Method and apparatus for multiple physical shared channel scheduling in wireless communication systems

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a processor operably connected to the transceiver and configured to:
• receive, from a base station, a radio resource control (RRC) message including scheduling information related to a plurality of physical downlink shared channels (PDSCHs),
• receive, from the base station, downlink control information (DCI),
• identify whether the DCI is related to a secondary cell (SCell) dormancy indication,
• identify, based on the scheduling information related to the plurality of PDSCHs, a number of bits of a new data indicator (NDI) field and a number of bits of a redundancy version (RV) field included in the DCI,
• identify a bitmap of the SCell dormancy indication included in the DCI based on the number of bits of the NDI field and the number of bits of the RV field, and
• identify an active bandwidth part (BWP) for the SCell configured in the terminal based on the identified bitmap.

A method of a base station in a wireless communication system, the method comprising:

• transmitting, to a terminal, a radio resource control (RRC) message including scheduling information related to a plurality of physical downlink shared channels (PDSCHs);
• and
• transmitting, to the terminal, downlink control information (DCI),
• wherein the DCI is related to a secondary cell (SCell) dormancy indication,
• wherein, based on the scheduling information related to the plurality of PDSCHs, a number of bits of a new data indicator (NDI) field and a number of bits of a redundancy version (RV) field included in the DCI is configured,
• wherein a bitmap of the SCell dormancy indication included in the DCI is configured based on the number of bits of the NDI field and the number of bits of the RV field, and
• wherein an active bandwidth part (BWP) for the SCell configured in the terminal is configured based on the identified bitmap.
