1. A method for a User Equipment (UE) in a wireless communication system, comprising:
receiving a configuration with a list of pairs of P0 and alpha for an uplink Bandwidth Part (BWP) of a first serving cell with multiple transmission/reception points (TRPs) comprising at least a first TRP and a second TRP, wherein the pairs of P0 and alpha are open loop power control parameters for Physical Uplink Shared Channel (PUSCH) transmission;
when the UE determines that both a first Power Headroom (PH) for the first TRP and a second PH for the second TRP are based on reference formats or both the first PH for the first TRP and the second PH for the second TRP are virtual PH:
computing the first PH for the first TRP based on at least a first pair of P0 and alpha associated with a lowest index or ID of entry in the list;
computing the second PH for the second TRP based on at least a second pair of P0 and alpha associated with a second lowest index or ID of entry in the list; and
transmitting both information of the first PH and information of the second PH indicated via a Medium Access Control (MAC) Control Element (CE).
