Method and device for beam management in wireless communication system

A user equipment (UE) comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operably connectable to the one or more processors and storing instructions that configure the one or more processors to perform operations based on being executed by the one or more processors,
• wherein the operations comprise:
• receiving configuration information including information related to at least one downlink reference signal (DL RS);
• receiving the at least one DL RS;
• and
• transmitting information related to a UE preference determined based on a measurement for the at least one DL RS,
• wherein the at least one DL RS is based on a plurality of DL RSs related to at least one of i) beams of a first set and/or ii) beams of a second set related to the first set, and
• wherein the information related to the UE preference is related to at least one of i) a configuration of the second set and/or ii) a property related to a beam of the second set.

A base station comprising:

• one or more transceivers;
• one or more processors;
• and
• one or more memories operably connectable to the one or more processors and storing instructions that configure the one or more processors to perform operations based on being executed by the one or more processors,
• wherein the operations comprise:
• transmitting configuration information including information related to at least one downlink reference signal (DL RS);
• transmitting the at least one DL RS;
• and
• receiving information related to a user equipment (UE) preference determined based on a measurement for the at least one DL RS,
• wherein the at least one DL RS is based on a plurality of DL RSs related to at least one of i) beams of a first set and/or ii) beams of a second set related to the first set, and
• wherein the information related to the UE preference is related to at least one of i) a configuration of the second set and/or ii) a property related to a beam of the second set.
