Method and device for transmitting and receiving group-common information in wireless communication system

A user equipment (UE) of receiving group common information in a wireless communication system, the UE 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 network, configuration information on at least one channel state information-reference signal (CSI-RS) resource set for a tracking reference signal (TRS);
• receive, from the network, group common downlink control information (DCI) based on a group common identifier and a specific CSI-RS resource set among the at least one CSI-RS resource set;
• and
• receive, from the network, a group common physical downlink shared channel (PDSCH) scheduled by the group common DCI,
• wherein the at least one CSI-RS resource set is configured for at least one of one or more group common identifiers or one or more cell groups including the group common identifier.

A base station of transmitting group common information in a wireless communication system, the base station 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:
• transmit, to a user equipment (UE), configuration information on at least one channel state information-reference signal (CSI-RS) resource set for a tracking reference signal (TRS);
• transmit, to the UE, group common downlink control information (DCI) based on a group common identifier and a specific CSI-RS resource set among the at least one CSI-RS resource set;
• and
• transmit, to the UE, a group common physical downlink shared channel (PDSCH) scheduled by the group common DCI,
• wherein the at least one CSI-RS resource set is configured for at least one of one or more group common identifiers or one or more cell groups including the group common identifier.
