1. A method of a User Equipment (UE), the method comprising:
receiving a first uplink grant, associated with a first Transmission/Reception Point (TRP), scheduling or activating or configuring a first Physical Uplink Shared Channel (PUSCH) transmission on a first serving cell;
receiving a second uplink grant, associated with a second TRP, scheduling or activating or configuring a second PUSCH transmission on the first serving cell, wherein:
the first PUSCH transmission is associated with a first Timing Advance (TA);
the second PUSCH transmission is associated with a second TA; and
the first PUSCH transmission at least partially overlaps with the second PUSCH transmission in time domain; and
based on a comparison of a TA difference, between the first TA and the second TA, with a first threshold:
transmitting the first PUSCH transmission, associated with the first TRP, on the first serving cell and dropping the second PUSCH transmission, associated with the second TRP, from transmission on the first serving cell based on the TA difference being larger than the first threshold; or
performing concurrent transmission of the first PUSCH transmission, associated with the first TRP, on the first serving cell and the second PUSCH transmission, associated with the second TRP, on the first serving cell based on the TA difference being smaller than or equal to the first threshold,
wherein the first PUSCH transmission is transmitted with a first transmit power and the second PUSCH transmission is transmitted with a second transmit power if a combination of the first transmit power of the first PUSCH transmission and the second transmit power of the second PUSCH transmission is smaller than or equal to a second threshold.
