According to various embodiments, an electronic device comprising a processor, a communication module circuitry operatively connected to the processor, and an output device operatively connected to the processor may be provided. The processor may be configured to activate a first channel for providing a push-to-talk (PTT) service and deactivate a second channel for providing the PTT service in a state in which the first channel and the second channel are generated, transmit a first message associated with the first channel including information indicating that the first channel is activated, through the communication module circuitry to a PTT server configured to provide the PTT service, transmit a second message associated with the second channel including information indicating that the channel is deactivated, through the communication module circuitry to the PTT server, output first media data associated with the first channel using first part of the output device.

Electronic device and server providing push-to-talk service and method for operating the same

An example electronic device may include at least one processor and a communication device. The at least one processor may be configured to identify a call generating request for first user identification information defined in a first metaverse service; establish, through the communication device, a media session between the electronic device and a first server corresponding to the first metaverse service, based on the call generating request; receive, through the communication device, first data for representing a virtual space associated with an avatar corresponding to the first user identification information, using the media session; provide first content representing the virtual space associated with the avatar using the received first data; transmit, through the communication device, a message including user manipulation information input corresponding to the content; receive, through the communication device, second data for representing a virtual space associated with the avatar set based on the user manipulation information, using the media session; and provide second content representing the virtual space associated with the avatar using the received second data.

Electronic device performing call with user of metaverse and method for operating the same

A method of communication based on a receive chain control, performed by a receiver, in a wireless local area network is provided. The method includes: receiving a frame from a transmitter, the frame indicating a multi receive chain operation, activating at least one receive chain, each receive chain processing a received signal transmitted through each spatial stream, and receiving at least one data field from the transmitter through the at least one activated receive chain.

Method of communication based on controlling receive chain in wireless local area network and apparatus for the same

A wireless communication system includes at least one AP assigned with a unique MAC address and a shared virtual MAC address; and at least one mobile station to search the at least one AP, receive AP information from the retrieved AP, and perform a handoff, wherein the mobile station transmits query data to the shared virtual MAC address, receives response data from the AP, determines whether the AP exists on a predetermined channel, and when the AP exists on the channel, requests the AP having the shared virtual MAC address for AP information, and receives the AP information from the AP.
