    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 disclosure relates to a method and a device for transmitting and receiving a signal by a base station or a terminal in a wireless communication system. Specifically, a method performed by a first device in a wireless communication system includes deriving an amplitude scaling factor based on a comparison between amplitude distribution of a pilot signal corresponding to a first time resource domain and the amplitude distribution of a data signal corresponding to a second time resource domain; and transmitting, to a second device, a physical channel including the pilot signal and the data signal and the amplitude scaling factor, wherein the pilot signal is transmitted with a power determined based on the amplitude scaling factor, and power compensation for the data signal is based on the amplitude scaling factor.

    Abstract: The disclosure relates to a 5th generation (5G) communication system or a 6th generation (6G) communication system for supporting higher data rates beyond a 4th generation (4G) communication system, such as long term evolution (LTE). A method performed by a receiving node in a wireless communication system is provided. The method includes receiving first signals from a transmitting node, identifying compensation values in which distortion of the first signals is compensated on a time domain by using an artificial neural network trained by a designated scheme, and obtaining second signals of which the distortion is compensated based on the identified compensation values. The designated scheme may be determined by a size of a first resource block (RB) assigned to receive the first signals from the transmitting node.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. According to an embodiment, a method performed by a terminal in a wireless communication system may include transmitting, to a base station, training capability information of the terminal relating to artificial intelligence (AI) model training of an autoencoder configured to compress and reconstruct feedback information for a channel state information-reference signal (CSI-RS), receiving, from the base station, information on a training completion time point and decoder information determined based on the training capability information, generating a training dataset for the autoencoder, based on at least one received CSI-RS, training the autoencoder, based on the decoder information, the information on the training completion time point, and the generated training dataset, and transmitting training result information of the autoencoder to the base station.

    Abstract: The disclosure relates to a 5th generation (5G) communication system or a 6th generation (6G) communication system for supporting higher data rates beyond a 4th generation (4G) communication system, such as long term evolution (LTE). A method of a base station (BS) for sleep mode control is provided. The method includes transmitting scheduled downlink (DL) data to a user equipment (UE), detecting one or more consecutive discontinuous transmissions (DTX) at feedback timing corresponding to the DL data, transmitting downlink control information (DCI) including a wake-up confirming message (WCM) to the UE in response to the detection of the consecutive DTX, and determining that the UE is in wake-up mode based on reception of an acknowledgment (ACK) corresponding to the WCM from the UE.
