Abstract: The disclosure relates to an improved wireless local area network (LAN) system. A method and device for transmission opportunity (TXOP) sharing that considers dynamic power save (DPS) in an improved wireless LAN system are provided. Specifically, the disclosure provides a method performed by a first access point (AP) in a wireless LAN system, the method including transmitting, to a second AP, a first frame for notifying of sharing of a transmission opportunity (TXOP), receiving, from the second AP, a second frame for responding to the first frame, the second frame including information on a dynamic power save (DPS) mode related to the TXOP and information on a required TXOP length, and transmitting, to the second AP, a third frame including information on a TXOP to be shared with the second AP.

Abstract: A method performed by an access point in a wireless local area network (WLAN) system is provided. The method includes receiving, from a station, a first frame on a first link in a lower capability mode (LCM) among power save modes, determining, based on the first frame, whether to switch to a higher capability mode (HCM) among the power save modes and whether to switch a link for receiving data based on the first frame, and transmitting, to the station, a response frame for the first frame on the first link, wherein in case that it is determined to switch the power save mode to the HCM and to switch the link for receiving the data to a second link, the response frame includes information indicating that the data is to be transmitted on the second link.

Abstract: A method and an apparatus for channel access in a wireless LAN (WLAN) system are provided. In a wireless local area network (WLAN) system, the method performed by an access point (AP) includes identifying, by the AP, a first overlapping basic service set (OBSS) transmission opportunity (TXOP) including a primary channel; performing, by the AP, non-primary channel access (NPCA) based on identifying the first OBSS TXOP; identifying, by the AP, truncation of the first OBSS TXOP; and terminating, by the AP, the NPCA based on identifying the truncation of the first OBSS TXOP.

Abstract: The disclosure relates to a wireless LAN system. An embodiment of the disclosure provides a method and a device for configuring an STA capable of performing NPCA so as to efficiently perform non-primary channel access (NPCA). The method of an electronic device comprises: obtaining a non-primary channel access (NPCA) information element; transmitting a frame including the NPCA information element; and performing an NPCA with a station (STA) associated with the electronic device on a non-primary channel (NPCH), wherein the NPCA information element comprises basic NPCA information and NPCA-enabling condition information.

Abstract: An apparatus and a method for treating garments are provided. A method, performed by a garment treatment apparatus, of controlling an operation of the garment treatment apparatus includes: establishing wireless communication with a monitoring device placed inside a drum of the garment treatment apparatus; rotating the drum; receiving movement information associated with movement of the monitoring device from the monitoring device during the rotation of the drum; and controlling the rotation of the drum based on the received movement information.

Abstract: Disclosed is an electronic device and a method for controlling the electronic device. The electronic device includes: a microphone, a communication interface, a memory for storing at least one instruction, and a processor configured to execute the at least one instruction to: determine whether a user is present around the electronic device based on voice data of the user obtained via the microphone, determine a device group including the electronic device and at least one other electronic device present around the electronic device, identify at least one device from the device group as a hub device to perform a voice recognition, and based on identifying the electronic device as the hub device, obtain, through the communication interface, a voice data of the user from one or more of the at least one other electronic device, and perform the voice recognition.

Abstract: Disclosed are an electronic apparatus and a controlling method thereof.

Abstract: A stylus pen and a controlling method thereof are provided. A stylus pen housed in and withdrawn from a terminal device includes a user inputter configured to receive a contact command of a user, a microphone configured to receive a voice command of a user, a communicator configured to transmit the received voice command to the terminal device, and a processor configured to control the user inputter, the microphone, and the communicator, and the processor may, based on the stylus pen being withdrawn from the terminal device, and a first contact command being received through the user inputter, activate the microphone which is in a deactivated state to convert the stylus pen to a main voice input device.
