Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting higher data rates. Disclosed is a method performed by a terminal in a wireless communication system, including receiving downlink control information (DCI) from a base station, identifying whether the DCI includes a dynamic waveform indicator, and in case that the DCI includes a dynamic waveform indicator, transmitting, to the base station, an uplink signal through a physical uplink shared channel (PUSCH) based on an uplink waveform indicated by the dynamic waveform indicator.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a UE in a wireless communication system is provided, which includes receiving, from a BS, configuration information associated with a UL, the configuration information including SRS resource set information including a first SRS resource set and a second SRS resource set, information indicating that at most two PT-RS ports are used for the UL, and information for a configuration of simultaneous transmission across multi-panel (STxMP); receiving, from the BS, DCI including association information between a PT-RS port and a DMRS port; and in case STxMP is configured, transmitting, based on the DCI, the PT-RS using a first PT-RS port and a second PT-RS port, according to the received configuration of the STxMP. The first PT-RS port is associated with at least one first DMRS port associated with the first SRS resource set, and the second PT-RS port is associated with at least one second DMRS port associated with the second SRS resource set.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from a base station, downlink control information (DCI) including a sounding reference signal resource set indicator (SRSI), two sounding reference signal resource indicator (SRI) fields, and two transmission precoding matrix indicator (TPMI) fields and transmitting, to the base station, a physical uplink shared channel (PUSCH) based on the DCI.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Specifically, the disclosure provides a method and a device for an uplink transmission procedure in consideration of simultaneous transmission via multiple panels. Methods and devices are provided in which first downlink control information (DCI) scheduling a first physical uplink shared channel (PUSCH) and second DCI scheduling a second PUSCH, are received. The first PUSCH and the second PUSCH are simultaneous transmissions across multi panels (STxMP). Third DCI is received that indicates a physical uplink control channel (PUCCH) that overlaps the first PUSCH and the second PUSCH. A PUSCH is identified, from among the first PUSCH and the second PUSCH, that is associated with a control resource set (CORESET) pool index for the third DCI. Uplink control information (UCI) is transmitted by multiplexing the UCI in the identified PUSCH.

Abstract: A fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate and a method performed by a user equipment (UE) in a communication system are provided. The method includes receiving, from a base station, information on a list of timing values associated with a physical downlink shared channel (PDSCH) to hybrid automatic repeat request acknowledgement (HARQ-ACK), receiving a PDSCH from the base station, determining a set of slot timing values based on the information, wherein an inapplicable value in the list of timing values is excluded from the set of slot timing values, transmitting, to the base station, a physical uplink control channel (PUCCH) including a Type-1 HARQ-ACK codebook associated with the PDSCH based on the set of slot timing values.

Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system to be provided for supporting higher data rates beyond 4th generation (4G) communication system such as long term evolution (LTE). The disclosure discloses, in a case that a terminal is configured with a time domain resource assignment (TDRA) including a plurality of start and length indication values (SLIVs) in a wireless communication system, a method for determining whether a downlink control information (DCI) format is used for a semi persistent scheduling (SPS) physical downlink shared channel (PDSCH) reception, a configured grant (CG) physical uplink shared channel (PUSCH) transmission, or a Scell dormancy indication transmission, and a selective SPS PDSCH reception method, a selective CG PUSCH transmission method, or a Scell dormancy application method according to the determination.
