    Abstract: A method performed by a terminal in a TDD communication system is provided. The method includes identifying that the terminal supports half-DuplexTDD-CA-SameSCS capability, identifying that directionalCollisionHandling is configured as ‘enabled’ for a set of serving cells among multiple serving cells including a first serving cell and a second serving cell, in case that the terminal is not capable of simultaneous reception and transmission on the first and second serving cells, identifying that the terminal is not configured to monitor a PDCCH for DCI format 2_0 on any of the multiple serving cells, identifying a first carrier of the first serving cell not configured for a PUCCH/PUSCH, and in case that a SRS on the first carrier and a physical channel on a second carrier of the second serving cell collide and directionalCollisionHandling is configured as ‘enabled’, applying a priority rule for the SRS transmission and then a procedure for the directional collision handling.

    Abstract: A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station, downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission, the DCI including information on a frequency resource for the PUSCH transmission and information indicating whether frequency hopping to be applied to the PUSCH transmission, and transmitting, to the base station, a PUSCH, based on precoding applied according to a predetermined resource unit based on the frequency resource for the PUSCH transmission, wherein, in case that the information indicating whether the frequency hopping to be applied for the PUSCH transmission indicates a value indicating that the frequency hopping is applied and the precoding is a wideband based precoding for the frequency resource for the PUSCH transmission, a first precoding is applied according to the predetermined resource unit configured to a size equal to the frequency resource for the PUSCH transmission, and for a frequency resource which is frequency hopped from the frequency resource for the PUSCH transmission, a second precoding different from the first precoding is applied according to the predetermined resource unit configured to a size equal to the frequency resource which is frequency hopped.

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. The present disclosure relates to a method performed by a terminal in a wireless communication system, wherein the method may comprise the steps of: receiving scheduling information, for the repeated transmission of a physical uplink shared channel (PUSCH), from a base station through a first signal; setting a time period, in which a signal for transmit power control (TPC) can be received and applied, for each of one or more PUSCHs scheduled through the first signal; and performing power control for the PUSCH transmissions corresponding to the set time periods on the basis of second signals received from a base station within the set time periods.
