related to TWT parameters of the second external electronic device; and the request signal includes the TWT parameters of the first external electronic device.

9 . An operation method of an electronic device, the method comprising:
receiving, from a first external electronic device connected to the electronic device, target wake time (TWT) parameters of the first external electronic device; identifying a channel utilization of a channel established between the electronic device and the first external electronic device while performing the short-range wireless communication with the first external electronic device; based on identification that the channel utilization is greater than or equal to a specified value, transmitting a request signal for information related to TWT parameters of a second external electronic device, wherein the second external electronic device belongs to a basic service set (BSS) different from a BSS including the electronic device and the first external electronic device; receiving, from the second external electronic device, a response signal including TWT parameters of the second external electronic device; and configuring TWT duration included in TWT parameters of the first external electronic device based on the TWT parameters of the second external electronic device.

10 . The operation method of claim 9 , wherein transmitting a request signal for information related to TWT parameters comprises transmitting the request signal for information related to TWT parameters including information for the second external electronic device to determine whether to transmit the response signal.

11 . The operation method of claim 10 , wherein a signal for determining whether to transmit the response signal includes information for calculating a maximum value of a TWT interval and/or information for calculating a minimum value of a TWT duration.

12 . The operation method of claim 11 , wherein configuring the TWT duration of the first external electronic device comprises determining to change the TWT parameters of the first external electronic device based on a response signal received from the second external electronic device performing a TWT operation using a TWT interval smaller than the maximum value and/or a TWT duration greater than the minimum value.

13 . The operation method of claim 9 , wherein configuring the TWT duration of the first external electronic device comprises configuring the TWT parameters of the first external electronic device so that an overlapping section between a TWT duration of the second external electronic device and a TWT duration of the first external electronic device is less than or equal to a specified size.

14 . The operation method of claim 9 , further comprising changing a channel between the electronic device and the first external electronic device in response to determining that it is not possible to change the TWT parameters of the first external electronic device so that the overlapping section between a TWT duration of the second external electronic device and a TWT duration of the first external electronic device is less than or equal to the specified size.
