Abstract: The present disclosure relates to 5th generation (5G) or pre-5G communication systems supporting higher data transmission rates than 4th generation communication systems (e.g., Long-Term Evolution). A method to be performed by a repeater device includes receiving, from a base station in the wireless communication system, control information including configuration information indicating a repeater index list, receiving, from the base station, a downlink signal, identifying whether an index of the downlink signal is included in the repeater index list, based on identifying that the index of the downlink signal is included in the repeater index list, amplifying the downlink signal, and transmitting a repeater beamforming signal that is generated by applying a beamforming weight to the amplified downlink signal, and, based on identifying that the index of the downlink signal is not included in the repeater index list, amplifying the downlink signal and transmitting the amplified downlink signal.

Abstract: Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and a MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present invention relates to a method for guaranteeing quality of service in a wireless communication system. More particularly, a method of a base station according to an embodiment of the present invention comprises the steps of: identifying at least one non-Guaranteed bit rate (GBR) bearer configured for an arbitrary communication device; determining whether to guarantee a specific bit rate to the non-GBR bearer, on the basis of at least one of QoS class identifier (QCI) information, allocation and retention priority (ARP) information, and subscriber profile identifier (SPID), which are received from a core network node for the non-GBR bearer; and performing scheduling for the non-GBR bearer on the basis of the determination.
