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:
Disclosed is a method by which a base station (BS) updates an autoencoder (AE) for channel state information (CSI) feedback in a wireless communication system, including transmitting, to a user equipment (UE), a data collect instruction message instructing to collect data before compression corresponding to compressed data, receiving data before the compression from the UE, and updating an AE, based on the received data before compression.

A method and corresponding apparatus include extracting a movement trajectory feature of an object from an input video. The method and corresponding apparatus also include coding the extracted movement trajectory feature, and determining a type of a movement of the object based on the coded movement trajectory feature.
Abstract:
A method of preprocessing an image including biological information is disclosed, in which an image preprocessor may set an edge line in an input image including biological information, calculate an energy value corresponding to the edge line, and adaptively crop the input image based on the energy value.
Abstract:
A fingerprint recognition method includes receiving an input partial image corresponding to a partial image of a fingerprint of a first user; partitioning the input partial image into a plurality of blocks; performing a comparison operation based on the plurality of blocks and the enrolled partial images corresponding to partial images of an enrolled fingerprint; and recognizing the fingerprint of the first user based on a result of the comparison operation.
Abstract:
A liveness testing apparatus includes a testing circuit. The testing circuit is configured to test a liveness of an object included in a received input image based on whether an image of the object has a characteristic indicative of a flat surface or a characteristic indicative of a three-dimensional (3D) structure.
Abstract:
A user authentication method includes receiving a first input image including information on a first modality; receiving a second input image including information on a second modality; determining at least one first score by processing the first input image based on at least one first classifier, the at least one first classifier being based on the first modality; determining at least one second score by processing the second input image based on at least one second classifier, the at least one second classifier being based on the second modality; and authenticating a user based on the at least one first score, the at least one second score, a first fusion parameter of the at least one first classifier, and a second fusion parameter of the at least one second classifier.
Abstract:
A method for updating biometric authentication data authenticates an input image using an enrollment database (DB) over a first length of time, the authentication including generating information for authenticating the input image, and updates the enrollment DB based on the first length time and the information for authenticating the input image.
Abstract:
The present disclosure relates to a fifth generation (5G) communication system or a sixth generation (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 wireless communication system may include transmitting, to a base station, an artificial intelligence (AI)-based channel state information (CSI) feedback mode supported by an AI model of the UE and capability information corresponding to the CSI feedback mode, the AI-based CSI feedback mode including at least one of an AI-based channel prediction mode or an AI-based CSI compression mode, receiving, from the base station, an indicator indicating the CSI feedback mode performed by the UE and configuration information corresponding to the CSI feedback mode performed by the UE, generating CSI, based on the received configuration information and a CSI-reference signal (CSI-RS), and transmitting the generated CSI to the base station.
