Abstract: Methods, a Base Station (BS), and a User Equipment (UE) in a wireless communication system for transmitting and receiving control information are provided. The method for transmitting control information by a BS in a wireless communication system includes receiving information related to a signal transmitted by a second BS that the second BS which is a neighboring BS of the first BS, determining whether a second UE using an identical resource to that used by a first UE included in a cell of the first BS exists within a cell of the second BS based on the received information, when the second UE exists, generating control information for controlling a signal transmitted to the second UE by the second BS based on the received information, and transmitting the generated control information to the first UE through a control channel.

Abstract: Methods and apparatuses are provided for operating a first terminal. A motion of the first terminal is determined by using sensor data from at least one sensor of the first terminal. A prediction for a channel quality between the first terminal and a second terminal is performed based on the determined motion of the first terminal. At least one first time duration in which the predicted channel quality is greater than or equal to a threshold value and at least one second time duration in which the predicted channel quality is less than the threshold value are determined. Data is transmitted to the second terminal via a first transmission power, where the first transmission power is set for the at least one first time duration.

Abstract: A method for operating a User Equipment (UE) is provided to minimize performance degradation due to a difference between a transmit power for D2B communication and a transmit power for Device to Device (D2D) communication. The method includes transmitting a signal for D2B communication to a Base Station (BS) and a signal for D2D communication to another UE in a first time period, and configuration for the D2D communication, when it is determined there is a difference between a transmit power for the D2B communication and a transmit power for the D2D communication.
