Method and Device in Node for Wireless Communication

A UE for wireless communication, comprising:

• a receiver for receiving wireless communication signals;
• a transmitter for transmitting wireless communication signals;
• a processor for executing computer-executable instructions;
• and
• a non-transitory machine-readable storage medium, coupled to the processor, for storing the computer-executable instructions, wherein the computer-executable instructions instruct the processor to:
• receive, via the receiver, a Radio Resource Control (RRC) signaling comprising L reference signal resource set(s) and Q second-type bit field(s), each of the L and the Q being a positive integer, each of the Q second-type bit field(s) for indicating one power offset, each of the Q second-type bit field(s) corresponding to one of a plurality of K1 indexes related to the L reference signal resource set(s), the Q second-type bit field(s) include(s) only one second-type bit field corresponding to a first index of the K1 indexes;
• receive, via the receiver, a physical layer (PHY) signaling comprising a first bit field for determining a first reference signal resource set associated to the plurality of K1 indexes;
• and
• transmit a first radio signal at a first power value, the first power value being only related to power offsets indicated by all second-type bit fields among the Q second-type bit field(s) that correspond to the first index, the first index being one of the K1 indexes, the first radio signal being Quasi Co-located (QCLed) with one of the L reference signal resource set(s), the first reference signal resource set being one of the L reference signal resource set(s) that corresponds to the first radio signal.
