Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th (4G) communication system such as long term evolution (LTE). According to a various embodiments of the present disclosure, a base station in a wireless communication system may comprise the steps of: acquiring, in a first time interval, channel information of a downlink channel with a terminal; on the basis of the unscented Kalman filter, acquiring current channel state information from previous state information and the channel information; and generating, from the current channel state information, predicted channel information in a second time interval.

Abstract: A method and an apparatus of a coordinator forming a coordinated communication system for enhancing cell edge terminal throughput are provided. The method includes receiving information on Sound Reference Signal (SRS) reception power at a terminal for respective cells of a scheduler belonging to the coordinator from the scheduler, generating terminal distinction information for indicating whether a terminal is a cell edge terminal based on the SRS reception power information or Signal to Interference plus Noise Ratio (SINR) estimated from the SRS reception power information, generating interference relationship information between terminals and cells based on the SRS reception power information or estimated SINR, and transmitting the terminal distinction information and interference relationship information to the scheduler.

Abstract: A method for a serving base station determining a modulation and coding selection (MCS) of a terminal in a wireless communication system, according to the present invention, comprises the steps of: determining uplink interference from neighboring cells; determining a signal-to-interference plus noise ratio (SINR) based on a reply signal indicating whether data transmitted by the terminal is successfully received and the interference information; and determining the MCS based on the SINR information and the reply signal. According to the present invention, an MCS level can be determined according to a channel status of a receiver by accurately determining interference from nearby cells, thereby improving data transmission/reception efficiency.
