Method and device for transmitting/receiving group common pdsch in wireless communication system

A terminal of receiving a group common PDSCH (physical downlink shared channel) in a wireless communication system, the terminal comprising:

• at least one transceiver for transmitting and receiving a wireless signal;
• and
• at least one processor for controlling the at least one transceiver,
• wherein the at least one processor configured to:
• receive, from a base station, N (N is a natural number) reference signals;
• receive, from the base station, one or more downlink semi-persistent scheduling (SPS) configurations for group common transmission;
• and
• receive, from the base station, M (M is a natural number) group common PDSCHs scheduled using the one or more SPS configurations,
• wherein for assuming a quasi co-location (QCL) relationship for receiving the M group common PDSCHs, different group common PDSCHs in the M group common PDSCHs are mapped to different reference signals in the N reference signals.

At least one non-transitory computer-readable medium storing at least one instruction, wherein the at least one instruction executable by at least one processor controls a device of receiving a group common PDSCH (physical downlink shared channel) to:

• receive, from a base station, N (N is a natural number) reference signals;
• receive, from the base station, one or more downlink semi-persistent scheduling (SPS) configurations for group common transmission;
• and
• receive, from the base station, M (M is a natural number) group common PDSCHs scheduled using the one or more SPS configurations,
• wherein for assuming a quasi co-location (QCL) relationship for receiving the M group common PDSCHs, different group common PDSCHs in the M group common PDSCHs are mapped to different reference signals in the N reference signals.

A processing apparatus configured to control a terminal of receiving a group common PDSCH (physical downlink shared channel) in a wireless communication system, the processing apparatus comprising:

• at least one processor;
• and
• at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
• receiving, from a base station, N (N is a natural number) reference signals;
• receiving, from the base station, one or more downlink semi-persistent scheduling (SPS) configurations for group common transmission;
• and
• receiving, from the base station, M (M is a natural number) group common PDSCHs scheduled using the one or more SPS configurations,
• wherein for assuming a quasi co-location (QCL) relationship for receiving the M group common PDSCHs, different group common PDSCHs in the M group common PDSCHs are mapped to different reference signals in the N reference signals.
