Method and device for providing multicasting and broadcasting in communication system

A method performed by a base station in a communication system, the method comprising:

• transmitting, to a terminal, semi persistent scheduling (SPS) configuration information;
• identifying a set of SPS physical downlink shared channels (PDSCHs) to be activated;
• transmitting, to the terminal, downlink control information (DCI) for SPS activation;
• in a case that the set of SPS PDSCHs includes a plurality of SPS PDSCHs within one slot, performing transmission of an SPS PDSCH with a lowest index;
• and
• performing exclusion of the transmitted SPS PDSCH and a PDSCH that is overlapped with the transmitted SPS PDSCH from the set of SPS PDSCH,
• wherein in a case that there are two or more SPS PDSCHs with the lowest index and at least one bit of a field indicating a hybrid automatic repeat request (HARQ) process number included in the DCI is 1, an SPS PDSCH corresponding to the HARQ process number is transmitted.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station, semi persistent scheduling (SPS) configuration information,
• identify a set of SPS physical downlink shared channels (PDSCHs) based on the SPS configuration information and the SPS activation signal in a case that downlink control information (DCI) for SPS activation is detected,
• in a case that a plurality of SPS PDSCHs are included in the set of SPS PDSCHs within a slot, perform reception of an SPS PDSCH with a lowest index, and
• perform exclusion of the received SPS PDSCH and a PDSCH that is overlapped with the received SPS PDSCH from the set of SPS PDSCHs,
• wherein in a case that there are two or more SPS PDSCHs with the lowest index and at least one bit of a field indicating a hybrid automatic repeat request (HARQ) process number included in the DCI is 1, an SPS PDSCH corresponding to the HARQ process number is received.
