    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method for efficiently selecting an optimal beam based on channel state information (CSI) in a 5G or 6G communication system is provided. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving a message including configuration information for a CSI report from a base station, receiving a plurality of CSI-reference signals (RSs) on different beams from the base station, generating a precoding matrix for the plurality of CSI-RSs, based on the configuration information, and transmitting the CSI report calculated based on the precoding matrix to the base station.

    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method performed by a user equipment (UE) in a 5G or 6G communication system is provided. The method includes receiving a message including configuration information for a conditional channel state information (CSI) report from a base station, receiving multiple CSI-reference signals (RSs) on different beams from the base station, selecting at least one CSI-RS satisfying at least one of a first condition or a second condition from the multiple CSI-RSs, based on the configuration information, and transmitting the conditional CSI report including information on the at least one CSI-RS to the base station.

    Abstract: Disclosed is a 5th generation (5G) or 6th generation (6G) communication system for supporting higher data rates after a 4th generation (4G) communication systems such as long term evolution (LTE). An operating method of a base station includes receiving, from a user equipment (UE), information about channel state information (CSI) measured based on a first CSI-reference signal (RS), determining, based on the information about the CSI, one autoencoder (AE), from among a plurality of AEs, transmitting, to the UE, information indicating an encoder included in the determined AE, transmitting a second CSI-RS to the UE, receiving, from the UE, CSI compressed based on CSI measured using the second CSI-RS and the indicated encoder, and performing reconstruction based on the compressed CSI and a decoder included in the determined AE.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method, performed by a base station, includes identifying configuration information for single carrier signal transmission, transmitting the single carrier signal transmission configuration information to a terminal, transmitting control information scheduling data transmission, and transmitting data to the terminal using a single carrier according to the single carrier signal transmission configuration information and the control information. The single carrier signal transmission configuration information comprises at least one of offset or comb information indicating a resource to which the terminal can be scheduled, frequency resource information of a bandwidth part, or sub-carrier spacing information.

    Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.
