    Abstract: Disclosed are a method and an apparatus for transmitting and receiving channel state information in a wireless communication system. A method for transmitting channel state information (CSI) according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information related to the CSI from a base station, wherein the configuration information includes information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station on the basis of the configuration information and the CSI-RS. The CSI may include a first CSI set based on a single CSI resource in the CSI-RS resource set and/or a second CSI set based on a CSI-RS resource combination in the CSI-RS resource set, and the number of CSI processing units (CPUs) required for calculation of the second CSI set and the number of CPUs required for calculation of the first CSI set may be individually determined.

    Abstract: Methods and apparatuses for performing communication in a wireless communication system. A user equipment (UE) receives first satellite ephemeris information related to a first satellite and information related to a first validity duration corresponding to the first satellite from a base station; and restarts a first validity timer, based on second satellite ephemeris information related to the first satellite being received from the base station while the first validity timer having the first validity duration is running. The UE obtains a first TA for the first satellite based on the first satellite ephemeris information before the first validity timer restarts, expires, or stops after starting based on the first validity duration, and the UE obtains a second TA for the first satellite based on the second satellite ephemeris information before the first validity timer expires or stops after restarting based on a second validity duration.

    Abstract: The present disclosure relates to a method, performed by a user equipment (UE), for reporting channel state information (CSI) in a wireless communication system and an apparatus therefor. According to the present disclosure, the UE receives a channel state information reference signal (CSI-RS) from a base station through a multiple antenna port; and reports the CSI to the base station, wherein the CSI includes a precoding matrix indicator for a codebook generated by linear combination, wherein the codebook is generated based on a specific parameter set, and wherein the specific parameter set is differently set/applied based on at least one of a rank value or at least one layer index of a specific rank.
