Abstract: This disclosure relates to the 5th generation (5G) or pre-5G communication system for supporting a higher data rate after the 4th generation (4G) communication system such as Long Term Evolution (LTE). The method for operating the core network in a wireless communication system according to this disclosure comprises the processes of determining the content to store in the terminal based on the location information of the terminal, transmitting the content transmission command to the base station so as to transmit the content to the terminal in response to the determination, checking whether the terminal has entered the overload cell, and forming a D2D communication link between the terminal and another adjacent terminal when it is identified that the terminal has entered the overload cell.

Abstract: A method of reconstructing a downlink (DL) channel by a base station in a multiple-input-multiple-output (MIMO) communication system includes: estimating UL channel information on the basis of an uplink (UL) pilot signal received from a user equipment; extracting at least one key parameter among common parameters of the UL channel and the DL channel from the estimated UL channel information; estimating DL channel information using the UL channel information and the at least one key parameter; and reconstructing the DL channel by correcting an error between the estimated DL channel information and actual DL channel information.

Abstract: The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound can be a bipolar compound having a p-type moiety and an n-type moiety and has high energy level and proper energy bandgap for an emissive layer of the OLED. As the organic compound is applied into the emissive layer, the OLED can maximize its luminous properties as holes and electrons are recombined uniformly over the whole area in an emitting material layer (EML).
