Problems solved by technology

[0007] In particular, if intelligent machine-to-machine (M2M, machine-to-machine) communication utilizing things is even expected to provide a new mobile market in addition to communication between people, (such as communication between people and things, things Communications between devices, etc.) are also popularized, it is expected that the traffic sent to the base station (BS, base station) or evolved node B (eNB, evolved nodeB) will increase sharply, so it may be difficult to handle the traffic

Abstract

The invention discloses a method and apparatus for transmitting and receiving a signal in a communication system supporting device todevice scheme. The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting a device to device (D2D) discovery signal by a user equipment (UE) in a communication system supporting a D2D scheme is provided. The method includes determining transmission power for D2D discovery signal transmission, and transmitting a D2D discovery signal using the transmission power, wherein the transmission power is determined by considering a cell at which the D2D discovery signal is transmitted.

Description

technical field [0001] The present disclosure relates to methods and apparatuses for transmitting and receiving signals in a communication system supporting a device to device (D2D) scheme. More particularly, the present disclosure relates to methods and apparatuses for transmitting and receiving D2D signals in a communication system supporting a D2D scheme. Background technique [0002] In order to meet the demands of increased wireless data traffic since deployment of fourth generation (4G) communication systems, efforts have been made to develop improved 5th generation (5G) or pre-5G communication systems. Therefore, the 5G or pre-5G communication system is also called "super 4G network" or "post-long-term evolution (LTE, long-term evolution) system". [0003] It is believed that 5G communication systems will be implemented in millimeter wave (mmWave) frequency bands (eg, 60GHz frequency band) in order to achieve higher data rates. In order to reduce the propagation los...
