An apparatus and method are provided for receiving and transmitting signals/channels in a wireless communication system. A method performed by a terminal includes receiving configuration information on a first SS set and a second SS set, wherein the first SS set with a first index includes a first PDCCH candidate having a CCE AL 8 and a third PDCCH candidate having a CCE AL 16, and the second SS set with a second index includes a second PDCCH candidate having the CCE AL 8 and a fourth PDCCH candidate having the CCE AL 16; receiving a PDCCH based on the configuration information; determining a PUCCH resource based on an index of a first CCE for the PDCCH, wherein the index of the first CCE is determined based on a CCE AL of a PDCCH candidate associated with the second SS set with the second index which is smaller than the first index; and transmitting a PUCCH based on the PUCCH resource.

Method and apparatus for receiving physical downlink control channel and transmitting uplink control channel in wireless communication systems

A method performed by a terminal in a wireless communication system is provided. The method includes receiving, from a base station, first information indicating at least one DMRS type, via an RRC signaling, receiving, from the base station, second information indicating whether to activate an enhanced DMRS type corresponding to the at least one DMRS type, via a MAC-CE signaling, and in case that the second information indicates activation of the enhanced DMRS type, receiving, from the base station, a PDSCH or transmitting, to the base station, a PUSCH based on the enhanced DMRS type.

Method and apparatus of dynamic switching among types of transmission and reception for data and reference signal in wireless communication systems

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.
