Abstract: A method for repetitive transmission of a transport block, performed by a first communication node, may comprise generating a first modulation symbol by performing a modulation operation on a first bit sequence of the transport block; generating a second bit sequence by changing an arrangement order of bits included in the first bit sequence according to a preconfigured rule; generating a second modulation symbol by performing the modulation operation on the second bit sequence; and transmitting, to a second communication node, the first modulation symbol and the second modulation symbol on different data channels.

Abstract: A feedback signal transmission method performed by a first terminal in a communication system may comprise receiving first configuration information for a first PUCCH format for feedback for a unicast transmission scheme and a second PUCCH format for feedback for a multicast transmission scheme from a first base station; receiving first DCI for scheduling first downlink data; receiving the first downlink data; and performing a feedback operation for the first down data, wherein the receiving of the first DCI and the performing of the feedback operation for the first downlink data are performed differently for a case when the first downlink data is downlink data transmitted according to the unicast transmission scheme and a case when the first downlink data is downlink data transmitted according to the multicast transmission scheme.

Abstract: An operation method of a terminal in a communication system may comprise: performing a monitoring operation to receive BWP configuration information for common downlink communication; in response to receiving the BWP configuration information from the base station, configuring a common frequency region for the common downlink communication based on the BWP configuration information; receiving DCI including scheduling information of the common downlink communication from the base station; and performing the common downlink communication with the base station in the common frequency region by using a frequency resource indicated by the scheduling information, wherein the common downlink communication is communication between the base station and a plurality of terminals including the terminal.

Abstract: An operation method of a terminal in a communication system may comprise: receiving, from a base station, a higher layer message including information indicating that first DCI including a HARQ feedback enabled/disabled indicator is configured; receiving the first DCI from the base station; receiving first downlink data from the base station based on first scheduling information included in the first DCI; and determining whether to transmit a first HARQ response for the first downlink data based on the HARQ feedback enabled/disabled indicator included in the first DCI.
