Abstract: A mode switching method and apparatus of a terminal including a camera for acquiring motion information of a user and a plurality of operation modes for power management is provided. The mode switching method includes transitioning, when a motion of a first pattern is detected by the camera, the terminal from an active mode to a standby mode, transitioning, when a motion of a second pattern is detected by the camera, the terminal from the standby mode to an inactive mode, and transitioning, when a first mode switching input is detected in the inactive mode, from the inactive mode to the active mode, wherein the camera acquires the motion information of the user in at least one of the active mode and the standby mode.

Abstract: A method and an apparatus for detecting signals in a cellular system are provided. The method includes estimating power of a dominant interference cell and detecting a signal by reducing a detection performance degradation caused by an interference signal of the dominant interference cell. The dominant interference cell includes a cell, other than a serving cell, causing an interference.

Abstract: A method for selecting a Multiple-Input Multiple-Output (MIMO) mode based on energy efficiency and selecting an antenna subset to be used in a communication, in a wireless communication system using a multi-user massive multi-antenna is provided. The method selects an antenna subset capable of minimizing transmission power without using all antennas, based on power consumed by an Radio Frequency (RF) circuit as well as the transmission power. The method further includes selecting a mobile station to which the signal is to be transmitted, selecting a multi-antenna technique based on power consumption of all antennas, selecting an antenna subset to transmit the signal to the mobile station among all the antennas, and transmitting the signal to the mobile station by using the antenna subset.
