Method and apparatus for pathloss derivation for beam operation in a wireless communication system
First Claim
1. A method of deriving UE transmit power for UL (Uplink) transmission to a Transmission/Reception Point (TRP), comprising:
- a UE derives a first pathloss value measured from a first reference signal;
the UE derives a second pathloss value measured from a second reference signal;
the UE transmits a first UL transmission to the TRP wherein a UL transmit power of the first UL transmission is derived from the first pathloss value; and
the UE transmits a second UL transmission to the same TRP wherein a UL transmit power of the second UL transmission is derived from the second pathloss value; and
wherein the first reference signal and the second reference signal are different types of reference signals.

Abstract
A method and apparatus are disclosed, from the perspective of the UE, for deriving UE transmit power. In one embodiment, the method includes the UE deriving a first pathloss value measured from a first reference signal. In addition, the method includes the UE deriving a second pathloss value measured from a second reference signal. The method also includes the UE transmitting a first UL transmission wherein the UL transmit power of the first UL transmission is derived from the first pathloss value. The method further includes the UE transmitting a second UL transmission wherein the UL transmit power of the second UL transmission is derived from the second pathloss value.
