Abstract: A method and apparatus for reducing power consumption in a mobile device of a wireless communication system when discovering a central node is provided. The method for operating of a terminal for discovering at least one central node in a wireless communication system includes: generating a probe request signal and transmitting the probe request signal to at least one central node; after transmitting the probe request signal, switching from a normal mode to a low power mode and driving the terminal in the low power mode; in response to a mode switch instruction signal being received from the central node, switching the terminal from the low power mode to the normal mode; and receiving a probe response signal to the probe request signal from the central node in the normal mode.

Abstract: The present disclosure relates to 5th generation (5G) or pre-5G communication systems to support a higher data rate than the long term evolution (LTE) or other 4th generation (4G) communication systems. A method for transmitting data in a communication system is provided. The method includes identifying, by a station (STA) communicating with a first access point (AP), a resource for performing communication with a second AP positioned adjacent to the STA based on information regarding a capability of the STA, performing the communication with the second AP using the resource, and transmitting data obtained by performing the communication with the second AP to the first AP. The information regarding the capability includes one of information regarding multiple antennas available on the STA, information regarding a base-band processing unit including the multiple antennas, or information regarding a modem including the multiple antennas and the base-band processing unit.
