Method and apparatus for partial beam failure recovery in a wireless communications system

A base station (BS), comprising:

• a transceiver configured to:
• transmit first information on reference signal (RS) sets including (i) a first RS set for detecting a first beam failure and (ii) a second RS set for detecting a second beam failure, and
• transmit a medium access control control element (MAC CE) message indicating one or more RS resources in at least one of the first RS set or the second RS set,
• wherein the first beam failure or the second beam failure is associated with the one or more RS resource.

A method performed by a user equipment (UE), the method comprising:

• identifying first information on reference signal (RS) sets including (i) a first RS set for detecting a first beam failure and (ii) a second RS set for detecting a second beam failure;
• receiving a medium access control control element (MAC CE) message indicating one or more RS resources in at least one of the first RS set and the second RS set;
• and
• detecting at least one of the first beam failure or the second beam failure based on the one or more RS resources.
