Method and device for reference signal linkage-based downlink transmission/reception in wireless communication system

An apparatus comprising:

• at least one transceiver;
• and
• at least one processor coupled with the at least one transceiver,
• wherein the at least one processor is configured to:
• receive configuration information for a mapping between a first resource for uplink transmission and at least one second resource for downlink reception;
• receive information for a spatial parameter for the first resource,
• wherein the information includes reference signal information for a spatial relation for the first resource;
• and
• determine a spatial parameter for the at least one second resource based on the mapping and the reference signal information.

A method comprising:

• transmitting configuration information for a mapping between a first resource for uplink transmission and at least one second resource for downlink reception;
• and
• transmitting information for a spatial parameter for the first resource,
• wherein the information includes reference signal information for a spatial relation for the first resource, and
• wherein a spatial parameter for the at least one second resource is based on the mapping and the reference signal information.

A non-transitory computer-readable medium storing at least one computer program comprising instructions that, when executed by at least one processor, cause the at least one processor to:

• receive configuration information for a mapping between a first resource for uplink transmission and at least one second resource for downlink reception;
• receive information for a spatial parameter for the first resource,
• wherein the information includes reference signal information for a spatial relation for the first resource;
• and
• determine a spatial parameter for the at least one second resource based on the mapping and the reference signal information.
